For Immediate Release Date: 21 June 2024  [Hamilton, New Zealand] – One of New Zealand’s most renowned experts in soil fertility, Dr Gordon Rajendram, today issued an urgent call for greater competition and innovation within New Zealand’s fertiliser industry to bring product prices down. Dr Rajendram, who is a prominent speaker at rural industry forums throughout New Zealand, says his observations highlight a severe lack of competition leading to ongoing high fertiliser prices, stifled innovation, and a worrying lack of change in the fertiliser sector. “The fertiliser market in New Zealand is dominated by a few key players, resulting in limited choices for consumers and consistently high prices,” says Dr Rajendram. “This monopoly-like situation sharpens awareness but also makes companies lazy, relying on their established market positions rather than striving for improvement. Many of these companies are selling the same products they did in the 1950s, with little to no innovation. Super phosphate, has done more for New Zealand’s economy than any politician ever has, but it’s time for change.” The current market shows fertiliser prices still above pre-COVID levels, with super phosphate approximately at $425 per tonne and urea at $795 per tonne. Farmers are now starting to look for alternatives due to these high prices and question marks over environmental aspects of traditional fertiliser products. “In the past, it was more about growing as much pasture as possible. Now, it’s also important to ensure whatever you apply doesn’t run off and leach, causing environmental issues,” adds Dr Rajendram. This shift in focus from merely growing pasture or crops to keeping nutrients in the soil requires more efficient, low phosphate, and slow-release fertilisers that are less water soluble. “A prime example of the benefits of competition can be seen in the dairy industry, where the presence of multiple companies has led to significant advancements in product quality and efficiency. “The fertiliser industry could learn a lot from this. Innovation is essential for addressing the evolving needs of modern agriculture, particularly in a country like New Zealand, where farming is a cornerstone of the economy, Dr Rajendram said. “Currently, the focus seems to be on maintaining the status quo but Rajendram says that the agricultural sector requires fertilisers that are not only effective but also environmentally sustainable. Without competition, there is little incentive for any company to move forward and innovate,” he said. Dr Rajendram emphasises the need for urgent industry transformation to prevent it from becoming a sunset industry. “Competition sharpens everyone’s prices and forces companies to offer better products,” he says. “In conclusion, the New Zealand fertiliser industry needs a shake-up. More competition will lead to better products, fairer prices, and ultimately, a stronger agricultural sector. It’s time for fertiliser companies to stop resting on their laurels and start driving the innovation that our farmers need,” Dr Rajendram says.

The Wairepo Catchment Group and the Omarama Stream Water Users Group of Mackenzie Country recently hosted a presentation titled “Advancing Sustainable Agriculture in New Zealand.” The event featured Dr Gordon Rajendram, a soil scientist and independent consultant, and Allan Piercy, managing director of Agraforum New Zealand. Held on 29 April 2024 in Twizel. The talk emphasised the urgent need to reduce nitrate N leaching by half to maintain farming consents, given the region’s low rainfall, cold winters, and predominant dairying, cattle and sheep farming. In order to farm sustainability in this area, there needs to be a whole catchment approach. Dr Rajendram explained that the area’s soils, with an Anion Storage Capacity (ASC) averaging around 15% and low Cation Exchange Capacity (CEC), are not conducive to retaining nutrients. This results in significant leaching losses, especially with higher stocking rates and cattle grazing on pastoral land. Nutrient loading rates in urine patches can be as high as 600-900 kg of nitrogen and potassium, which penetrate below the pasture root zone and leach into waterways. Twizel experiences low annual rainfall, averaging around 700 mm, and cold temperatures, with winter lows often dropping below freezing. “These conditions hinder nutrient retention and increase the likelihood of leaching. The region relies on irrigation, which is vital for pasture production.” Dr Rajendram emphasised the importance of water availability for effective farming and practical solutions such as using biochar/humates (pure carbon source) to bind nitrogen and other nutrients, use of stand off pads/herd homes to reduce urination events on paddocks or reducing cattle/cow numbers to mitigate environmental impacts. If for instance the cattle were on stand off pads or a herd home for half a day, the nitrate leaching into water ways will reduce by half of what it is at present. Dr. Rajendram explained that if pure carbon such as Biochar was used and was incorporated into the soil to achieve an approximate 10% biochar/90% soil ratio, it would reduce nitrate leaching down to zero. Any farmer can make biochar from Wilding pines which is a pest in the Mackenzie basin.  Rajendram explains that Trevor Richards of Biochar NZ gave a practical demonstration on a Twizel farm on making biochar in pits using Wilding pines.    Allan Piercy’s Contributions from Agraforum New Zealand Following Dr Rajendram’s presentation, Allan Piercy discussed Agraforum New Zealand’s role in providing solutions to nitrate N leaching. Piercy introduced several key products designed to enhance pasture production while reducing fertiliser dependency. A highlight of his talk was El-I-Tech’s Biodynamic N, a product that facilitates biological nitrogen fixation, significantly reducing the need for synthetic fertilisers. Piercy emphasised that integrating these products into nutrient management plans can significantly reduce nutrient leaching and improve soil health. Other notable products mentioned included: “Our products offer a practical solution to nutrient management challenges, helping farmers reduce leaching and improve soil health for long-term sustainability.” – Allan Piercy, Managing Director of Agraforum New Zealand Agraforum New Zealand’s focus on sustainable farming practices ensures that their solutions not only address immediate nutrient retention issues but also contribute to long-term soil health and productivity. These insights and solutions provide a comprehensive approach to tackling the nitrate N leaching challenge in Twizel, ensuring sustainable and productive farming practices.

Volcanic soils, rich in unique minerals such as allophane, play a pivotal role in New Zealand’s agricultural success and environmental sustainability. Dr. Gordon Rajendram, a leading soil scientist, explains that allophane, an amorphous mineral found predominantly in the volcanic ash soils of regions like Waikato and Taranaki, significantly enhances carbon sequestration capabilities, which is crucial in the fight against climate change. Carbon sequestration in soils is a natural way of removing carbon dioxide from the atmosphere and storing it in a solid form. In New Zealand, volcanic soils have demonstrated a remarkable ability to store carbon, with carbon levels reaching 10-12% in some areas. This high organic content not only bolsters soil fertility but also contributes to a healthier microbial environment, which is essential for sustainable agricultural practices. “Allophane’s structure allows these soils to lock in carbon effectively, making them less prone to the typical losses seen in other soil types,” Dr. Rajendram notes. “This characteristic is vitally important for maintaining soil health and long-term agricultural productivity.” Moreover, the presence of allophane influences the physical properties of soil, such as texture and water retention, which are beneficial for plant growth. Its ability to bind with organic matter reduces the rate at which carbon decomposes, thereby keeping it stored in the soil for longer periods. This process not only improves the soil’s structure but also its resistance to erosion and degradation. Dr. Rajendram underscores that understanding the interaction between allophane and organic carbon offers significant insights into sustainable land management practices. By promoting the health of volcanic soils, New Zealand can continue to lead in sustainable agriculture, leveraging its unique geological assets to benefit both the environment and farming communities. The ongoing research and management strategies aimed at enhancing carbon sequestration in these soils not only address global environmental concerns but also support the agricultural sector crucial to New Zealand’s economy.

The rich tapestry of New Zealand’s soil types offers a unique canvas for various farming styles and types of produce, each adapted to the specific characteristics of local soils. From the volcanic terrains of the North Island to the sedimentary expanses of the South, Dr Gordon Rajendram understands that leveraging these soil properties is key to optimising agricultural productivity and sustainability. In the North Island, the volcanic soils, particularly those in Waikato and Taranaki, are highly prized for their fertility. These soils are rich in allophane, a mineral that enhances nutrient and water retention, making them ideal for dairy farming. Dr Gordon Rajendram, states, “The exceptional structure of volcanic soils supports robust root systems, which is crucial for pasture-based dairy farming—a predominant agricultural activity in these regions.” Sedimentary soils, which are widespread in the Canterbury plains of the South Island, present different challenges and opportunities. These soils, with typically lower organic matter, are more prone to nutrient depletion and require careful management to support intensive farming practices. “In Canterbury, the sedimentary soils are primarily utilised for dairy farming as well, but the approach here focuses heavily on soil conservation techniques to prevent erosion and maintain soil health,” explains Dr Rajendram. Additionally, New Zealand’s varied climate and soil types allow for diverse horticultural pursuits. Peaty soils in wetter areas, like parts of Waikato, are especially suited for cultivating specialty crops such as berries and market vegetables, which thrive in the moisture-retentive, nutrient-rich conditions. In contrast, the drier regions, with their clay-rich soils, are excellent for vineyards and orchards, where controlled water retention is beneficial. Understanding these soil-specific requirements has led to tailored farming practices across New Zealand. From rotational grazing that minimizes soil compaction in dairy regions to precision agriculture techniques that enhance crop yields in horticultural areas, farmers are adapting their methods to ensure that they are working in harmony with their environment. “By matching farming practices with soil types, New Zealand’s farmers can maximise both yield and sustainability, securing the agricultural industry’s future and preserving the natural health of our landscapes,” concludes Dr Rajendram. Dr Rajendram feels that this focused approach to agriculture ensures that New Zealand not only maintains its reputation for high-quality produce but also protects its natural resources for future generations.  Contact Dr Gordon Rajendram 021 466077 rajendram@xtra.co.nz www.gordonrajendramsoilscientist.co.nz Contact Phillip Quay phillip@mediapa.co.nz 027 458 7724 www.mediapa.co.nz

Dr. Gordon Rajendram, a renowned authority in soil science and agricultural sustainability, sheds light on the invaluable benefits of clover as a superior feed option for livestock. With its nutrient-rich composition and impressive protein content, clover stands out as a key ingredient in optimising animal diets for enhanced productivity. Comparing clover to ryegrass, a common forage choice, reveals the significant nutritional advantage that clover offers. While ryegrass typically contains around 3.0% nitrogen, resulting in approximately 19% protein content, clover boasts a nitrogen content of approximately 5.5%, translating to an impressive 34% protein content. This stark contrast underscores the potency of clover as a high-quality protein source, capable of providing essential nutrients to support the growth and development of livestock. “Clover stands as nature’s gift to livestock farming, offering a nutritional powerhouse that elevates milk and meat production to new heights. As we strive for agricultural sustainability, harnessing the potential of clover as a superior feed option is not just advantageous; it’s essential for maximising productivity and ensuring the well-being of our animals.” – Dr. Gordon Rajendram The higher protein content in clover which is 34% holds immense significance for dairy and meat producers alike. Protein plays a crucial role in animal nutrition, serving as a building block for muscle development, milk production, and overall health. By incorporating clover into the diet, farmers can ensure that their livestock receive adequate protein levels, thereby promoting optimal growth and maximising productivity. Moreover, clover offers additional nutritional advantages beyond its protein content. Compared to ryegrass, clover exhibits higher mineral content and enhanced digestibility, further augmenting its suitability as a premium feed option. These qualities not only contribute to the overall health and well-being of livestock but also facilitate efficient nutrient absorption, leading to improved feed conversion rates and reduced wastage. In practical terms, integrating clover into livestock diets can yield tangible benefits for farmers. Increased protein intake translates to higher milk yields in dairy cows and improved weight gain in meat-producing animals, ultimately enhancing farm profitability and sustainability. Additionally, the superior nutritional profile of clover can reduce the reliance on supplemental feed additives, thereby lowering production costs and minimising environmental impact. As farmers strive to optimise their operations and meet the growing demand for high-quality dairy and meat products, the role of feed quality cannot be overstated. Dr. Gordon Rajendram’s insights underscore the pivotal role that clover plays as a superior feed option, offering a potent combination of protein, minerals, and digestibility. By harnessing the power of clover, farmers can unlock the full potential of their livestock, paving the way for a more prosperous and sustainable agricultural future.

With his expertise in soil health and fertilisation practices, Dr. Rajendram emphasises the critical role of ASC in optimising agricultural productivity and environmental sustainability. ASC, or P-retention, refers to the soil’s ability to remove phosphorus (P) from the soil solution, thereby holding it firmly and making it less available to plants. This characteristic is largely influenced by soil mineral composition, particularly the presence of iron (Fe) and aluminium (Al), which act as binding agents for P. Soils with low ASC exhibit minimal P binding sites, potentially leading to nutrient leaching and reduced plant uptake. “Anion Storage Capacity (ASC) is the silent guardian of soil fertility, holding the key to sustainable agriculture. In a world where economic uncertainties loom large, understanding and enhancing ASC becomes imperative for farmers. By unlocking the potential of ASC through targeted soil management, we not only cultivate resilience in our farms but also nurture a healthier planet for generations to come.” – Dr. Gordon Rajendram In New Zealand, where farming practices are integral to the economy and food production, maintaining optimal soil fertility is paramount. However, amidst economic challenges such as recession and inflation, ensuring soil health becomes even more imperative for farmers striving to maintain profitability and sustainability. Understanding ASC is crucial for effective fertilisation strategies and soil management practices. By assessing ASC levels through soil testing, farmers can tailor their fertiliser applications to match the specific needs of their soils, thereby maximising nutrient utilisation and minimising environmental impact. Dr. Rajendram’s research underscores the importance of ASC in soil fertility management and its implications for farm profitability and environmental stewardship. By enhancing ASC through targeted soil amendments and conservation practices, farmers can improve nutrient retention, reduce nutrient runoff, and safeguard water quality. Moreover, prioritising soil health and ASC optimisation aligns with efforts to reduce the environmental footprint of agriculture. By minimising nutrient losses and enhancing nutrient cycling within the soil-plant system, farmers can contribute to the preservation of natural resources and ecosystems. In conclusion, Anion Storage Capacity (ASC) plays a pivotal role in soil fertility management and agricultural sustainability. Through the expertise of leading soil scientists like Dr. Gordon Rajendram and the adoption of innovative soil management practices, New Zealand farmers can navigate economic challenges while safeguarding soil health and enhancing farm resilience for future generations.

In New Zealand, where farming practices are integral to the economy and food production, soil fertility plays a pivotal role in determining the success of agricultural endeavours. However, amidst economic challenges such as recession and inflation, ensuring optimal soil health becomes even more imperative for farmers striving to maintain productivity and profitability. Phosphate, a key component of soil fertility, serves as a vital nutrient for plant growth and development. Its presence in the soil is essential for facilitating various biochemical processes necessary for crop production and pasture growth. Through soil testing and fertiliser recommendations, experts like Dr Rajendram help farmers assess and address deficiencies in phosphate levels, ensuring that their land remains fertile and productive. “Phosphate, the silent hero beneath our feet, holds the key to unlocking the potential of our soil. In a world of economic uncertainties, its role in maintaining soil fertility becomes paramount. By nurturing this vital nutrient, we not only cultivate bountiful harvests but also sow the seeds of sustainability for generations to come.” – Dr. Gordon Rajendram By maintaining adequate phosphate levels in the soil, farmers can optimise nutrient uptake by crops and pastures, leading to improved yields and enhanced animal nutrition. Pasture testing and feed analysis further aid in fine-tuning nutrient management strategies, ensuring that livestock receive balanced diets essential for growth and performance. Moreover, prioritising soil health and nutrient management not only benefits farm profitability but also contributes to environmental sustainability. By minimising the use of excess fertilisers and adopting precision farming practices, farmers can reduce their environmental footprint and mitigate the risk of nutrient runoff into waterways. Dr. Gordon Rajendram’s expertise in soil science and agricultural practices underscores the importance of proactive soil management in optimising farm productivity and sustainability. Through ongoing research and education initiatives, he continues to empower farmers with the knowledge and tools needed to safeguard soil health and enhance agricultural resilience in the face of evolving challenges. In conclusion, phosphate stands as a cornerstone of soil fertility, supporting vibrant farming ecosystems and ensuring food security for future generations. By heeding the insights of leading soil scientists like Dr Rajendram and prioritising soil health in farming practices, New Zealand farmers can navigate economic fluctuations while fostering a more sustainable and prosperous agricultural landscape.

Soil structure plays a pivotal role in determining the agricultural productivity and sustainability of New Zealand’s diverse landscapes. Dr. Gordon Rajendram, a leading soil scientist, examines how the structural integrity of soil affects everything from water retention and drainage to root development and nutrient uptake. Understanding these differences is crucial for effective farm management and long-term soil health. In New Zealand, soil structure varies significantly not only between the volcanic soils in regions such as Waikato and Taranaki, and the sedimentary soils found predominantly in areas like Canterbury but also across other soil types such as peaty soils in wetter regions and clay soils in drier areas. Volcanic soils benefit from a loose, porous structure due to the presence of allophane, a mineral that not only enhances soil stability but also aids in significant carbon storage, with carbon levels reaching 10-12%, thereby enriching the soil’s organic content. This structure promotes excellent water retention and nutrient availability, making these soils ideal for high-demand agricultural activities, such as dairy farming. Conversely, sedimentary soils present different challenges. Dr. Rajendram explains, “Sedimentary soils tend to be denser and can suffer from compaction more easily, which reduces aeration and negatively impacts root penetration and moisture permeability.” These soils typically have lower organic matter content, generally around 3-5% carbon, making them more prone to degradation. which can lead to faster degradation and fertility loss over time if not managed correctly. Peaty soils, while excellent for specific horticultural uses due to their high organic matter content, require careful water management to prevent over-saturation, which can suffocate plant roots. Similarly, clay soils, known for their ability to retain water, are advantageous in drier regions but can become hard and crack when dry, posing challenges for root growth and soil aeration. Effective management practices are essential for maintaining the health of all these soil types. Dr. Rajendram highlights that strategies such as regular soil testing, appropriate crop rotation, and the careful application of organic amendments are vital. For volcanic soils, maintaining the structural integrity involves minimal tilling and controlled grazing to prevent compaction. For sedimentary soils, improving structure may involve more frequent organic matter addition and careful water management to avoid surface crusting and compaction. Dr. Rajendram emphasises that by tailoring farming practices to the specific type of soil structure, New Zealand farmers can enhance productivity and ensure the sustainability of their valuable agricultural lands.  Contact Dr Gordon Rajendram 021 466077 rajendram@xtra.co.nz www.gordonrajendramsoilscientist.co.nz Contact Phillip Quay phillip@mediapa.co.nz 027 458 7724 www.mediapa.co.nz

In the verdant landscapes of New Zealand, where agriculture forms the backbone of the economy, maintaining the right balance of nutrients in the soil is critical for both crop yield and environmental sustainability. Dr Gordon Rajendram, a renowned soil scientist, draws attention to an often-overlooked issue: the signs of excessive phosphate levels in the soil, a condition that can have far-reaching consequences for both agriculture and natural ecosystems. Phosphate is an essential nutrient for plant growth, but like anything in excess, it can lead to problematic outcomes. One of the primary signs of too much phosphate in the soil is the inhibition of plant uptake of other necessary minerals, such as iron, zinc, and manganese. This nutrient imbalance can result in poor plant health and reduced growth, a paradoxical situation where more is indeed less. Moreover, excessive phosphate can lead to algal blooms in nearby water bodies, as runoff carries the surplus nutrients into rivers and lakes. These blooms not only disrupt aquatic ecosystems but can also pose a risk to animal and human health. In New Zealand, with its extensive coastlines and waterways, this issue is of particular concern, highlighting the need for careful nutrient management. Dr Rajendram points out that soil testing is a crucial step in identifying excessive phosphate levels. Such tests can help farmers and land managers make informed decisions about fertiliser application, reducing unnecessary inputs and mitigating environmental impacts. Another sign of too much phosphate is the appearance of certain weed species that thrive in high-phosphate conditions. These weeds can outcompete crops and native plants, further disrupting agricultural productivity and biodiversity. Phosphate holds a pivotal role in the tapestry of soil nutrients, serving as a cornerstone for plant growth and agricultural productivity. Dr Gordon Rajendram emphasises the significance of phosphate, noting, “Phosphate is akin to a key that unlocks the energy potential within plants. It’s essential for photosynthesis, energy transfer, and the synthesis of nucleic acids and cell membranes. Without adequate phosphate, plants cannot thrive or produce at their full potential.” In conclusion, recognising and addressing the signs of excessive phosphate in New Zealand’s soils is a critical step towards sustainable agriculture and environmental stewardship. Through careful management and a commitment to balance, the country can continue to thrive both economically and ecologically.

Nutrient leaching from soil is a significant concern for farmers and environmentalists alike, as it represents both a loss of valuable fertilisers and a potential source of environmental pollution. Dr Gordon Rajendram has provided critical insights into this issue, demonstrating that the amount of nutrients lost via subsurface flow is closely related to the amount of rainfall and drainage. In areas where rainfall and drainage range from 500 to 7000 mm per year, particularly from April to October, nutrients can be washed beyond the root zone, where plants are unable to utilise them. This process is especially problematic for anions like nitrates (NO3-) which are highly mobile and tend to leach easily. Anions also carry cations with them, such as calcium (Ca2+), exacerbating the loss of nutrients. For instance, Dr Rajendram’s research indicates that sulphur leaching can be between 40 to 70 kg/ha/year, costing approximately $28 to $49 per hectare annually. When it comes to nitrogen (N), a critical element for plant growth, the figures are even more striking. Without any nitrogen applied, between 21 to 26 kg/ha/year can leach, amounting to around $43 per hectare each year. However, when 200 kg of nitrogen per hectare is applied, the leached amount can increase to about 60 kg/ha/year, with the cost rising to around $125 per hectare annually. And with a higher application rate of 400N, up to 100 kg N/ha/year may leach, costing approximately $209 per hectare each year. Calcium leaching, which equates to the loss of half a ton of lime, is around 150 kg Ca/ha/year, resulting in a cost of about $13 per hectare per year. Other nutrients like magnesium (Mg), sodium (Na), and potassium (K) also experience significant leaching, with costs of $30, $50, and $19 per hectare per year, respectively, for losses of 30 kg Mg, 50 kg Na, and 10 kg K. Dr Rajendram asserts that to mitigate nutrient leaching, farmers need to employ strategic fertiliser management. This includes soil testing to determine the existing nutrient levels, timing fertiliser applications to match plant needs, and using technologies such as controlled-release fertilisers, nitrification inhibitors and management practices such as using standoff pads/herd homes “Effective nutrient management is key to both economic efficiency and environmental stewardship,” Dr Rajendram advises. “By optimising fertiliser use, we can reduce leaching losses, saving both our resources and our rivers.” This holistic approach to agriculture is essential for sustainable farming practices that protect both the productivity of the land and the health of the environment.
