When urea fertiliser is applied to pasture, it undergoes a series of chemical transformations vital for plant growth. Profile Fertilisers ensures these processes are managed efficiently to maximise yield and minimise environmental impact, offering advanced solutions backed by the latest agricultural research.
Urea, a concentrated form of nitrogen (typically 46% nitrogen by weight), is initially broken down by the enzyme urease, naturally present in soil. This hydrolysis process converts urea into ammonium (NH4+), a form of nitrogen, which is then converted to nitrate (NO3-) which the plant can then uptake. The reaction’s speed is influenced by soil temperature, moisture, and pH levels. Profile Fertilisers provides expert advice on optimal application timing, helping prevent nitrogen loss and improve nutrient uptake by plants.
Once ammonium is formed, it can either be absorbed directly by plants which is a small proportion compared to most of the applied nitrogen which undergoes nitrification, where soil bacteria convert it into nitrate (NO3-), which is the most plant-usable nitrogen form. Nitrate is highly mobile, prone to leaching. Research shows that the nitrogen applied, that only 1% of this nitrate is directly leached, and most of the leaching is due to nitrate from the urinary nitrogen excreted by animals. Applied urea can also be lost into the atmosphere as a gaseous nitrogen forms like nitrous oxide (N2O), a potent greenhouse gas. Research shows up to 50% of applied nitrogen can be lost if not properly managed. Profile Fertilisers’ products are designed to optimise nitrogen use efficiency, reducing losses and ensuring more nitrogen is available for plants.
Urea efficiency can be enhanced through strategic application, such as applying it before rainfall to incorporate fertiliser into the soil. This practice reduces nitrogen loss through volatilisation, where nitrogen escapes as ammonia gas. Profile Fertilisers offers tailored solutions and guidance to ensure your pasture receives the right nitrogen at the right time, maximising growth and minimising environmental impact.
In summary, urea is an effective nitrogen source for pastures, but its efficiency depends on careful management. Profile Fertilisers provides the expertise, products, and support to optimise nitrogen application, ensuring sustainable and productive pasture management.
An anonymous Hamilton-based farmer has supported the call for more competition in the fertiliser industry from renowned Hamilton soil scientist Dr Gordon Rajendram.

“Improving soil biology with less environmental impact is a significant step forward. Improving productivity is one of the most important things any nation can do to help its people, so I think competition and new ways are great,” the farmer said.
“Furthermore, with increasing restrictions and tighter compliance standards being put on farmers, you are providing them with a choice and making it sustainable over the long term,” he said.
Dr Gordon Rajendram has been vocal about the critical need for increased competition in the New Zealand fertiliser market. According to Dr Rajendram, the current market dynamics stifle innovation and result in higher costs for farmers, ultimately impacting the agricultural sector’s sustainability and productivity.
The farmer emphasised the intense pressure faced by those in the dairy sector, where compliance with stringent environmental standards is a constant challenge. “Being in dairy, I am aware of how much pressure farmers are under from all sorts of things, so innovation and alternative choices are great for this sector.”
Dr Rajendram’s research underscores the importance of soil biology in enhancing productivity while minimising environmental impact. “By focusing on improving soil health through innovative fertilisers, we can achieve higher yields with less environmental degradation,” he explains.
“More competition in the fertiliser market would lead to lower prices and better products for farmers,” Dr Rajendram asserts. “This is crucial not only for improving soil health but also for meeting the stringent environmental standards imposed on the farming community.”
One of the key issues Dr Rajendram highlights is the limited number of players in the fertiliser industry, which leads to a lack of incentive for companies to innovate and offer environmentally friendly products. With New Zealand’s farmers facing increasing pressures from both regulatory bodies and market forces, the need for cost-effective and sustainable fertiliser options has never been greater.
In conclusion, Dr Rajendram’s call for more competition in the fertiliser market is not just about reducing costs; it’s about fostering a culture of innovation that benefits both farmers and the environment. As New Zealand continues to strive for more sustainable farming practices, embracing competition and encouraging innovation in the fertiliser sector will be key to achieving these goals.

Hamilton, New Zealand – August 6, 2024 – Recent trials conducted by Dr Gordon Rajendram, a distinguished soil scientist and consultant, have revealed significant improvements in pasture production on Canterbury dairy farms through the use of soil compaction treatments. Dr Rajendram, formerly of AgResearch and MAF, led these trials to assess the impact of soil compaction on pasture growth and to demonstrate the effectiveness of Agraforum’s soil treatments. Dr Rajendram stated that “The trials have shown that addressing soil compaction through targeted treatments can significantly enhance pasture production, providing a sustainable solution for farmers to boost their productivity.”

Pasture production is influenced by five primary factors (1):
1. Soil Moisture: Adequate rainfall or irrigation is crucial, with less than 25% soil moisture negatively impacting growth.
2. Soil Temperature: Grass growth ceases when the soil temperature at 10 cm depth falls to 5-6 degrees Celsius.
3. Soil pH and Nutrients: Thirteen essential elements for plant growth, along with Co, Se, and I for animal health, are vital.
5. Soil Air Space (Air-Filled Porosity or Macroporosity): Compacted soil, with less than 10% air-filled porosity (AFP), significantly reduces pasture production. Each percentage drop below this threshold results in a 10% reduction in yield (based on AgResearch trials)(2).
Since 1995, the Waikato Regional Council has been monitoring soil quality at 150 sites across the Waikato region, focusing on volcanic ash and pumice soils used for dairying, beef, cropping, and forestry. Seven soil quality tests are conducted at each site, including air-filled porosity. The 2019 data revealed that 94% of dairy farming sites had concerning soil quality, with excessively high fertility and soil compaction affecting approximately 85% of the sites. (Waikato Regional Council)(3).
Aim and Methodology
The aim of the trials was to demonstrate that Agraforum’s soil compaction treatment can improve soil aeration and pasture growth. The trials involved:
– Four irrigated Canterbury dairy farms, with two using Agraforum’s treatments for several years and two untreated.
– Monthly pasture measurements using a ride-on mower and digital scales.
– Soil temperature monitoring, starting at 14 degrees Celsius and dropping to 5 degrees Celsius by the third cut.
Each farm had ten plots (2m x 10m), and the trials commenced in the last week of February 2024, with pasture cuts taken over a 105-day autumn period.
Findings
The results were conclusive:
– The two treated farms produced approximately 1,000 kg DM/ha (33%) more dry matter than the best untreated farm.
– Compared to the second untreated and most compacted farm, the treated farms yielded over 2,000 kg DM/ha (80%) more pasture.
Graphs from the study clearly illustrate the superior performance of treated farms in terms of total pasture grown and growth rates, particularly for the first cut.
Graph 1: Shows Total pasture grown for ~ 105 days for the 2 Agraforum Treated and Untreated Farms.
Graph 2: Shows the growth rates for the first cut for the farms. The Treated farms grew twice and 3 times the more pasture than the Untreated farms for the first cut.
Graph 3: Shows the accumulated grass growth across all four farms over the trial period. The treated farms clearly grew significantly more pasture compared to the Untreated farms. Error bars show the 95% confidence interval at each cut, calculated from the ten replicate plots within each farm.

Earthworms are crucial to maintaining healthy soil, significantly enhancing soil structure and fertility. Their natural burrowing activity aerates the soil, improving water infiltration and root development. Fascinatingly, earthworms can consume up to 30 times their body weight in soil daily, which they excrete as nutrient-rich castings, helping to enrich the soil with essential nutrients. A vital component in supporting these beneficial organisms is calcium, a nutrient supplied by Profile Fertilisers’ products.
Profile Fertilisers offers Elevate, a premium calcium-based product designed to boost soil calcium levels. Calcium is vital not only for plant health but also for the well-being of earthworms. It helps neutralise soil acidity, creating a more favourable environment for earthworms to thrive. This, in turn, leads to improved soil structure and fertility, supporting the biological processes necessary for sustainable agriculture.
One of the critical roles of earthworms is their ability to combat soil compaction. Compacted soil can restrict root growth and water absorption, negatively impacting plant health. Earthworms alleviate this by creating channels that allow air and water to penetrate deeper into the soil, reducing compaction and promoting a healthier root environment. The use of Elevate by Profile Fertilisers increases the soil’s calcium content, fostering a robust earthworm population that helps mitigate soil compaction.
The beneficial relationship between earthworms and calcium-enriched soil enhances nutrient cycling, water retention, and soil aeration—key factors for healthy crop growth. Consequently, farmers and gardeners can achieve higher yields while reducing their dependence on chemical fertilisers, thus promoting a more sustainable approach to soil management.
Incorporating Profile Fertilisers’ Elevate into soil management strategies is a wise investment in soil health. By supporting the crucial role of earthworms and ensuring adequate calcium levels, Profile Fertilisers helps cultivate a thriving agricultural environment. This not only benefits the ecosystem but also enhances crop productivity, making it a valuable choice for those committed to sustainable farming practices.
The story of a family and their farm on the coast of Whangarei is one of remarkable resilience and adaptation. Despite numerous challenges, things are on track for a brighter future. Their journey, marked by persistent challenges and setbacks, exemplifies their determination to overcome adversity and secure a better future.
Once owning a farm at Dargaville, the family decided to move closer to Whangarei, purchasing two farms in the general area. However, persistent flooding over the past eight years at one farm forced them to sell their properties to a businessperson from Auckland.
Retaining a 50/50 sharemilking job on their home farm, they were able to purchase an additional 145 hectares on the coast of Whangarei, encompassing 85 hectares of flat land, 46 hectares of hill land, 14 hectares of bush in 4 titles. The 4 titles are encompass 36 ha plus house, 62 ha, 20 ha and 27 ha) with good sea views from parts of the farm. From the back of the farm from a ramp you are able to launch a boat and be in the open ocean in 5 minutes. From this farm you can set a net in the evening, go back in the the morning to find mullet, snapper, trevally, Kahawaii and flounder in the net. They moved to their new farm in March 2017.
The sharemilking job was intended to help pay and develop the new farm. However, within a year, they lost the 50/50 sharemilking job and ended up in court, despite having all the rights. The other side had more money, and their lawyer advised them to leave, resulting in significant financial loss.
In October 2019, disaster struck again when the floodgate on the farm collapsed, allowing seawater to inundate the flatland, killing grass, worms, and 85 large poplar trees, and destroying 60 hectares of grass. They worked tirelessly through the night to install a temporary gate and awaited resource consent to install new gates. In April 2020, they began constructing new floodgates, designed by an engineer and built with the help of family and a late friend.
The family faced further challenges with waterlogged paddocks due to salt contamination and winter rain. Despite these setbacks, they began humping and hollowing paddocks, finishing three paddocks initially. However, complaints from uneducated neighbours to the dairy industry threatened their milk supply, as it was incorrectly understood that it was illegal to carry out this work. The dairy company stated they would stop taking their milk if they continued.
In 2022, they sold livestock to China through Genetic Developments but did not receive payment, resulting in further financial strain.
By September 2023, land productivity remained an issue, prompting them to restart humping and hollowing. Uneducated neighbours complained again to the Regional Council, but the council was impressed with their progress and primarily advised on silt control. They managed to hump and hollow 15 paddocks, with three remaining. Of the 145 hectares, 110 hectares are now effective.
Despite these continuous challenges, the family exemplifies resilience and determination in their ongoing journey to develop their farm and secure their future.
Looking Ahead: A Call for Support
Here lies a beautiful property with coastal views, brimming with potential and on the cusp of full recovery. With the help of Dr Gordon Rajendram, the farm is on its way to recovery. They are now moving on to repairing the hills, with the outlook being much brighter. Production has increased by 20% this year compared to last year and is expected to increase further with other improvements. They are encouraging people to reach out and invest in the property. This farm will be a great asset for anyone who invests, offering both financial returns and the satisfaction of supporting a resilient family and a flourishing agricultural endeavour. With your support, they can continue to improve their farm and secure a prosperous future.
The dairy industry in New Zealand is an essential part of the economy, contributing significantly to the nation’s GDP. However, the environmental impact of dairy farming, particularly the use of nitrogen-based fertilisers like urea, has been a growing concern. Profile Fertilisers is at the forefront of addressing these issues, focusing on the leaching of nitrates into the groundwater, largely due to urine patches left by grazing cows.
Urine patches are a significant source of nitrogen leaching in pasture-based dairy systems. When cows urinate, they deposit a concentrated amount of nitrogen in small areas, resulting in patches where the nitrogen levels can reach up to 1,000 kg/ha. This is far more than the plants can utilise, leading to excess nitrogen that is susceptible to leaching, especially during heavy rainfall.
Studies have shown that nitrogen leaching from urine patches can account for up to 70% of the total nitrate leaching on dairy farms. The extent of leaching is influenced by several factors, including soil type, rainfall, and management practices. For instance, free-draining soils and high rainfall areas are particularly vulnerable to nitrate leaching. Research indicates that the average dairy cow can produce around 250-300 litres of urine per day, contributing significantly to the nitrogen load on pastures.
The leaching of nitrates into surface water bodies can contribute to eutrophication, a process that depletes oxygen in the water and harms aquatic life. It is estimated that nitrate leaching from agricultural sources contributes to 60-80% of the total nitrogen entering water bodies in New Zealand.
Profile Fertilisers, based in Pahiatua, is committed to addressing these challenges by promoting sustainable fertiliser practices. Using slow-release nitrogen fertilisers and implementing precision application techniques can significantly reduce the amount of nitrogen lost to leaching. Additionally, integrating advanced soil testing and monitoring helps optimise nitrogen use, ensuring that it meets the plants’ needs without excess. Slow-release fertilisers have been shown to reduce nitrogen losses by up to 50% compared to conventional urea.
Farmers can also adopt practices such as planting catch crops, which absorb residual nitrogen, and improving irrigation efficiency to reduce nitrate leaching. Implementing strategic grazing management and using nitrification inhibitors can further mitigate nitrogen leaching. By combining these strategies, the dairy industry can move towards more sustainable practices that protect our valuable water resources while maintaining productivity.
Through continuous research and innovation, Profile Fertilisers aims to support the dairy industry in reducing its environmental footprint, ensuring a balanced approach to productivity and sustainability. With the right strategies, the dairy industry can continue to thrive while preserving New Zealand’s pristine environment for future generations.

[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.
Soil Scientist Dr Gordon Rajendram
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.
Dr Gordon Rajendram is a distinguished independent soil scientist with extensive experience in the agricultural sector. His work focuses on improving soil health and sustainability practices in farming, making him a respected voice in the industry.
Agraforum New Zealand, a leader in agricultural innovation, today emphasised the benefits of EnviroCal over traditional mechanical aeration for soil compaction management. Soil compaction is a significant issue affecting crop productivity by limiting root growth, water infiltration, and nutrient absorption. Effective soil aeration is crucial for sustainable agriculture, as it enhances these essential processes. Agraforum’s research and development have led to the development of EnviroCal, a superior solution that addresses soil compaction through chemical means, offering a sustainable, efficient, and long-lasting improvement in soil health.
Allan Piercy and Dr Gordon Rajendram
EnviroCal: The Non-Physical Solution
EnviroCal utilises free unbound calcium to create aeration, unlike bound calcium in lime and gypsum. This approach works quickly, showing results within 4-6 weeks, and offers long-lasting effects without the need for physical intervention. By improving soil structure and reducing compaction, EnviroCal enhances root growth, water infiltration, and nutrient absorption.
The Science Behind EnviroCal
EnviroCal leverages the unique properties of free unbound calcium ions. When applied to the soil, these calcium ions displace magnesium, potassium or sodium ions and bind with soil particles, promoting flocculation. This process helps to create larger soil aggregates, enhancing soil structure and porosity. Improved soil porosity allows for better air and water movement within the soil, which is crucial for healthy root development and efficient nutrient uptake. This scientific mechanism differentiates EnviroCal from traditional calcium sources like lime and gypsum, where calcium is bound and electrically neutralised and less effective in altering soil structure. By increasing available calcium, this also adjusts the electrical charge of soil colloids, promoting aggregation and improving soil health.
Allan Piercy, Directing Manager of Agraforum New Zealand, stated, “EnviroCal offers a non-physical, effective solution for soil compaction, ensuring sustainable soil health. Our focus is to provide farmers with efficient and environmentally friendly options for optimal soil management.”
Mechanical Aeration: A Labour-Intensive and Less Sustainable Approach
While mechanical aeration provides immediate results by physically creating small holes in the soil, it is temporary because you haven’t changed the under lying cause, is labour-intensive and requires frequent repetition, making it less sustainable. The method involves using tools like aerators or tillers to break up compacted soil, allowing air, water, and nutrients to penetrate more effectively. However, the benefits are often short-lived, especially in soils prone to recurrent compaction where the problem is lack of the correct electrical polarity on the individual soil colloids.
