Controlled-release fertilizers provide better uptake by plants, less volatilization, increased yields and profitability
By next year, a new fertilizer plant in Ontario will give Canadian farmers access to 100,000 tonnes per year of controlled-release nitrogen, phosphate and potassium fertilizers, as well as custom blending options. micronutrients.
The St. Thomas plant plans to produce a variety of controlled-release fertilizer, or CRF, once full capacity is reached, according to an Aug. 31 press release from joint venture partners, Sollio Agriculture in Ontario and Pursell Fertilizer in Alabama.
The facility will focus on next generation coating materials and proprietary processing techniques from Pursell. The plant will use new technology that allows the addition of micronutrients and temperature sensitive additives, such as biologics, growth promoters and soil health promoters.
According to the International Fertilizer Association, using CRF could reduce the recommended rate of a conventional fertilizer by 30 percent while achieving the same yield. Farmers have started using CRFs because they provide a more predictable and precise curve, which helps control release time.
Growers using CRFs save money by being able to reduce fertilizer applications, add more micronutrients, and improve overall plant and soil health.
The IFA claims that CRFs improve nutrient uptake by plants, with the potential to dramatically improve yield and quality while reducing greenhouse gas emissions from volatilization and reducing the risk of leaching and runoff of nutrients.
Historically, CRF products have been difficult to access for staple agricultural crops such as corn, wheat, canola or potatoes.
According to the release, CRFs were primarily used in lawns and ornamental environments.
Sollio CEO Casper Kaastra says local manufacturing cuts logistics expenses and allows the company to offer CRF products previously unavailable in this market.
âA plant in St. Thomas is ideal. It is located close to the suppliers of substrates and materials and creates opportunities for retailers to meet the diverse nutritional needs of their customers.
Sollio researcher Lucie Kablan said the company had tested CRFs on its research farm for four years and found that a pre-planting coated urea application of Pursell’s new technology significantly increased yield and the profitability of corn.
âWe are conducting promising trials on coated phosphorus and muriate of potash. We have partnered with McGill University to assess the environmental benefits of FRCs in terms of greenhouse gas emissions. This will provide useful data to make recommendations to Canadian farmers.
Kaastra says the project represents an investment of more than C $ 20 million.
Sollio Agriculture specializes in agricultural inputs and value-added agronomic services in the livestock, crop production and cereals sectors.
Pursell’s innovative coating materials and proprietary processing enable fertilizer retailers to provide their customers with customized nutrient blends.
