LaSalle Agri turns recovered nutrients into premium fertilizers that improve soil health, boost yields, and reduce landfill waste for sustainable farming.
With over 3000 municipal solid waste landfills in Canada, the agricultural sector faces significant environmental sustainability challenges. LaSalle Agri Fertilizer, based in Watford, operates as a farmer-founded and farmer-operated company positioned to balance crop performance with long-term soil health. The company's mission involves offering high-quality, sustainable fertilizers that reduce dependency on commercially mined finite resources while minimizing landfill burden across North America.
Soil serves as the foundation of food security, yet decades of intensive farming and chemical fertilizer use have depleted essential nutrients, threatening long-term agricultural productivity. LaSalle Agri collaborates with water resource recovery facilities across North America to reclaim products rich in phosphorus, nitrogen, and potassium—three critical macronutrients vital for plant growth. By reintroducing these nutrients along with important micronutrients and organic matter into soil, the company's premium fertilizer products support immediate crop uptake while contributing to long-term soil health, improved structure, and sustained fertility.
The fertilizers are specifically formulated to support essential staple crops including corn, wheat, and soybeans. Products deliver balanced nutrient profiles, increasing efficiency and promoting healthier soil biology without compromising safety or consistency.
Michaela Tessemaker, general manager of LaSalle Agri Inc., states: “Every pound of phosphorus or nitrogen we recover from waste is a pound that doesn’t need to be mined or synthetically produced.”
What distinguishes LaSalle Agri is its emphasis on customer service, field expertise, and results-driven solutions. The company manages the entire process from timely on-farm delivery to custom land application using specialized, farmer-designed equipment, ensuring precise and efficient application. This turnkey approach helps farmers achieve optimal outcomes without added complexity.
By converting residuals into nutrient-rich fertilizers through innovative waste-recovery practices, LaSalle Agri delivers products formulated to support long-term soil vitality. With deep roots in farming and commitment to environmental responsibility, the company combines practical experience with advanced solutions to meet modern agriculture's evolving needs. Farmers report not only improved yields but also reduced reliance on chemical inputs, aligning with increasing consumer demand for premium fertilizer solutions.
The company offers custom equipment solutions designed for efficient, accurate application, ensuring nutrients are delivered at the right rate, time, and placement aligned with the 4Rs of Nutrient Stewardship.
Committed to eco-friendly solutions, LaSalle Agri emphasizes a science-backed, evidence-based approach. The company aims to play a role in sustainable farming's future by providing fertilizers that boost yields while safeguarding land for future generations, with strong focus on long-term sustainability of soil and water systems.
