Market gardening crops have high nitrogen requirements. Organic growers, in particular, are hampered by a lack of access to efficient and sustainable nitrogen fertilization options. Most animal fertilizers currently in use are not very effective and are loaded with phosphorus. Commercial products, such as Biosol and Actisol, have gained in popularity, but still contain significant levels of phosphorus and are expensive. Farmers have turned to purchasing alfalfa meal pellets, which have better Neff: / Ptot ratios. In this study, we will test these pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with the two organic fertilizer brands mentioned above, in addition to a control treatment in which no nitrogen is added. The knowledge obtained will contribute to the development of integrated fertilization strategies that will enable farmers to make optimal use of these fertilizer products, while maintaining their market competitiveness.

This project will help determine whether alfalfa meal pellets are an effective organic farming fertilizer.
