A method is provided for producing a biochar solution. The method comprises the steps of collecting biochar particles, dispersing the biochar particles in a liquid solution and adding a stabilizing agent to keep the biochar in flowable suspension. The stabilizing agent may be added to the liquid solution or to the biochar prior to placing the biochar in solution.

A wax-based coating for fertilizer granules capable of supplying micronutrients to soil while increasing the surface hydrophobicity and abrasion resistance of the fertilizer granules is disclosed. The wax-based coating provides the flexibility of formulating slow and fast releasing micronutrients, and ensures micronutrients are evenly coated across every fertilizer granule. Single or multi-nutrient combinations of coatings are possible, providing formulation flexibility.
