Abstract
A fertilizer-application method comprises (a) receiving an aqueous solution of a cyanamide compound into a heated segment of a hydrolyzer; (b) allowing the cyanamide compound to hydrolyze in the heated segment, thereby forming an aqueous cyanamide hydrolysate (ACH); (c) allowing the ACH to cool under pressure; and (d) applying the ACH, after cooling, to soil.
Claims10
Farm equipment configured for fertilizer application, the equipment comprising:
- a tank configured to store an aqueous solution of a cyanamide compound;
- a hydrolyzer including an upstream segment configured to receive and heat the aqueous solution, thereby forming an aqueous cyanamide hydrolysate (ACH), and a downstream segment configured to cool the ACH under pressure,
- wherein the equipment is configured to release the cooled ACH, comprising both nitrogen and carbon, to soil.
