Abstract
A method for producing organic compound mixed fertilizer is carried out by sampling sludge, drying, crushing, screening with 60 meshes, adding nitrogen fertilizer, phosphatic fertilizer and potassic fertilizer into papermaking sludge proportionally, mixing with two end feed by fertilizer mixer and packing. The organic composite mixed fertilizer consists of sludge 70-85wt%, nitrogen fertilizer 5-15wt%, phosphatic fertilizer 3-8wt% and potassic fertilizer 5-15wt%. Its advantages include low cost, simple process and better economic benefit, to improve soil physical structure and plant growth.
