A Review on Industrial by-products as Materials to Coat Compound Fertilizer

Abstract

Fertilizers play the most important role in agriculture. The uses of compound fertilizers are common to supply nutrients needed by plant. However, with conventional application, nutrients are easily lost due to various factors. Coated compound fertilizers are started to take place in fertilizer management. Different coating materials and coating techniques are explored to hopefully provide better production and fertilizers efficiency. The main purpose of this paper is to explore technologies and sources of coating materials of compound fertilizers and how do they work.
