The Development of Copper-Coated Urea for Rice Production

Urea is the main fertilizer used in the rice production in the world. Like other N fertilizers, the efficiency of urea in rice soils generally low due to high losses through volatilization, denitrification and leaching. Slow release fertilizers can be used to minimize loss of N. The rice yields i...

The objective of this study is to develop Cu-coated urea to increase the rice production. In this study, five types of materials consisting chitosan, poly-vinyl chloride (PVC), palm oil sludge (POS), neem oil (NE) and palm stearin (PS) were used as coating materials and Cu carrier.
