Abstract
With potassium dihydrogen phosphate acting as raw material, using grinding and adsorption methods to prepare diffrent kinds of clay-based phosphatic fertilizers. And later, using sodium alginate to coat the fertilizers. Choosing soil leaching method to evaluate their slow-release properties. The results indicate that carrier properties have great influences on slow-release properties, the effect of different carriers are as follows: bentonite > kaolin> common earth. The coordinated role of bentonite and hydrotalcite to the slow-release properties is better than the single role of bentonite. The coating of sodium alginate can improve the slow-release properties of clay-based fertilizers.
