Preparation and slow-release properties of clay-based phosphatic fertilizers
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.
