Such factors limit the use of rock phosphates for direct application, so that much greater knowledge of the characteristics of the phosphates, soils and crops, and their interactions, is necessary for their successful use than for the soluble phosphates. different qualities in the world (Hammond and Day, 1992). time. | Sitemap.

Notably, the Cd input from phosphate fertilizer in Henan Province was high, with a total input amount of 144.3 kg/y, which was the highest in China, and the lowest input occurred in Beijing in northern China.
