Abstract
Field experiments, designed to evaluate the effect of direct application of phosphate rock, were carried out on red soil (Ultisol) uplands at three different places. The results indicated: (1) for the first year's crop, the rapeseed yields with phosphate rock treatment and triple superphosphate treatment were almost identical when their rate of phosphorus application was the same; (2) when the same level of phosphorus fertilizer was applied, the residual effect of phosphate rock was better than that of triple superphosphate, and the residual effect of all phosphorus fertilizers on winter crop yields increased with the increase of the amount of Phosphorus applied; (3) with the application of phosphate rock, the pH value, the amount of available phosphorus and exchangeable Ca and Mg of soils went up, whereas the content of active Al in soils decreased. Therefore, the direct application of phosphate rock to red soil also has an important role in improving soil properties.
