(1) the most suitable for basal deep soil. Calcium-magnesia phosphate fertilizer applied into the soil, which can only be weak acid phosphorus dissolving, go through certain transformation process, the crops can be used, applied so slow, slow release fertilizer. Will generally want to combine agriculture, fertilizer evenly into the soil, make it is mixed with soil, for the soil acid dissolution of it, and good for crops to absorb it.
