aluminum phosphateTanaka Chu, but it was first formed in the water fieldTanaka ChuColloidal amorphous iron and aluminum phosphate are still effective on rice. Secondly, soil clay is common in red and yellow soil to calcium.Tanaka Chuadsorption fixationTanaka Chu, reduce the efficiency of phosphate fertilizer. Applying lime to acidic soil can reduce chemical fixation and physicochemical fixation. This is an important measure to improve the effectiveness of phosphate fertilizer. Although superphosphate is acidic, it tends to be physiologically neutral. Therefore, it has little effect on soil pH after application.
There are three materials in the 2020 Tanaka Junior High School Freshman Summer Life Report Form. Please read and properly keep it carefully. Step 4, registration is over. If you have any other doubts after leaving campus.
Use too much calcium superphosphateTanaka ChuAfter superphosphate is applied to the soil, the water-soluble monocalcium phosphate in the fertilizer is fixed by phosphorus. It is mainly converted into dicalcium phosphate octacalcium phosphate in calcareous soil. Finally, most of it forms stable insoluble apatite. In acidic soil, soluble phosphorus in phosphate fertilizers mainly forms insoluble iron and aluminum phosphate, but the colloidal amorphous iron and aluminum phosphate initially formed in the water field is still effective for rice.
At 6:30 p.m. on October 30, at Picture 311, Teacher Tanaka was a guest in the 31st issue of the real-life book. With his modest, candid and humorous conversation, he brought everyone a "weak book" to talk about me.
In acidic soil, the soluble phosphorus in phosphate fertilizer mainly forms insoluble iron and aluminum phosphate, but the colloidal amorphous iron and aluminum phosphate initially formed in the water field is still effective for rice. Secondly, soil clay particles generally absorb and fix calcium, reducing the efficiency of phosphate fertilizer. Applying lime to acidic soil can reduce chemical fixation and physicochemical fixation. This is an important measure to improve the effectiveness of phosphate fertilizer. Although calcium superphosphate is acidic, it is also an important measure to improve the effectiveness of phosphate fertilizer.
