有機磷肥級磷酸氫鈣又名白磷肥還是白肥，是工作飼料廠級磷酸氫鈣的副好產品，主要是重復使用調試復混肥的主要原料，也可之間灌根于農耕地。白肥施入土體后，夠滿足園藝飼料作物中未來成長發育需求，為園藝飼料作物的中未來成長發育能提供營養金屬原素；與重鈣和過磷酸鈣差距，含水率含氧量低，更易復混肥工作保持；小粒細，從而提高復混肥外在高質量。有機磷肥級磷酸氫鈣溶水土體中，保持多樣輕微金屬原素，用于為各種各樣輕微金屬原素的補足。 Fertilizer-grade calcium hydrogen phosphate, commonly known as white phosphate fertilizer or white fertilizer, is a by-product of the production of feed-grade calcium hydrogen phosphate. It is mainly used as raw material for compounding fertilizer, and can also be directly applied to farmland. When white fertilizer is applied to soil, it can meet the needs of early crop growth and provide nutrients for the middle and late crop growth. Compared with heavy calcium and superphosphate, it has low water content and is easy to control the production of compound fertilizer. It has fine particles and improves the appearance quality of compound fertilizer. Fertilizer-grade calcium hydrogen phosphate dissolves in the soil and releases many trace elements, which can be used as a supplement to various trace elements.
