Potassium fertilizer should be applied first to the potassium-deficient soil, and the soil potassium supply determines the effect of potassium fertilizer application. In practice, according to the soil potassium supply capacity, the potassium fertilizer should be preferentially applied to the soil with low available potassium content, slow-acting potassium storage, and slow release of soil, generally using rice and wheat as the planting target, and its quick-acting effect. potassium content of potassium effective at 40-80ppm (K2O). Potash should be applied preferentially to soils with sufficient phosphorus and nitrogen levels and low yield levels. The coarse texture of sand for low power potash, potassium easily leached, the administration should be considered the priority potassium fertilizer. The potassium content and potassium absorption capacity of various crops are different. For some potassium-producing crops such as tobacco, potato, sugar beet, sugar cane, banana, etc., potassium fertilizer can be applied to increase the yield while improving the quality. For the legume green with a large increase in yield, it is also possible to apply more potassium to increase nitrogen. Potassium fertilizer application should also be paid to high-yield dwarf varieties and hybrid rice that require a large amount of potassium.
