Characteristics and functions of common fertilizers
In sandy soil, all phosphate fertilizer should be used as base fertilizer, half of nitrogen fertilizer should be used as base fertilizer, and the other half should be topdressing by stages in the process of growth and development, and then the amount of water should not be too large to avoid fertilizer leakage after flood irrigation. In clayey soil, under the condition of water irrigation, phosphate fertilizer and nitrogen fertilizer of 2 to 3 can be used as base fertilizer, nitrogen fertilizer of 1 to 3 can be applied by stages, and none.

The proportion of nitrogen, phosphorus and potassium applied to potatoes should be appropriate.
The demand for nitrogen, phosphorus and potassium in potato is equally important. In the process of yield formation, nitrogen supply is the basis to ensure the formation of sufficient green leaf area for photosynthesis; phosphorus supply is also indispensable for tuber formation and starch accumulation; on the basis of sufficient nitrogen and phosphorus, potassium supply is necessary for carbohydrate assimilation in the early stage, aboveground to underground tuber transportation and starch accumulation in the later stage. The field test showed that the absorption ratio of nitrogen, phosphorus and potassium in potato was about 1 ∶ 0.5 ∶ 2.5.

Ratio of nitrogen, phosphorus and potassium in Rice Base Fertilizer
The ratio of nitrogen, phosphorus and potassium in rice base fertilizer is 2 to 1. 2. Of course, the land fertility in different areas is different, or the amount of phosphorus, nitrogen and potassium fertilizer should be determined according to the content of phosphorus, potassium and nitrogen in the local soil. In addition, we should pay attention to the method and use when fertilizing rice.

Ratio of nitrogen, phosphorus and potassium in soybean
In the seedling stage of soybean, appropriate edible nitrogen fertilizer makes the plant grow stronger, and it is generally appropriate to apply 7.5 to 10 kg of urea per mu. Spraying 0.2% to 0.3% potassium dihydrogen phosphate solution or calcium superphosphate water root at flowering stage can increase the nitrogen content of grains and significantly increase the yield.

What is the law of fertilizer requirement in each growth stage of rice?
The law of nitrogen absorption: sleeping until sleep is very sensitive to nitrogen nutrition, which is the most important factor to determine the quality of rice. Rice has a high nitrogen concentration in its whole life, which is the nutritional and physiological characteristics needed for high-yield rice. There are two obvious peaks of nitrogen uptake by rice. One is the tillering stage, that is, 2 weeks after transplanting.
