What is the correct way to fertilize soybeans?Urea 2 30 kg, superphosphate 3 40 kg, potassium sulfate 2 30 kg
Fertilization time. The fertilization time of soybeans can be summarized as "one base and three chases". Before sowing, basal fertilizer is applied to the soil to ensure the nutrient requirements of the soybeans throughout the growth process. During the growth period of soybean, according to the growth of soybean and the law of fertilizer demand, nitrogen, phosphorus, potassium and other fertilizers should be appropriately applied to promote the growth and development of soybean.
Type of fertilization. The types of soybean fertilization mainly include organic fertilizers and chemical fertilizers. Organic fertilizers mainly include human and animal manure, manure, compost, etc., which can improve soil structure and improve soil water and fertilizer retention capacity. Chemical fertilizers include nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, etc., which can meet the nutrient needs of soybeans during the growth process.
Amount of fertilizer. The amount of soybean fertilizer should be determined according to soil fertility, variety characteristics, growth environment and other factors. Generally speaking, apply 1000-2000 kg of organic fertilizer per mu, the correct fertilization method for soybeansUrea 2 30 kg, superphosphate 3 40 kg, potassium sulfate 2 30 kgIn the flowering and podding stage, nitrogen fertilizer and potassium fertilizer should be appropriately applied to promote the growth and development of soybean.
Fertilization method. There are two main fertilization methods for soybeans: spreading and stripping. Spreading is to spread fertilizer evenly on the surface of the soil, which is suitable for the application of organic fertilizer and chemical fertilizer. Strip application is the application of chemical fertilizer in the sowing furrow or between the rows, which is conducive to improving the utilization rate of fertilizer and reducing environmental pollution.
In conclusion, in the process of soybean planting, the correct fertilization method is of great significance to improve the yield and quality of soybean. Farmers should pay attention to choosing the right fertilizer type and amount when fertilizing, and adopt appropriate fertilization methods according to the actual situation to provide sufficient nutrients for the growth of soybeans.
