What to do if the soil becomes compacted when growing soybeans? Is soybean suitable for dry soil?

Soybeans contain high-quality plant protein. They can not only be used to make oil, but also processed into various side dishes. Soybeans are highly adaptable and are grown all over the country. Soybean roots are not well developed, so they have requirements for soil and soil quality. The following is information on soybean cultivation compiled by this website. Let's learn about it together!

What to do if the soil becomes compacted when planting soybeans

Soil compaction will affect root respiration, and the root absorption of nutrients and water will be greatly reduced. It will also affect the activity of probiotics, and soybeans will easily have pods but no grains.

Prevention and control methods: Before sowing soybeans, the land must be carefully prepared and the soil must be carefully cultivated. Loose soil is conducive to the development of roots, and well-developed roots will increase the drought resistance of soybeans.

Are soybeans suitable for dry soil?

The root system of soybeans is not well developed and is neither drought-tolerant nor waterlogged. It is best to keep the soil moisture content at around 75% during the flowering and pod formation period. Too dry soil will cause the roots of soybeans to lose water, the plants will wilt easily, the photosynthesis of the leaves will also decrease, the synthesis of organic matter will decrease, and it will be unfavorable for the expansion of the fruit. At the same time, if the soil is waterlogged or the weather is continuously rainy, it will affect the respiration of the root system, the roots may rot, and the absorption of nutrients by the roots will be reduced, resulting in soybean pods but no fruit.

If the soil is too dry, you must water the soil. On rainy days, you must take drainage measures to prevent water from accumulating in the ground. If the soil is too wet, you can sprinkle wood ash on the ground to reduce humidity. Wood ash can not only prevent insect pests, but also is a very good organic fertilizer, which is conducive to increasing soybean production and income.

Does soybean need crop rotation?

It is definitely necessary. Reasonable crop rotation can reduce the occurrence of pests and diseases. When soybeans are planted continuously, the pests and diseases left by the previous batch of soybeans and the accumulated pathogens in the soil will make the newly planted soybeans very susceptible to pests and diseases. When planting soybeans, a rotation of more than three years should be implemented, such as wheat-corn-soybean, wheat-wheat-soybean, wheat-millet-soybean-wheat, etc. Reasonable crop rotation can reduce the probability of soil-borne diseases.

China has cultivated soybeans since ancient times, with a history of 5,000 years. It is widely cultivated throughout China and is produced in Northeast China, North China, Shaanxi, Sichuan and the lower reaches of the Yangtze River. It is cultivated more in the Yangtze River Basin and Southwest China, and the quality of soybeans in Northeast China is the best. It was introduced to the United States in 1804; in the middle of the 20th century, it became an important crop in the southern and Midwestern United States. Soybeans cultivated in various countries around the world are directly or indirectly spread from China. Due to its high nutritional value, it is called "the king of beans", "meat in the field", "green milk", etc. It is the most respected food by nutritionists among hundreds of natural foods.
