Do soybeans need to be suppressed after sowing?
Whether soybeans need to be suppressed after sowing depends on soil moisture. Good soil moisture, poor surface soil moisture, dry loose soil, after sowing in order to make close contact with the soil, eliminate gaps, suppress, will not cause soybean upper soil hardening, conducive to seed water absorption and germination, seedling emergence will be accelerated, can be suppressed while sowing. If the soil moisture is large, the surface moisture and soil moisture are good, must not be suppressed after sowing, at this time, if suppressed, including human trampling, it will cause soil hardening on the upper part of the seed, resulting in difficulties in the top soil when soybean seedlings emerge, resulting in lack of seedlings. In order to prevent lax soil sealing after sowing, poor contact between seeds and soil and eliminate gaps, rakes can be used to rake the surface layer after sowing.
