The soybeans have been sown, but the old farmer is worried that it will affect the emergence of beans

After soybean sowing, it has been raining all the time. Can it sprout? Don't worry too much, emergence is still possible, but if it rains heavily or continuously for a long time, the emergence rate and uniformity of emergence will be greatly reduced. In fact, this is similar to the principle of watering after sowing, which will have a certain impact on the emergence of seedlings after sowing. Let's talk about it in detail below.

Due to continuous rain, it will inevitably lead to a substantial increase in soil density on the soil surface, that is, surface soil hardening, so that it is easier to form surface runoff in rainy days, so as to remove rainwater from farmland without forming waterlogging disaster on farmland. However, a big problem is that after the surface soil hardens, the increase in density brings difficulties to soybean emergence.

However, there may be some areas where soil loss may cause soil coverage in some areas to be too deep, resulting in soybean seedlings unable to emerge because they cannot break through the soil layer, which is naturally a major problem with rain.

In addition, while the surface runoff caused by the continuous rain in farmland leads to soil erosion in farmland, many soybean seeds will be washed out due to the influence of surface water flow, and even some soybean seeds may be exposed due to water flow. In this way, after the weather clears up later, it will not be able to absorb soil moisture, and naturally it will not be able to sprout, even if it can germinate later. It may also die because the roots are too shallow to absorb enough water.

In view of the above situation, the farmland can be loosened after rain, which can make the farmland soil soft, increase the permeability of the soil to provide more sufficient oxygen for seed germination, and clean up weeds in the farmland through deep loosening.
