Why is there capillary phenomenon in winter ploughing?

There are many examples of capillary phenomena in nature and daily life.

The catheter in the plant stem is a very fine capillary in the plant, which can absorb the water in the soil; The seam in the middle of the pen tip is also equivalent to capillary. Brick absorbs water, towel absorbs sweat and chalk absorbs ink, which are all common capillary phenomena.

There are many tiny pores in these objects, which act as capillaries.

In agriculture, when drip irrigation is applied to crops, capillary action is also used to make water drip.

Capillary phenomenon is harmful in some cases.

For example, when building a house, there are many fine capillaries in the compacted foundation, which will absorb water from the soil and make the room moist.

When building a house, lay linoleum on the foundation to prevent moisture caused by capillary phenomenon.

The phenomenon that water rises along the capillary has a great influence on agricultural production.

There are many capillaries in the soil, and underground water often rises to the ground along these capillaries.

If you want to preserve groundwater, you should hoe the soil on the ground and destroy the capillaries on the surface of the soil to reduce the evaporation of water.
