How to water the ridge?

It is no secret that our harvest depends on the proper watering of plants. Improper watering can not bring any benefit, but, on the contrary, leads to drying out of the soil, not to mention its other negative sides. Therefore, let's find out how to water the ridge?

Therefore, let's find out how to water the ridge?

When watering, the ridges very often give a large amount of water at once, and you can see that the soil surface floats heavily, semi-liquid mud forms that does not allow water to penetrate the soil, and as soon as the soil surface dries out, a dense crust forms on it that promotes quick drying. large strata of soil.

Such a swimming of the soil during watering is due to the fact that the air in the capillaries of the dry soil, when it is poured at once with a large amount of water, is pulled out of the soil and destroys its lumps, turning them into dust. Dust first contributes to the erosion of the soil, and then forms a crust and prevents the soil from soaking in water. All this is very easy to prevent if you first slightly sprinkle the surface of the soil with water, so that all the capillaries suck in water and the air comes out gradually. At the same time, the water will penetrate well into the depth, without flowing into the grooves and will last longer in the soil.

Now we see that in order for the watering to give the best results, you should first sprinkle the soil a little and then pour it abundantly with water. The soil devoid of capillary air, does not swim, well-soaked with water and retains it in sufficient quantity. In order to save water in the soil even after proper watering of the beds (with preliminary sprinkling), it is necessary to loosen the surface of the ridge as soon as possible in order to minimize the flow of water through the capillaries to the soil surface and its drying. Then the water will remain in the soil for a long time, will be consumed only by plants and will not require frequent watering. Vegetable growers call this method dry watering, giving it greater importance than frequent and weak watering.

Hence the basic rule of irrigation: to give abundant, at least rare irrigation, with the specified precautions and then carry out surface loosening, maintaining the top layer of soil in a state of destroyed capillaries.

Of course, the situation is somewhat different with seed germination, before germination. It is necessary to maintain the moisture of the surface layer of the soil where the seeds are located, and to prevent it from drying out. Therefore, as long as the seeds do not come up, frequent light irrigations are sometimes helpful. But even here it is much safer to rely on the nutrition of seeds from below, due to its reserves in the soil, ensuring its supply to the seeds and protecting it from evaporation by special techniques.

For this, it is necessary that the seeds, when sown, be placed on compacted soil and covered with loose soil (which does not allow water to evaporate). This is achieved by the fact that, having made a groove for sowing seeds, the bottom of it is somewhat compacted and when sown, the seeds are slightly pressed into the compacted soil. The seeds fall asleep very loosely, in order to give air access to them and to protect the water attracted by soil compaction from evaporation.

This rule to place the seeds when sowing on the border between loose and dense soil layer plays a big role in field cultivation. And all these skills how to properly water the ridge, clearly indicate how knowledge of elementary physical phenomena allows them to be used to good advantage, and shows what mistakes can occur when they are ignored.
