If the soil appears green moss, red frost, white frost phenomenon, must be vigilant!

What are the three aspects of soil deterioration?

The first point: soil compaction

I believe you all have some experience. When you go to our fields, you will find the ground hardened and cracked.

Many fruits and vegetables grow roots on the surface, which is not a good thing, not to say because fat is good, good rooting.If the soil is loose, the roots will grow down, underneath rather than above the ground. This is soil compaction.Ten years ago, when we finished ploughing, we put our foot on it and it sank so deep that it reached our knees. Now, it’s about 10 centimeters.What does this show? Our arable layer has moved up, but the arable layer below is as hard as cement, and even our sharp shovels are difficult to shovel down. If our crop roots want to be set down, it is difficult for us to imagine.The soil is stiff, the root system can not go in, then za think, the growth of fruits and vegetables will be strong?

Second: soil acid-base imbalance

Technically: pH.I don’t think you know the pH, it’s not very clear.So, for example, in our fields, you’ll often find a lot of green moss growing on the surface.

Like long moss on the earth wall after rain, this is green moss, after long green moss will grow red moss, serious when the surface of a layer of red frost.After that, the soil also grows a layer of hoar frost, and this hoar frost is like a saline-alkali soil, which is actually like a kind of salt, and this is a serious acid-base imbalance in the soil, too acidic or too alkaline, and in this case, it’s also very bad for crops to grow.

Third: too much salt

In many cases, after planting crops, our crops grow very well in the early stage, but not for a long time, the leaves turn yellow, the plants grow short, the leaf edges gradually lose green, and then dry up, which means too much salt.Do you think it is disease, lack of fertilizer, or drought, watering, medicine, etc., these a series of measures are taken after the effect is not obvious, what is the reason?That it is not water, not drought, not lack of fertilizer, but the soil salt caused by too high.

f there are green moss, red moss and salt frost on the soil surface, and the growth of plants is weak and yellow, it indicates that our soil has deteriorated and soil fertility has been in short supply. In this case, we must pay attention to it and take measures to improve the soil.

A brief description of the causes of soil deterioration

Soil compaction, acid-base imbalance, excessive salt, these problems are basically due to the past we used a large amount of fertilizer, the pursuit of yield yield yield, brutal demand and brutal give, ignored the application of organic fertilizer, ignored the conservation of the land caused by.The soil fertility has declined, the content of soil organic matter has decreased, and the activity of aerobic microorganisms has decreased, and the whole soil environment has deteriorated.Crops cannot grow normally on degraded soil.
