Humic Acid Rely On Acid To Conditioning

Sep 29, 2017

If the soil is only small sand and water, then the sand is easy to disintegrate. Humic acid is the adhesive that does not disintegrate sand. If water is injected into the sand, Humic Acid either the temperature rises, the water is quickly evaporated; or the water will quickly seep. Humic Acid However, if humic acid is added to sand and water, the evaporation of water is reduced on the one hand and on the other hand reduces the loss of moisture, especially water molecules that are deeply compatible with humic acid. If the same amount of sand and humic acid mixture, Humic Acid the mixture can not only absorb more water, and water is not easy to lose. Humic acid can make the soil to form a certain support force, support crop growth. So, humic acid is the soil water retaining agent.

Humic acid has a strong chelating ability to chelate almost all the nutrients needed for plant growth. For example, there are many carbonate ions in the soil. Calcium ions required for plant growth are easily attracted by carbonate ions The formation of calcium carbonate, but if there is a humic acid situation is not the same, humic acid will be firmly locked calcium ions to prevent it and carbonate ions in contact, so calcium ions will not be fixed, Humic Acid free calcium ions Will be plant absorption, increase the calcium needed for plant growth. Similarly, there are other nutrients, such as magnesium zinc.

In recent years, excessive use of farmland fertilizer, soil is not acidification is salinization. Acid to rely on alkali to neutralize, alkali to rely on acid to conditioning. In chemical experiments, there is a class of substances called "pH buffer", the buffer both the nature of the acid, Humic Acid and the nature of the base. When the acid added to the buffer, the buffer to play their own alkaline, and the impact of acid, so that the degree of acidification becomes very slow. Humic acid is such a buffer. In fact, humic acid substances in the acidic soil has a good performance, the key is that it can chelate toxic aluminum ions. Experimental data show that acidic soil aluminum content of excess, humic acid can be wrapped in aluminum ions, so that aluminum and plant contact, the same reason there are heavy metals such as lead and cadmium, humic acid so the unique nature of it Become a soil antidote.

If we only improve the saline soil, direct application of humic acid raw material powder can be, but must be free raw materials containing humic acid Caixing, Humic Acid with high calcium and magnesium humic acid coal, the role is not large;

If we want to use fertilizer, according to different periods, the use of humic acid salts, such as humic acid potassium or ammonium humate, or the choice of fulvic acid products;

If the crop economy is relatively high value,Humic Acid we can choose better absorption of fulvic acid products, such as fruits and vegetables in the period of fruit selection of potassium fulvate.
