Humic acid fertilizer is the nemesis of soil disease

Humic acid fertilizer, the nemesis of "soil disease"?

"Soil disease" refers to the unhealthy soil itself causing crops to fail to grow normally; "soil-borne disease" is a disease that occurs when various pathogenic bacteria live or parasitize in the soil and spread to crops through the soil. Because "soil diseases" are invisible, intangible, and insane, they are often overlooked, and "soil diseases" are also the cause of occurrence and aggravation of "soil-borne diseases".

"Soil disease" performance: The crops are weak in stress resistance, the root system is not developed or even rot, the plants are short or unable to grow normally, small leaves, yellow leaves, early deciduous, flower and fruitless and fruit-dropping often occur, the fruit is deformed or loses the original good flavor of the fruit, or even Unsafe food and so on.

Causes of "soil disease":

⒈Long-term lack of deep ploughing causes the soil tillage layer to become shallow, and the plough layer soil is severely compacted;

⒉Blind use of large quantities of chemical fertilizers causes fertilizer damage and soil nutrient ratio imbalance;

⒊Predatory nutrient management leads to a serious lack of medium and micronutrient elements in the soil;

⒋Soil pollution with chemical fertilizers, pesticides and heavy metals as the main pollution sources;

⒌Extensive use of chemical fertilizers causes soil acidification and secondary soil salinization;

⒍Long-term non-application of organic fertilizers leads to lack of soil organic matter, and soil syndrome in facility agriculture caused by blind management.

Prevention and treatment of "soil diseases"

⒈ Deep ploughing and deep loosening keep the soil tillage layer above 20 cm, thereby improving the soil's ability to retain water and fertilizer and resist natural disasters.

⒉ Scientifically balanced fertilization to prevent problems such as imbalance of nutrient ratio, soil acidification, secondary salinization and soil pollution.

⒊ Control heavy metal-containing, toxic and harmful substances such as high-residue pesticides and industrial waste from entering farmland.

⒋ Promote the direct return of crop stalks to the field to increase the soil organic matter content.

⒌ Increase the application of humic acid and fulvic acid fertilizers and soil conditioners to improve soil structure, enhance soil fertility, inactivate soil heavy metals, and activate soil microorganisms.

Note!!!When improving the soil that has deteriorated, we need to improve our crops in a targeted manner, according to the most suitable pH and salt tolerance of different crops.

Humic acid fertilizer is the nemesis of soil disease

The crops we grow can grow normally within a wide range of pH values, but various plants have their own suitable pH values. When the soil pH value exceeds the optimum range, as the pH value increases or decreases, plant growth will be hindered, and growth will be slower. Most plants have difficulty growing when the pH value is greater than 9.0 or less than 2.5 .

Plants grown in healthy soil are more resistant to disease than plants grown in poor or unbalanced soil. The characteristics of healthy soil refer to a soil condition rich in humus. With it, plants will grow fast, stable and efficient; it also means high yield, high quality, disease resistance, etc.

Potassium humic acid is an important component of humus and is the original substance of soil. Studies have shown that humic acid forms a complex colloidal structure by itself or by interacting with some inorganic components of the soil. These different components are held together by surface tension. This structural system can adapt to changes in water effects and electrolyte reaction conditions. At the same time, a large number of microbial activities also occur in the soil. Therefore, humic acid fertilizers play an important role in eradicating "soil diseases" and preventing and controlling "soil-borne diseases", and people are paying more and more attention.
