How is the humic acid effect on dragon fruit
As we know, humic acid is good for dragon fruit with humic acid fertilizer. So how good is humic acid fertilizer? How can it be better? It is shown that the application of humic acid fertilizer and organic-inorganic compound fertilizer is compared with the application of chemical fertilizer: the yield of general field grain and oil crops increases by about 8% to 20%, and the yield of fruits, vegetables, and cash crops increases by about 15% to 35%. Humic acid fertilizer is called 4 aspects in the industry due to its special effects: slow-release agent of nitrogen fertilizer, synergist of phosphate fertilizer, protective agent of potash fertilizer, and chelating agent of middle and trace elements.
The role of organic fertilizer humic acid is divided into three aspects: physical, chemical and biological:
1. the physical function is mainly manifested in: improving soil structure. Prevent soil cracking and erosion. Increase soil water holding capacity and improve crop resistance to cold. Darken the color of the soil to help absorb solar energy.
2. the chemical action is mainly manifested in: adjusting soil pH. Improve and optimize the absorption of nutrients and water by plants. Increase soil buffer capacity.
Under alkaline conditions, humic fulvic acid is a natural chelating agent (chelates with metal ions to promote its absorption by plants). Rich in organic matter and minerals necessary for plant growth.
Improve the solubility of organic fertilizers and reduce the loss of fertilizers. The nutrients are transformed into a state that can be easily absorbed by plants. strengthen the absorption of nitrogen by plants, reduce the fixation of phosphorus, protect the elements such as nitrogen, phosphorus and potassium deep in the soil, store them in the soil, and accelerate the process of nutrient elements entering the plant body, and improve the application effect of inorganic fertilizers.
3. the biological effects are mainly manifested in: stimulating the growth and reproduction of beneficial microorganisms in the soil. Improve the ability of plants to resist natural diseases and pests.
