The benefits of humic acid!!!

Current scientific research has shown that soil fertility is largely dependent on the amount of humic acid in the soil. A number of humic acid properties such as CEC, oxygen content, and the ability to retain water are equally important in explaining the high efficacy of humic acid application in increasing fertility and plant growth. ***Importantly, humic acid can combine with metal cations, oxygen, and hydroxide compounds, thus slowly accumulating and releasing them for crop use. Due to these characteristics, humic acid can have three effects: physical, chemical, and ecological.

　　1、Physical properties of humic acid

　　Humic acid can change the structure of soil

　　It can keep the water and nutrients in the sandy land after dissipation, and at the same time, it can make them form fertile soil through decomposition; for cultivation and hard land, it can improve the ventilation and air permeability of the soil, and improve the cultivation conditions.

　　Humic acid can prevent soil breakage and erosion by binding water to the soil surface. Further soften the soil to increase soil permeability and improve soil utilization, increase soil drought resistance, make the soil color darker, more conducive to the absorption of sunlight.

　　2、Chemical advantages

　　HA can change the characteristics of soil fixation (binding).

　　(1), Neutralize the acidity and alkalinity of the soil and regulate the PH value.

　　(2), Improve and optimize the absorption of nutrients and water by crops;.

　　(3) Increase the buffering properties of the soil.

　　(4) In alkaline environment, it can chelate metal cations to enhance the absorption of water by roots.

　　(5), rich in organic matter and minerals needed for plant growth.

　　(6), keep water in the roots of crops can dissolve inorganic fertilizers and thus reduce their leakage.

　　(7) Promote the conversion of (N, P, K) and micronutrients into useful forms for crops.

　　(8) Enhance crop uptake of nitrogen.

　　(9), reduce the reaction of phosphorus with calcium, iron, magnesium, aluminum, and then convert them into forms that can be absorbed by plants and then released, and at the same time, it can significantly improve the utilization efficiency of mineral fertilizers.

　　(10), Release CO2 from calcium carbonate in the soil to promote photosynthesis.

　　(11), can reduce the lack of cations in crops resulting in chlorosis.

　　(12), can reduce the toxic substances in the soil.
