The principle of humic acid fertilizer to improve soil

Humic acid is widely found in peat and lignite. Peat is an organic ore body formed by the long-term biological and physical chemical effects of plant residues. Humic acid is a black or brown colloidal substance is a large class of polycyclic fused ring organic compounds, these substances have a good effect on enhancing soil fertility and improving soil structure.

First, enhance fertility

1. Reducing the fixation of soluble phosphorus in soil increases the utilization rate of phosphate fertilizer and promotes the activation of trace elements in soil. Usually, calcium phosphate in soil is hardly soluble in water, and the hydrogen phosphate formed after humic acid reaction is dissolved in water can be dissolved. Crop absorption.

2. Humic acid can form complexes with trace elements such as iron, aluminum, copper, magnesium, zinc, etc., which exist in the form of some refractory salts, and are dissolved in water and absorbed by crops.

Second, improve soil structure

1, to promote the formation of soil particles. Organic manure can be slowly transformed into humic acid by microorganisms. Frequent application of the golden manure microbial fertilizer will accelerate the conversion process.

2. It is conducive to the regulation of water, fertilizer, gas and heat in the soil. The optimization of soil structure is conducive to the soil has a good permeability, improve soil water, fertilizer, insulation, permeability. When humic acid and microorganisms act to release energy, it is beneficial to the cold resistance of the crop in early spring or late autumn.

3, transformation of poor soil and saline land. The acidity of humic acid and the alkaline neutralization of the saline-alkali soil can adjust the PH in the soil to achieve the effect of salinization.

4, to promote soil microbial activities. After application of humic acid fertilizer in soil, the activity of nitrogen-fixing bacteria has been strengthened, which has enriched soil nutrients and improved the nutrient conditions of crop roots.

Humic acid is one of the most efficient fertilizers in agriculture because it can improve soil, enhance soil fertility and increase crop resistance. Details can be consulted: Beijing Huaxia Kangyuan Technology Co., Ltd. Tel Free Hotline Taobao buy biological fertilizer Click
