Pesticide Free Cert Nitrohumic Acid Powder Insoluble Custom Formula

Product Specification

1. Product Introduction

Our company's nitrohumic acid powder comes from selected self-owned weathered coal mines in Fukang area, Xinjiang, containing nitro (-NO₂), carboxyl (-COOH), phenol hydroxyl (-OH) and other active functional groups, with strong cation exchange ability and high complexation ability. low molecular weight and higher absorption efficiency than ordinary humic acid; It has the functions of promoting roots, resisting drought, improving nutrient utilization (more than 20% increase in nitrogen, phosphorus and potassium), adjusting soil pH, and improving aggregate structure, and has a wide range of uses. The preparation process is to first crush the raw coal, sift it for later use, add nitric acid reaction, fully react, filter, remove the unreacted residue and dry, and dehydrate and sieve to prepare; The product is black powder, working block; It is weakly acidic, has strong complexing ability, has redox properties, can participate in soil redox reactions, has ion exchangeability, and has high cation exchange capacity.

3. Use

Regulate soil microecology, and the pore structure is higher; Improve and repair compacted/saline-alkali soil, promote the formation of aggregate structure, and enhance the ability to retain water and fertilizer. It has a low molecular weight and higher absorption efficiency than ordinary humic acid.

(1) Soil improvement: increase the aggregate structure, increase soil porosity, reduce bulk density, and alleviate compaction and salinization; Adjust the pH value (can be used as a rice seedling acid regulator, the pH is reduced from 8 to 6-6.5).

(2) Fertilizer efficiency: inhibit urease activity and reduce nitrogen volatilization by 40%; Complexing phosphorus and potassium reduces the fixation rate by 50% and improves the utilization rate by more than 20%.

(3) Fertilizer efficiency: inhibit urease activity and reduce nitrogen volatilization by 40%; Complexing phosphorus and potassium reduces the fixation rate by 50% and improves the utilization rate by more than 20%.

(4) Root resistance: stimulate root growth, increase the number of root hairs, improve nutrient absorption area, and enhance drought, disease and saline-alkali resistance; In the pot experiment, the fresh weight of crops increased by 3-10%, the vitamin C content increased by 6-44%, and the chlorophyll content (SPAD value) was increased, and the yield and quality were finally improved.

(5) Trace element activation: chelate insoluble elements such as iron and zinc to form an absorbable state and solve the "deficiency syndrome".

(6) Microbial activation: promote the proliferation of nitrogen-fixing bacteria and actinomycetes by more than 30%, accelerate the decomposition of organic matter, and improve soil fertility.
