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.
