1. Product Introduction
Our company's nitrohumic acid granular are derived from selected self-owned weathered coal mines in Fukang area, Xinjiang, and contain a variety of active functional groups. Nitrohumic acid granular have high hardness, which can quickly adjust acid, inhibit urease, and improve nitrogen utilization. Improve the structure of soil aggregates, increase cation exchange, slow-release nutrients, non-toxic by-products, environmental protection and dust-free. The preparation process is to crush the raw coal and sieve it, add nitric acid solution to react, spray it into the raw coal powder in layers during the addition process, seal the reaction, fully mature, dehydrate the stock solution, steam dry the water, and make the dehydrated raw powder into granulartion. This product is black particles, less dust, easy to apply and store, suitable for large-scale mechanical sowing or fertilization, long-term slow release.

3. Use
Nitrohumic acid can significantly improve fertilizer efficiency, improve soil, increase yield and quality, promote roots and seedlings, and increase yield resistance when used in agriculture.
(1) Soil conditioner: Nitrohumic acid can improve soil structure, increase soil organic matter content, and improve soil water and fertilizer retention capacity. Its acidic functional groups neutralize alkaline soils and regulate pH.
(2) Fertilizer synergist: Used in combination with nitrogen, phosphorus, and potassium fertilizers, it can improve fertilizer utilization and reduce nutrient loss. Nitrohumic acid can also promote crop root development and enhance stress resistance. Base fertilizer/top dressing: 750-1500 kg/ha, mixed with compound fertilizer or organic fertilizer and then applied in strips, holes or spreading; The addition of compound fertilizer accounts for 5-10% of the total mass of compound fertilizer, and is incorporated into the fertilizer formula as a functional synergistic ingredient.
(3) Plant Growth Regulator: Its active group stimulates plant growth, promotes root absorption of nutrients, and improves crop yield and quality.
Notes:
Avoid applying it at the same time as high-calcium products to reduce the amount of ion exchange of the product and affect the effect.
Store in a dry, cool, and dark place to prevent moisture absorption and agglomeration.
