Nitro humic acid sales raw materials
Nitro humic acid
Nitro humic acid is obtained by heating and refluxing for two hours with a mass ratio of 10% nitric acid and humic acid powder at a mass ratio of 3:1. The solution is acidic, so it is soluble in alkaline solutions. It is a highly effective soil amendment, plant growth promoter, fertilizer efficiency synergist and drilling fluid stabilizer.

Effect on soil
Increase soil organic matter and improve soil structure, so to a large extent promote the buffering capacity of the soil. In barren sandy soil, humic acid can maximize the fixation of easily lost water and nutrient elements and then convert it into a form that is easily absorbed by plants; humic acid in clay can help form a granular structure to increase its water retention capacity and air permeability.
Regulate soil acid-base and improve salinity, fix nitrogen, release phosphorus in the soil, promote potassium, calcium, magnesium and sulfur absorption and chelate trace elements to increase soil fertility. The optimum pH range for most plants is between 5.5 and 7.0. Humic acid can balance the pH of the soil, so that the pH of the soil is suitable for plant growth. Humic acid can stabilize nitrogen to a large extent and release slowly, can liberate the phosphorus fixed in the soil by Al3+ and Fe3+, and can chelate trace elements to promote their absorption and utilization by plants, greatly improving soil fertility.
Create a good living environment for beneficial microbial flora, while inhibiting harmful bacteria. Humic acid can directly improve the soil structure to create a good living environment for microorganisms. At the same time, these microorganisms counteract the improvement of the soil structure. At the same time, it promotes the active reproduction of beneficial fungi and produces different kinds of biological enzymes, which in turn help establish the soft structure of the soil and improve the combination. Capacity and water-holding capacity of macro-element and trace element, known as natural drought-resistant agent
Effect on seeds
It promotes seed germination and is called natural rooting powder, so it has a good effect on soaking and transplanting. Humic acid can promote seed germination in a short period of time, which is called natural rooting powder, especially for those crops with low survival rate.
Effect on crop body
Greatly increase plant resistance to adversity, reduce the impact of plant diseases and insect disasters and drought and flood disasters on crops. Humic acid can regulate leaf stomata opening and reduce water transpiration. It can mobilize plants to absorb potassium ions, promote metabolism, promote respiration, photosynthesis, and activate plant enzymes, which can improve crop drought resistance and save water. The ability can be increased by 30%, and the ability of plants to resist drought, cold, and disease and insect pests can be improved.
Effect on fruit
Promote the growth of chlorophyll, and then help photosynthesis to increase the accumulation of sugar, fat and amino acids in plants, promote the growth of crop roots and tubers, increase yield, and improve taste. Humic acid can enhance cell growth and help promote photosynthesis, thereby increasing the sugar and vitamin content of crop fruits. At the same time, humic acid can chelate heavy metals in the soil to prevent them from being absorbed by crops, and its yield and quality will also be greatly improved. improve.
Usage and dosage of nitrohumic acid
Field crops, 50 kilograms per mu, used in conjunction with nitrogen, phosphorus and potassium fertilizers. The amount per acre with particularly poor soil conditions can be doubled.
Greenhouse crops, 70-100 kg per mu, used in conjunction with nitrogen, phosphorus and potassium fertilizers.
It can be used as top dressing, basal fertilizer, strip application, spreading application, and hole application;
It is suitable for crops such as fruit trees, tea, citrus, grapes, strawberries, various trees, flowering trees, flowers, melons, vegetables, rice and so on.
