Humic acid is a product of soil organic matter humification, and peat (peat), lignite, and weathered coal contain a large amount of humic acid. The humic acid
organic fertilizer manufacturing process is a process of adding a certain amount of nitrogen, phosphorus, potassium or some trace elements to the organic fertilizer by using humic acid as the main raw material. Humic acid organic fertilizer contains a large amount of organic matter and a large amount of effective nutrients.
Since humic acid has the functions of increasing soil organic matter and inorganic nutrient content, increasing the effective utilization rate of chemical fertilizers, increasing crop yield, improving crop quality, etc., organic fertilizer production line humic acid produces organic fertilizer and compound fertilizer (complex fertilizer) as a kind of new fertilizers are becoming the development direction of ecological agricultural fertilizers in the 21st century. Here we mainly discuss the application of humic acid in the fertilizer in agriculture.
1. Using humic acid, it can change the physical and chemical properties of soil with high salt content, excessive alkalinity, high soil particle dispersion and poor soil structure, promote the formation of soil aggregates, and make it into a good state, thus plant root growth. Development creates good conditions.
2. The application of humic acid can loosen the soil layer, destroy the accumulation of salt, reduce the salt content of the topsoil, play a role of salt separation, increase the emergence rate, reduce weak seedlings, dead seedlings, and make plants grow healthily.
The
new organic type organic fertilizer granulator is also called wet organic fertilizer granulator. It is used to complete the granulation process in the wet state with powdery materials, especially for chicken manure, pig manure, cow dung, mushroom residue, straw, humic acid, and sugar cane. The slag has special effects for granulation. The operating conditions for granulation and subsequent processes (such as drying, packaging, etc.) are greatly improved. Usually the dust reduction rate is over 90%. Granulation can avoid the phenomenon of agglomeration and bridging which are easy to occur in powder products, and avoid secondary pollution caused by the use of powder, which greatly improves the physical properties of the product. The fermented raw material can be granulated at a moisture content of 40%, thereby ensuring the quality of organic fertilizer products.
