    Three effects of organic manure with humic acid

    Addtime:2016-10-11

     Humic acid containing organic fertilizer is a kind of humic acid containing a new type of fertilizer, is also a multi-functional organic, inorganic compound fertilizer. Containing humic acid organic fertilizer used as basal fertilizer, fertilizer, topdressing and soaking, dipped in roots, foliar spraying have increased production results.

    In recent years, a large number of research and application of humic acid-containing organic fertilizers has been carried out in various parts of China, indicating the effect of humic acid organic fertilizer on agricultural production. It is a versatile organic, inorganic compound fertilizer, is also a good soil structure improver, and has the effect of stimulating plant growth and promoting nutrient uptake.

    First, improve the soil and improve the role of fertility

    Humic acid organic fertilizer can promote the formation of soil structure, improve the pore conditions; improve the cationic absorption of soil properties, increase soil fertility and fertilizer capacity; enhance the soil buffer system, improve the acid soil; promote soil beneficial microbial activities. Its specific is:

    1, is conducive to soil water, fertilizer, gas, heat regulation. When the soil particle structure is improved, its bulk density decreases, the porosity increases with good permeability. And because the color of humic acid fertilizer is conducive to the absorption of solar heat. When the humic acid fertilizer by the role of microbial decomposition of the release of heat, especially in the early spring season, when the crop just unearthed to improve the ground temperature and play the role of anti-chill.

    2, to promote the formation of soil aggregates. Ammonium humic acid can promote the formation of soil aggregates, the application of organic fertilizer to the soil can also improve the soil structure, which is mainly through the soil microbial slow conversion, if the regular application of humic acid fertilizer will accelerate this transformation process.

    3, to promote soil microbial activity. After the application of humic acid fertilizers in the soil, the activities of microorganisms in the soil have increased, especially in the soil, the nitrogen content of the soil is significantly increased, the nitrate content is obviously increased, and the nitrogen nutrition of the soil is improved. Nutritional conditions. The following are the same as the "

    4, the transformation of poor soil and saline land. Long-term adherence to the application of humic acid fertilizers will fundamentally transform the barren soil into fertile land. In the south the use of humic acid fertilizer improved "acid, barren, plate, dry" red soil, also made outstanding results. As the acidity of humic acid can be neutralized with alkaline saline soil, so humic acid can adjust the soil pH (pH) to achieve the effect of salt. The following are the same as the "

    5, humic acid can form some complex with trace elements such as iron (Fe), aluminum (Al), copper (Cu), manganese (Mn), zinc (Zn) and the like in the form of insoluble salts, Crop absorption. The traceability of these trace elements in the commercial chemical chelating fertilizer is very expensive. Farmers are reluctant to buy and humic acid can be chewed as a source of cheap natural chelating agents with trace elements so that they are easily absorbed by crops.

    6, to reduce the soil on the fixation of soluble phosphorus to improve the utilization of phosphorus and promote the activation of trace elements in the soil, usually in the soil calcium phosphate [Ca3 (PO4) 2] is difficult to dissolve in water, and the formation of humic acid after the reaction Hydrogen phosphate and dihydrogen phosphate are soluble in water can be absorbed by crops.

    Second, increase crop nutrition and fertilizer synergies

    Humic acid containing organic fertilizer can increase fertilizer efficiency, can eliminate the application of excessive nitrogen fertilizer or improper application of the adverse effects, so that the fertilizer efficiency of inorganic nitrogen fertilizer from the "storm, fierce, short" into "slow, stable, long"; rot The fertilizer itself also contains a certain amount of available nitrogen, phosphorus and delayed nitrogen and phosphorus, which can serve to improve crop nutrition.

    Third, the stimulation of crop growth and development

    Humic acid containing organic fertilizer can make the seeds early germination, improve its emergence rate; promote rooting and improve the ability of root absorption; enhance the development of reproductive organs.
