The main role of bio-organic fertilizer

- Aug 01, 2019-


(1) Improve soil structure

Bio-organic fertilizer is the best soil-improving agent, which can promote the formation of soil aggregate structure and improve the physical properties of soil, mainly to increase non-capillary porosity and increase the size of stable aggregates. While improving the soil structure, the aeration and water permeability of the soil can also be enhanced.

(2) increase soil nutrients

Bio-organic fertilizers contain nutrients necessary for crop growth, and their nutrient characteristics are as follows: first, the organic matter is adsorbed in a large amount, and nutrients are not easily lost; second, the nutrients are complete, easily decomposed, and easily absorbed by crops. The application of bio-organic fertilizer not only supplements soil nutrients, but also activates soil nutrients. The organic acid or some organic groups generated by the decomposition of bio-organic fertilizers are chelated or bound to iron and aluminum, which can reduce the fixation of phosphorus in the soil. The decomposition of bio-organic fertilizers, especially under flooding conditions, can improve the reductive properties of the soil, and make the iron and aluminum in a reduced state and increase the solubility of phosphorus. Bio-organic fertilizers increase the activity of soil microbes, enhance the permeability of carbon dioxide in the soil, regulate the pH value of the soil to some extent, and increase the effectiveness of trace elements such as zinc, manganese and iron in the soil.

(3) Improve the biological activity of the soil

All kinds of bio-organic fertilizers are rich in organic matter, which provides sufficient nutrients and energy for soil microorganisms, accelerates the growth and reproduction of microorganisms, not only increases their quantity, but also increases their activity, mineralization and nutrition in organic matter. The accumulation of elements and the synthesis of humus play an important role. Under the action of microorganisms, organic nutrients are continuously converted into effective nutrients that plants can absorb and utilize, and at the same time, some nutrients fixed in the soil can be released. Microorganisms can decompose phosphorus-containing compounds and release soil-fixed phosphorus. Silicate bacteria can increase the activity of potassium in soils; microorganisms can also fix easily lost nutrients in soil.


(4) Improve crop yield and improve crop quality

The bio-organic fertilizers have the stimulating effects of vitamins, humic acids and hormones produced by microbial decomposition and transformation, which can promote the vigorous growth of crop roots, improve their absorption capacity for nutrients, especially phosphorus and potassium, and enhance the photosynthesis of crops. The root system of the crop is developed, the accumulation of dry matter is increased, the rate of ear formation is increased, the characteristics of the ear are improved, and the yield is increased. Bio-organic fertilizers are comprehensive in nutrients. They contain a variety of inorganic elements and a variety of organic nutrients (such as amino acids, sugars, nucleic acid decomposers, etc.), and also contain a large number of microorganisms and enzymes, which are unmatched by any chemical fertilizer. Sexuality has a special effect on improving the quality of agricultural products and maintaining their nutritional flavor.

(5) Enhance crop stress resistance

Bio-organic fertilizer can improve soil structure, enhance soil water storage and water retention capacity, reduce water evaporation, and improve moisturizing effect, thereby improving crop drought resistance, cold resistance and frost resistance, so that it can be better under harsh climatic conditions. Maintain its inner and appearance qualities. The application of bio-organic fertilizers increases the activity of soil microorganisms and increases the anti-biomass, thereby promoting the robust growth of crops and improving their disease resistance. Bio-organic fertilizers have complete nutrients, and coordinate the supply of macroelements and trace elements during crop growth and development, avoiding the diseases caused by the lack of certain elements in the crops (such as the black spot caused by potassium deficiency in potatoes, and the beet is bad due to zinc deficiency. Heart disease, etc.), thereby improving crop quality.

(6) Improve economic efficiency

Since bio-organic fertilizers significantly increase crop yields, application of bio-organic fertilizers can reduce vegetable yields by reducing fertilizer use by 75%. The improvement of crop quality by bio-organic fertilizers is mainly manifested in the increase of vitamin C and β-carotene and the decrease of nitrate content, especially the taste and appearance quality, so that significant economic benefits can be obtained. Because bio-organic fertilizer also has obvious effects of improving soil and fertilization, improving fertilizer utilization and protecting the environment, it has good social and ecological benefits.
