The Role Of Bio-organic Fertilizer

Jan 05, 2018

Microbial fertilizer and bio-organic fertilizer, in addition to rich humic acid, fulvic acid and amino acids, all contain a large number of beneficial microorganisms, it not only can adjust and improve the soil, prevent soil compaction, balance soil pH, Inhibit the spread of malignant bacteria, reduce the occurrence of plant diseases and insect pests, but also with moisture, temperature, the effect of increasing fat. At the same time, the synergistic effect of microbial fertilizer and bio-organic fertilizer on NPK compound fertilizer made it necessary for us to achieve organic (high content of organic matter), inorganic (large, medium and trace elements) Microbial bacteria (Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Bacillus jelly, Trichoderma, photosynthetic bacteria, etc.), the balance of fertilization, nutrition and fertilization.

1, the synergistic effect of nitrogen fertilizer

Most of the nitrogenous fertilizer is mainly ammonium bicarbonate and urea. The ammonium nitrogen is unstable in nature and highly volatile. After being mixed with bio-organic fertilizer, the bio-organic fertilizer has strong functional groups such as carboxyl group and phenolic carboxyl group, and has strong ion exchange capacity and adsorption capacity , Can reduce the loss of ammonium nitrogen. Amide nitrogen fertilizer, nitrogen contained by the urease secretion of urease decomposition into ammonium carbonate after the plants can be absorbed. If the amide nitrogen into the alkaline soil, the decomposition of ammonium bicarbonate will also be caused by the loss of volatile nature, which amide nitrogen utilization is not high one of the reasons. Amide nitrogen combined with bio-organic fertilizer, amide nitrogen has obvious synergies. First, the activity of urease, slowing the decomposition of amido nitrogen, reducing volatilization; the second is with amide nitrogen formation complex, and gradually decomposed to release nitrogen, so that the effectiveness of amide nitrogen to extend the biological bio-organic fertilizer at the same time Activity can promote plant root development and in vivo nitrogen metabolism, and promote nitrogen absorption.

2, the synergistic effect of phosphate fertilizer

Available phosphate fertilizer applied to the soil, soluble phosphorus is easily fixed by the soil, in acidic soil, phosphorus is mainly fixed by free iron and aluminum ions; in alkaline soil, phosphorus is mainly calcium fixation, the results of the conversion of available phosphorus into delayed-release phosphorus Even invalid phosphorus, seasonal phosphorus utilization is only 10-20%. After bio-organic fertilizer was added, the fixation of water-soluble P could be reversed, the delayed and ineffective conversion of available P could be slowed down, and the organic matter dissolved and dissolved increased the moving distance of P in the soil and promoted the absorption of P by the root system.

3, the synergistic effect of potash

Organic matter contains functional groups can absorb potassium ion storage, both to prevent its loss of water in the soil and leaching soil, but also to prevent the fixation of clay in the clay. Some parts of organic matter such as humic acid humic acid low-humic acid, potassium silicate, potassium feldspar and other minerals have a dissolution effect, you can make it slowly decomposition, increase the release of potassium and improve the content of available potassium.

 4, the synergies of fertilizer

There is a considerable amount of trace element reserves in the soil, but due to the antagonism of the elements and the fixing effect of the soil and the chemical combination of certain acid radicals, too few effective parts can be absorbed by the plants. Organic matter and insoluble trace elements can occur complexation reaction to generate soluble, easily absorbed by the organic acid trace element complexes, is conducive to the absorption of plant roots and promote plant absorption of trace elements from the roots to the aerial part Transfer, from some leaves to other leaves spread.
