Why do we advocate the use of organic fertilizer in agricultural production? What are the advantages of fertilizer products made by organic fertilizer machine?
(1) Organic fertilizer can improve soil physical and chemical properties and improve soil fertility.
Organic fertilizer contains a large amount of organic matter, generally about 200g / kg. Organic matter is an important material basis of soil fertility. Humus is the main body of soil organic matter, accounting for 50% - 65% of the total soil organic matter. Humus is a kind of complex organic colloid, which can adjust and buffer the pH value of soil, increase the amount of cation exchange in soil, and improve the soil fertility.
(2) Organic fertilizer has comprehensive nutrients and long-lasting effect.
Organic fertilizer is a kind of agricultural fertilizer processed by organic fertilizer equipment system. It not only contains a large number of nutrient elements and trace elements necessary for plants, but also contains rich organic nutrients, such as humic acid, vitamins, auxin, antibiotics and small molecular compounds of organic nitrogen and phosphorus. So organic fertilizer is the most comprehensive fertilizer. After the organic matter is processed into granules by the organic fertilizer granulator, nutrients are released slowly in the soil. In addition, the amount of organic fertilizer allowed to change a large range, generally will not harm the growth of crops. The application of organic fertilizer not only increases the production of crops in the current season, but generally if the effect is still visible after the year, the fertilizer effect is slow and lasting.
(3) Organic fertilizer promotes soil microbial activities.
Soil microorganisms play an important role in the conversion of organic matter and are one of the important indicators to measure the level of soil fertility. For example, the mineralization process of organic matter in the soil, the effective process of organic nitrogen and phosphorus in the soil, and the biological nitrogen fixation process of legumes are all related to the action of soil microorganisms. Therefore, the application of organic fertilizers on the one hand increases the number and population of beneficial microorganisms in the soil, and on the other hand provides good environmental conditions for soil microbial activities and significantly enhances soil microbial activities.
