Is there any other way to increase the content of organic matter in organic fertilizer?

1, increase fermentation raw materials, different raw materials have different organic matter and various nutrients.

2. Formula adjustment of fermented organic fertilizer.

3. Increase cake, biogas residue, crop waste and high-quality poultry manure.

4. increase organic matter.

organic matter

1, fertilizer:

The excrement of various animals is a common organic fertilizer, such as the excrement of poultry, cattle, pigs, sheep and other animals, including solid and liquid. The types and nutrients of excreta are very different from those of animals, and the difference of feed and digestibility is also an important influencing factor. Generally, chicken manure contains more nitrogen, and pig manure usually contains more phosphorus than cow manure. Both solid and liquid (urine and water) in animal excreta can be treated separately, or mixed with absorbing materials (plants or adsorbents) for manure. Taiwan Province Province is moving towards the enterprise management of raising pigs and chickens, and the treatment and utilization of these animal wastes are worthy of attention.

2, plant residue:

Crop residues can be used as fertilizer, compost or left in the ground as organic fertilizer. Although the nutrient content of crop residues is not high, it can mainly improve the soil structure, produce many organic acids when decomposed, and improve the availability of soil nutrients, especially the supply of trace elements.

Compost is the product of accumulation and partial decomposition of animal and plant wastes. Because there are many kinds of materials, even garbage can be composted, it is necessary to have some basic understanding of composting:

The purpose of applying compost is to improve soil organic matter and growth promoter, so as to maintain the position of soil, especially for the physical, chemical and biological aspects of soil.

The decomposition of organic matter is carried out by microorganisms, so the composting environment should be suitable for the conditions of microbial activities, such as sufficient humidity and ventilation. In the production process, it is necessary to go through the steps of stacking and turning over materials, and it is also necessary to provide enough nitrogen for microbial reproduction. In order to get a better start, compost or microbial inoculants can be used to accelerate the formation and decomposition of compost, which can produce high temperature and help to kill germs. Therefore, covering compost to increase temperature is also a useful method.

Adding minerals and other organic matter can accelerate composting, especially adding nitrogen-containing organic matter (bean powder and yeast powder), which is most effective for composting materials with high C/N ratio, and is often applied in the amount of 0. 1 ~ 1%. Calcareous materials can reduce the occurrence of acidity. For example, the common amount of limestone powder is 0.3-0.5%, which contributes to the quality of compost.

Soil animals are often considered to accelerate the decomposition of organic matter, but they are rarely used in practice.

3. Green manure:

Green manure takes whole green plants or stems and roots as direct fertilizers, and there are many kinds of green manure crops, including beans, such as sesbania, hemp, cucurbitaceae, Chinese milk vetch, soybean and other green manure crops; In addition, non-leguminous plants such as rape and radish are also useful. Leguminosae can use rhizobia to fix nitrogen in the air and increase nitrogen sources in the soil. Green manure crops, whether leguminous or non-leguminous, can preserve soil nutrients, absorb soil nutrients into green manure plants, temporarily preserve them, reduce losses, decompose and release nutrients when supplying green manure, and improve the effectiveness of phosphorus and trace elements in decomposition.
