Composting additives
Composting additives
Additives are microorganisms, organic or inorganic substances added to compost to speed up the composting process or improve the quality of compost products
1. Organic fertilizer fermentation fungicide
Organic fertilizer fermentation agent is a kind of microbial active agent that can decompose cellulose and accelerate the decomposition and decay of various organic materials (including crop straw, livestock and poultry manure, household garbage and municipal sludge, etc.).
The previous chapter explained what is microorganism and its role, talking about the compost fermentation of organic materials is carried out by microorganisms, without microorganisms, compost will definitely not ferment, so organic fertilizer fermentation bacteria can also be understood as people from nature specially screened out of the special rotten organic materials of microorganisms. The image is that the microorganisms in the organic fertilizer fermentation agent are specially selected by people, they especially like to eat organic materials, as soon as they touch them, they bite them in large mouths, and at the same time, the nutrients needed by the crop are released, and at the same time some odorous substances are digested into gas and run away, and organic materials such as livestock and poultry manure become odorless and easy to transport and use rotten organic fertilizer.
How to use organic fertilizer fermentation fungicide: put no less than 10 square meters of livestock and poultry manure pile in hard flat land or fermentation shed, use straw and other materials to control humidity in the state of hand grasping into a clump, hand loose and scattered, add 1% (weight ratio) of organic fertilizer fermentation fungicide, manually or mechanically overturned to make organic materials, auxiliary materials and fungi mixed and fermented, the stack height is controlled at 80~100 cm, when the pile temperature reaches 55 °C, the pile is suffocated for three consecutive days to kill pest eggs, and then turn the pile every two days, turn the pile to reconcile and evenly crush, and the fermentation ends after the heap temperature is constant The finished product is rotten organic fertilizer, with a cycle of 15~20 days.
2. Crop straw
When the compost raw material has more water content and low C/N ratio, it will cause poor compost aeration and nutrient imbalance, and it is necessary to add some dry crushed crop straw (straw, wheat straw and corn straw, etc.) to adjust the moisture and nutrients of organic materials to adapt to the better growth of microorganisms in the compost, thereby promoting better and faster decay of compost. Of course, in addition to adding crop straw, you can also add organic substances such as sawdust and bran.
Third, urea
When the ratio of compost raw materials C/N (suitable ratio 25-30:1) is too high, that is, the N content is low (C/N>30:1), because the nitrogen nutrients are too low, the growth of microorganisms will be affected, and the compost fermentation process will naturally be inhibited, therefore, in the composting process, it is necessary to add nitrogen-containing raw materials to adjust the C/N ratio, such as urea, generally add 5 kg of urea per ton of material, of course, you can also add peanut cake, soybean cake, soybean meal powder and other raw materials with high nitrogen content after extracting oil for C/ Regulation of the N ratio.
4. Grass charcoal
Grass charcoal, also known as peat or peat, consists of plant residues that are not completely decomposed and fully humified humus as well as minerals. Grass charcoal is a unique product of swamps, and due to excessive humidity or thin layers of water, a large number of charcoal-forming plant residues cannot be completely decomposed under the action of anaerobic microorganisms, and gradually accumulate and peat, forming peatlands with different thicknesses of peat layers.
In the composting process, grass charcoal can increase the content of organic matter, especially humic acid, in the compost, and can also change the color of the compost product, which is conducive to sales.
