What are the organic fertilizer raw materials?

What are the raw materials of organic fertilizer? What are the benefits? Please introduce that there are many kinds of organic manure raw materials, such as livestock and poultry manure and crop straw, as well as green manure, cake meal, plant ash, sludge, domestic waste and sewage, which can be used as organic fertilizer. Land cultivation network sorted out the advantages and disadvantages of livestock and poultry manure as organic fertilizer, which are listed below for netizens' reference. The shortcomings of livestock and poultry manure as the raw material of organic fertilizer are as follows: 1. The organic fertilizer with livestock and poultry manure as the main raw material contains heavy salt, which is easy to salinize the soil, increase the soil salt concentration, improve the critical point of fertilizer effect of nutrient elements on crops, and increase the amount of fertilizer application. In serious cases, it will cause seeds not to germinate, burn seedlings and burn roots. 2. The nitrogen of organic fertilizer of livestock and poultry manure is mainly uric acid form nitrogen, uric acid salt can not be directly absorbed and utilized by crops, it consumes a lot of oxygen and releases carbon dioxide gas when it decomposes in the soil, so it is easy to damage the roots of crops. 3. Bacillus, Escherichia coli and more than ten genera of fungi and some parasites can be detected in livestock and poultry manure organic fertilizer, which carries more bacteria and eggs, and is easy to cause diseases and insect pests. 4. The content of trace elements in some livestock and poultry manure exceeds the standard. In livestock and poultry feed, due to the addition of a large number of trace elements such as copper, iron, zinc, manganese, cobalt, selenium and iodine, many trace elements not absorbed by livestock and poultry are accumulated in livestock and poultry feces. According to the investigation of relevant units, the heavy metal pollution in the feed used in some large and medium-sized livestock and poultry farms is relatively serious, and the contents of copper, zinc, chromium, lead and cadmium generally exceed the national feed hygiene standards or pollution-free feed production standards. in particular, toxic elements such as arsenic and mercury have also exceeded the standard. 5. Most livestock and poultry manure or organic manure with livestock and poultry manure as the main raw material is acidic and easy to produce bacteria, which must be neutralized with lime to cause soil consolidation. 6. The organic fertilizer of the main raw materials of livestock and poultry manure is hot, and it is easy to burn seedlings and roots when used in high temperature weather. 7. The organic fertilizer with livestock and poultry manure as the main raw material needs to be used after composting, which is manual and has a long cycle. 8. The organic fertilizer with livestock and poultry manure as the main raw material has many impurities, great purity deviation and unstable content, which can not guarantee the nutrient content and effect of application. The advantages of livestock and poultry manure as organic fertilizer are as follows: 1. It can promote crop production and income: organic fertilizer produced by livestock and poultry manure contains rich organic matter, which can comprehensively provide crop nitrogen, phosphorus and potassium and a variety of medium and trace elements, and greatly improve the quality of agricultural products. After application, melons and vegetables are sweet, rice is fragrant, and can effectively improve soil physical and chemical properties, loosen soil, enhance soil permeability and greatly improve soil fertility. The bio-organic fertilizer components of livestock and poultry manure contain nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solubilizing bacteria and so on. After application, the nutrients in the soil can be transformed into crops and provide nutrients to crops continuously. 2. It can effectively promote crop growth: the application of organic fertilizer made from livestock and poultry manure can make a large number of beneficial active bacteria multiply rapidly, effectively inhibit the growth of harmful microorganisms, produce a variety of enzymes at the same time, and promote the healthy growth of crops. enhance crop resistance and pest resistance, reduce pesticide application, and alleviate continuous cropping obstacles. 3. It can effectively improve soil fertility: a large number of beneficial active bacteria directly participate in the process of soil material and energy transformation, humus formation and decomposition, play an adhesive role in soil aggregate structure, effectively improve soil physical properties, enhance soil permeability, water and fertilizer conservation capacity, prevent soil consolidation and acidification, improve soil fertility, improve fertilizer utilization efficiency, reduce fertilization costs, and make the land realize a virtuous cycle. The reasons for livestock and poultry manure as organic fertilizer need to pay attention to: first, the nitrogen in fresh chicken manure is mainly uric acid salts, which are not easily absorbed and utilized by crops directly, and are harmful to the growth of crop roots. Therefore, this kind of manure should be accumulated and fermented before it can be applied. Chicken manure fermentation temperature is high, easy to damage plant young roots, fresh manure is generally not suitable for direct application, need to add sewage or mixed with other organic fertilizer for composting, after composting fully mature before application. In particular, it should be noted that because the additives in chicken feed contain high levels of hormones, they should be removed by stacking; at the same time, chicken feces and urine are easy to contain Ascaris lumbricoides eggs, so they need to be passed and piled up for about 40 days to kill. Therefore, it is suggested that poultry manure should be composted at room temperature for 60 days, which can be safely used in the production of pollution-free vegetables, but the composting time in winter is 2 months longer than that in summer and autumn due to low temperature. In addition, we should also remind farmers that when applying chicken manure, it should be fully mixed with the soil, not too thick, so as not to hurt the roots; the application of chicken manure should be uniform, so that the plant can grow evenly and be easy to manage; when planting, the root system must not be in direct contact with chicken manure, and when the drains are cultivated on the back of the border, it is best to have an isolation layer of 10 to 20 centimeters. Note that pig manure also contains Ascaris lumbricoides eggs, and it takes about 50 days to kill them The hormone content of the additive is also very high, and it needs to be treated by composting, and it takes more than 20 days to compost cow manure. Therefore, it is suggested that farmers should compost at room temperature for 60 days before applying animal manure, which can be safely used in the production of pollution-free vegetables. However, due to the low temperature in winter, the composting time in winter is 2 months longer than that in summer and autumn. In view of the above advantages and disadvantages of organic fertilizer raw materials, it is suggested that farmers should be fully mature when using these organic fertilizers, and if conditions permit, it is best to choose commercial organic fertilizers that are more reputable and produced in large-scale industrialization on the market.
