Organic fertilizer is the right way to grow green crops while achieving pollution-free and contamination-free standards. Due to the excessive demand for green food and the promotion of organic fertilizers by government departments, there are many kinds of organic fertilizers. So, what kind of organic fertilizer helps to plant green farming? In fact, we must first know what kind of raw materials are used in organic fertilizers so that we can effectively judge what kind of organic fertilizers are beneficial to the soil in the field. Description: The types of organic fertilizer granules through the relevant investigation found that there are many raw materials that can produce organic fertilizer, we can follow the following methods to distinguish.
First, according to the source of raw materials classification.
(1) Crop straw and other plant residues. Including straw, wheat straw, corn straw, garden waste, etc.
(2) Livestock and poultry manure. For example, pig manure, cow manure, sheep manure.
(3) Agricultural by-products by-products. Such as soybean meal, vegetable cake meal, MSG residue, mushroom residue, etc.
(4) Residential waste. Such as food waste, grass ash, etc.
(5) Other raw materials. Such as digestate, peat, grass wood ash, sludge, urban sludge, etc.
Second, according to the primary and secondary function classification.
1. The main raw materials. Usually the main raw materials account for 30%-80% of the total raw materials, consisting of one or several raw materials. Commonly used main ingredients are livestock manure, straw powder, bacteria residue, etc.
2. Accessories. It is some raw materials mainly used to adjust the moisture, carbon and nitrogen ratio, acidity and permeability, composed of one or several raw materials. Usually this kind of raw material accounts for less than 40% of the total material, and the proportion of single material does not exceed 20%. Commonly used auxiliary materials are wheat bran, soybean meal, peat, grass ash, quicklime, etc.
Third, according to the nature of raw materials can be divided into carbon-containing raw materials, nitrogen-containing raw materials and conditioning agent raw materials.
1. Carbon raw materials. Refers to raw materials with high organic carbon content, usually used as the main composting materials, such as rice straw, rice husk, mushroom residue, etc.. In addition to rice straw compost, most of the raw materials containing carbon are used as auxiliary materials to adjust the moisture content, carbon to nitrogen ratio, compost density and improve the permeability of the material.
2. Nitrogen-containing raw materials. Generally refers to the carbon to nitrogen ratio of less than 30:1 raw materials, such as livestock manure; there are some high nitrogen raw materials used as auxiliary materials to adjust the carbon to nitrogen ratio, such as soybean meal, fish meal, etc.
3. Conditioner type raw materials. Mainly refers to the raw materials used to adjust the pH value, such as lime to adjust acidity, gypsum to adjust alkalinity, etc.
Generally speaking, the production process of organic fertilizer includes three stages: organic fertilizer
fermentation process - organic fertilizer granulation process - organic fertilizer packaging process. But the required equipment includes: organic fertilizer dump truck, organic fertilizer crusher, organic fertilizer mixer, organic fertilizer granulator, organic fertilizer dryer, organic fertilizer cooler, organic fertilizer screening machine, organic fertilizer coating machine, automatic packaging scale and other equipment.
The above is what we have about organic fertilizer production line, I hope it can help you are concerned about the organic fertilizer equipment!
