- Q:Organic fertilizer and compound fertilizer
- Organic fertilizer organic fertilizer: mainly refers to a variety of animals and plants, after a period of fermentation and decomposition of the formation of fertilizers (including processed rapeseed cake, there is no smell). Organic fertilizer contains a large number of biological substances, animal and plant residues, excreta, biological waste and other substances, the application of organic fertilizer can not only provide comprehensive nutrition for crops, and fertilizer effect, can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical Nature and biological activity, is the main nutrient source for green food production. Composting with a variety of orange straw, leaves, grass, animal and plant residues, human and animal manure as raw material, mixed with a small amount of soil and an organic fertilizer. Composting composting raw materials and composting is basically the same, but in the flooding conditions for fermentation. Manure refers to the pig manure, cattle, horses, sheep, chickens, ducks and other livestock and poultry manure and straw dregs made of retting fertilizer. Biogas Fertilizer In sealed biogas digesters, organic matter is decomposed to produce byproducts of biogas, including biogas and debris. Green fertilizers are cultivated or wild green plants are used as fertilizers. Such as beans, green beans, beans, sweet grass, Tian Jing, alfalfa, vetch and so on. Non-leguminous green manure with ryegrass, fertilizer radish, small sunflower, full of river red, water hyacinth, water peanuts and so on. Crop Straw Crop Straw is one of the important organic fertilizers. Crop Straw contains the nutrients necessary for the crop N, P, K, Ca, s and so on. Under suitable conditions through the role of soil microorganisms, these elements through the mineralization and then back to the soil, for crop absorption and utilization.
- Q:There are several kinds of compound fertilizer.
- Nitrogen, phosphorus, potassium three nutrients, at least two kinds of nutrients that only by the chemical method of fertilizer, is a compound fertilizer.
- Q:Is the compound fertilizer alkaline?
- As the crop absorbs the chemical nitrogen fertilizer in the yin, the number of cations is not equal, when the absorption of cations more than anions, can make the soil acidification fertilizer called physiological acid fertilizer.
- Q:Compound fertilizer well-known brands which
- , Sunny days, oriental red, Yang Feng, Ba Tian, day ridge, Stanley force,
- Q:What is the compound fertilizer raw materials
- Nitrogen, phosphorus and potassium, as well as accessories
- Q:China's largest compound fertilizer business in the top 20 which?
- Zhonghua, middle peasants, Stanley, Yufeng, Yutian, Luxi chemical, heart to heart, day ridge, Fufeng, sunny days, Kim Jong-il, housewife, Zhongyuan Dahua, Caesar, Apollo, , Red square, three elements, lotus, diverse, Huafeng, Western, Golden Earth, six countries, Shi Fengfeng, etc.
- Q:How to use compound fertilizer
- Compound fertilizer, whether it is low concentration or high concentration, the application should pay attention to control the amount of flowers, and fertilizer must be fully mixed with soil to prevent the root, while the best use of potassium sulfate fertilizer, the current use of fertilizer on the base Combined with organic fertilizer, try not to use inorganic fertilizer.
- Q:The role of compound fertilizer
- Compound fertilizer, also known as three elements compound fertilizer, mainly nitrogen, phosphorus, potassium three elements, is the most essential elements of plant growth. Mainly used for agricultural production, the average plant fertilization three to four times a quarter, each time each plant Roughly 10 to 20 grams, watered water, then the general concentration of 2%, extensive management can also be applied after irrigation. All plants can be applied.
