- Q: There are several kinds of compound fertilizer.
- Diammonium phosphate, monoammonium phosphate
- Q: How to use compound fertilizer
- Fertilizer fertilizer effect is long, should do basal fertilizer. A large number of tests have shown that both binary and ternary complexes are better. This is because the compound fertilizer contains nitrogen, phosphorus, potassium and other nutrients, especially early on the crop of phosphorus, potassium is extremely sensitive to the requirements of phosphorus, Controlled release compound fertilizer in the production process using the coating, granulation and other processes, fertilizer efficiency slow and smooth, than the simple decomposition of fertilizer, nutrient leaching less, high utilization rate, suitable for basal fertilizer. General acres of the amount of 30 to 40 kg. Compound fertilizer should not be used for seedling fertilizer and medium and late fat, to prevent greedy filial piety.
- 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: Organic fertilizer and compound fertilizer
- Compound fertilizer is mainly to provide carbon, phosphorus, potassium and other elements, the main advantage is the high nutrient content, fertilizer fast, fat strong, can play a quick effect and improve the role of the product; the disadvantage is generally free of organic matter, can only supply crop nutrients, Improving soil and cultivating soil fertility is less effective. Effective time is short, fertilizer can not be sustained. It is also easy
- Q: China's largest compound fertilizer business in the top 20 which?
- Currently know only Stanley, Kim Jong Il, Luxi Chemical
- Q: Compound fertilizer well-known brands which
- Now the market of poor quality of fertilizer too much, recommended like Sinochem, Huajin, Luxi, Yuntianhua, Yihua these are good, are the fertilizer industry leader, and large brands of quality assurance, sales are very good Of these brands, and if you do not understand, it is recommended that those famous brands online browsing, like buying a brand network is good, above the top ten brands of fertilizer recommended, where the brand information is quite comprehensive, I wish you good luck
- 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.
- Q: What is the compound fertilizer raw materials
- Nitrogen, phosphorus and potassium, as well as accessories
