Fertilizer is produced and refined by the manufacturer!
General farmyard manure is suitable for all land! Fertilizers need to be tested, and whatever the land needs is used. . . Urea, ammonia and the like! There are many kinds!
The difference between chemical fertilizer and artificial fertilizer lies in human feces, manure, compost, compost, biogas manure and waste fertilizer.
What is the difference between chemical fertilizer and farmyard manure? Fertilizer is obtained through industrial synthesis, and its composition is certain. For example, urea, such as ammonium bicarbonate (commonly known as ammonium bicarbonate in my hometown), and even compound fertilizer, their composition is very certain. When different fertilizers are mixed in a certain proportion, most of them are inorganic. The advantage of using chemical fertilizer is that it can suit the right medicine and be more targeted. The disadvantage is that they may cause soil hardening or pollute water sources.
Farmhouse manure generally comes from animal carcasses and feces, as well as crop straws. These things are quite complicated, mostly organic, similar to some amino acids, polysaccharides, fibers and so on. , and is usually metabolized by some microorganisms into other relatively simple things. The composition of farmyard manure from different sources will be different. For example, there is more urea in animal manure and more sugar in straw. Farmhouse manure is characterized by many nutrients, which can make up for everything, but it seems that everything will be owed.
What's the difference between fertilizer and feed? Fertilizer is for plants and feed is for animals.
What is the difference between controlled release fertilizer and ordinary chemical fertilizer? The nitrogen, phosphorus, potassium and various trace elements needed by crops are mixed in bags according to the proportion needed by crops. Fertilizer is packaged in a special packaging bag with micropores and released to the outside through the micropores of the packaging bag.
According to the principle of thermal expansion and cold contraction, the micropores of the packaging bag automatically expand and contract according to the temperature, thus achieving the purpose of controlling the release rate of nutrients. With the increase of temperature, micropores are broken, nutrient release speed is gradually accelerated, crop roots are broken, and required nutrients are increased. The crop is released continuously and stably throughout the whole process, and the nutrient supply is synchronized with the crop demand. There is less rain, and less fertilizer is released with water loss. The loss of fertilizer in the bag is almost affected by the soil type, which creates conditions for real quantitative fertilization or precise fertilization.
1, the bag controlled slow release controlled release fertilizer has high efficiency and utilization rate.
2. Bag fertilizer control can improve crop yield and crop quality.
3. Bag-controlled fertilizer slow-release and controlled-release technology. Real crops need accurate and quantitative fertilization.
4. Minimize leaching loss and reduce the beneficial effects of environmental pollution.
Excuse me, the difference between chemical fertilizer and pesticide is to provide nutrition for crops, and pesticides help crops kill innocent small animals (such as locusts)
What kind of fertilizer is bag controlled slow release fertilizer, and what is the difference with other fertilizers? Bag fertilizer control is to mix nitrogen, phosphorus, potassium and various trace elements needed by crops according to the proportion needed by crops, and then wrap them in special packaging bags with micropores, and the fertilizer releases nutrients through the micropores on the packaging bags.
According to the principle of thermal expansion and cold contraction, the micropores on the packaging bag can automatically expand and contract according to the temperature and moisture content, thus achieving the purpose of controlling the release rate of nutrients. With the increase of temperature and rain, the micropores will continue to expand and the release rate of nutrients will gradually accelerate. At this time, the root activity of crops will also accelerate and the required nutrients will also increase. This fertilizer will release nutrients continuously and steadily during the whole growth process of crops, and the supply of nutrients is in good synchronization with the demand of crops, neither more nor less. If it rains and waters, only a small part of the fertilizer released at that time will be lost with the water, and other fertilizers will still be in the bag and will not be lost. Almost unaffected by soil types, it creates conditions for realizing real quantitative fertilization or precise fertilization.
1, bag controlled slow release controlled release fertilizer has long fertilizer efficiency and high nutrient utilization rate.
2. Bag fertilizer control can increase crop yield and improve crop quality.
3. The slow-release and controlled-release technology of bag-controlled fertilizer really achieves accurate and quantitative fertilization according to the needs of crops.
4. Minimize leaching loss and reduce environmental pollution and adverse effects.
Is chemical reagent urea the same as fertilizer urea? Urea is also called carbonyl diamine, carboxamide and urea. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen, also known as urea (the homonym of urine). Its chemical formula is CON2H4, (NH2)2CO or CN2H4O, and its international name is urea. The appearance is white crystal or powder.
Fertilizer problem (14 * 2)/(14 * 2+4+16 * 3) * 90% = 31.5%
What are the disadvantages of chemical fertilizer? In order to produce more agricultural products, a lot of chemical fertilizers must be put in. At present, fertilizers used in production are mainly divided into two categories, one is organic fertilizer, such as gray manure, manure and green manure, and the other is chemical fertilizer, such as urea, ammonium phosphate and potassium chloride.
The main component of chemical fertilizer is inorganic compound, which is processed and decomposed by chemical fertilizer plant. For example, under the conditions of high temperature, high pressure and catalyst, hydrogen and nitrogen can synthesize ammonia, and then ammonia reacts with carbon dioxide to finally produce urea. For another example, ordinary superphosphate can be made by decomposing phosphate rock powder with sulfuric acid.
Compared with organic fertilizer, chemical fertilizer contains higher fertilizer components. Because of the high content of effective components and small volume, it is convenient for transportation and application, but it is not advisable to use too much at a time, otherwise it will cause the loss of fertilizers and agricultural products. Except for a few varieties, most fertilizers are easily soluble in water, easily absorbed and utilized by plants, and belong to quick-acting fertilizers, but they are easy to deliquesce and agglomerate, resulting in nutrient loss or inconvenient application. At the same time, some chemical fertilizers contain by-products that will adversely affect soil and crops, and some chemical fertilizers, such as ammonium sulfate, will cause soil hardening when used alone during crop growth. In addition, excessive application of chemical fertilizers may also lead to environmental pollution. Therefore, the application of chemical fertilizer should be based on the nature of chemical fertilizer, the demand of crops for nutrients, and the growth conditions of climate, soil and other crops, so that chemical fertilizer can play a greater role in increasing production.
