What are the characteristics of organic fertilizers as fake raw materials? How to identify fake organic fertilizers? In recent years, the country has begun to promote organic fertilizers, giving more preferential policies to organic fertilizers. Some people who want to opportunistically take the initiative to start thinking about it and start making fakes in organic fertilizer raw materials. In recent years, organic fertilizers have been used more and more in agricultural production, but there are also many fake organic fertilizers. There are even unhealthy commercial households to gain weight, color the mud, add chicken feathers to fake the real! Deceptive organic fertilizer, generally use the following five things as raw materials:
Sludge deposited from urban sewage: Although it contains a certain amount of organic matter and NPK components, such raw materials do not cost money, and the processing cost is very low, but heavy metals and E. coli are seriously exceeded, which easily leads to dead roots and dead trees. It is easy to cause malignant cancer after eating.
Sludge deposited from industrial wastewater: Although this type of sludge also contains a large amount of elements and organic matter, heavy metals are also seriously exceeding the standard, which can cause rotten roots, dead trees, and serious pollution of the soil.
Paper mill waste: This fertilizer, the main ingredient is lignin. It is an organic matter that is extremely difficult to absorb. Moreover, many Chemical Raw Materials are added in the process of papermaking, and most of these raw materials remain in the waste. It has great damage to the soil and has a great influence on the roots.
Weathered coal: It belongs to the apparent organic matter and cannot be the carbon source of soil microbes. The real active ingredient in weathered coal is humic acid, but not deep processing is an ineffective organic nutrient.
MSG factory waste: strong acidity. Although it is a food waste, it is not necessarily a good raw material for organic fertilizer.
The soil needs organic fertilizer, but it does not require cheap organic fertilizer, and it does not require fake organic fertilizer. Xiaobian here reminds the broad masses of farmers to polish their eyes!
How to distinguish the quality of organic fertilizer?
From the perspective of raw materials, organic fertilizer is roughly divided into six categories: animal organic fertilizer, cake organic fertilizer, straw organic fertilizer, organic fertilizer for manure, organic fertilizer for domestic garbage, and organic fertilizer for coal gangue.
Animal organic fertilizer: the best organic fertilizer, but the manufacturing cost is too high, whoever can use this organic fertilizer is basically more money to burn, not to discuss.
Cake-type organic fertilizer: first look at the size of the bag, about the same weight of the compound fertilizer is not more than twice the size; then open with water to see, basically in suspension is the cake-like organic fertilizer; if it is suspended But the bag is small, that is, the water is too high, find a convenient bag with a pound of two pounds, put it under the sun, the water is clear at a glance.
Straw-based organic fertilizer: it is a conscience organic fertilizer. The bag is large, more than twice the volume of the same weight compound fertilizer, floating on the water side with water.
Fecal organic fertilizer, not too crowded, is not a good organic fertilizer. There is no smell, it is not fermented, it is not recommended to use; fermented well, no smell, use it. It is soaked in water, there are sediments in the sediment, and some of the suspensions are mostly manure-based organic fertilizers.
Domestic waste organic fertilizer: It can be said that it is good, it can also be said that it is not good organic fertilizer. If all the food-based garbage is a good organic fertilizer, it is feared that some wastes such as batteries and convenience bags will be very harmful, and there are many fertilizers and sediments produced by the garbage, and the organic matter content is limited. The traits are similar to the manure-like organic fertilizers, and the sediment-like sediment particles are relatively fine. (Source: Agricultural Finance Network Agrochemical Collection )

China has become the world's largest producer of Antipyretic And Analgesic drugs, with the output of aspirin, paracetamol and analgin exceeding 10,000 tons, and the output of phenacetin, aminopyrine and antipyrine exceeding 1,000 tons. At present, the production of Antipyretic analgesics is growing rapidly in China, and it is expected that it will increase by about 8% in the future. For antipyretic analgesic supporting production of intermediates large output, many manufacturers. With the growth of antipyretic and analgesic drugs, their intermediates have also gained rapid development. Now we have 3 GMP standard workshop, Meanwhile, the factory is equipped with the researching and quality inspection centre, with strong technology research and development strength.
