Why Organic Fertilizer Prices vary widely

Now there are many kinds of organic fertilizer on the market, the market is chaotic, from 20, 30 yuan a package to more than a hundred. How to choose has been introduced to you before. Today we will share with you why the price of organic fertilizer is so different! The price of organic fertilizer depends mainly on raw materials and production process. Today, we put aside the production process to talk about the raw materials of organic fertilizer. Organic matter, simply understood as flammable carbon compounds. From the component analysis, there are hundreds of organic substances which can be used as raw materials of biological fertilizer. How to judge the quality of products according to raw materials?

There are two main indicators for judging the quality of organic matter. First, security, which is the first consideration. Safety is to analyze whether there are toxic and harmful ingredients in organic substances, mainly: pathogenic eggs, antibiotics, high-salt substances, strong acid and alkali substances, heavy metals. Some food industry wastes and wastes, such as soy sauce residue, need to add excessive salt in the process of extracting target components, which also affects the safety; some chemical industry wastes and river sludge contain heavy metals that exceed the standard. It also affects security. Organic materials with potential safety hazards have endless consequences. Secondly, the use effect is determined directly by the nutritive value of organic matter without considering the influence of fermentation technology. The nutritive components are mainly organic nutrition and inorganic nutrition, including protein content, starch, fat and crude fibre, and inorganic nutrition is mainly nitrogen. Phosphorus, potassium and trace elements. Of course, organic is the foundation, biological is the function, fermentation is the soul, no matter how high the nutritional value, without fermentation, it is difficult to reflect the effect.

Following is a brief classification and sorting of several types of organic matter frequently encountered in the market according to safety and use effect. [Cake meal] Soybean meal, corn germ meal, sprayed corn meal, bran, rapeseed meal, etc. Safety and nutritional value are very high (only oil is extracted during processing). [Food industry by-products] Various kinds of grains and residues, distillers'grains, vinegar grains, cassava residues, furfural residues, citric acid residues, sugar residues, starch residues, etc. The nutritional value is relatively high (all kinds of nutrients are reduced in the process), and the safety is basically up to the standard (in the case of high salt). [Agricultural waste] Mushroom residue, silkworm sand, straw, etc. The nutritional value is medium, the safety is relatively high, and there is basically no harmful substance added. [Livestock and poultry manure] Faeces from various farming industries; Safety needs to be treated, some ingredients like antibiotics are difficult to deal with, and most manure on the market has not undergone professional fermentation treatment, so the safety is relatively poor. Different feces have different nutritional value, the key is to eat what and digestive capacity, feed is better than simply grazing; chicken manure is better than cow manure, because chicken digestive system is simple, often said chicken is "rectum", digestive capacity is general, the remaining nutrients are relatively more, so chicken manure nutritional value is high. 。 Cattle are ruminants and have a strong digestive capacity, so the nutritive value of cow dung is lower, and so on. The overall nutritional value is OK, but after digestive system, the nutritional value is lower than that of food raw materials. [Drug factory residue]: Chinese medicine residue, abamectin residue, antibiotic residue, etc. Drug residue of traditional Chinese medicine (TCM) is the residual residue after boiling and processing of TCM. It has certain nutritional value, but its composition is complex and unstable, and its safety can not be guaranteed.   The residue of Abamectin and antibiotics (both metabolites of microorganisms) is essentially the residual nutrients and mycelia of fermentation bacteria after utilization. It has high nutritional value, but it has residual medicinal ingredients, so it should be used cautiously. (Some Avermectin organic fertilizers are added with Avermectin residue on the market) [Mineral Composition] Weathered coal, lignite, peat, peat, coal gangue, etc. Safety is very high. But the nutritional value is very low and belongs to the macromolecule substance with high stability. Only after chemical treatment or biological fermentation can the nutritional value be improved. [Domestic waste] Food and kitchen waste and other daily waste; It has certain use value, but the composition is too complex, unstable and difficult to use. Relevant products are rare. [Municipal Sludge] River Sludge, Sewerage Sludge, etc. Safety is very low, heavy metals often exceed the standard, and nutritional value is relatively low. Waste sludge from paper making, printing and dyeing, electroplating and leather factories; Safety is very low, heavy metals often exceed the standard, nutritional value is also very low.
