Why are the prices of organic fertilizers so different? In w
There are many kinds of organic fertilizer in the market, and the market is in disorder. From 20 yuan to 30 yuan a package, to a hundred or more, we can share with you why the price of organic fertilizer is so poor! The price of organic fertilizer depends on raw materials and production technology. We leave the production technology aside, let alone the raw materials of organic fertilizer.
Organic matter, simple understanding is combustible carbon compounds. From the component analysis, hundreds of organic substances can be used as bio fertilizer raw materials. How to judge the advantages and disadvantages of products according to the raw materials?
The main reference is to judge the advantages and disadvantages of organic matter. First, sex, this is the first to consider. Sex is to analyze whether there are toxic and harmful components in organic matter, mainly including: eggs of bacteria, high salt substances, strong acid and alkali substances, heavy metals. The results showed that the bacteria and eggs, strong alkaline substances and so on in the feces of livestock and poultry had influence on the quality of the bacteria and eggs; Some food industry leftovers and wastes, such as soy sauce residue, need to add excessive salt and influence in the process of extracting target components; Some chemical industrial wastes and heavy metals in river sludge exceed the standard and also affect the quality. The organic material with hidden danger will have endless future problems. The second is the effect of use. The nutritional value of organic matter directly determines the effect of the product without considering the influence of fermentation technology. The nutritional components mainly include organic nutrition and inorganic nutrition, among which the organic nutrition is mainly protein content, starch, fat, crude, etc; The inorganic nutrition is mainly nitrogen, phosphorus, potassium and trace elements. Of course, organic is the foundation, biology is function, fermentation is soul, and no higher nutritional value can reflect the effect without fermentation. The following will be the market often exposed to several types of organic matter, according to the sex and use effect of two aspects, a brief classification and sorting:
[cake meal] soybean meal, corn germ meal, jet corn meal, bran, rapeseed meal, etc; The sex and nutritional value are very high (only the oil part is extracted during the processing);
[by-product of food industry] a variety of grains and dregs, such as distillery, vinegar, cassava, furfural, citric acid, sugar and starch; The nutritional value is relatively high (all kinds of nutrients in the process of processing are reduced), and the sex is basically up to standard (with high salt conditions);
[agricultural waste] mushroom residue, silkworm sand, straw, etc; The nutritional value is medium, the sex is high, and there is no harmful substance;
[livestock and poultry feces] feces of various aquaculture industries;
Sex needs to be treated, some components like it is difficult to deal with, now most manure on the market has not been fermented, so sex is relatively poor. Different fecal nutrition values are different, the key to see what to eat and digestion energy, eat feed than simply eat grass better; Chicken manure is better than cow manure, because the chicken digestion system is simple, often said that chicken is "straight intestine", digestion can be general, the remaining nutrients are relatively more, so the nutritional value of chicken manure is high. Cattle are ruminants, digestion can be very strong, so cow manure nutritional value is lower, and so on. The overall nutritional value is OK, but after the digestion system, the nutritional value is lower than that of the food raw materials.
[pharmaceutical plant drug residue] Chinese medicine slag, avermectin slag, drug residue, etc;
The residue of traditional Chinese medicine is the residue after the preparation and processing of traditional Chinese medicine. Some of them have nutritional value, but the composition is complex, and the composition is unstable and has the characteristics. Avermectin and (both microbial metabolites) residue are the remaining nutrients and mycelium after fermentation bacteria are used. The nutritional value is relatively high, but the drug-resistant components are left, so use them carefully（ Some of the avermectin organic fertilizer on the market is added with Avermectin Residue)
[mineral composition] weathered coal, lignite, peat, peat, peat, coal gangue, etc; It's very sexual. But the nutritional value is very low, which belongs to the macromolecular substance with high stability. The nutritional value of the products can be improved only after chemical treatment or biological fermentation;
[domestic waste] various daily life wastes such as kitchen waste; Some of them are of great value, but the components are too complex, and the composition is very unstable and difficult to use. Few related products are found;
[Urban Sludge] river sludge, sewage sludge, etc; The sex is very low, and heavy metals often exceed the standard, and the nutritional value is also relatively low;
[chemical industrial waste] waste sludge from paper making, printing and dyeing, electroplating, leather factory and other waste; The sex is very low, often appear heavy metal exceed the standard, the nutrition value is also very low.
