What are the organic fertilizers, and what are the organic fertilizers?

Organic fertilizer in a broad sense: commonly known as farmhouse fertilizer, including a variety of animals, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse organic fertilizer.

Waste, etc. In addition, it also includes cake fertilizer (rapeseed cake, cottonseed cake, bean cake, sesame cake, castor cake, tea seed cake, etc.); Compost; manure; manure; biogas manure; Green manure, etc. It is mainly used as a means to improve the physical and chemical properties of the soil, promote the growth of plants and the circulation of the soil ecosystem.

Some varieties of "organic fertilizer in a broad sense": Compost: a fertilizer made of all kinds of orange stalks, fallen leaves, grasses, animal and plant residues, and human and animal manure as raw materials, mixed with each other or mixed with a small amount of soil for aerobic fermentation and decomposition.

Manure: The raw materials used in manure are basically the same as compost, except that they are fermented under flooded conditions. manure;

It refers to the fertilizer made from the manure and straw bedding of pigs, cattle, horses, sheep, chickens, ducks and other livestock and poultry. Biogas fertilizer: In a sealed digester, organic matter is decomposed to produce by-products of biogas, including biogas liquid and residues.

Green manure: Organic fertilizer.

Use cultivated or wild green plants as fertilizer. Such as leguminous mung beans, broad beans, grass and trees, field cyanine, alfalfa, vetch and so on. Non-leguminous green manure includes ryegrass, fertile radish, small sunflower, manjianghong, water hyacinth, water peanut, etc.

Crop straw: Crop straw is one of the important fertilizer varieties, and crop straw contains essential nutrients for crops, such as N, P, K, CA, S, etc. Under suitable conditions, through the action of soil microorganisms, these elements are mineralized and returned to the soil for crop absorption.

Pure natural mineral fertilizers, including potassium mineral powder, phosphate rock powder, calcium chloride, natural potassium magnesium sulfate fertilizer and other natural substances that have not undergone chemical processing. These products must be certified organic and produced in strict accordance with organic standards before they can be used in organic farming. In addition, it is worth mentioning that in terms of potassium supplementation, CITIC Guoan's "organic natural potassium sulfate and magnesium sulfate fertilizer" can be selected to obtain organic product certification, which fills the domestic gap of organic natural mineral fertilizer and solves the problem of difficulty in potassium supplementation in organic agriculture.

Cake fertilizer: rapeseed cake, cottonseed cake, bean cake, sesame cake, castor cake, tea seed cake, etc. Mudman:

Unpolluted river mud, pond mud, ditch mud, port mud, lake mud, etc.

Nongxuan Biotech tells you:

1. Commercial organic fertilizer: Generally, the manufacturer has undergone biological treatment of organic fertilizer, and its pests and weed seeds have basically died after high temperature treatment, as long as it is a commercial organic fertilizer produced by regular manufacturers, it can be used with confidence.

2. Compost manure: generally known as farmhouse fertilizer, which is made of manure and straw, etc., if the compost is good, it can also be used with confidence.

3. Green manure: It is generally used in the field after planting green plants, such as alfalfa, milk vetch and so on.

Organic fertilizers mainly include:

1. Farm fertilizer.

2. Crop straw.

3. Green manure 4. Biogas fermentation fertilizer, pomace and mushroom waste residue.

5. Commercial organic fertilizer.

Nongxuan] organic fertilizer: The important role of applying organic fertilizer is to increase the organic matter of the soil. Although the content of organic matter only accounts for a few percent of the total amount of soil in the cultivated layer, it is the core component of the soil and the main material basis of soil fertility.

Organic fertilizers have a very important impact on the structure of the soil, the nutrients in the soil, energy, enzymes, moisture, aeration and microbial activity.

Plant source. Straw: common original corn straw, wheat straw, soybean straw, rice straw.

Contains high cellulose and lignin and other macromolecular substances, low nutrient content such as nitrogen, phosphorus and potassium (except legumes), it is rare to use this kind of material as organic fertilizer alone, and is generally used to increase the organic matter of fermentation materials and adjust the carbon and nitrogen ratio. This kind of raw materials are relatively abundant and cheap, but because these materials are mostly in the hands of agriculture, it is difficult to purchase a large area, and the seasonality is strong, and the annual production needs to be stocked in advance.

Meal: soybean meal, cotton meal, castor meal, pepper meal, peanut meal, etc., are mostly leftovers of agricultural product processing industry, and most of them are auxiliary materials. Organic fertilizer with meal as raw material can be called high-end organic fertilizer, because it is mostly feed grade, the cost of raw materials is high, and fermentation and rotting should not be controlled.

Mushroom bran: commonly known as mushroom residue, enoki mushroom residue, oyster mushroom residue, king oyster mushroom residue, etc., the raw materials are mostly distiller's grains, corn cob, rice husk powder, wheat bran, soybean meal and some nutrients. Bacterial bran has high organic matter, rich in bacterial protein, vitamins, trace elements and auxin, and the effect of organic fertilizer in fertility is better.

Animal origin. Animal manure: sheep manure, pig manure, cow manure, etc. are all good organic fertilizer raw materials. It has a high content of organic matter, but it is not easy to decompose due to the low fiber content. When used, it should be fully decomposed and fermented, and the eggs and weeds of diseases and insects, bacteria and weeds should be killed at high temperature.

Animal Processing Waste: Processing Waste, even.

There are many types of organic fertilizers, and generally commonly used organic fertilizers are tea seed cakes, rapeseed cakes, cottonseed cakes, bean cakes, sesame cakes, castor cakes, straws of various crops, animal and plant residues, human and animal manure, etc.

Organic fertilizer is processed from biological matter, animal and plant waste, and plant residues, eliminating toxic and harmful substances in it, and is rich in a large number of beneficial substances, including a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. It can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect, which can increase and renew soil organic matter and promote the reproduction of microorganisms.

Improving the physical and chemical properties and biological activity of soil is the main nutrient for green food production. Organic fertilizer, commonly known as farmhouse fertilizer, refers to a slow-acting fertilizer that contains a large amount of biological matter, animal and plant residues, excrement, biological waste and other substances. Organic fertilizer not only contains a large number of essential elements and trace elements for plants, but also contains rich organic nutrients, and organic fertilizer is the most comprehensive fertilizer.

Precautions and key points for organic fertilizer:

When the ground temperature is low, the microbial activity is weak, and the nutrient release of organic fertilizer is slow, so most of the application amount can be applied as basal fertilizer; When the ground temperature is high, the microbial decomposition ability is strong, if the amount of basal fertilizer is too much, before planting, the fertilizer is excessively decomposed by microorganisms, and after planting, it immediately plays a fertilizer effect, and sometimes may cause crops to grow.

Therefore, cultivate crops under high temperature conditions, reduce the amount of basal fertilizer and increase the amount of top dressing. Topdressing high-quality organic fertilizer crops need a lot of nitrogen, potassium and other nutrients during the rapid growth of crops, the nitrogen, potassium nutrient content in the general organic fertilizer is not high, in order to ensure the rapid growth of crops on the demand for nutrients, to choose high-quality organic fertilizer with high nitrogen and potassium nutrient content.

Feces and urine: including human feces, livestock feces, food, seabird droppings, silkworm sand, etc.

Cake fertilizer: including all kinds of cake fertilizer and fine residue fertilizer.

Marine fertilizer: animal marine fertilizer, plant marine fertilizer, mineral marine fertilizer: winter green manure, summer green manure, aquatic green manure, perennial green manure, wild green manure.

Herbitis: There are peat, lignite, humic acid fertilizers.

Miscellaneous fertilizers: smoked soil, pit soil, nitrate, garbage, chimney ash, fertilizer mud, plant ash, national slaughterhouse waste, etc.

Degree of industrialization: farmyard fertilizer and commercial organic fertilizer.

Different processing technology: commercial organic fertilizer, biological organic fertilizer, organic-inorganic compound fertilizer fermentation treatment is different: anaerobic fermentation organic fertilizer, aerobic fermentation organic fertilizer fermentation raw materials are different: straw organic fertilizer, soybean meal organic fertilizer, cow manure organic fertilizer, sheep manure organic fertilizer, home-made compost, etc.

Organic fertilizer has many benefits, and its use is becoming more and more common, so it must be used regularly for the sake of soil health and improving the quality of agricultural products.

There are many raw materials for the production of organic fertilizers, which can be divided into the following categories:

1. Agricultural waste: such as straw, soybean meal, cotton meal, etc.

2. Livestock and poultry manure: such as chicken manure, cow, sheep and horse manure, rabbit manure;

3. Industrial waste: such as distiller's grains, vinegar grains, cassava residue, sugar residue, furfural residue, etc.;

4. Domestic garbage: such as kitchen waste, etc.;

5. Urban sludge: such as river sludge, sewer sludge, etc.

Of course, the above raw materials need to go through fermentation and other processes.

1) Manure and compost.

It is rich in organic matter, has the effect of improving the physical properties of the soil, and is a complete fertilizer containing nitrogen (N), phosphorus (P) and potassium (K), which is mainly used as the base fertilizer for flowers in the open field.

2) Cow dung. It is a delay-acting fertilizer, the fertilizer effect is long-lasting, and it is mixed in the soil or used as top dressing with its leaching solution after it is fully decomposed.

3) Chicken manure. Completely fattened. High heat during fermentation, apply after sufficient decomposition, and do not touch the roots of the flowers directly. It can be fermented with 10 times water, and diluted 10 to 20 times when used to do top dressing.

4) Meal cakes.

It mainly contains nitrogen (N), but also phosphorus (P). It is mainly used as top dressing, but it can also be used as base fertilizer. Add 10 times water to ferment, and dilute 10 times when used to do top dressing.

5) Bone meal. Delay-acting fertilizer. It is suitable for use in high-temperature places such as greenhouses. It can be used as basal fertilizer, or it can be spread on the soil surface and mixed with topsoil as top dressing. It is better to mix with other fertilizers for fermentation. It can improve the quality of flowers and has a significant effect on enhancing the strength of flower stems.

6) Rice bran. It mainly contains phosphorus, promotes the decomposition of other fertilizers, and has a long fertilizer effect. It can be used as base fertilizer.

7) Grass ash.

It mainly contains potassium and has high fertilizer efficiency, but it is easy to make the soil compact. Species with weak roots and sowing are better used.

8) Horseshoe slices, horns.

Chop and mix with soil, make base fertilizer after rotting, and make base fertilizer for potted plants. It can also be soaked in water and diluted to make top dressing.
