Natural organic fertilizer, also called

Most of the understanding of organic fertilizer in China is that under the conditions of certain moisture, C n and ventilation, through the action of microbial fermentation, through the process of composting, organic fertilizer from an unstable state to a stable state.

At present, there is no widely accepted definition of organic fertilizer. Organic fertilizer can be used as an organic fertilizer or soil conditioner product.

What is organic fertilizer.

Broadly speaking: commonly known as farmhouse fertilizer, it is composed of various animal and plant residues or metabolites as raw materials, such as human and animal manure, straw, animal residues, slaughterhouse 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 fertilizer, 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.

What is organic fertilizer.

In a narrow sense: it refers to the use of various animal wastes (including animal manure; animal processing waste) and plant residues (cake fertilizers; crop straw; Defoliation; Branches; Grass peat, etc.) as raw materials, using physical, chemical, biological or a combination of the three, after a certain processing technology (including but not limited to stacking; High temperature; Anaerobic, etc.), eliminating the harmful substances (pathogenic bacteria, pest and disease eggs, weed seeds, etc.) to meet the harmless standards and the formation of a type of fertilizer that meets the relevant national standards (NY 525-2012) and regulations.

After the organic fertilizer is processed by biological matter, animal and plant waste, and plant residues, it eliminates the 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 long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, and is the main nutrient for green food production.

Commonly known as farmhouse fertilizer, it is composed of various animal and plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc.

Natural organic fertilizer is animal manure.

Composting Association of America (USCC).According to this private organization, organic compost is "the product obtained by the controlled biological decomposition of organic waste, and the heat generated during the decomposition process can make the raw materials harmless and stable to benefit the growth of plants, and its physical properties are completely different from the original raw materials." Compost is an organic matter resource with unique properties that can improve the chemical, physical and biological properties of the soil or growing substrate, and although it contains plant nutrients, it is not yet a typical fertilizer".

Organic fertilizer. The domestic understanding of organic fertilizer refers to the process of transforming waste organic matter (mainly agricultural waste) into fertilizer through the fermentation of microorganisms under artificial control and certain moisture, C n and ventilation conditions. Through the composting process, the organic matter is transformed from an unstable state to a stable humus substance, and its products do not contain pathogenic bacteria, do not contain weed seeds, and are odorless and fly-free, can be safely handled and preserved, and are a good soil conditioner and organic fertilizer.

Organic fertilizer is actually a dehydration process in the composting process, and because it mainly relies on the action of microorganisms and does not require external energy, it often has the characteristics of low input, low cost, and value-added use of products, and is welcomed by the waste treatment community.

Note USCC: A non-profit organization dedicated to recycling organic raw materials through composting. It is the only national organization for the composting industry in the United States.

USCC provides resources, educational materials, training, networking, and career development opportunities for professionals including compost production, marketing, organic residues, policymakers, managers, equipment manufacturers, product vendors, academic institutions, public agencies, nonprofits, and consulting engineering firms.

<> organic fertilizer refers to the fertilizer made from various animal manure, plant residues or metabolites through fermentation. Organic fertilizer, also known as "farmhouse fertilizer", contains nutrients that are mostly in an organic state.

There are many types of organic fertilizers, wide range of fertilizers, long fertilizer efficiency, can slowly release a variety of nutrients, continuously supply nutrients to crops, can also improve soil structure, coordinate water, fertilizer, gas and heat in the soil, and improve soil fertility and land productivity.

At present, organic fertilizer is a fertilizer that cannot be replaced by facility vegetable cultivation in the agricultural field, and the organic fertilizer commonly used in facility vegetable cultivation mainly includes commercial organic fertilizer and farmhouse fertilizer. The widespread use of organic fertilizer can make agriculture gradually begin to transform into pollution-free rough reed agriculture, so that more organic food, fruits and vegetables can be brought to people's tables. There are also many heaping and soaking methods for the harmless treatment of organic fertilizers, such as EM compost rot method, self-made fermentation and ripening heap rot method and factory harmless treatment.
