What are the standards for organic fertilizer? What are the criteria for organic fertilizer?

Organic fertilizer is mainly used on plants and/or animals, and is a carbon-containing material applied to the soil to provide plant nutrition as its main function. It is processed from biological substances, animal and plant wastes, and plant residues, eliminating toxic and harmful substances, 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.

The current implementation standard is NY525-2012, replacing the original NY525-2011, issued on March 1, 2012 Implemented on June 1, 2012, issued by the Ministry of Agriculture of the People's Republic of China.

Functional role

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 fertilizers not only contain a large number of essential elements for plants.

Trace elements, but also rich in organic nutrients, organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizer in agricultural production is mainly manifested in the following aspects:

1. Improve the soil and fertilize the soil. After organic fertilizer is applied to the soil, organic matter can effectively improve the physical and chemical status and biological characteristics of the soil, mature the soil, enhance the fertilizer retention capacity and buffer capacity of the soil, and create good soil conditions for the growth of crops.

2. Increase output and improve quality. Organic fertilizers are rich in organic matter and various nutrients that provide nutrients to crops. After the organic fertilizer is decomposed, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products.

3. Improve the utilization rate of fertilizer. Organic fertilizer contains more nutrients but relatively low content and is released slowly, while chemical fertilizer has high nutrient content per unit and few components and is released quickly. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and chemical fertilizers.

Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and improves the utilization rate of fertilizer.

The country has issued the agricultural industry standard NY525-2012. Commercial organic fertilizer must be registered in accordance with the fertilizer registration management measures, and obtain the registration certificate number, before it can be circulated and sold in the agricultural market.

Appearance; Organic fertilizers are brown or gray-brown, granular or powdery, free of mechanical impurities, and free of foul odor.

The project indicators of organic fertilizer should meet the following requirements.

The heavy metal content, roundworm egg mortality and E. coli value indicators in organic fertilizers should meet the requirements of GB8172.

The latest national standard for organic fertilizers is GB 38562-2020 "Organic Fertilizers". This standard has been officially implemented since January 1, 2021, replacing the original GB 15963-1995 "Organic Fertilizer" standard.

The GB 38562-2020 standard stipulates the classification, naming, quality indicators, scope of use, production requirements, packaging and transportation, marking and labeling of organic fertilizers. It mainly includes the following aspects:

2.Quality indicators and requirements: organic matter content, organic nitrogen content, effective phosphoric acid content, available potassium content, heavy metal content and other indicators are stipulated.

3.Scope and method of use: guide farmers to correctly choose organic fertilizers, use non-organic fertilizers, and promote the rational use of organic fertilizers.

4.Production requirements and rock standards: It is stipulated that organic fertilizers must meet a series of production requirements and standards to ensure their quality and safety.

In addition, GB 38562-2020 also clarifies the relevant requirements for the packaging and transportation, marking and labeling of organic fertilizers, so as to ensure that organic fertilizers meet the requirements of relevant national laws and regulations in the production and use process.

The latest national standard for organic pruning is GB T 25487-2010 "Organic Fertilizer". The standard was published in 2010 and is still in force.

According to the standard, organic fertilizer refers to a soil conditioner made of animal and plant manure, waste, crop straw and manure as raw materials, after fermentation, decomposition and other treatments, which can provide nutrients required by plants, and can improve soil structure, adjust soil pH value and microbial community, and improve soil water and fertilizer retention performance.

The standard stipulates the classification, quality requirements, test methods, inspection rules and other aspects of organic fertilizers, including the detection methods and limit values of important parameters such as organic matter content, total nutrient content, heavy metal content, and microbial quantity. These regulations can help manufacturers produce organic fertilizers that meet quality requirements, while also ensuring that consumers can use safe and effective organic fertilizers.

The latest national standard for organic fertilizer is "Organic Fertilizer" (GB T 34727-2017), which was issued in 2017 and implemented on January 1, 2018. This standard is the basic standard of China's organic fertilizer industry, which stipulates the classification, name, physical properties, chemical properties, microbial indicators, heavy metal content, radionuclide content, biological fertilizer and organic fertilizer mixed fertilizer use requirements of organic fertilizer.

The standard strictly supervises the quality and safety of organic fertilizer and roll, including the restriction of heavy metal content, radionuclide content and other pollutants in Youshitan early machine fertilizer, as well as the number and type of microorganisms in organic fertilizer, so as to ensure the quality and safety of organic fertilizer.

In addition, the standard also stipulates the method of use and scope of use of organic fertilizers, including not to be used in specific areas, and safety regulations should be observed when using them, which ensures the correct use and safety of organic fertilizers.

In short, "Organic Fertilizer" (GB T 34727-2017) is the basic standard of China's organic fertilizer industry, which regulates the requirements for the production, sales, and use of organic fertilizers, and ensures the quality and safety of organic fertilizers.

The Ministry of Agriculture and Rural Affairs issued an announcement that 153 standards such as "Organic Fertilizer" have been approved by experts and are now approved for release as agricultural industry standards of the People's Republic of China. The "Organic Fertilizer" standard will be implemented from June 1, 2021, and other standards will be implemented from November 1, 2021.

Organic fertilizer is divided into farmhouse fertilizer and green manure.

1. Farm fertilizer, farm fertilizer includes manure fertilizer, compost fertilizer, soil miscellaneous fertilizer, oil cake fertilizer and humic acid fertilizer.

1. Manure and urine manure, manure and urine manure are human manure, livestock and poultry manure and various circle fertilizers. Manure fertilizer is rich in calcium, magnesium, sulfur and a variety of trace elements, is rich in organic matter and a variety of nutrients of complete fertilizer. The nutrients in various circle fertilizers are mainly organic, crops can not be directly absorbed and utilized, fresh circle fertilizer should not be directly applied to farmland, must be fermented by composting, under the action of high-temperature fiber decomposition bacteria, fully decomposed after application to improve fertilizer efficiency.

2. Compost and compost.

Compost is to continue to accumulate and ferment crop straw, various garbage, fallen leaves, sludge, etc., to achieve the decay of these raw materials, compost is rich in nutrients, can provide crop nutrients, and can improve the soil, is similar to the circle of manure organic fertilizer, also called artificial manure.

3. Soil miscellaneous fertilizer, including all kinds of ash fertilizer, garbage fertilizer, mud fertilizer, rock ash, lime, gypsum, soil fertilizer and slaughterhouse waste materials. A small part of the soil miscellaneous fertilizer can be applied alone, such as plant ash, rock ash, lime, gypsum. Most are mixed with other farmyard manures.

4. Oil cake fertilizer, including rapeseed cake, tung seed cake, cottonseed cake, tea seed cake, black tree seed cake, soybean meal, sesame cake, peanut cake, etc., these fertilizers have high organic matter content, generally 75-85%, rich nitrogen content, complete nutrients, and long-lasting fertilizer effect. Oil cake fertilizer should be fermented before application.

5. Humic acid fertilizers, including peat, lignite, weathered coal, etc., and the processed products include ammonium humate, ammonium humate phosphorus, humic phosphorus, potassium humate, sodium humate, etc.

2. Green manure is directly or indirectly applied as fertilizer using cultivated or wild green plants, such fertilizers include vetch, purple flower, arrowtongue pea, milk vetch, broad bean, pea and aquatic plants.

Organic manure is mainly human manure manure, manure manure, manure and green manure and other fertilizers. Farm manure has the characteristics of many types and fast fertilizer efficiency, which can improve the soil, increase soil fertility, improve soil nutrient vitality, and purify the soil ecological environment.

Human manure is mainly the farmer's farmhouse fertilizer after decomposing and fermenting into harmless treatment, which is a high-quality organic fertilizer.

Organic fertilizers are suitable for all kinds of soils, but also for a variety of crops, to promote the normal development and growth of root systems. However, it should be used sparingly for crops such as tobacco and sugar beets so as not to affect the quality.

Decomposed and fermented human manure can be used as base fertilizer or top dressing; Due to its high nutrient concentration and fast fertilizer efficiency, top dressing is the best choice.

Manure is mainly an organic fertilizer made by mixing livestock and poultry manure with bedding or organic additives, and the degree of decay of manure raw materials also determines the nature and quality of manure.

Compost is mainly formulated without the use of any chemicals. Compost can reduce soil pests and diseases, is the best way to improve the soil and a high-quality amendment, but also to improve the physical properties, chemical structure and biological environment of the soil, to avoid the soil breeding various viruses.

In fact, in rural areas, there are many types of organic fertilizers, and their properties are similar, and they are very high-quality farm fertilizers.
