Organic fertilizer advantages and effects Organic fertilizer advantages Organic Fertilizer Effects Organic fertilizer, commonly known as farmyard fertilizer, refers to slow-acting fertilizers containing large amounts of biological matter, animal and plant residues, excreta, and biological waste. Organic fertilizer not only contains a large number of elements and trace elements necessary for plants, but also contains abundant organic nutrients. Organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizers in agricultural production is mainly manifested in the following aspects: Source: wolfberry people contributing authors: Liuqi Peng Chen Zhongpeng
Antiviral:
Antiviral drugs
are a class of medication used specifically for treating viral infections. Like
antibiotics and broad-spectrum antibiotics for bacteria, most antivirals are
used for specific viral infections, while a broad-spectrum antiviral is
effective against a wide range of viruses. Unlike most antibiotics, antiviral
drugs do not destroy their target pathogen; instead they inhibit their
development.
Antiviral drugs
are one class of antimicrobials, a larger group which also includes antibiotic
(also termed antibacterial), antifungal and antiparasitic drugs, or antiviral
drugs based on monoclonal antibodies. Most antivirals are considered relatively
harmless to the host, and therefore can be used to treat infections. They
should be distinguished from viricides, which are not medication but deactivate
or destroy virus particles, either inside or outside the body. Antivirals also
can be found in essential oils of some herbs, such as eucalyptus oil and its
constituents.Related Products:antiviral drugs,anti-cancer drugs.
Anti-cancer:
Anticancer, or
Antineoplastic, drugs are used to treat malignancies, or cancerous growths.
Drug therapy may be used alone, or in combination with other treatments such as
surgery or radiation therapy.

1 Compared with chemical fertilizers:
(1) The nutrients of biological organic fertilizers are complete; only one or more nutrient elements of fertilizers are available.
(2) Bio-organic fertilizers can improve the soil; regular use of fertilizers can cause soil compaction.
(3) Bio-organic fertilizers can improve product quality; excessive application of chemical fertilizers leads to poor product quality.
(4) Biological organic fertilizers can improve the rhizosphere microbiota of crops and increase their resistance to diseases and insect pests. Fertilizers are a single crop microbial population and are prone to pests and diseases.
(5) Bio-organic fertilizers can promote the use of chemical fertilizers and increase the utilization of chemical fertilizers. Fertilizers alone can easily cause the fixation and loss of nutrients.
2 Compared with refined organic fertilizer:
Refined organic fertilizer is a commodity organic fertilizer that is packaged and sold after the livestock manure has been dried and crushed.
(1) The bio-organic fertilizer is completely decomposed and does not burn roots or rotting seedlings; the refined organic fertilizers are not cooked and will be cooked in the soil after being used directly, which will cause burning phenomenon.
(2) The bio-organic fertilizer is decomposed at high temperatures, killing most of the pathogenic bacteria and eggs, reducing the incidence of diseases and insect pests; the refined organic fertilizer will not induce decomposition when it is decomposed in the soil.
(3) Beneficial bacteria are added to the bio-organic fertilizer, which reduces the incidence of diseases due to the mass effect of the bacteria. The refined organic fertilizer kills all the microorganisms inside due to high temperature drying.
(4) The content of bio-organic fertilizer has high nutrient content; the refined organic fertilizer has caused loss of nutrients due to high temperature treatment.
(5) The bio-organic fertilizer has been deodorized, has a light odor and is almost odorless; the refined organic fertilizer has not been deodorized and the odor appears when the organic fertilizer is used.
3 Differences from farmyard fertilizers:
(1) The bio-organic fertilizer is completely decomposed, and the mortality rate of eggs is above 95%; the farmyard manure is simply piled and the mortality of eggs is low.
(2) Bio-organic fertilizer is odorless; farmyard manure has a bad smell.
(3) The application of bio-organic fertilizer is convenient and uniform; the application of farmyard fertilizer is inconvenient and the application of fertilizer is uneven.
4 Difference with biological bacterial fertilizer:
(1) Bio-organic fertilizers are cheap, at around 800 yuan per ton; biological bacterial fertilizers are expensive, and they cost 10,000 yuan per ton.
(2) Bio-organic fertilizer contains functional bacteria and organic matter, which can improve the soil to promote the release of fixed nutrients from the soil. Biological bacterial fertilizer contains only functional bacteria, and promotes the use of fixed fertilizer in soil through functional bacteria.
(3) The organic matter of bio-organic fertilizer is itself an environment in which functional bacteria live. It is easy to survive after being applied to the soil, and the functional bacteria of biological bacteria may not be suitable for some soil environments.
1. Improve soil and fertility. After the organic fertilizer is applied to the soil, the organic matter can effectively improve the physicochemical status and biological characteristics of the soil, ripen the soil, enhance the ability of the soil to maintain fertilizer, supply fertilizer and buffer, and create good soil conditions for the growth of the crop.
2, increase production and improve quality. Organic fertilizers are rich in organic matter and various nutrients to provide nutrition for crops. After decomposing organic fertilizers, it provides energy and nutrients for soil microbial activities, promotes microbial activity, 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, increase the utilization of fertilizer. Organic fertilizers contain many nutrients but relatively low levels, and release slowly. Fertilizers have high nutrient content, low composition, and rapid release. The two are applied rationally and complement each other, and 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 increase fertilizer utilization.
