What is the main difference between microbial fertilizer and organic fertilizer

Organic fertilizers. NY-525-2012) - Industry standard.

Refers to the carbon-containing organic material that is mainly used in plants and (or) animals, after fermentation and decomposition, and its function is to improve soil fertility, provide plant nutrition, and improve crop quality. It is suitable for organic fertilizer made from livestock and poultry manure, animal and plant residues and animal and plant products as raw materials, and after fermentation and decomposition.

Bio-organic fertilizer.

NY-884-2012) - Industry standard.

It refers to a type of fertilizer with both microbial fertilizer and organic fertilizer effect, which is composed of specific functional microorganisms and animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and harmless treatment and decomposing organic fertilizer.

1) Bio-organic fertilizer has complete nutrients; There are only one or a few nutrients in fertilizers.

2) Bio-organic fertilizer can improve soil; Frequent use of chemical fertilizers can cause soil compaction.

3) Bio-organic fertilizer can improve product quality; Excessive use of chemical fertilizers leads to poor product quality.

4) Bio-organic fertilizer can improve crop rhizosphere microbiota and improve plant resistance to diseases and insects. Chemical fertilizers are crops with a single microbial community and are prone to pests and diseases.

5) Bio-organic fertilizer can promote the utilization of chemical fertilizer and improve the utilization rate of chemical fertilizer; The use of chemical fertilizers alone is easy to cause nutrient fixation and loss.

There is a complementary relationship between microbial fertilizers and fertilizers, and they can play a complementary role in each other.

1. Microbial fertilizer is the general name of biological organic fertilizer, microbial agent and compound microbial fertilizer, microbial fertilizer contains more organic matter that can promote the growth of beneficial microorganisms and improve the soil environment and traits of beneficial bacteria, which can continuously improve the soil properties after application, and provide a better growth environment for crops.

2. Chemical fertilizers are called inorganic fertilizers, and nitrogen, phosphorus, potassium and compound fertilizers are all chemical fertilizers. The nutrient content of chemical fertilizer is relatively high, and the fertilizer effect is relatively fast, most of the chemical fertilizer also has the characteristics of acid-base reaction, which does not contain organic matter, and has no improvement effect on the soil.

3. When planting crops, it is necessary to use chemical fertilizers or microbial fertilizers reasonably according to the needs of crop growth and soil moisture, or use them together, so as to ensure that the nutrients absorbed by crops are relatively balanced, and crops can grow and develop better.

4. When fertilizing crops, the appropriate application of microbial fertilizer can reduce the amount of chemical fertilizer, and the microbial fertilizer can effectively improve the utilization rate of chemical fertilizer, and the microbial fertilizer contains more strains with nitrogen fixation ability, which can convert the nitrogen in the soil into nitrogen fertilizer and play a role in promoting the early growth and development of crops.

Disadvantages of using chemical fertilizers:

1.Due to the lack of organic matter and humus, the soil aggregate structure is destroyed, resulting in soil compaction and reduced agricultural and crop yields.

2.The heavy use of chemical fertilizers reduces the quality of vegetables and fruits. Because crops not only need nitrogen, phosphorus, potassium, but also calcium, iron, zinc, selenium and other trace elements.

Moreover, the general composition of chemical fertilizer is relatively single, and the long-term use of chemical fertilizer will lead to a single nutrient content in the soil, which will easily lead to crop nutrient imbalance, thereby hindering the transformation and synthesis within the crop, resulting in a decline in crop quality, melon is not sweet, and vegetable is not fragrant.

3.The heavy use of chemical fertilizers also leads to the mass death of beneficial bacteria and earthworms in the soil.

4.Long-term inefficient application of chemical fertilizers often leads to excessive accumulation of certain elements in the soil, changes in soil physical and chemical properties, and environmental pollution.

5.Judging from the large use of chemical fertilizers now, the more chemical fertilizers are used, the lower the geographical advantage, and the more we rely on chemical fertilizers, forming a vicious circle.

Advantages of bio-fertilizer:

1.Improve the soil. (1) Through the proliferation of beneficial bacteria, a large number of beneficial bacteria form a dominant population around the roots of plants, reducing the life activities of other harmful bacteria.

2) Decompose soil organic matter, promote the formation of soil aggregates, loosen the soil through the activity of beneficial bacteria, and make the soil fertilizer retention, fertilizer supply, water retention, water supply and air permeability be well regulated. (3) Decompose pesticide residues in the soil to avoid pesticides causing harm to the next crop. It also breaks down harmful substances that are expelled through the roots during plant growth.

2.Functions of nitrogen fixation, phosphorus and potassium solution. A part of the nitrogen in the air can be metabolized by the growth and metabolism of beneficial bacteria to produce corresponding enzymes and acids, which can decompose the insoluble phosphorus and potassium fertilizers in the soil, thus becoming phosphorus and potassium fertilizers that can be absorbed by plants.

Therefore, the utilization rate of crops to fertilizer can be greatly improved and the amount of fertilizer applied can be reduced.

3.Improve crop quality. At the same time, it can promote the release of trace elements in the soil and be used by crops.

At the same time, beneficial bacteria metabolize and produce a variety of substances required by plants, such as small molecule amino acids, growth-promoting substances, vitamins, etc. 4.To achieve the effect of biological disease control, root irrigation can control the germs in the soil and spray them on the leaves to prevent the invasion of diseases.

4.Promote early crop maturity and prolong the harvest period. Because the physical and chemical properties of the soil are improved, the soil nutrients are rich and balanced, and the fertilizer in the soil can be better absorbed by crops, so it can promote early maturity of crops and prolong the harvest period.

5.When used in combination with organic fertilizer, the soil can be continuously improved, and the soil can reach the standard of producing organic crops in 2-3 years. Moreover, because the beneficial bacteria can quickly decompose organic matter for crop absorption, it overcomes the characteristics of slow organic fertilizer efficiency and low yield of organic fertilizer alone.

There is a complementary relationship between microbial fertilizers and fertilizers. The use of microbial fertilizer can improve the utilization rate of chemical fertilizer, reduce the use of chemical fertilizer, and overcome the characteristics of soil compaction, water leakage and fertilizer leakage caused by the use of chemical fertilizer alone. Next, I will analyze their relationship as follows:

1. Microbial fertilizers cannot completely replace chemical fertilizers

In the planting fields of bulk agricultural products (such as corn and wheat) that only pursue output and do not pursue the quality of agricultural products, bio-organic fertilizer is generally not suitable to completely replace chemical fertilizers. If only microbial fertilizer or organic fertilizer is used to completely replace chemical fertilizer, both product quality and yield will be pursued, and the cost of using input will be relatively high. For general bulk agricultural products that do not pursue the quality of agricultural products and only pursue yield, the cost of replacing low-cost chemical fertilizers with relatively high-cost bio-organic fertilizers is relatively high.

This kind of operation that uses only chemical fertilizers, pursues yields, and hopes for a sustained harvest of the land, can only be effective in the short term in soils rich in large amounts of organic matter. For example, the black soil in Northeast China has been using only chemical fertilizers for a long time, and at the same time burning straw, which leads to desertification of the black soil.

If the sustainable use of farmland is considered, the best way to use it is a combination of chemical fertilizers, microbial fertilizers, and organic fertilizers, especially for the planting of agricultural products with special economic benefits, such as trees, vegetables, tea, Chinese medicinal materials, etc., which is a highly targeted and economically beneficial agricultural approach. The use of microbial fertilizers not only increases yields, but also ensures the quality and quality of agricultural products.

2. Microbial fertilizer can improve the utilization rate of chemical fertilizer

Under the current planting methods, China's fertilizer utilization rate is only about 30% 35%, most of which are not absorbed by crops, or part of it is volatilized, or part of it is fixed in the soil or infiltrates into the ground with rainwater and pollutes the environment. In fertilization, organic fertilizer and microbial fertilizer as the base fertilizer, top dressing using chemical fertilizer, this chemical fertilizer combined with the application of microbial fertilizer and organic fertilizer measures, can greatly improve the utilization rate of chemical fertilizer, fertilizer utilization rate can be increased to about 70%.

3. Microbial fertilizers can reduce the use of chemical fertilizers

Improving fertilizer utilization efficiency is itself a measure to reduce the use of chemical fertilizers, and strains with nitrogen fixation ability can also reduce nitrogen in the air to fix nitrogen fertilizer in nitrogen nutrient-deficient soils, greatly reducing the use of chemical fertilizers.

Therefore, microbial fertilizer and chemical fertilizer are complementary to each other, microbial fertilizer can not only reduce the use of chemical fertilizer and improve the utilization rate of fertilizer, but also greatly improve the quality of agricultural products, therefore, the use of microbial fertilizer is a scientific and effective agricultural production measure to achieve chemical fertilizer reduction.

Microbial organic fertilizer and farmhouse fertilizer are both a kind of organic fertilizer, and now the organic fertilizer often refers to commercial organic fertilizer.

First of all, it is necessary to distinguish the difference between farmhouse fertilizer, organic fertilizer and microbial organic fertilizer.

What is farmyard fertilizer.

Farm manure includes animal manure, cake meal, plant ash, distiller's grains, green manure, household garbage, etc. Farmhouse fertilizer is a kind of fertilizer made by decomposing and fermenting organic matter, and pond sludge, crop scraps, humic acid, etc. are all counted as farmhouse fertilizer. Farm fertilizer not only contains a large number of elements of nitrogen, phosphorus and potassium, but also contains rich trace elements, farm fertilizer has long fertilizer effect and high utilization rate, but the fertilizer effect is not as fast as chemical fertilizer.

Farmhouse fertilizer can be applied for several seasons at a time, which is deeply loved by farmers, and now most of the vegetables and fruits are planted with farmhouse organic fertilizer.

Farm manure can improve the soil, increase soil organic matter, prevent soil compaction, and regulate soil pH. But the farmer must be fully fermented and rotted before it can be used, if it is not fermented and rotted, it will be applied to the soil, it will be fermented twice, there is a phenomenon of "burning seedlings" and rotten roots, and at the same time, the farmhouse fertilizer will carry the germ eggs into the soil, induce crop diseases and pests, and green manure and cake fertilizer should also be fermented and rotted before it can be used.

What is commercial organic fertilizer.

Organic fertilizer is: "the product obtained by the controlled biological decomposition of organic waste, the heat generated during the decomposition process can make the raw material harmless and stable to benefit the growth of plants, and its physical properties are completely different from the original raw material." 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".

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.

What is bio-organic fertilizer.

Bio-organic fertilizer is to add some beneficial microorganisms and fungi to organic fertilizer, and the current trading volume of this kind of fertilizer in the market is also relatively large. There are many organic fertilizer carriers of this kind of fertilizer, and the quality of this kind of fertilizer is relatively different, mainly because of the difference in the effective microbial activity quantity of microbial fungi. This kind of fertilizer also has the insufficient activity of the added microorganisms and fungi, and we must carefully identify it when choosing this kind of fertilizer.

The concept of organic fertilizer is relatively broad, and the fertilizer containing carbon source substances is collectively referred to, including cake fertilizer, compost, manure, manure, mud fertilizer, biogas fertilizer, green manure, bacterial fertilizer, etc.; From the production method, it is divided into natural organic fertilizer, organic compound fertilizer, biological organic fertilizer, etc.

Biological organic fertilizer is a kind of organic fertilizer, organic fertilizer in the process of commercial production using microbial fermentation and decomposition, can be natural fermentation or the addition of artificial strains to intervene in fermentation, to achieve the purpose of full decomposition and full sterilization.

Bio-organic fertilizer is also different from bio-fertilizer, which mainly uses organic nutrients and organic matter, and bio-organic fertilizer mainly uses strains and strains.
