Why is it easier to improve the soil by increasing the application of organic farm fertilizer?

The main reason is that farmhouse fertilizer contains a large number of microelements, which can supplement the missing elements and nutrients in the soil, increase the content of soil substances, and improve soil quality.

Because organic farmyard fertilizer is more environmentally friendly, farmyard fertilizer is a natural fertilizer, and there are no chemical additives that are more beneficial to the soil.

Most agricultural organic fertilizers are full fertilizers, but the nutrient content is low, the fertilizer efficiency is slow, and the duration is long, that is, because the soil is easy to be improved, not because the nutrients are absorbed by the plants.

The application of chemical fertilizer and organic fertilizer should not be mixed together, organic fertilizer should be sprinkled first and then chemical fertilizer or fertilizer should be sprinkled first and then organic fertilizer, the two must be in order, and a reasonable proportion is also needed. For farmers, the most important thing to grow crops is chemical fertilizer. It can be said that the application of chemical fertilizers determines the yield of crops and directly affects the annual harvest of farmers.

However, there is still a huge difference between ordinary chemical fertilizer and organic fertilizer, not only the effect after use is obviously different, but also brings different economic benefits to farmers. Therefore, in order to give full play to the respective advantages of chemical fertilizer and organic fertilizer, the application of the two fertilizers should also be distributed scientifically and reasonably.

The different definitions of chemical fertilizers and organic fertilizers have significant functional differences. Naturally, they should also be different during use. First of all, it should be clear in the application process that it is not possible to use only organic fertilizer when fertilizing crops, and it is unrealistic and impossible to replace chemical fertilizer with organic fertilizer.

Secondly, organic fertilizers are not pollution-free。The excessive use of organic fertilizers causes no less pollution than chemical fertilizers. Organic fertilizer contamination includes excessive nitrogen and phosphorus nutrients, antibiotics, heavy metals and pathogenic bacteria.

Therefore, even organic fertilizers cannot be blindly overapplied.

Finally, neither organic nor chemical fertilizers are suitable for excessive monolithic use, as the land cannot rely solely on the return of organic matter produced per unit area to maintain and improve soil quality。If these organic substances are eventually made into organic fertilizer, it is impossible to maintain such a high yield of the land, and it will also lead to an imbalance in the fertility of the land, so organic fertilizer should be applied together with chemical fertilizers.

However, in the actual course of operation,The application of chemical fertilizer and organic fertilizer should not be mixed together, but should be sprinkled with organic fertilizer first and then chemical fertilizer or first with chemical fertilizer and then sprinkled with organic fertilizer, the two should have a certain order, and also need a reasonable proportionIn this way, you can really play the advantages of both and help improve soil fertility.

I think the two should be used in conjunction with each other to ensure that the nutrition is more adequate.

In general, it is necessary to fertilize the nutrients that the plant needs now, rather than indiscriminately.

I think this should be fertilized according to the growth of the crop and the nutrients required by the crop.

Generally, when it is just beginning to grow, it is better to use ordinary chemical fertilizers.

Chemical fertilizers mainly supplement the lack of nitrogen, phosphorus, potassium and other elements in the soil, while organic fertilizers mainly supplement the humus in the soil. However, organic fertilizers also contain a lot of nitrogen.

Therefore, when planting, it is recommended to apply organic fertilizer to the bottom fertilizer to improve the content of soil organic matter, and chemical fertilizers can be applied appropriately during the rapid growth period and flowering period of crops to improve growth efficiency, meet the elements needed for crop growth, and ensure yield.

Farm fertilizer contains a large amount of noisy organic matter, which can decompose and produce water, carbon dioxide and some inorganic salt coats (such as nitrogen, phosphorus, potassium, etc.) under the action of microorganisms. Carbon dioxide is the raw material for photosynthesis; Inorganic salts are indispensable components of plant life.

The need to use more organic fertilizer in the soil is to increase the organic matter content of the soil and form an aggregate structure in the soil. The application of organic fertilizer can improve the soil and keep it in a stable state. In some soils, there are calcium carbonate and polysaccharides, which can play a role in resistance after organic fertilizer.

The substance in the soil must be homogeneous, otherwise there will be problems when growing vegetables. If there is no way to form a stable aggregate shape in the soil, there will not be enough water. <>

If there is an opportunity, it can provide nutrients to the crop and also increase the potassium content. The increasing amount of potassium can improve the quality of the product and also expand the area of arable land. In the process of planting, it is necessary to add more organic fertilizers, which are very common in rural areas.

When using organic fertilizer, it is necessary to pay attention to the fact that it must be rotted, and it cannot be used without rotting organic fertilizer. Bugs can appear in such organic fertilizers, and these bugs may also disrupt the growth of crops. <>

Some people choose to grow sweet potatoes in rural areas, and if organic fertilizer is applied, the nutrients can be kept in a balanced state. First, it can significantly increase the yield, and secondly, the effect of fertilizer efficiency is also very high. The quality of agricultural products can be changed, and the nutrition of sweet potatoes is very high, and the size is very full.

With organic fertilizer, the soil should be loosened from time to time so that nutrients can be delivered to the individual root systems in a timely manner. When planting crops, choose to water more water to let the water and fertilizer dissolve. <>

In general, no matter what crops are planted, organic fertilizer should be added in time, and organic fertilizer can also be used as base fertilizer. The soil is fertile enough for the seeds to germinate faster and the plants that grow are very good. Organic fertilizer is closely related to the quality of cultivated soil, mainly depending on the individual's planting habits.

First, an important point in the application of organic fertilizer is to increase the organic matter in the soil. It is the main material basis of soil fertility. Organic fertilizers have important effects on soil structure, nutrients, energy, enzymes, moisture, ventilation and microbial activity.

Second, organic fertilizer contains a large number of nutrients required by plants, and has a long after-effect on the nutrients of plants. Due to the various nutrients in organic fertilizer, organic fertilizer also contains a variety of trace elements, which provides conditions for the production of high-yield, pollution-free green food. Organic fertilizer increases the content of various sugars in the soil, with sugars, organic matter releases a lot of energy in the degradation, and the growth, development and reproduction of soil microorganisms have energy.

Third, the application of organic fertilizer greatly improved the soil enzyme activity. Livestock and poultry manure contains various active enzymes secreted by animal digestive tract, as well as various enzymes produced by microorganisms, which are conducive to improving soil absorption performance, buffering performance and stress resistance. The application of organic fertilizer increases the organic colloids in the soil and cementes the soil particles.

It becomes a stable aggregate structure, improves the physical, chemical and biological properties of the soil, and improves the water retention, fertilizer retention and air permeability of the soil. Create a good soil environment for plant growth.

Fourth, organic fertilizer is decomposed and converted into various humic acid substances in the soil. Humic acid substances can promote enzyme activity, substance synthesis, transport and accumulation in plants. Humic acid is a polymer substance, which has high cation substitution amount, good complexation adsorption performance, and complexation adsorption of heavy metal ions.

It can effectively reduce the toxicity of heavy metal ions to crops and prevent them from entering the plant body.

Organic fertilizer can significantly increase the content of soil organic matter, which is conducive to maintaining the stability of soil organic matter and improving the physical and chemical properties of soil. Soil organic matter, calcium carbonate and polysaccharides had a good effect on the stability of soil structure. Organic fertilizer contains various nutrients required by crops, and the use of organic fertilizer can significantly increase the content of nutrients in the cultivated soil, especially potassium.

Because organic fertilizer can provide more nutrients for plants, and it is also easy to digest and absorb, it can promote plant growth; It can provide a variety of nutrients to the soil, improve soil structure, promote plant growth, avoid water loss, and increase soil air permeability.

Because of the continuous deterioration of China's soil environment, a large amount of nutrient organic matter in the soil is lost; Organic fertilizer is the first of soil nutrients, which can promote the growth and development of crops.

The advantages of organic fertilizer mainly include soil improvement, improving land use, reducing pollution and health risks, killing pathogenic bacteria, using organic fertilizer as breeding bedding, and inhibiting diseases.

Organic fertilizer 1, soil improvement.

Organic fertilizer is a good soil amendment. When organic fertilizer is used on farmland or degraded soils, it can increase organic matter, modify soil structure, reduce the amount of chemical fertilizers used, and can mitigate potential soil erosion.

2. Improved land use.

A considerable part of agricultural organic waste is still used in land after direct or simple treatment, although it also has fertilizer value and can play a role in improving soil quality. The use of organic fertilizer for agricultural waste has the following advantages: from the nitrogen in the waste to more stable organic nitrogen, although there is also a loss of some nitrogen, the remaining nitrogen is often not easy to be leached and volatilized; The initial carbon and nitrogen ratio of agricultural waste is high or low, and after direct application to the soil, it will lead to insufficient nitrogen or excess nitrogen in the soil, affecting crop growth, on the contrary, the carbon and nitrogen ratio of organic fertilizer after composting tends to be reasonable, which is more suitable for land use (decomposed organic fertilizer should theoretically tend to the carbon and nitrogen ratio of microbial bacteria, that is, about 16.

It is generally believed that the decrease of CN from the initial 25 30 to 15 20 indicates that the organic fertilizer has been decomposed and stabilized. PS: For every 25g of organic carbon consumed by microorganisms, they need to absorb 1g of nitrogen); The heat generated by the organic composting process reduces the number of weed seeds in the waste, mitigating the effects of weed damage.

3. Reduce the risk of pollution and odor complaints.

Organic composting can mitigate the effects of these problems. Since organic compost products are often in demand, their way out is no longer an issue, and the nature of organic compost that can be stored and treated allows it to be transported farther away than manure or other raw materials. A well-run organic composting facility is almost free of odors and flies.

In the process of urbanization and the continuous development of agriculture on a large scale, organic waste is beginning to become a burden rather than an asset. Especially for some agricultural breeding enterprises, because there is no large area of land to absorb these animal manure, the number of animals far exceeds the capacity of the land, making the manure treatment a headache.

4. Organic fertilizer is used as a substitute for breeding bedding.

Many studies have shown that powdered organic fertilizer can be used as a bedding material to replace sawdust and straw flour in farms.

From the perspective of animal welfare and improvement of the breeding environment, the bedding layer should be laid in the breeding enclosure, which is conducive to adsorbing animal excrement and reducing environmental pollution on the one hand, and provides a comfortable ground environment for animals on the other hand.

5. Organic fertilizer to reduce soil-borne diseases.

Good organic fertilizers have been found to mitigate soil-borne diseases in plants without the use of chemical control. This disease-inhibiting feature of organic fertilizers has been widely recognized and appreciated.
