If you want to improve the soil structure and fertility of your farm in the near future, are there a

Microbial agents.

First, the purpose of soil improvement.

Increase the content of soil organic matter, prevent soil hardening, increase the number of beneficial bacteria, inhibit harmful bacteria, regulate the soil with neutral pH value, adsorb heavy metals, improve ground temperature, improve soil properties, improve soil fertility and water and fertilizer retention capacity.

Second, the process of soil improvement.

1. Soil and water conservation stage:

In the soil and water conservation phase, engineering or biological measures are taken to control soil erosion within the permissible range. If soil erosion is not controlled, soil improvement cannot be carried out.

2. Soil improvement stage:

The purpose of the soil improvement stage is to increase the content of soil organic matter and nutrients, improve soil properties, and improve soil fertility. Soil improvement measures mainly include planting leguminous green manure or increasing organic fertilizer. When the soil is too sandy or clayey, a sand-clay mixture can be used.

Note: One of the purposes of adding organic matter to the soil is to cultivate and increase the content of beneficial microorganisms in the soil. Beneficial microorganisms can increase soil permeability, loosen soil, and reduce the solidification of phosphorus in the soil.

3. Soil improvement methods.

1. Crop rotation.

Rationally arrange the planting of different varieties of vegetables, and try to consider the family type, root depth, fertilizer absorption characteristics and the acidity and alkalinity of different vegetables.

2. Disinfect the soil regularly.

3. Improve soil texture.

Fourth, scientific fertilization.

Rational use of chemical fertilizers.

When applying chemical fertilizers, it should be determined based on the lack of fertilizers in the soil and crops. Make up for what is lacking. Excessive fertilization should not be done for the sake of yield. It is best to measure the soil and fertilize for more accurate input of nitrogen, phosphorus, and potassium.

Increase organic fertilizer input.

Soil fertility depends on the amount of organic matter in the soil. The application of organic fertilizer can supplement soil organic matter. Organic fertilizers contain a large amount of organic matter and are a place for the growth and reproduction of various microorganisms.

In addition, organic fertilizer also has a strong buffering capacity, which can prevent soil acidity changes and soil hardening caused by long-term use of chemical fertilizers, improve the stress resistance of the soil itself, and ensure a good ecological environment of the soil.

Beneficial biological agents are applied to the soil.

Through the life activities of microorganisms, the ion exchange frequency of soil aggregate structure can be increased, and the relative quality of soil can be reduced, thereby increasing the contact rate between crops and soil organic matter and improving soil structure. It can be used to improve the soil, activate the soil, and increase the number of beneficial bacteria in the soil with 2 billion live bacteria and the Ribery Yanwo microbial agent that is nutritious for the bird's nest.

Secondly, microorganisms can form metabolism through life activities, so as to effectively absorb the original harmful substances in the soil and form a new microbial system. This can improve the soil environment and reduce soil bacteria.

Related** is more reasonable and suitable for the production needs of farmers.

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.

What are the essential fertility elements for farmland? Why is that? Soil is the basis for the survival of crops.

Soil fertility determines the yield and quality of crops. Soil fertility refers to the fertility of the soil, and refers to the ability of plants to continuously supply and regulate the water, fertilizer, gas and heat required by plants during the growth process. Soil fertility is a combination of physical, chemical, and biological properties of soil.

The four factors of soil fertility include trophic factors, physical factors, chemical factors, and biological factors.

What is Soil Fertility? What are the basic fertility factors of soil? Nutrient factors Nutrient factors refer to the storage, intensity, and capacity of nutrients in the soil, which are mainly determined by the amount and composition of soil minerals and organic matter.

The ability of the soil to provide nutrients to plants is not directly determined by the storage of nutrients in the soil, but by the availability of nutrients. If the soil lacks the 17 essential elements needed for plant growth, plants cannot grow healthily. If the soil lacks organic matter, mineral elements cannot be well absorbed and utilized.

Therefore, increasing the application rate of organic fertilizer is the only way for the sustainable and efficient development of agriculture in China in the future.

Physical factorsPhysical factors refer to the soil quality, structural conditions, porosity, moisture, and temperature conditions of a material. They affect soil oxygen content, redox and aeration, thereby affecting the conversion rate and existence state of soil nutrients, affecting the nature and operation of soil moisture, and affecting the growth ability and physiological activities of plant roots. Organic matter can increase the structure of soil aggregates, can improve soil permeability and clarity, can improve the physical and chemical properties of soil, can protect water, heat preservation, gas seepage, etc., therefore, the application of chemical fertilizers must be increased at the same time.

Chemical factors are the pH of the soil, the adsorption and exchange properties of cations, the reducing substances of the soil, the salt content of the soil, and the content of other toxic substances. They directly affect plant growth and the transformation, release, and availability of soil nutrients. In general, in extremely acidic and alkaline environments, there are large amounts of toxic substances such as soluble salts or reducing substances, and most crops are difficult to grow normally and achieve high yields.

Hello dear, I am happy to answer for you: so as to improve soil fertility and improve the soil First, increase the application of organic fertilizer through the application of manure, animal manure, such as urine manure and compost, manure, green manure and other organic matter content of agricultural fertilizer to increase and maintain the content of soil organic fertilizer, where conditions can be a large amount of fertilizer (river mud, grass carbon, etc.), to improve the content of soil organic matter has an obvious effect. 2. Straw returning Straw returning is an effective measure to improve the soil and increase the production capacity of the soil.

First, the straw is applied to the soil after being piled; The other is that after the crop is harvested, the straw is chopped and sprinkled on the surface of the ground and pressed with a plow, and directly returned to the field, which can improve the physical properties of the soil, promote the formation of soil aggregate structure, increase air permeability, water permeability, and fertilizer retention capacity, thereby improving soil fertility. Third, reasonable rotation Reasonable rotation is the cultivation method of land cultivation, pay attention to two points in the rotation: one is to appropriately increase the planting area of leguminous crops, in the rotation process of about four years to plant a legume crop can increase the nitrogen content in the soil, at the same time, leguminous green manure crops after turning into the soil, a large number of roots, stems, leaves can increase soil organic matter, improve soil physical and chemical properties, improve soil fertility; Second, the planting of land-consuming crops should be controlled for many years, and beans and melon crops should not be heavy and not stubble, and should be rotated for more than five years, which is conducive to restoring soil fertility and preventing and controlling diseases.

Fourth, planting grass to fertilize the field We should vigorously advocate the planting of leguminous forage grass to fertilize the soil and increase economic output. At present, it can be planted with grass rhinoceros and alfalfa, etc., in order to improve the soil, cultivate soil fertility, and increase soil production capacity. 5. Rationally Adjust the Proportion of Farmland Destroyed, Forest, and Pastoral Land The development and restoration of forestry is a powerful measure to balance the ecology, improve climatic conditions, and turn a vicious circle into a virtuous cycle.

Rational animal husbandry development can provide a large amount of organic matter for the soil, which is a direct measure to fertilize the soil and improve crop yields. Dear The above is all I have, I hope it helps you! Have a great day!!

If the nutrients are less preserved, the fertility level will gradually decrease; When the two effects are equal, the development of soil fertility is in a state of dynamic equilibrium. Among the factors that determine fertility, weathering is extremely slow, and the way to improve fertility is mainly by increasing soil organic matter. 2. How to improve soil fertility We say that one of the bottlenecks restricting the development of agricultural dust inspection production is the serious lack of investment, of which the insufficient input of soil fertility is the most prominent aspect.

Some people say that he applies a large amount of fertilizer every year, mainly compound fertilizer with sufficient nitrogen, phosphorus and potassium content, but why is it still difficult to produce high yield and high quality? In fact, this is because of a lack of awareness of the importance of effective fertility. More input does not mean more utilization, and the fertility that can be used by fruit trees in that year can be transformed into economic benefits in that year.

For example, physiological diseases. Yellow leaf disease occurs in fruit trees with iron deficiency, and lobular disease occurs in fruit trees with zinc deficiency. However, yellow leaf disease and small leaf disease do not occur in the whole garden or tree, and are often very obvious on a large branch.

Could it be that in the same piece of land, only the diseased branch corresponds to the root soil of the sagebrush and is it quietly deficient? In fact, no, it is the lack of effective fertility of the soil that causes local nutrient deficiency. To improve effective fertility, fertilizer utilization must be considered.

Taking the three major elements as an example, the current utilization rate is quite low. The consensus view is that nitrogen fertilizer use efficiency is 30 to 35 percent, phosphate fertilizer use efficiency is 10 to 15 percent, and potassium fertilizer use efficiency is 40 to 45 percent.

However, there is also a mutual antagonism between these elements, and excessive application of phosphorus fertilizer will inhibit the absorption and utilization of nitrogen fertilizer.

In agricultural production, it is a normal natural phenomenon that soil fertility is getting lower and lower. Therefore, if you plant a piece of soil for a long time, if you plant one thing for a long time, the fertilizer used will be the same, which will aggravate the compaction. Different vegetables should be planted in turns, because the fertilizer required for each vegetable is different, for example, the first year to plant vegetables with more nitrogen, and then the second year to plant vegetables with more phosphorus.

In this way, the fertilizer received by the land will be relatively balanced.

In addition, some plants have deep roots, and some plants have shallow roots, so they can also be planted in rotations, so that they can absorb nutrients from different depths of the soil.

If a piece of soil is planted for a long time, some beneficial organisms will slowly decrease. You can often use some bacterial fertilizer, this kind of bacterial fertilizer is very helpful to increase beneficial organisms, and the more beneficial organisms, the activity of this soil will be better.

In the case of planting, it does not mean that it is enough to rely on experience alone, and sometimes it is necessary to rely on scientific methods. For example, the use of organic fertilizers is now very much promoted, and this kind of fertilizer is relatively more balanced. And before planting, the land should be turned deeply, at least 30cm.

After planting vegetables, although they should not be turned deep for fear of damaging the root system, sometimes the permeability of the soil can be improved by hoeing. You can paddle every few days, and this depth doesn't need to be very deep, about 5cm.
