How can soil compaction be improved? How to improve soil compaction quickly?

The main causes of soil compaction are the following factors.

Long-term monolithic partial application of chemical fertilizers. Ignore the use of organic fertilizers! Excessive chemical fertilizers and lack of organic fertilizers have led to a serious decline in soil organic matter!

The decline of soil organic matter causes the destruction of soil aggregate structure! The reasons for the decline of soil quality affected by excessive chemical fertilizer are as follows: organic matter, low content of organic matter, affecting the activity of microorganisms, thereby affecting the formation of soil aggregate structure, leading to soil compaction.

It also destroys the soil aggregate structure, resulting in soil compaction. Excessive application of potassium fertilizer: the potassium ion displacement in potassium fertilizer is particularly strong, which can replace the polyvalent cations that form the soil aggregate structure, while the monovalent potassium ions do not have the role of bond bridge, and the bond bridge of the soil aggregate structure is destroyed, which also destroys the aggregate structure, resulting in soil compaction.

Serious shortage of organic fertilizer input due to the extreme lack of organic fertilizer input leads to low (very) soil organic matter content and poor structure, which affects the activity of microorganisms, hinders the formation of soil aggregate structure, causes the acidity and alkalinity of soil to be too large or too small, and eventually leads to soil compaction.

Residual soil of plastic products destroys soil performance mainly in greenhouse planting, and plastic film and plastic bags are used more, if these things are not cleaned thoroughly, the residue in the soil can not be completely decomposed. It is easy to cause soil compaction!

Snowfall and drought alleviation in the northern winter wheat area "return to green water" irrigation needs to be timely.

Pay attention to the input of organic fertilizer: insist on using organic fertilizer input, slowly improve, and improve soil organic matter. So as to solve the problem of soil organic matter deficiency and compaction!

Reduce the amount of chemical fertilizer and apply fertilizer reasonably: it is best to test the soil and fertilize, what is lacking in the soil, and not waste the use of chemical fertilizer, so as to prevent chemical fertilizer residues and avoid affecting the soil structure! The most reasonable is to use organic fertilizers together.

Use soil conditioners to adjust soil pH! Soil pH refers to the pH of the soil. A pH of 7 indicates that the soil is neutral, less than 7 is acidic, and more than 7 is alkaline.

Soil conditioners are divided into acid and alkali conditioners, so choose soil conditioners according to soil conditions.

Fertilizers should be mainly organic fertilizers, and chemical fertilizers should be appropriately reduced. It is also possible to crush the straw of crops and return it directly to the field (straw cannot be burned) to increase soil fertility.

1. Increase the application of organic fertilizer and biological fertilizer with high bacterial content. 2. Reduce the use of chemical fertilizers, after a long time of chemical fertilizer use, in fact, there is no shortage of nitrogen, phosphorus and potassium in the farmland, but the compaction is not suitable for crop absorption. 3. Promote facility irrigation, and refuse flood irrigation and irrigation of polluted water sources.

4. Severe plots can be used with highly concentrated biological agents to increase the amount of beneficial microorganisms in the soil. At the same time, it can also prevent crop diseases.

1) Increase the application of organic fertilizer and insist on returning straw to the field.

2) Scientific fertilization and rational application of chemical fertilizers. According to the test of soil nutrient content, rational application of chemical fertilizers, increase the application of organic fertilizers, and improve soil structure.

3) Use large tractors to carry out subsoiling and land preparation to thicken the soil tillage layer. Mechanical subsoiling is adopted, and crop straw residues cover the surface of the land.

Once the soil is compacted, it is good to turn him over a few times with a hoe.

Soil compaction? A method of improvement that does not cost money.

Ask how to loosen the yellow mud.

Reasonable watering: Adjust the watering method, watering a small amount and multiple times, to avoid heavy rain washing away a small amount of soil.

Ask what farmyard fertilizer.

Ask questions to loosen the mud quickly.

1. Rational use of chemical fertilizers and attach importance to the use of high-quality organic fertilizers. Excessive mineral elements will lead to the formation of aggregate structure, soil compaction is caused by unreasonable fertilization, the bottom fertilizer should be based on organic fertilizer, chemical fertilizer is used less or not used, and the middle and late top dressing is mainly water-soluble fertilizer with high absorption efficiency.

2. Increase the input of beneficial bacteria. The organic fertilizer applied to the improved compacted soil needs a large number of soil microorganisms to decompose, and the supplement of beneficial microorganisms in the soil should be increased while supplementing the organic fertilizer.

3. Crushing crop straw and returning it to the field can improve the soil structure, and straw residue covering the land can reduce soil erosion.

4. Use large machinery to carry out deep ploughing and land preparation to improve the structure of the cultivated layer and the circulation of air.

5. Reduce the number of times the locomotive enters the cultivated land and prevent the land from being repeatedly crushed.

I'm a native of the city. Cold sensitivity. Someone who knows a little about the land.

Understand. If the land is annually on the fertilizer so that the land is dissolved. No floating powder, so we recommend that you be sure to apply more farm fertilizer, so that.

It can also play. Environmental performance. It's better to keep the land noisy.

Methods for rapid improvement of soil compaction:

1. Artificial loosening soil.

When the soil is compacted, the first thing we should do is to loosen the soil manually. Use a hoe or shovel to loosen the soil with a surface of 3-5cm to increase air permeability.

2. Sprinkle unleavened rapeseed cake.

After loosening the soil on the surface, sprinkle unfermented rapeseed cake powder on the surface of the soil, sprinkle a thin layer, do not sprinkle more, so as not to cause fertilizer. During the fermentation process of rapeseed cake flour, there will be many microorganisms, which can make the soil much looser. You can sprinkle once every half a month, and you can keep the soil loose several times in a row, and you can also replenish fertility for the month.

3. Surface covering.

If there is a lot of rain, or if you water frequently, the water flow is easy to cause soil compaction, and you can cover the soil surface with large pine scales, gravel, etc., blocking the impulse of the water flow, and also reducing the situation of compaction.

Hazards of soil compaction:

1. The respiration of the root system of the plant is obstructed.

In the case of soil compaction or long-term flooding, the cellular respiration of plant roots is weakened, and nutrients such as nitrogen mostly exist in an ionic state, and the absorption is mostly in the mode of active transportation, which consumes the energy produced by cell metabolism. Breathing is weakened, so the energy ** is insufficient, which affects absorption.

2. The root system of the plant cannot develop normally.

Soil aggregate structure is an important indicator of soil fertility, and the destruction of soil aggregate structure leads to the reduction of soil water retention, fertilizer retention capacity and permeability, resulting in soil compaction, and the root system of plants in this state will decline their vitality due to lack of oxygen.

3. Cause plant deficiency disease.

The symptoms of plant deficiency are not necessarily due to the lack of this element in the soil, but due to a series of problems such as soil compaction, unsuitable soil pH, or unbalanced soil moisture, which are caused by the decline of root absorption capacity.

The improvement methods of soil compaction include: artificial loosening of soil, sprinkling rapeseed cake, sprinkling gravel, etc.

1. Artificial loosening soil.

When the soil is compacted, the first thing to do is to carry out artificial loosening, and use a hoe or shovel to dig up the top layer of 3-5 cm of soil to loosen the soil, so as to increase the air permeability of the soil and promote the respiration of plant roots.

2. Sprinkle rapeseed cakes to accompany the old.

After loosening the surface of the soil, the unfermented rapeseed cake is crushed, and then sprinkled on the soil surface, sprinkled with a thin layer, so as not to cause fertilizer, rapeseed cake in the process of fermentation, will produce a lot of microorganisms, can make the soil loose.

3. Sprinkle gravel.

In the case of more rain in the summer collapse season, or often watering the soil, the water flow is easy to cause soil compaction, at this time, the soil surface can be covered with a layer of earth pine scales, gravel, etc., to block the impact of water flow, reduce the phenomenon of soil compaction.

The importance of soil for crop growth

1. Provide matrix.

Soil provides a substrate for the growth of crops, it is a loose surface layer on the surface of the lithosphere that can grow plants, it is the substrate for the life of land plants, it provides the necessary mineral elements and water for the growth of crops, and it is an important place for the exchange of materials and abilities in the ecosystem.

2. Decompose organic matter.

The soil contains a large number of microorganisms and invertebrates, in which microorganisms can decompose organic matter, so that it can be directly used by crops to provide nutrients for the growth of crops, and the earthworms in the soil can also achieve the purpose of turning the soil through physiological effects, increasing the oxygen content in the Lusheng soil.

3. Protect crops.

The soil protects the crops from external environmental factors, ensures that the root system grows in a stable state, and can also play a role in stabilizing the plants when typhoons and floods hit, so that they are not easily damaged.

Soil compaction refers to the phenomenon that the soil surface layer is damaged and the soil material is dispersed under the action of external factors such as irrigation or rainfall due to the lack of organic matter and poor structure, and the soil surface becomes hard by the cohesive force after drying.

What are the common causes of soil compaction?

1. The use of organic fertilizer is less, the organic matter in the soil is insufficient, and the physical and chemical properties deteriorate, which affects the activity of microorganisms, thereby affecting the formation of soil aggregate structure and leading to soil compaction.

2. Long-term single application of chemical fertilizer, diazonium light phosphorus and potassium fertilizer, soil organic matter declines, humus can not be replenished in time, causing soil compaction and cracking. Long-term application of ammonium sulfate is also prone to soil compaction.

3. Soil erosion caused by heavy rainfall.

After heavy rainfall, the fine soil particles in the topsoil layer are carried away, causing the soil structure to be damaged. However, clay particles and small particles are easy to form compaction after precipitation and drying up in stagnant water or slow flow rate.

Soil compaction leads to poor root development of crops and affects the growth and development of crops.

How to solve: rational use of chemical fertilizers, increase the application of microbial agents containing organic matter, supplement organic matter and beneficial bacteria, improve soil physical properties, enhance soil permeability and water retention, improve soil aggregate structure, and provide food and energy for microbial activities, this kind of microbial fertilizer uses the original bacteria stock solution fermentation, contains a variety of microbial fermentation metabolites, conditions the soil, and can maintain the root system, improve a good foundation for crop growth.

Soil compaction is an effective way to solve soil compaction by focusing on prevention and rational supplementation of organic and inorganic nutrients.

1.Tap water must be dried before use. Before watering the flowers, put the tap water in the sun for 2 days, which can volatilize the chlorine in it, and the water temperature can be raised a little, so that it will not be particularly cold. This kind of water is better for the flowers, and it is not easy to cause soil compaction.

2.When applying organic fertilizer, it must be used after it is decomposed, otherwise it is easy for the soil to be compacted and the root system is not good. It's like a flower for washing rice. If you want to bask in the sun for 2 months, you will find that the supernatant becomes transparent and clear, which is rotten. Watering the flowers with 30 times the water works best.

3.Flower pots should be replaced every 1-2 years. The repotting time should be concentrated in spring and autumn as much as possible.

These two seasons are not particularly cold or particularly hot, and it is a good time to change the pot. Try not to change the pot in the hot winter or summer. If the temperature is too low or too high, it is very dangerous for the flowers.

Summary. Extended information: The reason for soil compaction caused by regular replacement of potting soil is very simple, many flower friends think that raising flowers and watering will be fine, and changing potting and changing soil for flowers from time to time is the primary reason for soil compaction.

Therefore, the most direct and effective way to raise flowers and have potting soil compaction is to change the soil again to give the plant a new growth environment, which is conducive to the growth of the root system. When changing the potting soil, we should also choose loose and fertile humus soil, which is softer and more conducive to the healthy growth of plants.

Hello kiss, use some "small pills" In fact, to improve soil compaction, we always have caution at home to celebrate the medicine can also come in handy, vitamin C and Akuan grip spirin are good choices for bending branches.

Extended information: The reason for soil compaction caused by regular replacement of potting soil is very simple, many flower friends think that it will be fine to raise and water sensitive flowers, and changing pots and soil for flowers from time to time is the primary reason for soil compaction caused by reed branches. Therefore, the most direct and effective way to raise flowers and have potting soil compaction is to change the soil again to give the plant a new growth environment, which is conducive to the growth of the root system.

When changing the potting soil, we should also choose loose and fertile humus, which is softer and more conducive to the healthy growth of plants.

The land is compacted, and the farmhouse fertilizer mixed with people, cattle, pigs, sheep and chickens is used, and the farmhouse fertilizer is one to two thousand catties per mu, which can improve the soil and increase production and income.

Soil compaction is because it lacks nutrients and is too sticky, so you can add gluten, plant ash, broken straw, organic fertilizer, etc. to the soil, which can quickly improve the soil compaction and supplement soil nutrients, killing two birds with one stone.
