What to do if there is excess soil fertility? The soil is poor, how to improve and increase fertilit

1. Water and dilute.

Many people after fertilizing the plants too much, the flowers and plants will appear sharply all kinds of problems, like this time what is the easiest way? That's right, it's watering and dilution.

If there is a problem like this, we can carry out secondary dilution in the later stage, that is, directly water the potting soil with large water, and then let the excess water filter out as soon as possible, so that the flowing water will leave our potting soil with some nutrients, so it can also alleviate the problem of root burning caused by excessive fertilization.

Of course, with this method, everyone's potting soil itself must be loose and permeable, so that the water inside can flow out smoothly without water accumulation and root rot.

Another important point is that the root system of the plant is relatively strong in order to do this, because the root system is stronger, so it can withstand the watering.

If the plant you maintain is weaker and the root system is relatively young, then using this method may also cause another ***, so you should be cautious when using it.

2. Clean the root system and change the soil.

Many people may feel that it is no longer appropriate to clean the root system and change the soil at this time of autumn, but if you really apply too much fertilizer to the flowers, then it is more appropriate to clean and change the soil when you weigh the two, after all, it may save the life of your flowers.

To do this, first take out the whole plant, then shake off the over-fertilized soil and replace it with some new soil.

The root system should be properly cleaned with running water, so that it can be re-potted to minimize the damage of fertilizer burning, of course, this process must be carried out in a warm and windless position with a relatively small temperature change, so as to minimize the damage to the plant, if it is too tossed, then it may aggravate its problems.

After the plant is fertilized too much, it is necessary to water some water in time to let the water dilute the fertilizer in the soil. Or take the over-fertilized plants out of the original pot; After the soil is removed, the roots of the flowers are washed.

This problem has suddenly emerged, and an expert group has begun to study it for five years, and the initial results will be effective, and in a few years, the results should also come out. Using organic fertilizers is one way to do this.

The most basic thing is to look at the color. The silt is black because it is rich in organic matter and its fertility is good; The soil color of the ridge is grayish-white, and no one will fertilize the ridge, so the soil fertility of the ridge is very poor. Therefore, the fertility of dark-colored soil is good, and the fertility of light-colored soil will be higher than that of soil bulk density; determination of soil moisture content; determination of soil organic matter; determination of soil humic acids; Determination of soil pH; Determination of soil fertility (determination of nitrogen, phosphate, potassium and trace elements);

<> determination of soil EC (electrical conductivity) values, etc. depressions are susceptible to waterlogging; Slope erosion, soil texture is too sandy or too clayey, less organic matter and mineral nutrients, shallow soil layer, and poor soil layer structure. Its basic characteristic is that the fertility factors such as fertilizer, gas, water and heat in the soil cannot meet the basic requirements of crops in the process of growth and development.

Soil testing and fertilizer distribution enterprises invite technicians to the field to conduct on-site soil testing and testing, and scientifically detect and test the content and nutrient structure ratio of 16 kinds of nutrients and organic matter such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and iron in the soil.

Generally speaking, one of the main criteria for judging the fertility of the soil is the soil method: one is to "take a look". Look at the color of the soil, and judge the soil fertility from the color.

If the soil color is darker, it is mostly black soil, meadow black soil, dark brown soil and other soil types with high fertility, and if the color is lighter, it is generally more barren soil types such as white clay soil.

To improve soil productivity, we must first understand the soil, know what is the fertile soil, and then know what are the shortcomings of the soil we cultivate, and how to improve the soil fertility and make it a fertile soil. From understanding the soil to understanding the missing factors, from conservation to improving soil fertility, the color color appears dark and dark, and these dark soil layers should reach less than 50 cm, and the soil is loose and easy to cultivate, which indicates that the soil is relatively fertile and the nutrients are more sufficient; On the contrary, the soil color is lighter, the tillage is harder and laborious, and the adhesion tool indicates that the soil fertility is poor.

1. Increase plant residues:

It includes litter, dead plant bodies and roots of various plants. This is the main organic matter of the soil in its natural state. For example, straw is returned to the field, and dead branches and leaves are turned deep into the ground and landfilled.

2. Increase animal and microbial residues

Including the remains of soil animals and non-soil animals, as well as the remains of various microorganismsThis part is relatively rare. But for primitive soils, microorganisms are the earliest forms of soil organic matter**.

3. Excretions and secretions of animals, plants and microorganisms applied to the soil

Although the amount of soil organic matter is small, it plays a very important role in the transformation of soil organic matter.

4. All kinds of organic fertilizers (green manure, compost, manure, etc.), industrial, agricultural and domestic wastewater, waste residue, etc., as well as various microbial products, organic pesticides, etc.

1. Increase the amount of organic fertilizer, such as the use of crop straw organic fertilizer, as well as high-quality commercial organic fertilizer, and can also apply high-content Bika compound live microbial fertilizer. 2. Reduce the amount of chemical fertilizer, improve farmers' understanding of the role of various fertilizers, and combine the amount of chemical fertilizer with reasonable formula fertilization in combination with crop yield and soil fertility, so as to control the amount of blind application of chemical fertilizer, but also reduce unreasonable inputs, thereby increasing economic benefits. 3. Further promote dry farming, implement sprinkler irrigation and drip irrigation, or advocate the use of more rainwater storage in summer to make full use of above-ground water.

Deep well water can also be used if conditions permit.

At present, the self-made fermented organic fertilizer is more popular with the majority of farmers. Chicken manure is the first choice for many farmers, because the organic matter content in chicken manure is very high, but the chicken manure is not fully decomposed and is used, which will also cause great harm.

Fertilize the soil a lot, don't plant first, raise the land and then plant, you can stop farming for a few months first, go to a lot of fertilizer, and let the land have vitality.

Soil fertility refers to the nutrient content and organic matter content in the soil, which plays an important role in the growth and development of plants. However, due to the influence of natural and human factors, soil fertility is lost. The following is an analysis of the causes of soil fertility loss at HKUST:

1.Soil erosion: Soil erosion refers to the erosion and movement of the soil surface by factors such as water flow, wind, gravity, etc., which causes the organic matter and nutrients in the soil to be taken away, resulting in the loss of soil fertility.

2.Soil acidification: Soil acidification refers to a decrease in the pH value of the soil, resulting in the loss of soil fertility due to the inability of nutrients in the soil to be absorbed and utilized by plants.

The causes of soil acidification include human factors and natural factors, such as excessive use of chemical fertilizers, excessive irrigation, and large emissions of industrial waste gases.

3.Over-fertilization: Over-fertilization can lead to too high concentrations of nutrients in the soil, which can lead to nutrient loss. In addition, over-fertilization can also lead to excessive salt concentrations in the soil, which can affect plant growth and development.

4.Land Reclamation: Land reclamation destroys soil structure and organic matter in the belt soil, leading to the loss of soil fertility. In addition, land reclamation can lead to problems such as soil erosion and soil erosion.

5.Soil erosion: Soil erosion refers to the erosion and movement of the soil surface by water currents, which leads to the removal of organic matter and nutrients from the soil, resulting in the loss of soil fertility.

In summary, the loss of soil fertility is the result of a combination of factors. In order to protect soil fertility, effective measures need to be taken, such as reasonable fertilization, preventing soil erosion, and maintaining vegetation cover of the land.

The more fertilizer, the more fertile the soil. Organic fertilizer refers to fertilizer containing organic matter, such as: human manure, chicken manure, cake fertilizer, etc. are organic fertilizers.

Organic fertilizers can also be made homemade, such as grass, corn stalks, etc., which are soaked, degummed, and matured in the pool. Organic fertilizers mainly contain organic matter, which is difficult to use directly. It needs to be broken down by microorganisms (because the organic matter in it provides a good living environment for microorganisms) before the nutrients in it can be absorbed by the crop.

Organic fertilizers contain a large amount of organic matter and are carriers of microorganisms, so they can regulate the pH of the soil, improve soil fertility, maintain the permeability of the soil, make the soil soft, and prevent the soil from compacting and solidifying. Secondly, it is extremely important to maintain the water holding capacity of the soil and maintain the soil temperature.

Organic fertilizer** is widely available, low cost, and contains nutrients necessary for the growth of a variety of crops, so it reduces the use of chemical fertilizers, therefore, comparatively, reduces costs and increases benefits. Due to the perennial application of chemical fertilizers, the soil structure changes, so the application of organic fertilizers will improve the soil environment. Organic fertilizers must be decomposed before use because when decomposed organic fertilizers are not applied in the soil, microorganisms continue to decompose and produce ammonia, which causes the roots to burn.

In addition, organic fertilizers contain a large number of harmful bacteria and parasites, which can easily cause plant diseases and pests and affect crop growth. Try to use organic fertilizer ditches, or dig pits, and then cover with soil. Do not use it on the ground, otherwise it will cause nutrient loss and cannot be absorbed and utilized by plants.

Organic fertilizer according to the national standard organic matter above 45 525, nitrogen, phosphorus and potassium above 5, moisture below 30% qualified products. Many commercial organic fertilizers meet national standards, but when used in soil, the effect is not as good as imagined.

The main reason is the problem of raw materials for organic fertilizers. Only raw materials that can absorb and promote the increase of soil organic matter are good raw materials, and not all raw materials can meet the requirements of the standard. Choose organic fertilizer to choose food scraps and make organic fertilizer.

The pH value of organic fertilizer is close to neutral, which is most suitable for soil, which is more conducive to root absorption and increases organic matter. It is best to make use of microbial fertilizers in organic fertilizers, so as to achieve better results.

I don't think so, if you have more fertilizer, it will lead to too many nutrients, and as a result, the soil will become very dry.

Yes, the more raw materials the more fertile it is, but this soil is not suitable for growing crops and will burn the seedlings of the crops.

Indeed, the more fat you get, the more fertile your head will be, and the yield of your crops will increase.

Of course not, if the frequency is too high, then it will lead to soil destruction. It can also lead to damage to the roots of crops.

It's easy! Poop every day on the soil you need to be fertile....

Soil fertility is the comprehensive expression of soil physical, chemical, biochemical and physicochemical properties, and it is also the essential property of soil that is different from the parent material. It includes natural fertility, artificial fertility and a combination of the two. Natural fertility is the soil fertility formed under the action of natural factors such as soil parent material, climate, biology, and topography, and is a comprehensive expression of the physical, chemical, and biological characteristics of the soil.

Its formation and development depend on the appropriateness of the quality, quantity and combination of various natural factors. Natural fertility is the product of the natural reproduction process and the basis of land productivity, which enables the spontaneous growth of natural vegetation. Artificial fertility refers to soil fertility formed through human production activities, such as tillage, fertilization, irrigation, soil improvement and other human factors.

There are many ways to maintain soil fertility:

1.Grow green manure plants (mostly legumes): Because legumes fix nitrogen in the air.

Fresh plants are turned and pressed on the spot, applied in different places, or soaked and piled to cultivate plants that are mainly used as fertilizers.

2.Apply more organic fertilizer and use inorganic fertilizer rationally.

Organic fertilizer can improve the aggregate structure of the soil, change the microbial environment in the soil, and can play a long-term role, but the use of organic fertilizer is mostly time-consuming and labor-intensive, and it is necessary to use inorganic fertilizer.

3.Crop rotation is also a very effective method, generally speaking, a piece of land with the same plants in the same season will also reduce soil fertility, effective crop rotation is also an important measure to maintain soil fertility.

4.Use soil amendments. It can effectively change the soil microenvironment and improve the water and fertilizer retention capacity of the soil.

More manure is good for the soil, and the phone bill hurts the soil.

How to improve soil fertility is a common concern of farmers, and we can rationally use land to improve soil fertility by changing farming methods, land use methods and other human efforts.

1. Increase the application of organic fertilizer.

Increase and maintain the content of soil organic fertilizer by applying manure, urine manure and compost, manure, green manure and other agricultural fertilizers with high organic matter content, and a large amount of fertilizer (river mud, grass carbon, etc.) can be applied in places where conditions permit, which has an obvious effect on improving the content of soil organic matter.

Second, straw returning to the field.

Straw returning is an effective measure to improve the soil and increase the soil production capacity. 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.

3. Reasonable crop rotation.

Reasonable crop 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 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, such as sugar beet should be rotated once every seven years, sunflowers should be rotated once every four 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, plant grass and fertilize the field.

The planting of leguminous forage grasses should be vigorously advocated to fertilize the soil and increase economic yield. At present, the forage grasses that can be planted include 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 agricultural, forestry, and pastoral land.

The development and restoration of forestry is a favorable measure to balance the ecology, improve climatic conditions, and turn a vicious circle into a virtuous circle. 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.
