How to solve the problem of high alkali content in the soil urgent

It's salty!.

Apply some organic fertilizer.

How do you raise leeches? Inside the mud? Guest soil method: It is to cover a layer of good soil on the soil.

Pour some acidic water, alum water, acidic fertilizer, and apply gypsum, but it is not clear whether these will have an effect on leeches.

Did you ask this question? I think I've seen this question before. It's best to go to the hospital to see a doctor and get a check-up so that you can prescribe the right medicine to avoid any mess. Remember to go to a regular hospital, don't go to the doctor.

Add salt....This problem is not easy to solve, it seems that it has to be slowly raised, and if you want to solve it quickly, it is estimated that it will be sour.

You can find some acidic pesticides to neutralize.

1. Use lime to neutralize acidity, apply 20 25 kg of lime per mu each time, until it is transformed into neutral or slightly acidic soil.

2. Apply green manure to increase the organic matter in the soil and improve the acidity of the soil.

3. Increase the number of irrigation times to dilute the harm of acidity to crops.

4. Increase the application of alkaline fertilizers, such as ammonium bicarbonate.

Ammonia, lime nitrogen, calcium, magnesium and phosphorus fertilizer, phosphate rock powder, plant ash.

etc., which are good for improving crop yields.

Alkaline soil improvement methods:1. Use acidic fertilizers, such as aluminum sulfate, ferrous sulfate, and sulfur powder.

Ammonium sulfate, ammonium nitrate, superphosphate, potassium dihydrogen phosphate.

Potassium sulfate, etc., directional neutralization of alkaline.

2. Apply more farm fertilizer, improve the soil, cultivate soil fertility, and enhance the affinity of the soil, such as applying well-rotted manure, peat, sawdust, edible fungus soil, etc.

3. Plant plants that are more tolerant to salt and alkali, such as rice; At the same time, reasonable field management is carried out to prevent secondary salinization.

1. The specific manifestations of all alkaline soil harm to crops are as follows:

One is to reduce the availability of soil nutrients. The availability of phosphorus in the soil is obviously affected by acidity and alkalinity, and when the pH value is exceeded, phosphoric acid and calcium or iron and aluminum form a delayed state, which reduces the effectiveness. Calcium, magnesium and potassium are easily substituted and leached in acidic soils.

The solubility of calcium and magnesium in strongly alkaline soils is low, and the effectiveness is reduced. Trace elements such as boron, manganese, and copper are greatly reduced in alkaline soils.

Second, it is not conducive to the benign development of soil and destroys soil structure. Strong alkaline soil has more hydrogen and sodium, and calcium is lacking, which makes it difficult to form a good soil structure, which is not conducive to crop growth.

The third is the activity of soil microorganisms. The most suitable pH for soil microorganisms is generally in the neutral range. Too much alkaline severely inhibits the activity of soil microorganisms, thus affecting the conversion of nitrogen and other nutrients.

Fourth, it is not conducive to the growth and development of crops. Generally, crops are best grown on neutral or near-neutral soils.

Fifth, it is easy to produce various toxic substances. After a certain amount of soluble salt in alkaline soil, it will directly affect the germination and normal growth of crops. Alkalizing soils containing more sodium carbonate are more toxic to crops.

It directly affects the growth of plants and the transformation, release and availability of soil nutrients. Generally speaking, most crops are difficult to grow normally and achieve high yields in extreme acidic and alkaline environments, in the presence of large amounts of soluble salts or in the presence of large amounts of reducing substances and other toxic substances. The strength of soil cation adsorption and exchange performance has a great impact on soil fertilizer retention performance.

There is usually a correlation between soil acidity and soil nutrient availability. For example, the effectiveness of soil phosphorus is the highest when the pH value is 6, and the effectiveness of the medium is significantly decreased when the pH value is lower or higher than 6. The availability of nutrients such as zinc, copper, manganese, iron, and boron in soil generally increases with the decrease of soil pH, but the opposite is true for molybdenum.

Too much and not enough ions in the soil can also have a negative impact on soil fertility. If calcium ion is insufficient, the stability of soil aggregates will be reduced, its structure will be destroyed, and the permeability of soil will be reduced. Too many aluminum and hydrogen ions will cause the soil to react acidically and produce aluminum ion toxicity; Too much sodium ion will cause alkaline reaction and sodium ion poisoning in the soil, which is not conducive to plant growth.

1. The availability of phosphorus in the soil is obviously affected by acidity and alkalinity, and when the pH value is higher or lower than 6, phosphoric acid and calcium or iron and aluminum form a delayed state, which reduces the effectiveness. Calcium, magnesium and potassium are easily substituted and leached in acidic soils. The solubility of calcium and magnesium in strongly alkaline soils is low, and the effectiveness is reduced.

Trace elements such as boron, manganese, and copper are greatly reduced in alkaline soils, while molybdenum forms precipitates with free iron and aluminum in strongly acidic soils, reducing their effectiveness.

2. It is not conducive to the benign development of soil and destroys soil structure. Strong acidic soils and strong alkaline soils have more hydrogen and sodium, and calcium is lacking, which makes it difficult to form a good soil structure, which is not conducive to crop growth.

3. It is not conducive to the activity of soil microorganisms. The most suitable pH for soil microorganisms is generally in the neutral range. Excessive acidity or alkaline can severely inhibit the activity of soil microorganisms, thereby affecting the conversion of nitrogen and other nutrients.

4. It is not conducive to the growth and development of crops. In general, crops are best grown in neutral or near-neutral soils, while in partially acidic or over-alkaline soils, they can cause development difficulties or no growth at all.

5. It is easy to produce various toxic substances. Soil is too acidic and prone to free AL

and organic acids, which directly harm crops. When the soluble salt in alkaline soil reaches a certain amount, it will directly affect the germination and normal growth of crops. Alkalizing soils containing more sodium carbonate are more toxic to crops.

Soil fertility is an important indicator of soil fertility, which measures the ability of the soil to provide various nutrients needed for crop growth. It is the comprehensive expression of various basic properties of soil, the most essential feature of soil that distinguishes it from the parent material and other natural bodies, and the material basis of soil as a natural resource and agricultural production materials. Soil fertility can be divided into natural fertility and artificial fertility according to its causes.

The former refers to the fertility formed under the influence of five major soil-forming factors (climate, biology, parent material, topography and age), which mainly exists in uncultivated natural soils. The latter refers to the fertility that has been exhibited over a long period of time under the influence of human farming, fertilization, irrigation and various other agricultural activities, mainly in cultivated (farmland) soils.

How do you say this, let's do it It's like when we cook, if we put too much salt, we don't eat well, and if we put less salt, we don't eat tastelessly, and plants absorb nutrients from the soil.

If the soil is alkaline, you can pour orange water on the soil, cut the orange peel into pieces, and then put it into a plastic pot and bottle to ferment, dilute it and then water the soil, you can also use rice vinegar, usually add a few drops when watering the soil, if the alkalinity of the soil is too serious, watering can not be reversed, then you need to change some acidic soil.

Treatment methods for soil alkalinity.

If your soil is severely alkaline, such as saline-alkali soil, then it is not possible to grow flowers, vegetables, and plants. Therefore, we need to improve the soil with severe alkalinity and adjust its pH so that it can be suitable for the growth of plants. So, how to deal with the soil that is too alkaline?

Water the soil with orange water.

In fact, when we water plants, we can add some things to the water, and then water the plants.

For example:Orange peel water is a particularly useful water。BecauseTangerine peel water is inherently acidic, so if you take it to water the plants, you can adjust the alkalinity.

When using orange water, the first thing to do is to leave the orange peel behind. When you eat oranges, don't throw away the orange peel.

Then leave it for and cut it into pieces. After that, it is put into a plastic pot and bottle for fermentation, and the plants are watered after the fermentation is successful.

After fermentation, the orange peel water has a very good effectHowever, it must be diluted in sufficient amount, otherwise the concentration will be too high and will have a bad effect on the plant

With rice vinegar. In fact, rice vinegar is also a thing that can be used for watering, becauseRice vinegar is inherently acidic。MoreoverIt is also not particularly acidic, so it is suitable for plants.

If you want to use rice vinegar, it is best to add two or three drops when watering, and you can't add too much.

Alkaline stool soil can be improved to be slightly better. But if the alkalinity is too severe, then there is no need to improve it. Because of the high level of reproducibility, changing the soil for plants is a particularly good method.

Change soil. If the soil used for the plants at home becomes alkaline, there is an abnormal situation. These conditions become very serious, and finally the watering does not become good, so it is recommended that you change the soil for the plants.

Sometimes the soil in your home has not been changed for a long time, and this may happen. So don't worry, just change some acidic soil.
