What are the best ways to enhance soil fertility in long term dry soils?

Due to the different climates of each place, some places will have plenty of rain, while others will be dry. For long-term arid soils, soil fertility must be enhanced if crops are to be grown. In general, if you want to enhance soil fertility, you will use two methods.

The first method should be known to everyone, which is to increase organic fertilizer, and the second method is to plant plants and trees. I believe many people have seen such a scene, that is, people will use manure to water vegetables, because manure can improve the organic content of the soil. In addition, the soil is also very fertile in areas where vegetation is abundant, and both methods are very effective in enhancing soil fertility.

1. Increase organic fertilizer.

For long-term arid soils, be sure to increase organic fertilizer. In the early stage, irrigation with water and then organic fertilizer can be used to enrich the soil to a certain extent. Although organic fertilizer can make the soil fertile, it is necessary to pay attention to the amount, and if you use too much, it will also cause soil problems.

The specific amount is determined according to the specific problems of the soil, and it is necessary to grasp a degree. There are also many organic fertilizers on the market, which can be selected in a targeted manner.

2. Plant grass and trees.

In life, we often see that arid soils are basically barren, while where there are lush vegetation, the soil must be very fertile. If a soil that has been dry for a long time can improve soil fertility, the second effective way is to plant grass and trees. Although planting plants and trees can lead to fertile soil, it also depends on what kind of plants and trees are planted.

Typically, legumes and forages are planted, both of which increase the productivity of the soil and prevent diseases. Of course, you can also plant some other plants and trees, but the best results are legumes and pastures. If you feel that just planting pasture and legumes is too monotonous, you can use some other plants and trees.

To sum up, both methods are very effective. For arid soils, one of these methods can be selected and implemented according to the local climate.

The best way is to fertilize the soil, strengthen the planting of the soil, strengthen the adjustment of the soil, adjust the pH degree of the soil, monitor the soil, and adjust the state of the soil.

Be sure to water and fertilize in time, it is best to choose biological fertilizer, you can also choose organic fertilizer, it is best to choose compound fertilizer, and pay attention to the burning of straw.

Dry land can be counterproductive by fertilizing the soil in advance. Pay attention to local conditions and cultivate suitable crops. This allows the soil to slowly regain a certain fertility.

Increasing organic fertilizer, planting plants and trees, watering more, fertilizing more, turning the soil more, and other methods can enhance the fertility of the soil.

First, increase the application of organic fertilizer, manure, human and animal urine fertilizer, and compost.

Wet manure, green manure.

and other agricultural fertilizers with high organic matter content, which can increase and maintain the organic fertilizer content of the soil. Where conditions permit, a large amount of fertilization (river mud, peat.

Wait. ) can be applied, and the effect on increasing soil organic matter content is obvious. Second, straw is returned to the field.

Straw returning is an effective measure to improve soil and soil productivity. First, put the straw in the soil after composting; The other is that after the crops are harvested, the straw is chopped and sprinkled on the surface, and then ploughed with a plow and returned directly to the field. This improves 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. Thirdly, reasonable rotation is a farming method. There are two points to pay attention to in crop rotation: one is to appropriately increase legumes.

The planting area, planting leguminous plants for about four years in the rotation process can increase the nitrogen content in the soil, while a large number of leguminous roots, stems and leaves can increase soil organic matter, improve soil physical and chemical properties, and improve soil fertility. Second, the planting of soil-consuming crops should be controlled, and beans and melon crops should be rotated for more than 5 years, which is conducive to restoring soil fertility and preventing diseases. 4.

Grass planting and fertilization of fields should be strongly promoted to plant leguminous forage grasses to improve soil fertility and increase economic output. At present, osmanthus and alfalfa can be planted to improve the soil, fertilize the soil and improve soil productivity. 5. Rationally adjust the proportion of land used for agriculture, forestry and animal husbandry.

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 development of animal husbandry can provide a large amount of organic matter for the soil, which is a direct measure to improve soil fertility and increase crop yield.

Soil fertility is the ability of the soil to provide and coordinate nutrient and environmental conditions for plant 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.

The combination of land use and land cultivation, and the combination of preventing fertility decline and soil treatment are the basic principles for maintaining and improving the level of soil fertility. Specific measures include the application of organic fertilizers, the planting of green manure and the rational application of chemical fertilizers, so as to contribute not only to the high yield of current crops, but also to the restoration and improvement of soil fertility.

For some low-yielding soils (acidic, alkaline and saline), chemical amendments and irrigation should be used to improve the fertility level by removing obstacles. In addition, reasonable tillage and crop rotation should be carried out to regulate nutrients and water in the soil and prevent certain nutrient deficits and water vapor imbalances.

First of all, it is necessary to improve the quality of the soil, turn the soil several times, and carefully remove sand, stones, and rubble from the soil. It is best to choose loam, if it is sandy soil, water and fertilizer are easy to lose, you should try to add loam and organic fertilizer to it, and add humus. To determine the acidity and alkalinity of the soil, if the soil is more acidic, balanced fertilization, to meet the needs of crops for fertilizer and water, including the balanced use of organic fertilizer, bacterial fertilizer, nitrogen, phosphorus and potassium, trace elements and other nutrients, especially can not be used alone, nitrogen, phosphorus and potassium fertilizer, easy to lead to soil compaction, acidification, reduce soil fertility.

Supplementary application of biophysical fertilizer: let the organic matter in the soil fully activate, decompose, and release fertility Limit the use of chemical fertilizers: prevent soil compaction and the loss and solidification of effective fertilizer elements, thereby affecting the fertilizer utilization rate Scientific and reasonable fertilization:

Soil testing formula can be used for fertilization, grasp the principle of bucket short board effect, and fully and rationally use to maintain or rebuild a good soil structure. The soil should maintain a certain thickness, pay attention to controlling soil erosion, choose the appropriate cultivation period, generally the water content is less than 70% of the water holding capacity in the field, and higher than the withering water content, and strengthen the meticulousness of land preparation.

The most effective way to fertilize the soil is to fallow and increase organic matter. The farmer's harvesting process is almost predatory production, and the harvest process also pulls the crop straw out of the arable land. The decrease of organic matter will inevitably lead to the reduction of the reproduction and production of soil microorganisms, the decrease of soil fertility and soil compaction.

In places where conditions permit, a large number of fertilizers such as river mud and grass peats can be applied to prevent soil compaction, and it also has obvious effects on improving soil organic matter content. In addition, it is best to use rotation tillage or fallow for a period of time, which is also helpful for soil fertility restoration.

Look at the penetration of water after watering. We poured water into the vegetable field and found that the water penetrated into the soil, and when the soil was very dry, we could hear the sound of the soil absorbing water; If you pour water on the lawn or on the ridge, the water will either not penetrate or will flow down the cracked ditch.

I think the best way to improve soil fertility in a long-term dry soil is to use high-quality fertilizer in a timely manner, fertilize it, and irrigate it with plenty of water.

If you want to increase the fertility of the soil if you want to improve the fertility of the soil for a long time, then I recommend that you water it more often, because if there is a sudden shortage of water, its fertility will decrease.

The amount of fertilizer applied at one time should not be too large. If the amount of fertilizer applied at one time is large during drought, it is easy to wash away the fertilizer when it encounters heavy rain after drought. This will not only cause economic losses to farmers, but also pollute the environment.

The fertilizer is applied deeply, and the fertilizer is pressed with water. In drought conditions, if fertilizer is applied only to the surface, the fertilizer is volatile. If there is a flood after a drought, it is easy to be washed away by the rain.

Therefore, chemical fertilizer should be applied as deep as possible, and irrigation and pressure fertilizer should be selected to maintain fertilizer efficiency after application.

1. Rational use of chemical fertilizers; When applying chemical fertilizers, it is necessary to pay attention to the lack of fertilizer in the soil and crops, what is missing, how much is missing, and how much is missing, and can not be over-fertilized for the yield. It is best to be able to test the soil and fertilize, so that the nitrogen, phosphorus and potassium can be more accurately inputted.

2. Increase the input of organic fertilizer. The fertility of the soil depends on the content of organic matter in the soil, and the application of organic fertilizer can supplement the soil organic matter. Organic fertilizers contain a lot of organic matter and are where various microorganisms grow and breed.

According to the study, the application of organic fertilizer in deep tillage combined with organic fertilizer increased the soil nitrogen-fixing bacteria by nearly double, the fibrolytic bacteria increased by nearly 2 times, and other microbial communities also increased significantly, so the application of organic fertilizer could greatly promote the maturation process of the newly reclaimed land. Organic fertilizer has a strong cation substitution ability, which can absorb more nutrients such as potassium, ammonium, magnesium, zinc, etc., prevent leaching and improve soil fertilizer retention capacity. In addition, organic fertilizer also has a strong buffering capacity, which can prevent soil acidity changes and soil compaction caused by long-term application of chemical fertilizers, improve the stress resistance of the soil itself, and ensure a good ecological environment of the soil.

3. The application of beneficial biological bacteria fertilizer to the soil can increase the ion exchange frequency of soil aggregate structure and reduce the relative quality of soil through the life activities of microorganisms, thereby increasing the contact rate between crops and soil organic matter and improving the soil structure. 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 improves the soil environment and reduces soil pathogens.

4. Increase the application of soil conditioner. Soil conditioners mainly have the special effect of loosening soil, improving soil aggregate structure, and adjusting soil pH! Although soil conditioners have an improvement and conditioning effect on the soil, we must understand what kind of soil it is for when selecting, some are for alkaline soil, some are for acidic soil, and the dosage should be reasonably grasped.

What do you think is the best way to enhance soil fertility? Why?

In fact, this problem is the same kind of problem as the question of "what can be done to quickly improve the soil quality" by the former frontier dragon. All of them are due to the extensive use of chemical fertilizers, predatory planting, etc., resulting in poor soil quality and reduced fertility. So how to improve soil fertility?

Weilong believes that improving soil fertility, as a farmer, can be solved gradually within the scope of his own ability.

The first is reasonable fertilization. It is according to the law of fertilizer for planting crops, take the method of combining organic fertilizer and compound fertilizer, try to avoid the bad practice of using only chemical fertilizer without organic fertilizer, if there is a farm soil miscellaneous fertilizer, it is better to gradually reduce the use of chemical fertilizer and increase the use of organic fertilizer.

The second is crop rotation and fallow. The land, like people, needs to change its tastes and rest, and it is not just about eating the same things, and it is not possible to work all the time. After the wheat is harvested, our farmers have to plough the land and dry it for several months before sowing the wheat.

After a few years of wheat planting, the stubble should be planted and other crops such as corn or peanuts should be planted, so that the land can have a time to recuperate.

The third is to regularly carry out deep ploughing of the soil. In general, the field can be dried by turning the soil deep after each crop is harvested. In this way, the soil can be activated, the aggregate structure of the soil can be improved, the soil can be loose and breathable, and the ability to retain water and fertilizer can be improved, which is conducive to the growth and reproduction of microorganisms in the soil and the growth of crops.

Fourth, straw returning to the field and planting green manure. Due to the relatively small amount of farm manure now, the method of returning crop straw to the field can be adopted to increase the organic matter and humus of the soil. That is, do not return too much straw to the field, and do not return to the field continuously.

At the same time, the method of planting green manure can also be adopted, which has a good effect on improving soil organic matter and fertilizing the land.

I think the best way to enhance soil fertility is to fertilize, which is rich in nutrients. It can enhance the nutrients of the soil.

I think the best way to improve soil fertility is to apply fertilizer, because this will increase soil fertility in a short period of time.

It is necessary to ensure that the bottom fertilizer is sufficient, to water and fertilize in time, and to loosen the soil in time, and to place some earthworms in the soil, to kill insects and weeds in time, and ensure ventilation.

It is necessary to apply fertilizer regularly, to grasp the composition of fertilizer, but also to grasp the concentration of fertilizer. This is the safest, does not cause serious consequences, and the results are very fast.
