How to improve the soil? How can I find the right approach?

Sandy soil itself lacks fertilizer, water, organic matter, various elements, and is not easy to store liquid fertilizer. To improve the sandy soil, first of all, with the pastoral scenery or vegetable garden soil into the symmetry, can it be used for fertilizer and water storage. There are many people who think that to improve sandy soil, only need to use more organic fertilizers, and reduce the application of organic fertilizers, sandy soils can be improved.

However, many people ignore the use of organic fertilizers and the wrong way to improve them.

The traditional organic fertilizer itself is dry, and the traditional management mode of teaching fertilizer and top dressing, in the case of insufficient water flow, fertility is unable to be diluted and converted to the soil layer to absorb, and fertility and various elements, gradually volatilized in the soil, there is no progress effect is slow, the cost of input is high, this method of improving sandy soil is incorrect. The use of organic fertilizer can significantly increase the soil moisture content and improve the soil aggregate structure.

Improving soil permeability not only significantly enhances soil organic matter, but also improves water retention performance and improves the ability of fertilizer and water dredging in the middle and late stages. Generally, the more organic fertilizer is required, the faster the improvement is, and the better the soil layer characteristics. The application of organic fertilizer in small quantities and meals can reduce the outflow of chemical fertilizers, improve the use rate, and avoid the harm of soil salt industry or strong acid and alkalinization, and can meet many requirements for nutrients in the middle and late stages, so as to improve efficiency and quality.

It can also be combined with the integration of water and fertilizer application technology to promote fertilizer with water, control fertilizer, improve soil layer performance and chemical fertilizer economic benefits. In addition to the nutrients required for the growth and development of Camellia oleifera trees, the fertilizer on tea trees pays more attention to the economic benefits of fertilizer, follows the balanced fertilization standards, and avoids fertilizer deficiency and excessive fertilization of tea. That is, according to the physical and chemical properties of the tea soil, the rise of tea talent, the estimated production, the type of tea and the climate, etc., the effective fertilizer type, quantity and fertilization time are clarified, so as to save fertilizer fertility, reduce outflow, and improve the soil.

It is necessary to carry out proper deep ploughing, but also to avoid soil compaction, and to choose the right fertilizer. Bio-fertiliser can be used appropriately.

The most important thing to improve the soil is to prevent soil pollution, not to use chemical fertilizers indiscriminately, not to use pesticides, and not to discharge sewage at will.

It is definitely necessary to find the root of the problem, if you are overplanting, then you must return the straw to the field appropriately, and stop planting appropriately.

Simple ways to improve the soil are to reduce the acidity and salinity of the soil by planting crops with a high ability to absorb fertilizers, such as corn, sorghum and kale. The soil can be improved by fertilizing, applying hydrated lime to neutralize the acidity of the soil, and mixing quicklime with acidic fertilizer to facilitate the growth of crops in acidic soil.

Improve soil conditions by planting crops, such as corn, sorghum, kale, and other crops that absorb fertilizers, to reduce the salt content of the soil, and also to reduce acidity. When salt accumulation occurs in the soil, crops with high salinity tolerance such as spinach, celery, and eggplant can be planted directly.

Soil conditions can be improved by applying fertilizers. When the soil is acidified, the quicklime and acidic fertilizer are mixed and applied, which is conducive to the normal growth of crops in acidic soil, and hydrated lime can also be applied to neutralize the acidity in the soil, so as to achieve soil acid-base balance, which is conducive to the development of plant roots.

Soil conditions are improved by turning the soil regularly, usually after the crop has been harvested. When turning the soil, it is necessary to mix the lower layer of soil with less salt content with the surface soil, and apply an appropriate amount of decomposed and fermented organic fertilizer at the bottom of the soil, and when the soil salt content is high, the fertile soil can be replaced for planting.

Dilute the salt content in the soil by irrigation, generally water the surface of the soil, and you can also regularly disinfect the soil, fumigate the soil with sulfur powder, or use a diluted potassium permanganate solution to disinfect the soil, turn the bottom soil up, and place it in the sun for disinfection.
