The most reliable soil improvement plan, the most reasonable way according to experts

With the increasing development of science and technology and the long-term unreasonable farming habits, the environment and soil on which we live have been seriously polluted. Chemical fertilizers and pesticides were originally created to increase production and income, but in the end, due to unreasonable use, they destroyed the structural molecules of the soil, resulting in a series of problems such as soil salinization, soil acidification, and soil compaction. Crop growth was inhibited, yield and income were reduced .

In recent years, although various soil improvement methods have appeared, no matter which method is adopted, soil improvement is not an overnight thing, and it is inseparable from everyone's continuous efforts. Soil improvement is a long way to go. So, what methods can effectively improve soil? There are four general plans we are going to talk about today:

First, the rational use of chemical fertilizers

There is a saying that is good! "Chemical fertilizer is a treasure, and it is indispensable to increase production. It is a treasure if it is used well, but it is extremely difficult to use if it is not used well." Then from this sentence we can see that the rational use of chemical fertilizers can achieve the purpose of increasing production. However, the excessive use of chemical fertilizers is also very harmful to the soil. Therefore, the rational use of chemical fertilizers should pay attention to the following points:

1. When applying chemical fertilizers, it is necessary to pay attention to the lack of fertilizers in the soil and crops, what to make up for what is lacking, how much to make up for what is lacking, and not to over-fertilize for the sake of yield.

2. Under different conditions such as base fertilizer, top dressing, and spraying, the type, amount, and concentration of fertilization are also different, and farmers need to use it reasonably according to the situation.

In addition, in fact, using less chemical fertilizer can prevent the continued pollution of the soil, which is the fundamental way to solve the problem of soil improvement from the source.

The second is to increase the input of organic fertilizer

The fertility of the soil has a lot to do with the content of organic matter in the soil, and organic fertilizers can add rich organic matter and nutrients to the soil. The following points should be paid attention to when using organic fertilizers:

1. The organic fertilizer must be thoroughly decomposed to kill the eggs, germs, etc. in the raw materials. Undecomposed farmyard manure should not be used.

2. It is necessary to choose organic fertilizers from regular manufacturers, or use probiotics such as gold to ferment organic fertilizers independently to prevent bad manufacturers from using raw materials such as heavy metals to produce organic fertilizers.

3. When self-fermenting organic fertilizers, pay attention to the non-toxic and harmless fermentation raw materials. Raw materials containing heavy metals and antibiotic residues are not suitable for fermenting organic fertilizers, which are easy to cause secondary pollution to the soil.

Organic fertilizer can gradually activate the soil and improve soil fertility. At present, the use of organic fertilizer and chemical fertilizer is the most ideal fertilization method!

The third is to supplement beneficial bacteria (microbial agents)

Fourth, appropriate use of soil conditioners

The main indicator of soil fertility is the content of soil organic matter. Once soil organic matter is lacking, the beneficial microbial flora of the soil will be unbalanced. Microorganisms promote the decomposition and transformation of soil organic matter and nutrient elements. The relationship between the two can be described as "lips die and teeth are cold".

In addition, organic fertilizers provide carbon nutrition for crops. It is understood that most growers are aware of the benefits of using organic fertilizers. In their words, "using organic fertilizers will make the land stronger". Since organic fertilizers are so important, why do growers not use them, or don't invest enough?

1. Some growers do not have enough awareness of organic fertilizers and do not understand the importance of organic fertilizers to soil fertility;

2. Organic fertilizers represented by traditional soil fertilizers and livestock manures are not very convenient to collect raw materials. It is difficult for farmers to ferment and decompose well, and the production is more troublesome. Modern people are relatively lazy, and naturally they are too lazy to use them. ;

3. The emergence of commercialized organic fertilizers has greatly facilitated farmers, but the disadvantage is that the cost of use is too high, the cost performance is unreasonable, and the amount invested by farmers is far from meeting the actual needs.
