The importance of the soil environment for the growth of crops is not to mention, but the soil fertilization itself is an important weapon for farmers to increase their income, but the soil structure is destroyed due to unreasonable operation. Unfavorable phenomena such as soil compaction and soil acidification often occur, which leads to limited crop yields and ultimately affects farmers' planting income. Therefore, soil improvement is not a problem. So what is the most effective way to improve the soil? Let's take a look.
Ways to improve the soil
1. Rational use of chemical fertilizers
Reasonable is to determine according to the actual soil conditions and the growth of the crops, to make up for missing traps, not to fertilize excessively for production, or to reduce fertilization in order to reduce costs. It is best to be able to do soil testing and fertilization so that NPK can be invested more accurately.
2. Increase the investment of organic fertilizer
In general, farmers use inorganic fertilizers to fertilize crops. The soil will be knotted due to lack of organic matter for many years, and the supplement of organic fertilizers can solve this problem. It is reported that the deep soil cultivation combined with the application of organic fertilizer can increase the nitrogen-fixing bacteria content in the soil nearly doubled, and other microbial flora also increases significantly, and the effect of nitrogen-fixing bacteria is obviously to convert the nitrogen molecules in the atmosphere into crop growth. The nitrogen required to provide nutrients for the crop.
In addition, organic fertilizers have better nutrient absorption capacity, and can be well preserved for potassium, ammonium, magnesium and other elements to prevent loss. Not only that, organic fertilizer also has a strong buffer capacity, which can improve the soil's own resistance and ensure a good ecological environment.
3. Increase soil conditioner application
Soil conditioners mainly have loose soil, improve soil aggregate structure and regulate soil pH. Although soil conditioners have improved and conditioning effects on soil, it is necessary to know which type of soil to use when selecting. Corresponding to acid and alkali, and the amount of use should be reasonable, and excessive use may cause other side effects.
A small flaw in the improved soil: "rice shell + straw"
Rice husk is a combination of cellulose and silicon with high nitrogen to carbon ratio, so it is not easy to rot; while straw also contains higher cellulose, which can promote the formation of soil aggregate structure. These high celluloses absorb nitrogen from the soil during decay. For orchards with high levels of effective nitrogen, they are the best way to reduce eutrophication and are very effective for soil improvement.
The above is an introduction to the improvement of the soil. In general, the growth of crops and the soil have this inseparable relationship. Usually we must eliminate the excessive fertilizer, the bad habit of excessive pesticides, and the pure land of crops.
