People often use chemical fertilizers rationally and increase the application of organic fertilizers to improve poor soils.
1. There is a good saying about the rational use of chemical fertilizers! Chemical fertilizer is a treasure, it is essential to increase production. It is a treasure when used well, but it is very bad when used incorrectly. So from this sentence we can see that the rational use of chemical fertilizers can achieve the goal of increasing production. However, excessive use of chemical fertilizers is also very harmful to the soil.
2. Increase the supply of organic fertilizers. Soil fertility is closely related to the organic matter content of the soil, and organic fertilizers can supplement the soil with rich organic matter and nutrients. Organic fertilizer must be completely broken down to kill the eggss insects, germs, etc. contained in the raw materials. Farm manure that has not been decomposed should not be used. Organic fertilizers can gradually activate the soil and improve its fertility. Currently, the use of organic fertilizers combined with chemical fertilizers is the most ideal fertilization method.
3. Supplement beneficial bacteria. Microorganisms promote the release and chelation of trace elements in the soil through the exchange of oxygen and carbon dioxide during metabolism and the secretion of organic acids and other acidic substances, effectively breaking the soil compaction. . It can also improve soil aeration and promote the production of organic matter, humic acid and humus.
4. Apply more soil amendments. With the emergence of various problems such as soil acidification and secondary salinization, especially in areas of lightumes and greenhouse fruit trees with high economic benefits, growers are troubled by soil problems. is even more serious In recent years, soil amendments have also begun to gain popularity in these regions. Soil amendments mainly have the functions of loosening the soil, improving the structure of soil aggregates, retaining water and fertilizer, and alleviating soil acidification and salinization.
The classification of soil amendments can be roughly divided into the following categories
1 Use natural ores as raw materials: such as potassium feldspar, limestone, dolomite, wheat rice stone, zeolite, phosphate rock powder, etc.
2. Use industrial by-products, waste residues or waste liquids as raw materials: such as alkaline residues, MSG fermentation tails liquid, slagsteel, etc.
3. Using shells as raw materials: Oyster shells are mostly calcined at high temperatures. The segmented activation process of protective cooking of oyster shells developed by MARTA Co., Ltd. is currently the most effective in the use of. domestic oyster shell products. The natural characteristics of oyster shells and the technical means with the best performance.
Poor soil can be improved by the following methods:
1. Application of organic fertilizers: Organic fertilizer provides the nutrients. that your plants need and improves soil fertility. For example, farm manure, rotted compost, etc. can increase soil organic matter content, improve soil structure, and improve water and nutrient retention capabilities.
2. Application of mineral fertilizers: mineral fertilizerscan provide specific nutrients that the soil lacks, such as nitrogen, phosphorus, potassium, etc. Through the scientific and reasonable application of mineral fertilizers, soil nutrients can be replenished and soil fertility improved.
3. Irrigation Management: Poor soil is usually prone to drought and water shortage, so it is suitable for Good irrigation management is very important to improve soils. Irrigate in a timely manner to maintain soil moisture and avoid excessive drought or excess moisture that could harm the soil.
4. Soil and Water Conservation Measures: In areas with poor soils, soil erosion is a serious problem. Adopting water and soil conservation measures, such as the construction of ditches, terraces and vegetation cover, can reduce soil erosion and maintain soil fertility and stratification.
5. Application of biotechnology: Using biotechnology to improve soil is also an effective method. For example, by rationally selecting and cultivating varieties with characteristics such as salt and alkali tolerance, drought tolerance and cold tolerance, we can improve the ability of plants to adapt to poor soils. Additionally, biological methods are applied to increase the number and activity of beneficial microorganisms in the soil and promote the balance of soil microbial communities.
6. Land reclamation and reuse: For very poor soils, land reclamation and reuse may be considered. By taking steps such as soil testing and fertilizing formula, deep plowing and adding amendments, initially barren soil is improved and repaired to restore its fertility.
In short, the floorspoor can be improved through various methods such as application of organic fertilizers, application of mineral fertilizers, irrigation management, soil and water conservation measures, biotechnology applications, as well as as land rehabilitation and reuse. Comprehensive application of these measures can improve soil fertility, improve soil structure, increase water retention capacity and nutrient content, and provide a better growing environment for crop growth.
