Control Techniques of Soil Fertilizer Pollution
Fertilizer is an important means of production. If it is used properly, it will have a significant effect on crops. However, if it is used improperly, it will cause soil pollution. Mainly in the increase of soil heavy metals and toxic elements, promote soil acidification, resulting in malnutrition and nitrate accumulation, soil structure destruction, and the reduction of microbial activity, etc., and bring a series of problems to the sustainable development of agriculture. Therefore, how to prevent soil fertilizer pollution is particularly important. 1Strengthening environmental awareness; 2 Increasing organic fertilizers; 3 Promoting formula fertilization and reducing blind fertilization; 4 Strengthening soil and fertilizer monitoring and management; 5 Applying chemical synergists; 6Improving fertilization methods.
specific measure:
1. Strengthen environmental awareness and strengthen monitoring and management of soil and fertilizers At present, most people have realized the potential dangers of chemical fertilizers to the soil environment and human health. In the future, we will continue to strengthen education and raise people’s awareness of environmental protection so that people will be fully aware of the seriousness of chemical fertilizer pollution and mobilize citizens to take part in actions to prevent and control soil and fertilizer pollution. ?
Organic manure is a traditional farmyard fertilizer in China, including straw, animal manure, and green manure. Application of organic fertilizer can increase soil organic matter and soil microorganisms, improve soil structure, increase soil absorption capacity, and increase soil colloid adsorption capacity of heavy metals and other toxic substances.
3, promote formula fertilization technology?
The promotion of formula fertilization technology can determine the amount of fertilizer to be applied, the type of fertilization, and the fertilization period, which will be conducive to the balanced supply of soil nutrients, reduce the waste of chemical fertilizers, and avoid pollution to the soil environment.
4. Strengthen monitoring and management of soil and fertilizer pay attention to the management of strict monitoring and inspection of pollutants in chemical fertilizers to prevent harmful substances that are brought into the soil by chemical fertilizers. Formulate the allowable amount standards for harmful substances and use laws and regulations to control chemical fertilizer pollution.
5. Apply chemical fertilizer synergist?
Fertilizer synergists are used to increase fertilizer efficiency and reduce soil contamination.
6, improve the fertilization method should be determined based on the nature of chemical fertilizers fertilization method, such as nitrogen, potassium fertilizer should be deep, phosphate fertilizer should be concentrated application or blending with organic fertilizer application.
