Application prospect of attapulgite in fertilizer market of

In the early 1960s, China began to use a large amount of chemical fertilizer, which opened up the fertilizer Revolution: chemical fertilizer can intensify the fertile soil formed by traditional organic agriculture, promote agricultural production significantly, solve the problem of food shortage, and especially ensure the continuous growth of China's grain in the past decade. However, the extensive use of chemical fertilizer has serious negative effects: a large amount of soil organic matter and trace elements are consumed, the soil ecosystem is shrinking rapidly, the proportion of various nutrients is accelerating imbalance, the organic matter and mineral elements are decreasing rapidly, the soil physical and chemical properties and soil microbial flora are accelerated destruction, which leads to the decline of agricultural products quality, the pollution of farmland ecological environment and the safety of the tongue There is a lack of security, and people's livelihood and health are threatened.
 
Adding attapulgite into organic fertilizer can improve soil structure and product quality
 
One is because attapulgite has strong adsorption, ion-exchange and catalytic properties. Attapulgite organic fertilizer has unique physical and chemical properties of non-metallic minerals. It has obvious effect on supplementing beneficial trace elements, organic nutrients and water, improving fertilizer utilization rate, improving soil, and improving crop yield and quality.
 
Second, the porous channel nanostructure of attapulgite has strong adsorption, which can control and fix the nutrients in the soil, and has the ability of maintaining fertilizer and water and slow-release. It can effectively play a long-term fertilizer effect, reduce the loss of nutrient elements, balance the regulation of soil nutrients, improve fertilizer utilization rate, and prevent soil nutrient loss and barrenness.
 
Third, it can adjust the pH and has obvious fertile soil effect. It can adjust pH value, loosen and activate soil, improve hardened soil, acid soil and saline alkali soil, improve soil physical and chemical properties, and improve soil organic matter. It can increase the permeability of air and water, which is conducive to water retention and air permeability. It can increase water holding capacity and cohesiveness for sandy soil, and reduce bulk density and increase air permeability and water permeability for hardened soil. It can exchange a variety of metal ions, especially heavy metal ions. It can deal with polluted soil and water, improve the exchange capacity of soil base, and improve the acid soil.
 
Fourth, it can supplement trace elements needed by crops. Attapulgite mineral contains many beneficial elements, cell reactivating elements and other nutrients, which can quickly degrade the fertilizer damage caused by excessive fertilization and turn it into effective fertility. Long term use can conserve land, improve soil fertility, improve organic matter content, make crops grow healthily, increase yield, improve quality, and increase economic benefits, thus opening up a new way for sustainable development of agriculture.
 
Fifthly, it can degrade the chelates formed by harmful substances and trace elements, effectively absorb toxic and harmful substances in soil, such as heavy metals and radioactive elements, accelerate the speed of beneficial reaction, accelerate the degradation of harmful substances, reduce the contents of nitrate, heavy metals, pesticides, herbicides and other harmful substances in agricultural products, and improve the safety of agricultural products. Nitrate can be reduced by 20%.
 
Sixth, it can enhance the crop resistance, drought resistance, waterlogging resistance, cold resistance, premature aging resistance, lodging resistance, resistance to continuous cropping, etc., and maintain the suitable soil temperature.
 
Seventh, it can significantly improve the yield and quality of agricultural products. The fertilizer is rich in many kinds of elements, vitamins and trace elements necessary for plant growth. It can balance nutrition, increase yield, and improve color, taste and quality of crops.
 
Eighth, attapulgite organic fertilizer is pure natural, without any toxic and side effects. Using it, ecological and environmental protection, is conducive to improve the safety of agricultural products, improve the ecological environment. Large area application can improve the ecological environment of farmland, build regional planting and breeding circular ecological industrial chain, which has strategic significance for the sustainable development of regional agriculture.
