Today, many measures are being taken worldwide to protect soils from heavy metals. In developed countries of the world, such as Germany, France, England, Japan, with the help of special preparations, the composition of the soil is enriched with organic substances, protecting plants from the effects of various harmful substances. Considerable work is also being carried out in Uzbekistan to disinfect agricultural soils. Samarkand State University also conducts a number of scientific studies on this topic. In particular, the Master of the Department of Soil Science and Agrotechnologies of SamSU Laylo Boylatova, under the scientific supervision of the head of the department, Professor Shodikul Kholikulov, is conducting a scientific study on the topic “Reducing the impact of harmful substances in the soil when growing organic farming products”.

    “Until now, a lot of research has been done on the use of organic fertilizers to reduce the content of heavy metals in soil and plants,” says researcher Laylo Boylatova. – Disinfectants Some substances found in the soil convert the elements cadmium, mercury, zinc and lead into a form that is insoluble in water and cannot be absorbed by plants, making it hard on the soil, but other nutrients remain in it. In this case, the preparation used is sprayed onto the soil in the form of a solution. The drug penetrates into the soil structure, neutralizing harmful substances, while other nutrients remain in it. Also, soil enrichment with organic matter, the use of mineral fertilizers, phosphate fertilizers, and liming reduce the mobility of heavy metals in the soil. A number of world scientists conducted experiments on how organic fertilizers prevent the mobility of heavy metals in the soil and their transfer to vegetation, having found that when manure, peat and green fertilizers are applied to soil heavily polluted with heavy metals, the content of heavy metals in organic matter increases. and reducing their transition to vegetation. The purpose of our study is the introduction of new methods and technologies for soil disinfection, their approbation in practice and the introduction into wide use of the most effective ones.
