Indicators In Monitoring Of Anthropogenous Influences
|
At present, soil pollution of ecosystems with fertilizers and pesticides has become global. Their entry into the soil in large quantities primarily affects the biological properties of the soil. Many authors show the destructive effect of fertilizers and chemical pesticides on soil biota. Many researchers, both in our country and abroad, were involved in the problem of the effect of chemicalization on the biological activity of the soil. Similar studies were conducted in the Republic of Kazakhstan, but in most cases they were fragmentary. The purpose of our research is to study the effect of pesticides and fertilizers on biological activity and trace elements for the use of these indicators in monitoring anthropogenic influences in the system of modern farming of the irrigation zone and the bogs of the southeast of Kazakhstan. In accordance with this goal, the following tasks will be accomplished: To determine the effect of fertilizers and pesticides on the biological activity of soils in the system of modern farming in the irrigation zone and the bogs of southeast Kazakhstan; To study the effect of pesticides and fertilizers on the humus state, the content of nitrogen, phosphorus, potassium and trace elements available for plants in the soil for use in monitoring anthropogenic impacts; To determine the dependence of the change in biological activity on the nature of the pesticide, its content in the soil of the studied ecosystems; With the help of a set of indicators to develop the most effective way to diagnose different levels of soil contamination with fertilizers and pesticides affecting the biological activity of soil in the irrigation zone and the bogs of southeast Kazakhstan Over the past 10-12 years, the use of fertilizers and pesticides has decreased significantly, while the decline in crop yields has been less pronounced and even in certain favorable years, an increase in the yield of cereals has been observed.
