STUDIES REGARDING SOIL QUALITY AND ITS IMPACT ON ENVIRONMENT

Abstract

The purpose of this study is to make an analysis of the soil form the area of Agricultural Research and Development Resort Suceava, regard the content of pesticide and a risk assessment of their environmental threats. After analyzing the sample harvested from this area there were identified qualitative and quantitative the acid 2,4D and the Florasulam, compounds of the pesticide called Mustang, post emergent pesticide, used previous years in combating weeds with broad leaf from cereal crops. Studies have revealed that emphasizes the fact that samples taken from soil surface have higher concentrations both in Florasulam and 2,4D than harvested from depth, because along with the leaching of pesticides and under the action of micro-organisms in the soil, their concentration decreases.2,4D has remained in the ground less than the Florasulam which, under the action of micro-organisms or soil passes into hydroxylated derivative compound with similar structure to florasulam but with persistence and accumulation in soil.
