AGROCHEMICAL CHARACTERIZATION OF SOILS FROM OLT COUNTY
Abstract
In order to characterize from the agrochemical point of view the soils from Olt County, there were considered agrochemical studies conducted in the county by OSPA Olt in the period 2008-2012, on the entire surface of the county at all land use categories. In the period subject to the agrochemical study, soil samples were collected from agrochemicals plots with different surfaces according to usage and were analyzed: the pH, humus content, nitrogen, phosphorus and potassium. After analysis it was found that:
- Soil humus content is low and very low to cca.48% of agricultural land, requiring large expenses with additional fertilization;
-The presence of large areas of acidic soils (about 45% of agricultural land) limits yields per unit of area;
- Low and very low-supply in mobile phosphorus (cca.57% of agricultural land) limiting production in all cultures and affects crop quality.
