THE SUITABILITY OF SOILS IN THE AREA OF THE COMMUNE DIOSTI, DOLJ COUNTY, FOR DIFFERENT CROPS AND, IN PARTICULAR, FOR HORTICULTURAL PLANTS

The importance of the soil evaluation work consists in that the evaluation marks establish the uses and cultures most indicated on a certain field. The evaluation marks are variable and depend on the characteristics of the soil, the crop varieties and hybrids used, the technologies applied, etc. From the analysis of the physical, hydro-physical and chemical properties of the soils in Diosti commune, Dolj County, and their distribution by modes of use, it is found that the largest surface is suitable for arable use; the horticultural plants are suitable on a smaller surface. The productions obtained during the period when the observations were made (2015-2018) at the main horticultural plants are average or tend towards the upper part of the production recommended by the technology. In 2018, with apple tree, a production of 12.5 t / ha was obtained. In 2016 and 2017, the production was 11 t / ha. The average over the 4 years was 10.7 t / ha. The plum tree yields were between 5.5 - 7.0 t / ha. These obtained productions are due to the culture system with large distances between trees and the climatic conditions in the area but also to other factors such as not applying the phytosanitary treatments in time
