SOIL EROSION FROM AREA IANOVA, TIMIS COUNTY

This study focuses on an area of erosion soils developed in Timis county of North - East of Timisoara. Soil erosion phenomenon intensity over the field of Ianova area is controlled by environment factors: relief, climate (rainfall intensity and runoff), vegetation, lithological substratum and human activity. Slope erosion state on erosion classes show that more than half of slope lands are affected by moderate and strong erosion. Ecopedological indicators of chemical soil characterization present lower values while erosion degree progresses. Thus, humus cantity progressively comes down from soil weak eroded (3,90-2,82%) to soil excessive eroded (1,14%-1,11%). Nitrogen content expressed through nitrogen indicator has medium values (1,86-3,04) for weak and moderate eroded soils and small values (0,96-0,21) for excessive eroded soils. Potassium content substantially comes down from weak eroded soils (180ppm) till to those excessive eroded (132 ppm). Phosphorus content has small values for all eroded soils (4,70-2,68 ppm). For eroded fields of Ianova area we propose: antierosional developments, agropedoimprovement works, antierosional agrotechnical works.
