Bordun R. Erosional firmness of agrolandscapes in the system of soil protection contour meliorative farming in the Northeastern Forest-Steppe.

Object is the process changing of soil fertility and forming of productivity of agricultural crops by execution of activities for organization of land development and anti-erosion methods of soil cultivation. The aim is to determine soil and water protective and agro-economic efficiency of agro-technical and anti-erosion methods of land development, to develop a soil-protecting and ecologically safe technologies of growing crops in the north-eastern Forest-Steppe. Methods are fieldwork, measurement and weighing, laboratory, comparative, statistical and mathematical. Developed scientifically based recommendations for production to applying on sloping land north-eastern forest-steppe soil-protection technologies of growing crops, that provide to reduce the intensity of erosion processes of eroded chernozem in 1,5-2,0 times and provide productivity of crop rotation at the level 5,28 t/ha AU of cereal and 7.46 t/ha AU of forage crops. The main scientific results verified in production environment and implemented during 2004-2012 in State Enterprise "Experimental Farm of Institute of Agriculture of Northern East of NAAS" on total area of 457 ha, in agricultural company Ltd "Velykobudkivske" from Nedryhailivskyi district in Sumy region on area 35 ha and in agricultural farming "Demetra" from Sumy district in Sumy region on area 62 ha. Areas of use are agricultural.
