ASSESSMENT OF ANTI-EROSION EFFICIENCY FOR THREE CROP ROTATIONS APPLIED TO MOUNTAIN SOIL

Kazimierz Klima

 

ABSTRACT



One factor field experiment was performed from 1992 to 1996 in Czyrna near Krynica (Low Beskid). Influence of the number of days without a plant cover upon intensity of soil losses was studied for 3 four-field crop rotations at a mountain side of average 13.5% slope. The content of plants displaying high soil-protective capacities contributed increasingly into successive crop rotations. The research has led to conclusion that soil loss intensity (y) is directly proportional to the number of days (x) at which the soil remained uncovered, counted from harvesting a preceding plant to sowing a proceeding plant that has been assessed. The relationship can be described by the following a regression equation: y = 0.168x + 9.828 [kg∑ha-1∑year-1]; n = 136, Š = 0.01; r = 0.723.

Key words: anti-erosion crop rotations, soil losses, mountain slope, sheet erosion, sheet flow, erodible, erodibility.
