Abstract

The processes of rain erosion, together with the rain peculiarities, are affected by the particle resistance of the soils (to erosion) too. The present study was conducted to investigate the susceptibility of the aggregates, within different soil textures, to the RAINFALL EROSION processes. The experiments were done on thirty soil samples recognized within the scope of four different soil textures (of different replications) as based upon a completely randomized design. Ninety boxes were filled with aggregates (6- 8 mm) and exposed to simulated rainfalls for 30 minutes. Results indicated significant differences among different soil textures as regarded AGGREGATE BREAKDOWN (P< 0.001), SOIL COMPACTION (P< 0.001), and SPLASH OF SOIL PARTICLES (P<0.01). The highest AGGREGATE BREAKDOWN was observed in sandy loam textured soils, whereas the highest SOIL COMPACTION and SPLASH OF SOIL PARTICLES occurred in clay loam soils. The AGGREGATE BREAKDOWN was significantly affected by silt (r= -0.63, P<0.01), and clay particles (r= -0.70, P<0.01). Nevertheless, the SOIL COMPACTION and its splash of particles were significantly increased by silt and clay contents. Sand, contrary to other soil particles (silt and clay), had different effects on the RAINFALL EROSION processes.
