Soil roughness changes of tillage systems from rainfall

Soil roughness changes of tillage systems from rainfall

Paper, American Society of Agricultural Engineers (85-2048): 20 pp

Changes in soil surface roughness were measured for three tillage systems following the application of a series of simulated rainstorms. Tillage systems were chisel, chisel + discing, and chisel + discing + do-all. Rain with storm durations of 15, 30, 45, 90, 180 and 360 min. was applied at an intensity of 50 mm/hr and at an energy rate of 0.275 kJ/msuperscript 2mm. Soil surface roughness was expressed in terms of a parameter R which integrated the effect of clod size and frequency.
