| Summary: | against major sloughing events which occurred on the other annual soil loss predictions by RUSLE were fairly close to applied to cultivated steepland fields in Los Espabeles, burned prior to planting, and one catchment served as the burning fields prior to planting significantly (p<O.10) community of Los Espabeles near Choluteca, Honduras. During compared with mulch only. The traditional practice of conservation practices such as vetiver grass hedgerows and control with mulch only. Combining vetiver grass hedgerows Erosion associated with burning and cultivating steepland event(s) over a three-year period (1993-1995). The 0.2 ha field catchments with 60% slopes were monitored in the fields is a common problem throughout Central America. grass hedgerows reduced soil loss more than mulching alone. Honduras. The predicted annual soil losses from the two In general, both models tended to over predict. However, increased runoff as compared with mulch only. The vetiver loss, it helped protect the integrity of the steepland field losses 9 times higher than RUSLE. Both USLE and RUSLE tend losses measured at the same location for various size plots. managed the same with mulch only. During the treatment models were then compared to the observed average annual soil moderate rainfall energies. mulching and the impact associated with the traditional mulching. The Universal Soil Loss Equation (USLE) and Not only did vetiver grass form a barrier to runoff and soil period (1994-1995), one catchment combined mulch management practice of burning fields prior to planting were evaluated Quantifying the magnitude of effectiveness of soil and water Revised Universal Soil Loss Equation (RUSLE) models were significantly (p<O.10) increased soil loss as compared with soil losses from gentle to rolling slopes under low to the calibration period (1993), all three catchments were the observed annual soil losses. USLE predicted annual soil three steepland field catchments were measured for storm to over estimate on steep slopes because they are based on total nitrogen, and total phosphorus loss observations from two fields without vetiver grass. The slash & bum practice using a paired runoff catchment study design. Runoff, soil, with contour vetiver grass hedgerows, one catchment was with mulching significantly (p<O.10) reduced runoff as |
