TY - JOUR T1 - Influence of mesquite control on soil erosion on a depleted range site JF - Journal of Soil and Water Conservation SP - 131 LP - 133 VL - 41 IS - 2 AU - Donald J.

Mesquite (Prosopis glandulosa) control by shredding, mechanical grubbing, vibratilling, and foliar spraying with 2, 4, 5-T + picloram reduced erosion. Plowing, disking, and seeding to kleingrass (Panicum coloratum) did not reduce erosion compared to the check. Brush control treatments removed mesquite competition, thus increasing the standing crop and cover of herbaceous plants. On the kleingrass, shred, foliar spray, mechanical grub, and check treatments, the amount of plant material protecting the soil surface was the most important variable controlling soil loss. Plant cover, standing crop, organic carbon, and total porosity all related positively to each other. As plant cover and biomass increased, organic carbon and porosity increased and erosion decreased. The absence of grazing for 3 years did not change site condition sufficiently to reduce erosion on the check. ER -
