Quantification and control of runoff and soil erosion on avocado orchards on ridges along steep-hillslopes
Soil erosion increases after building downward ridges along steep hillslopes, in particular during the first winter. This erosion decreases when trees grow, but runoff increases. This study presents results of erosion under five different treatments: (i) soil cover with native vegetation, (ii) bare...
