Eleven years after shrub revegetation in semiarid eroded soils. Influence in soil properties

In this sloping area, the litter generated by shrubs did not provide greater SOM at the site where it occurred, but few meters below, where it was deposited by water erosion. Comparisons between downslope and upper slope soils yielded significant differences An increase in SOM (from 1.99 to 2.75%); N (from 0.133% to 0.196%); CND (counting number drop) (from 16 to 34) and a decrease of bulk density (from 1.32 to 1.27 g cm− 3) respectively.
