Over time the pasture grass loses vigor and yields decrease, indicating a certain degree of degeneration.
The main causes of degradation are lack of pasture maintenance and subsequent weed infestation, the choice of regionally unsuitable forage species and excessive grazing. The main purpose of this study was to evaluate the impact of different recovery managements on soil chemical properties and grass yield of a degraded pasture in Rondônia.
For this purpose, an experiment was installed in October 2001, consisting of five treatments: C = control; HA = harrowing NPK micronutrients; HE = Herbicide NK micronutrients; R =...
