Grama Rhodes is a tropical pasture employed in several regions of NOA.The deterioration of grass pasture are associated to reduced availability of nitrogen in the soil under permanent stands of grass ( Myers et al,1991).Cultivation can stimulate the production of nitrogen compounds which are available to plant roots but in long term increase tillage diminished the capacity of soil to immobilize and conserve mineral nitrogen.Are unknown,in our region,the effect of interval implements applied on pasture and weed production,information reported here.
