Tobiata, spreading from 50 to 90 cm distance. The rest time was 33 days after 1 day grazing time. So, the soil 53% cover, by grass occupation, rised to 89% after 11 days leaf growth and 100% after 22 days. This suggest the need of reavaluation of the rest time by buchgrasses intensively to develop, to avoid future damage to soil conservation and quali-quantitative biomass production by fragile soils.  adairy cattle  aGado Leiteiro  aPastagem  aSistema de Produção  aForage grass  aProduction systems  aSustainability  aSustentabilidade1 aPRIMAVESI, A.
