Abstract


Species of the grass (Poaceae) have been recommended in initial recovery processes. However, they need a posterior control, avoiding the competition with those of interest, especially arboreal ones In this context, the objective was to quantify the exposed substrate in a degraded area in Diamantina, Minas Gerais, by of ImageJ software, on which different methods of weeding were applied for the control of exotic grasses Urochloa decumbes (Stapf) RD, Wabster and Melinis minutiflora P. Beauv. Control of grasses was carried out by applying different methods (chemical, manual and mechanical), distributed in 4 blocks, subdivided into plots and subplots. After 100 days, by means of ImajeJ processing images, it was observed that chemical method provided the lowest exposure of the substrate with greater presence of superficial biomass, unlike the manual method, which showed less vegetation cover. It was possible to quantify the substrate exposed in an environment with grass control, allowing effective planning of recovery techniques. The use of ImageJ was efficient, representing an alternative for the substrate quantification and several studies inherent in the analysis of vegetation coverage of degraded environments.
