Parameterization and evaluation of predictions of DSSAT/CANEGRO for Brazilian sugarcane. The DSSAT/CANEGRO model was parameterized and its predictions evaluated using data from five sugarcane experiments conducted in Southern Brazil. Some parameters whose values were either directly measu... ... Repository: BDPA Publication year: 2011
Monitoring pasture aboveground biomass and canopy height in an integrated crop-livestock system using textural information from PlanetScope imagery. Abstract: Fast and accurate quantification of the available pasture biomass is essential to support grazing management decisions in intensively managed fields. The increasing temporal and spatial reso... ... Repository: BDPA Publication year: 2020
Improvement of clay and sand quantification based on a novel approach with a focus on multispectral satellite images. Abstract: Soil mapping demands large-scale surveys that are costly and time consuming. It is necessary to identify strategies with reduced costs to obtain detailed information for soil mapping. We aim... ... Repository: BDPA Publication year: 2018
Mapping productivity and essential biophysical parameters of cultivated tropical grasslands from sentinel-2 imagery. Abstract: Nitrogen (N) is the main nutrient element that maintains productivity in forages; it is inextricably linked to dry matter increase and plant support capacity. In recent years, high spectral... ... Repository: BDPA Publication year: 2020
