Conformidade e adequabilidade na segmentação de imagens OLI/Landsat 8-9 para mapeamento de pastagens degradadas. Author(s): SOUZA, I. C. DE; SILVEIRA, H. L. F. da; RODRIGUES, C. A. G.; FRANZIN, J. P.; RONQUIM, C. C. RESUMO: O uso do Sensoriamento Remoto para o planejamento e a tomada de decisão é cada vez mais frequente em função da grande disponibilidade de dados e de ferramentas de manipulação. No mapeamento de... ... Repository: BDPA Publication year: 2023
Regressão linear para correção de falhas da estação pluviométrica de Sorriso, MT. Author(s): CASTAGNA, D.; VENDRUSCULO, L. G.; SOUZA, A. P. de A chuva é um tipo de precipitação pluvial e um elemento climático que permite a caracterização do ambiente e aplicação em inúmeras pesquisas agrícolas e ambientais. Porém, é comum encontrar falhas em... ... Repository: BDPA Publication year: 2021
Hierarchical pedotransfer functions for predicting bulk density in Brazilian soils. Author(s): REIS, A. M. H. dos; TEIXEIRA, W. G.; FONTANA, A.; BARROS, A. H. C.; VICTORIA, D. de C.; VASQUES, G. M.; SAMUEL-ROSA, A.; OTTONI, M. V.; MONTEIRO, J. E. B. de A. Bulk density (BD) is a soil physical property used as a soil quality indicator and variations in this measurement influence soil water content and carbon stock estimates. This study aims to compile a... ... Repository: BDPA Publication year: 2024
How accurate are pedotransfer functions for bulk density for Brazilian soils? Author(s): BOSCHI, R. S.; BOCCA, F. P.; LOPES-ASSAD, M. L. R. C.; ASSAD, E. D. The aim of this study was to evaluate the predictive capability of PTFs available in the literature to estimate soil pb in different regions of Brazil, using different metrics (mean absolute error (MA... ...

Parameterization and evaluation of predictions of DSSAT/CANEGRO for Brazilian sugarcane. Author(s): MARIN, F. R.; JONES, J. W.; ROYCE, F.; SUGUITANI, C.; DONZELLI, J. L.; PALLONE FILHO, W.; NASSIF, D. S. P. 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. Author(s): REIS, A. A. dos; WERNER, J. P. S.; SILVA, B. C.; FIGUEIREDO, G. K. D. A.; ANTUNES, J. F. G.; ESQUERDO, J. C. D. M.; COUTINHO, A. C.; LAMPARELLI, R. A. C.; ROCHA, J. V.; MAGALHÃES, P. S. G. 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
Mapping soil cation exchange capacity in a semiarid region through predictive models and covariates from remote sensing data. Author(s): CHAGAS, C. da S.; CARVALHO JUNIOR, W. de; PINHEIRO, H. S. K.; XAVIER, P. A. M.; BHERING, S. B.; PEREIRA, N. R.; CALDERANO FILHO, B. Planning sustainable use of land resources requires reliable information about spatial distribution of soil physical and chemical properties related to environmental processes and ecosystemic function... ...

Improvement of clay and sand quantification based on a novel approach with a focus on multispectral satellite images. Author(s): FONGARO, C. T.; DEMATTÊ, J. A. M.; RIZZO, R.; SAFANELLI, J. L.; MENDES, W. de S.; DOTTO, A. C.; VICENTE, L. E.; FRANCESCHINI, M. H. D.; USTIN, S. L. 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
Modelling evapotranspiration by remote sensing parameters and agro-meteorological stations. Author(s): TEIXEIRA, A. H. de C. Field energy balances from irrigated and natural ecosystems, together with a net of agrometeorological stations, were used to develop a model for actual evapotranspiration (ET) quantification, based o... ...

Mapping productivity and essential biophysical parameters of cultivated tropical grasslands from sentinel-2 imagery. Author(s): CISNEROS, A.; FIORIO, P. R.; SANTOS, P. M.; PASQUALOTTO, N.; WITTENBERGHE, S. van; SILVA, G. B. S. da; NOGUEIRA, S. F. 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
