Prediction of topsoil texture through regression trees and multiple linear regressions. Author(s): CARVALHO JUNIOR, W. de; CHAGAS, C. da S. Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil p... ... Repository: BDPA Publication year: 2018
Predicting bulk density in Brazilian soils for carbon stocks calculation: a comparative study of multiple linear regression and Random Forest models using continuous and categorical variables. Author(s): VAZ, C. M. P.; MARTIN NETO, L.; COSTA, F. de S.; PERINA, F. J. The present study aims to develop pedotransfer functions for estimating ?b using stepwise multiple linear regression applied to soil properties from available databases, which are considered suitable... ...

Prediction of mineral soil fraction through regressions trees and multiple (linear) regressions. Author(s): CARVALHO JUNIOR, W. de; CHAGAS, C. da S. Repository: BDPA Publication year: 2015
Soil chemical attributes relationships around the Araucaria Angustifolia trees in agroforestry systems. Author(s): GOMES, J. B. V.; BOTOSSO, P. C. This work aimed to understand the relationships between araucaria trees and some abiotic factors (soil type, soil organic C and soil nutrient supply) in agroforestry systems (AFS). Soils of two produc... ... Repository: BDPA Publication year: 2023
Water stress in modern upland rice cultivars: a multivariate study between physiological traits and yield. Author(s): HEINEMANN, A. B. Water stress negatively affects upland rice production. The objective of this study was to identify physiological traits that could depict yield responses under water stress conditions. Three modern u... ... Repository: BDPA Publication year: 2023
Evaluation of statistical and geostatistical models of difgital soil properties mapping in tropical mountain regions. Author(s): CARVALHO JUNIOR, W. de; CHAGAS, C. da S.; CALDERANO FILHO, B.; BHERING, S. B. As propriedades dos solos têm grande impacto sobre aspectos econômicos e ambientais da produção agropecuária. As relações quantitativas entre as propriedades dos solos e os fatores que condicionam sua... ... Repository: BDPA Publication year: 2014
Modelo matemático para estimativa da temperatura média diária do ar no Estado de Goiás. Author(s): ANTONINI, J. C. dos A.; SANO, E. E. O objetivo deste trabalho foi desenvolver um modelo matemático de estimativa da temperatura média diária do ar no Estado de Goiás, que considera simultaneamente as variações espacial e temporal. O mod... ... Repository: BDPA Publication year: 2009
Modelos empíricos para estimar o acúmulo de matéria seca de capim-marandu com variáveis agrometeorológicas. Author(s): SANTOS, P. M.; PEZZOPANE, J. R. M.; OLIVEIRA, P. P. A. O objetivo deste estudo foi testar modelos empíricos de regressão linear, para a predição do acúmulo de matéria seca (TAMS) de Urochloa brizantha cv. Marandu, em função de variáveis agrometeorológicas... ... Repository: BDPA Publication year: 2011
Prediction statistical model for soil organic carbon mapping in crop areas using the Landsat/OLI sensor. Author(s): VICENTE, L. E.; LOEBMANN, D. G. dos S. W.; ARAUJO, L. S. de; MANZATTO, C. V. Abstract: The quantification of soil organic carbon (SOC) is essential to agriculture and sustainable use of the land. However, there are difficulties to estimate it in large areas due to high cost of... ... Repository: BDPA Publication year: 2019
Chemical composition and energy yield of elephant-grass biomass as function of five different production ages. Author(s): FREITAS, R. S.; BARBÉ, T. da C.; DAHER, R. F.; VIDAL, A. K. F.; STIDA, W. F.; SILVA, V. B. da; MENEZES, B. R. da S.; PEREIRA, A. V. Abstract Elephant grass has high biomass production, with qualities suitable for conversion into bioenergy, but has long been used exclusively for animal feed and only in recent years has it become an... ...
