 Realistic and simplified models of plant and leaf area indices for a seasonally dry tropical forest. Author(s): MIRANDA, R. de Q.; NÓBREGA, R. L. B.; MOURA, M. S. B. de; RAGHAVANE, S.; GALVÍNCIO, J. D. Leaf Area Index (LAI) models that consider all phenological stages have not been developed for the Caatinga, the largest seasonally dry tropical forest in South America. LAI models that are currently... ... |
 Author(s): EBERHARDT, I. D. R.; SCHULTZ, B.; RIZZI, R.; SANCHES, I. D.; FORMAGGIO, A. R.; ATZBERGER, C.; MELLO, M. P.; IMMITZER, M.; TRABAQUINI, K.; LUIZ, A. J. B.; FOSCHIERA, W. Abstract: The potential of optical remote sensing data to identify, map and monitor croplands is well recognized. However, clouds strongly limit the usefulness of optical imagery for these application... ... |
 Author(s): CARVALHO JUNIOR, W. de; CHAGAS, C. da S.; FERNANDES FILHO, E. I.; VIEIRA, C. A. O.; SCHAEFER, C. E. G.; BHERING, S. B.; FRANCELINO, M. R. Geomorphometric variables are applied in digital soil mapping because of their strong correlation with the disposition and distribution of pedological components of the landscapes. In this research, t... ... |
 Author(s): SILVA, M. da S.; GIONGO, V.; SILVA, V. C. da; SILVA, V. C. da; SALVIANO, A. M.; ANDRADE, E. M. de The availability of potassium (K), calcium (Ca) and magnesium (Mg) in the soil affects the nutrition and productivity of the plant cover. The Ca:Mg, Ca:K and Mg:K stoichiometric ratios indicate the nu... ... |
