Journal ArticleDOI
Visible-NIR reflectance: a new approach on soil evaluation
José Alexandre Melo Demattê,Rogério Costa Campos,Marcelo Corrêa Alves,Peterson Ricardo Fiorio,Marcos Rafael Nanni +4 more
TL;DR: In this paper, a spectral reflectance (SR)-based methodology was developed to evaluate soil types and soil tillage systems, which can be used as a methodology to assist soil surveys.
Journal ArticleDOI
Determining soil water status and other soil characteristics by spectral proximal sensing
José Alexandre Melo Demattê,Antônio Amador Sousa,Marcelo Corrêa Alves,Marcos Rafael Nanni,Peterson Ricardo Fiorio,Rogério Costa Campos +5 more
TL;DR: In this paper, the authors evaluated spectral data of wet and dry tropical Brazilian soils with different hydration and determined a method to identify soil mineralogy, to evaluate clay minerals at different moisture stages and their relationship with soil minerals, and to determine a model to estimate soil moisture using spectral data measured in the laboratory by a spectroradiometer.
Journal ArticleDOI
Rice Water Use Efficiency and Yield under Continuous and Intermittent Irrigation
Luis Antonio de Avila,Luiz Fernando Dias Martini,Rafael Friguetto Mezzomo,João Paulo Refatti,Rogério Costa Campos,Diogo Machado Cezimbra,S.L.O. Machado,Joseph H. Massey,Reimar Carlesso,Enio Marchesan +9 more
Journal ArticleDOI
Soil density evaluated by spectral reflectance as an evidence of compaction effects
José Alexandre Melo Demattê,Marcos Rafael Nanni,A.P. da Silva,J. F. de Melo Filho,W. C. Dos Santos,Rogério Costa Campos +5 more
TL;DR: In this article, the spectral reflectance of two soils: a Typic Quartzpisament (TQ) and a Rhodic Paleudalf (RP) was evaluated using a laboratory spectroradiometer between 450 and 2500 nm.
Journal ArticleDOI
Cor do solo: uma abordagem da forma convencional de obtenção em oposição à automatização do método para fins de classificação de solos
TL;DR: In this paper, a comparison of the conventional soil color determination with the colormeter method to evaluate possible implications in soil classification is made, where five soil scientists were invited to determine the hue of 80 soil samples by comparison with the Munsell color chart.
