Effects of storage on vis-NIR-SWIR reflectance spectra of Mombasa grass leaf samples
Tiago Rodrigues Tavares,Peterson Ricardo Fiorio,Hugo Tameirão Seixas,Amparo Cisneiros Garcia,Pedro Paulo Barros +4 more
TL;DR: In this paper, the effects of different storage methods on the spectral response of Mombasa grass leaves were evaluated: artificially refrigerated environment, (ii) humid environment, and (iii) without microenvironment control.
Journal ArticleDOI
Detection of nutritional stress in sugarcane by VIS-NIR-SWIR reflectance spectroscopy
Carlos Augusto Alves Cardoso Silva,Peterson Ricardo Fiorio,Rodnei Rizzo,Raffaella Rossetto,André Cesar Vitti,Fábio Luis Ferreira Dias,Kamilla Andrade de Oliveira,Michaela Bárbara Neto +7 more
TL;DR: In this article , the authors applied spectroradiometry techniques with hyperspectral data to identify the correlations between sugarcane leaf reflectance and the contents of Nitrogen (N), phosphorus (P), Potassium (K), Sulfur (S), Calcium (Ca) and Magnesium (Mg).
Journal ArticleDOI
Analysis of Total Soil Nutrient Content with X-ray Fluorescence Spectroscopy (XRF): Assessing Different Predictive Modeling Strategies and Auxiliary Variables
Tiago Rodrigues Tavares,Eduardo Leite de Almeida,Angela Guerrero,Peterson Ricardo Fiorio,Hudson Wallace Pereira de Carvalho +4 more
TL;DR: In this article , the performance of different predictive models, including a simple linear regression (RS), multiple linear regression, partial least squares regression (PLS), and random forest (RF) models for the prediction of Ca and K in agricultural soils, were evaluated on XRF data without (RS1) and with (RS2) Compton normalization.
Comparação entre o uso e ocupação e perda de solo, nos anos de 1995 e 2010, na microbacia hidrográfica do Ceveiro Comparison between use and occupancy and soil loss, in the years 1995 and 2010, in the Ceveiro watershed
Pedro Paulo da Silva Barros,Peterson Ricardo Fiorio,Juliano Araujo Martins,José Alexandre Melo Demattê +3 more
TL;DR: In this article, the authors evaluated soil losses between 1995 and 2010 scenarios of the Ceveiro watershed basin with the aid of USLE and reported an increase in pasture areas and a reduction in dirty pasture areas with 136,43 ha.
