Proximal soil sensing platform for effective mapping of soil attributes in Brazil. Author(s): OLIVEIRA, R. P. de; VASQUES, G. de M.; TAVARES, S. R. de L.; HERNANI, L. C.; BACA, J. F. M.; COELHO, M. R. Sustainable management of agricultural lands requires detailed information on soil properties. Although the literature has shown the potential of PSS data integration to predict spatial variations of... ... Repository: BDPA Publication year: 2019
A machine learning framework to predict nutrient content in valencia-orange leaf hyperspectral measurements. Author(s): JORGE, L. A. de C. This paper presents a framework based on machine learning algorithms to predict nutrient content in leaf hyperspectral measurements. This is the first approach to evaluate macro- and micronutrient con... ... Repository: BDPA Publication year: 2020
Spatial analysis of erosive processes in plateaus and depressions of the Upper Paraguai river basin. Author(s): SILVA, J. dos S. V. da Natural characteristics may contribute to the erosion of the soil and to environmental imbalances, and in most cases, they initiate the imbalances that will be exacerbated by human activities. The pre... ... Repository: BDPA Publication year: 2017
Análises físico-químicas de dezesseis marcas de farinhas de trigo tipo enriquecidas, comercializadas no Distrito Federal. Author(s): ROSA-CAMPOS, A. A.; ROCHA, J. E. da S.; BORGO, L. A. Resumo: A farinha de trigo, muito utilizada na indústria alimentícia, é o produto elaborado com grãos de trigo. Sua qualidade pode ser avaliada pela composição centesimal, o que é de grande valia, poi... ... Repository: BDPA Publication year: 2014
Distribuição espacial das propriedades eletromagnéticas e gamarradiométricas do solo e sua relação com o relevo e atributos químicos e físicos do solo. Author(s): RODRIGUES, H. M.; VASQUES, G. M. O mapeamento detalhado dos atributos do solo requer um grande número de amostras de campo, o que poderia ser facilitado pelo uso de sensores eletromagnéticos de campo, ditos sensores proximais. A port... ... Repository: BDPA Publication year: 2016
Analysis of expressed sequence tags from Musa acuminata ssp. burmannicoides, var. Calcutta 4 (AA) leaves submitted to temperature stresses. In order to discover genes expressed in leaves of Musa acuminata ssp. burmannicoides var. Calcutta 4 (AA), from plants submitted to temperature stress, we produced and characterized two full-length en... ... Repository: BDPA Publication year: 2005
Comparative untargeted metabolome analysis of ruminal fuid and feces of Nelore steers (Bos indicus). Author(s): COLNAGO, L. A.; PALHARES, J. C. P.; BERNDT, A.; REGITANO, L. C. de A. We conducted a study to identify the fecal metabolite profle and its proximity to the ruminal metabolism of Nelore steers based on an untargeted metabolomic approach. Twenty-six Nelore were feedlot wi... ... Repository: BDPA Publication year: 2021
