Phosphorus Fractions and Their Transformations in Entisol. Author(s): ALOVISI, A. M. T.; ALOVISI, A. A.; SERRA, A. P.; TOKURA, L. K.; DAVIDE, L. M. C.; LOURENTE, E. R. P.; SILVA, R. S. da; TOKURA, W. I.; SOUZA, D. A. de; MAR, G. D. do The availability of phosphorus in the soil is a factor that directly interferes with its absorption by plants. This availability can be influenced by the texture, dose of the phosphate fertilizer and... ... Repository: BDPA Publication year: 2019
Lignocellulosic biomass: organosolv process for lignocellulosic biomass fractionation. Author(s): GAMBETTA, R. Organosolv process for lignocellulosic biomass fractionation that eliminates the washing step and decreases the precipitation of dissolved/extracted lignin on cellulose fibers. Repository: BDPA Publication year: 2021
Dynamic of Phosphorus Fractions in Typic Quartzipsamment Soil Cropped With Bean. Author(s): ALOVISI, A. M. T.; SERRA, A. P.; ALOVISI, A. A.; TOKURA, L. K.; LOURENTE, E. R. P.; CARNEIRO, L. F.; SILVA, M. A. C. da; DAVIDE, L. M. C.; SANTOS, S. C.; SILVA, R. S. da Phosphorus is the most limited nutrient in Brazilian soils for plant growth, resulted of low availability and poor P content in bedrock. The aim of the study was to evaluate the dynamic of P fractions... ... Repository: BDPA Publication year: 2018
Phosphorus fractions in soil with organic and mineral fertilization in integrated crop-livestock system. Author(s): RIGO, A. Z.; CORREA, J. C.; MAFRA, A. L.; HENTZ, P.; GROHSKOPF, M. A.; GATIBONI, L. C.; BEDENDO, G. C. Abstract: Use of organic fertilizers in integrated crop-livestock (iCL) systems may affect soil phosphorus fractions. This study aimed to determine phosphorus fractions in the soil under the iCL syste... ... Repository: BDPA Publication year: 2019
Zinc fractionation in cow, goat, sheep and soybean milk samples using gel-electrophoresis and determination by electrothermal atomic absorption spectrometry (ETAAS). Author(s): BOSSU, C. M.; GIGLIOTI, R.; OLIVEIRA, M. C. de S.; OLIVEIRA, P. V. DE; NOGUEIRA, A. R. de A. A screening method for zinc levels in different milk samples (raw cow, raw sheep, UHT cow, UHT goat and soybean milk base) was performed to establish the Zn levels' differences in protein samples. The... ... Repository: BDPA Publication year: 2021
Extraction and characterization of organic fractions isolated from a China Ball Clay quarried in Devon Sout West England. Author(s): MCINERNEV, R.; STUART, J.; NOVOTNY, E. H.; HAYES, M. H. B.; YOUNG, K. China Ball clay has been used for centuries in the tiling and pottery-ware industry. Because it is much finer than the other components in the casting slip the ball clay dominates the particle-particl... ... Repository: BDPA Publication year: 2008
Copper and zinc accumulation, fractionation and migration in vineyard soils from Santa Catarina State, Brazil. Author(s): BRUNETTO, G.; COMIM, J. J.; MIOTTO, A.; MORAES, M. P.; SETE, P. B.; SCHMITT, D. E.; GATIBONI, L. C.; MELO, G. W. B. de; MORAIS, G. P. The purpose of this study was to evaluate Cu and Zn migration and fractions in sandy soil of vineyards. In Urussanga (SC), Brazil, soil samples were collected from a 4-year-old and 15-yearold vineyard... ... Repository: BDPA Publication year: 2018
Soil organic matter fractions as a short-term indicator of carbon turnover under agricultural systems. Author(s): MATOS, E. da S.; CONCEIÇÃO, M. C. G. da; BIDONE, E. G.; RODRIGUES, R. de A. R.; CORDEIRO, R. C. Integrated crop-livestock-forest (ICLF) systems has been considered as an important strategy to enhance C sequestration. However, changes in soil C due to agricultural management practices, in general... ... Repository: BDPA Publication year: 2017
Organic matter fractions in a Quartzipsamment under cultivation of irrigated mango in the lower São Francisco Valley region, Brazil. Author(s): CARDOSO. J. A. F.; LIMA, A. M. N.; CUNHA, T. J. F.; RODRIGUES, M. A.; HERNANI, L. C.; AMARAL, A. J. do; OLIVEIRA NETO, M. B. de In this context, the aim of the present study was to evaluate the impact of growing irrigated mango on the organic carbon (OC) stocks, the C in humic substances, and the C of the heavy fraction and li... ... Repository: BDPA Publication year: 2015
Mapping Fractional Cropland Distribution in Mato Grosso, Brazil Using Time Series MODIS Enhanced Vegetation Index and Landsat Thematic Mapper Data. Author(s): ZHU, C.; LU, D.; VICTORIA, D. de C.; DUTRA, L. V. Mapping cropland distribution over large areas has attracted great attention in recent years, however, traditional pixel-based classification approaches produce high uncertainty in cropland area stati... ...
