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
Bioavailability of soil Cu, Fe, Mn and Zn from soil fractions. Author(s): FONTES, R. L. F.; FERREIRA, G. B.; VENEGAS, V. H. A.; NEVES, J. C. L.; FARIA, A. F. de; FONTES, M. P. F. Cationic micronutrients bioavailability depends on the chemical characteristics of soil fractions. Fourteen soils received individual doses of five micronutrients (Cu, Fe, Mn, Zn, B) arranged in seven... ... Repository: BDPA Publication year: 2021
Sequential extraction of Cr, Cu and V in soil and determination using ICP·MS. Author(s): NOGUEIRA, A. R. de A.; BIANCHI, S. R.; NÓBREGA, J. A. Among the instrumental techniques that can be useel for eletermination of trace elements in soils inductively coupled plaSl1la mass spectroscopy (ICP-MS) presents aelvantages such as multielemental ch... ...

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
A non-archimedean dea model to assess group comparisons. Author(s): SOUZA, G. da S. e; GOMES, E. G. We consider the use of the non-Archimedean infinitesimal epsilon in DEA-CCR models. The application of interest is defined by the performance measure of the Brazilian Agricultural Research Corporation... ... Repository: BDPA Publication year: 2016
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
Chemical and physical fractions of soil organic matter under various management regimes in Roraima, Brazil. Author(s): GUARDIOLA, M. D. E.; VALE JÚNIOR, J. F. do; SILVA, E. E. da; ROSSI, C. Q.; PEREIRA, M. G. Repository: BDPA Publication year: 2017
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
Formas de P em Latossolo Vermelho-Amarelo sob pastagem após dois e sete anos da adubação fosfatada. Author(s): SELHORST, B. S.; SCHLINDWEIN, J. A.; MARCOLAN, A. L.; PANSONATO, B. da S.; VALOIS, C. A. da S. Em solos mais intemperizados como os Latossolos, o uso de adubações fosfatadas, pode garantir a maior disponibilidade de fósforo para as plantas. Esse estudo teve por objetivo avaliar as formas de fós... ... Repository: BDPA Publication year: 2022
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
