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
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
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
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
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
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... ...
