Hierarchical pedotransfer functions for predicting bulk density in Brazilian soils. Author(s): REIS, A. M. H. dos; TEIXEIRA, W. G.; FONTANA, A.; BARROS, A. H. C.; VICTORIA, D. de C.; VASQUES, G. M.; SAMUEL-ROSA, A.; OTTONI, M. V.; MONTEIRO, J. E. B. de A. Bulk density (BD) is a soil physical property used as a soil quality indicator and variations in this measurement influence soil water content and carbon stock estimates. This study aims to compile a... ... Repository: BDPA Publication year: 2024
Accuracy of pedotransfer functions to estimate soil bulk density in Brazil. Author(s): HUF DOS REIS, A. M.; TEIXEIRA, W. G.; FONTANA, A.; BARROS, A. H. C.; VICTORIA, D. de C. Soil bulk density is an important soil physical property, used as a quality indicator. Its variation influences soil water content and carbon stock estimates. This study aims to evaluate the accuracy... ... Repository: BDPA Publication year: 2022
Soil bulk density and biomass partitioning of Brachiaria decumbens in a silvopastoral system. Author(s): PACIULLO, D. S. C.; CASTRO, C. R. T. de; GOMIDE, C. A. de M.; FERNANDES, P. B.; ROCHA, W. S. D. da; MULLER, M. D.; ROSSIELO, R. O. P. Shade in silvopastoral systems improves the thermal comfort of animals, but it may also affect the pasture productivity and can contribute to soil compaction in the shaded areas due to the increase in... ...

Soil aggregation, organic carbon concentration, and soil bulk density as affected by cover crop species in a no-tillage system. Author(s): NASCENTE, A. S.; LI, Y.; CRUSCIOL, C. A. C. Soil aggregation and the distribution of total organic carbon (TOC) may be affected by soil tillage and cover crops. The objective of this study was to determine the effects of crop rotation with cove... ... Repository: BDPA Publication year: 2015
Cover crops species as affecting soil aggregation, aggregate stability, organic carbon concentration and soil bulk density in different soil aggregate fractions. Author(s): NASCENTE, A. S.; LI, Y.; CRUSCIOL, C. A. The objectives of this study were to elucidate the effects of crop rotation with cover crop species in the soil aggregation, total organic carbon concentration in the whole soil and in the soil aggreg... ...
