The isotopic composition (d15N, d13C) of agricultural wastes and derived composts. Author(s): INACIO, C. de T.; MAGALHÃES, A. M. T.; SOUSA, P. O.; CHALK, M. The aim of this study was to measure variations in the isotopic composition (d13C and d15N) during the composting of different agricultural wastes using bench-scale bioreactors. Four different feedsto... ... Repository: BDPA Publication year: 2013

Biological nitrogen fixation in field-grown sorghum under different edaphoclimatic conditions is confirmed by N isotopic signatures. Author(s): BARROS, B. G. de F.; FREITAS, A. D. S. de; TABOSA, J. N.; LYRA, M. do C. C. P. de; MERGULHÃO, A. C. do E. S.; SILVA, A. F. da; OLIVEIRA, W. da S.; FERNANDES JUNIOR, P. I.; SAMPAIO, E. V. de S. B. The association between sorghum and N2-fixing bacteria has been assessed only under limited conditions. We investigated biological nitrogen fixation (BNF) in situ in fifteen sorghum genotypes with dry... ... Repository: BDPA Publication year: 2020
