Daftar Isi:
- The experiment was aimed to investigate the Al-tolerant mechanisms physiology of legume cover crops species related to metabolism NO3-, NH4+, and N02-. The results revealed that an addition of Al had less effect on Al-tolerant species compared to Al-sensitive in term of reduction in NO3-, NH4+ and N02- uptake. The reduction in Nitrit of the Al-tolerant species under Al treatment was less than in Al-sensitive species. The results suggested that in tolerant legume cover crops species, the higher level of Al tolerance seems to have emanated from efficient NO3- metabolism and the higher N02- to NH4+. Key words: Legume cover crop, aluminum tolerance, NO3-, NH4+ and N02-
