Conteúdo: |
New Zealand agriculture is heavily dependent upon fixed nitrogen de rived from the rhizobiurn-legume symbiosis, and rhizobia are widespread in soils. It has recently been established that some strains of rhizobia denitrify at high rates in liquid culture and in sterile soils under labora tory conditions. The significance of this rhizobial denitrification in agri cultural ecosystems is uncertain. It may aid rhizobial survival in anaerobic conditions, and alleviate nitrate inhibition of symbiotic nitrogen fixation: but it will result in the removal of fixed nitrogen, thus contributing to the chronic nitrogen deficiency prevalent in New Zealand pastoral systems |
