Improving the nitrogen nutrition of maize by intercropping with cowpea
Denitrification in Rhizobium.
Thirty-three strains of Rhizobium were examined for their reduction of nitrate under anoxic conditions. Three patterns of dissimilatory nitrate reduction were observed: (1) reduction to N2O and N2… Expand
Nitrate Inhibition of Nodulation and Nitrogen Fixation by Supernodulating Nitrate‐Tolerant Symbiosis Mutants of Soybean
Several soybean mutants that form a greater number of nodules (supernodulation) and display a nitrate tolerant symbiosis (nts) phenotype when grown in sand with continuous additions of NO 3 − have… Expand
Nitrogen fixation, denitrification, and pleomorphic growth in a highly pigmented Spirillum lipoferum.
A strain of Spirillum lipoferum with intense red pigmentation was isolated from the roots of Cynodon dactylon "Coastal." This isolate vigorously reduced acetylene when grown in N-free, Na-malate,… Expand

NITROGEN FIXATION BY LEGUMES AND BLUE-GREEN ALGAL-LICHEN CRUSTS IN A COLORADO DESERT ENVIRONMENT'
Potential sources of fixed nitrogen in a Colorado desert environment were examined by the acetylene reduction method at the Deep Canyon Desert Research Center, near Palm Desert, California. In field… Expand
Fermentation of straw-based diets containing azolla (Azolla caroliniana Willd) using the Rumen simulation technique (Rusitec)
Abstract A series of experiments was conducted to evaluate the nutritive value of Azolla species ( Azolla caroliniana ) as a supplementaru source of dietary nitrogen for high fibre-based diets.… Expand
