AN IMPROVIZED TECHNIQUE FOR MEASUREMENT OF NITROGEN FIXATION BY BLUE GREEN ALGAE AND AZOLLA USING MOIST SOIL CORES FROM RICE FIELDS

A modified technique for measurement of nitrogen fixation by blue green algae and Azolla sp. using intact, moist soil cores was developed for use in field studies in which chemical fertilizers, blue green algae and Azolla biofertilizers had been used in association with a rice crop. This method invo...
