Nitrogen fixation with blue green algae and fertility of paddy soil


, : Nitrogen fixation with blue green algae and fertility of paddy soil. Journal of Soils and Crops 5(2): 169-171

Results from a field experiment carried out in Nagpur, India, showed that application of 20 kg blue green algae (Cyanobacteria) and 50 kg N/ha increased N uptake by rice and soil N fixation.
