Cyanobacteria: A potential biofertilizer for rice

Resonance 06/2004; 9(6):6-10. DOI: 10.1007/BF02839213


Application of high input technologies has resulted in significant increase in agricultural productivity. There is, however,
a growing concern about the adverse effects of indiscriminate use of chemical fertilizers on soil productivity and environmental
quality. Cyanobacteria offer an economically attractive and ecologically sound alternative to chemical fertilizers for realizing
the ultimate goal of increased productivity, especially in rice cultivation. In a wetland rice ecosystem, nitrogen fixation
by free living cyanobacteria also significantly supplements soil nitrogen.
