We should be able to learn a lot about azotobacter from Cuba where mass
production of this and other biofertilizers has progressed to where the
use of azotobacter, for example, has provided 40-50% of the nitrogen
needs of non-leguminous plant production, according to the Cuban Ministry
of Agriculture. The best way I know of to access the research driving
this biofertilizer program that I understand is unique to Cuba, is via
Peter Rosset, the agroecologist director of Food First and co-author of
THE GREENING OF THE REVOLUTION: Cuba's Experiment with Organic
Agriculture. Email: foodfirst@igc.apc.org
