Biological Nitrogen Fixation Associated with Rice Production: Based on selected papers presented in the International Symposium on Biological Nitrogen [Hardcover]

Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers.
Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production.
This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.Introduction: Some comments about a better use of biological nitrogen fixation in rice cultivation.- 1.
