Consolidates over 40 years of experience in New Zealand's use of seed inoculation
Describes the process of rhizobia in detail
Discusses New Zealand"s method of producing good quality grasslands and how it may be easily duplicated in other countries around the world


Seed inoculation is the practice of effectively introducing a high number of nitrogen-fixing bacteria (Rhizobium or Bradyrhizobium) on the surface of legume seeds prior to planting. The bacteria penetrates the root, resulting in the formation of root nodules that fix nitrogen from the air, and make it readily available to the plant. This book describes the need, the development and the use of rhizobia, and how this process may be reproduced successfully around the world, especially in underdeveloped agricultural countries.
