This book is the most up-to-date and comprehensive review of our knowledge of the management of mycorrhizas in agriculture, horticulture and forestry. It contains twenty-four reviews written by leading international scientists from eight countries. The reviews consider the ecology, biology and taxonomy of arbuscular and ectomycorrhizal fungi, the information and functioning of mycorrhizas and opportunities for managing these symbioses. The book will be essential reading for scientists and advisors responsible for ensuring that the maximum benefit is obtained from mycorrhizal symbioses in agriculture, horticulture and forestry and in the reclamation of degraded lands.
