The book is a comprehensive compilation of the most recent advances in the practical approach of the use of microbial probiotics for agriculture. Unlike the rest of the publications about biofertilizers, this book bridges the gap between the lab studies (molecular, physiological, omics, etc.) and the agronomic application. .
