Functional Diversity of Mycorrhiza and Sustainable Agriculture is the first book to present the core concepts of working with Arbuscular mycorrhizal fungi to improve agricultural crop productivity. Highlighting the use of indigenous AM fungi for agriculture, the book includes details on how to maintain and promote AM fungal diversity to improve sustainability and cost-effectiveness. As the need to improve production while restricting scarce inputs and preventing environmental impacts increases, the use of AMF offers an important option for exploiting the soil microbial population. It can enhance nutrient cycling and minimize the impacts of biotic and abiotic stresses, such as soil-borne disease, drought, and metal toxicity. The book offers land managers, policymakers, soil scientists, and agronomists a novel approach to utilizing soil microbiology in improving agricultural practices.

A meta deste livro interpretar e comparar as concep es de Tom s de Aquino (1224/1225 - 1274) e Dietrich de Freiberg (ca. 1240 - ca. 1318) sobre a natureza de conceitos emp ricos. Numa caracteriza o preliminar, tais conceitos s o aquelas representa es mentais que nos permitem classificar indiv duos em tipos naturais de acordo com caracter sticas emp ricas. O que faz de um conceito desse tipo uma representa o? O que o distingue, enquanto representa o sobre coisas que podem existir realmente, de representa es fict cias? Trata-se de Investigar as respostas de Tom s e Dietrich para ambas as quest es.
