Ecological Aspects of Nitrogen Acquisition covers how plants compete for nitrogen in complex ecological communities and the associations plants recruit with other organisms, ranging from soil microbes to arthropods. The book is divided into four sections, each addressing an important set of relationships of plants with the environment and how this impacts the plant's ability to compete successfully for nitrogen, often the most growth-limiting nutrient. Ecological Aspects of Nitrogen Acquisition provides thorough coverage of this important topic, and is a vitally important resource for plant scientists, agronomists, and ecologists.
