Diagnosis of the Nitrogen Status in Crops

Herausgegeben:Lemaire, Gilles

• Broschiertes Buch

Produktbeschreibung

Providing a link between theoretical and applied aspects of plant nutrition and agriculture, this book introduces new concepts in plant nutrition. It shows how these can be applied in order to assess the nitrogen status in crops and to improve nitrogen nutrition through optimized N fertilization management. In this way economic benefits can be obtained, while at the same time preventing detrimental effects on the environment. The main agricultural crops - grasses, wheat, barley, Durum wheat, maize, sorghum, grain legumes and potatoes - are covered. The book will be an invaluable source for agronomists.

It introduces new concepts in plant nutrition and shows how they can be applied in practice in order to assess the nitrogen status in crops and to improve nitrogen nutrition through optimized N fertilization management. Thus, economic benefits may be obtained from agriculture, while at the same time detrimental effects on the environment may be prevented. The the main agricultural crops such as grasses, wheat, barley, Durum wheat, maize, sorghum, grain legumes and potatoes are covered. The book is useful source for both agronomists and practitioners.
