Dr Douglas L. Karlen, USDA, Agricultural Research Service, National Laboratory for Agriculture and the Environment
Dr Karlen is an experienced research scientist in the Soil, Water, and Air Resources Research Unit at the USDA, Agricultural Research Service. His soil and crop management research program uses a systems approach involving research scientists and engineers, producers, action agencies, non-government organizations, agribusiness, and other state and federal partners to quantify physical, chemical, and biological effects of conventional and organic farming practices. His current focus is on sustaining or improving soil quality while striving to produce sustainable feedstock supplies for lignocellulosic biofuel production.

Cellulosic Energy Cropping Systems presents a comprehensive overview of how cellulosic energy crops can be sustainably produced and converted to affordable energy through liquid fuels, heat and electricity.
The book begins with an introduction to cellulosic feedstocks, discussing their potential as a large-scale sustainable energy source, and technologies for the production of liquid fuels, heat and electricity. Subsequent chapters examine miscanthus, switchgrass, sugarcane and energy cane, sorghums and crop residues, reviewing their phylogeny, cultural practices, and opportunities for genetic improvement. This is followed by a detailed focus on woody crops, including eucalyptus, pine, poplar and willow. Critical logistical issues associated with both herbaceous and woody feedstocks are reviewed, and alternate strategies for harvesting, transporting, and storing cellulosic materials are also examined. The final sectionof the booktackles the challenge of achieving long-term sustainability, addressing economic, environmental and social factors.
Cellulosic Energy Cropping Systems is a valuable resource for academics, students and industry professionals working in the field of biomass cultivation and conversion, bioenergy, crop science and agriculture.
Topics covered include:
* Identifying suitable cellulosic energy crops that are adapted to a wide range of climates and soils
* Best management practices for sustainably growing, harvesting, storing, transporting and pre-processing these crops
* The development of integrated cellulosic energy cropping systems for supplying commercial processing plants
* Challenges and opportunities for the long-term sustainability of cellulosic energy crops
This book was conceived and initiated by David I. Bransby, Professor of Energy and Forage Crops in the Department of Crop, Soil and Environmental Sciences at Auburn University, USA.
