Production of food fibre and fuel is vital for humanity, and as the world population continues to rise, demands on these resources is ever increasing. In a context of growing worldwide concern about sustainability and environmental impacts of cropland, grassland and forestry practices, this textbook provides an introduction to the processes that define the ecology and environment of plant production. Core principles are examined such as soil-plant relationships, genetic manipulation and diversity, yield and water requirements, as well as physical factors such as solar radiation, temperature and weather. Fully updated with new chapters on climate change and biofuels, this edition is an important text for students and researchers in agronomy, forestry, botany, ecology and environmental sciences. Praise for the first edition: \'I highly recommend this book for undergraduate students in plant production courses. It is easy to read, well-structured and of high scientific level...also useful for a more general readership\' Scientia Horticulturae
