The dramatic increases in population and living standards during the twentieth century have led to serious concerns over the sustainability and environmental impact of modern agriculture. This textbook will enable students from a broad range of backgrounds to gain a basic scientific understanding of the processes which define the ecology of plant production. The book begins with a consideration of global issues. This is followed by a series of chapters on the relationship between plant production and the environment; topics include ecological principles, the importance of genetic manipulation and diversity, historical development of agricultural ecosystems and yield increases, biophysical limits of productivity, the soil-plant relationship, and water requirements. The second section then considers the physical environment that influences plant production; it examines the effects of solar radiation, temperature, weather, and atmospheric gases. This book is essential reading for students of agronomy, plant science, ecology and environmental biology and for others with an interest in the sustainability of plant production and its associated environmental considerations.
