简介
An agricultural scientist and researcher examines the rice-wheat cropping system practiced over time on the Indo-Gangetic Plain, focusing on the evidence showing changes in productivity. He proposes reasons for such changes, discusses the impact of the system on soil fertility and water supplies, and discusses increasing demands for better fertilizers and pesticides. Of likely interest to agronomists, policymakers, and agroeconomists. Simultaneously co-published as , Volume 3, Number 2 (#6) 2001. Annotation c. Book News, Inc., Portland, OR (booknews.com)
