图书描述

This book demonstrates that American agricultural development was far more dynamic than generally portrayed. In the two centuries before World War II, a stream of biological innovations revolutionized the crop and livestock sectors, increasing both land and labor productivity. Biological innovations were essential for the movement of agriculture onto new lands with more extreme climates, for maintaining production in the face of evolving threats from pests, and for the creation of the modern livestock sector. These innovations established the foundation for the subsequent Green and Genetic Revolutions. The book challenges the misconceptions that, before the advent of hybrid corn, American farmers single-mindedly invested in labor-saving mechanical technologies and that biological technologies were static.

回答的问题是美国是如何一步步走到农业大国的地位的。本书选了小麦、玉米、棉花、烟草、加州的作物、牲畜等代表性农产品进行了阐述。作者着力在于反驳原有的机械化提高生产力的假说，强调生物技术进步——由政府、学校和农户参与的选种育种等工作对农业生产力的进步起到了极大作用。分作物写的，非常细致，如果最开始能有institutional background就更好了。
