Book Description
Winter cover crops provide a range of benefits in corn production systems. Among these are increased nutrient scavenging and decreased soil erosion. Establishment of cover crops following early season corn requires planting as early as September, but germination of many cool-season cover crop species is severely restrained by high soil temperatures (secondary dormancy). This study compares germination and establishment of populations from four legume species [balansa clover (Trifolium michelianum Savi.), berseem clover (T. alexandrinum L.), crimson clover (T. incarnatum L.), and hairy vetch (Vicia villosa Roth)] selected for heat tolerance. Laboratory germination results showed a significant reduction in secondary dormancy in hairy vetch. Field trials suggest that optimal planting date of the most advanced population of each species is September. Crimson clover and hairy vetch provided the greatest weed control, while grain yields following legume cover crop treatments were similar to yields from 56 and 112 kg N ha−1.

Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Book Description
Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.
