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
Better experimental design and statistical analysis make for more robust science. A thorough understanding of modern statistical methods can mean the difference between discovering and missing crucial results and conclusions in your research, and can shape the course of your entire research career. With Applied Statistics, Barry Glaz and Kathleen M. Yeater have worked with a team of expert authors to create a comprehensive text for graduate students and practicing scientists in the agricultural, biological, and environmental sciences. The contributors cover fundamental concepts and methodologies of experimental design and analysis, and also delve into advanced statistical topics, all explored by analyzing real agronomic data with practical and creative approaches using available software tools. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.

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.

Book Description
Large-scale crop residue removal for livestock or biofuel production may negatively affect soil and water resources. A combination of management practices could be the key to manage such resources under increasingly variable climate. For instance, use of cover crops (CCs) could offset the negative impacts that corn (Zea mays L.) residue removal may have on soil water and energy balance. We studied: 1) the effect of corn residue removal (56%) with and without winter rye (Secale cereale L.) CC on soil hydraulic and thermal properties including water infiltration, water retention, pores-size distribution, thermal conductivity, specific heat capacity, and thermal diffusivity, 2) whether CCs offset any negative impacts of residue removal effects on the above properties, and 3) relationships of hydraulic and thermal properties with soil organic C and other properties. An experiment of corn residue removal and CCs in an irrigated no-till continuous corn located in south central Nebraska was used. All soil properties were measured 5 and 6 years after experiment onset except water infiltration and soil thermal properties, which were measured only after 6 years. Cover crops generally had no effect on soil hydraulic and thermal properties but increased soil organic C concentration (p = 0.10) in the 0 to 5 cm depth. However, corn residue removal consistently affected soil properties in the 0 to 10 cm soil depth. Residue removal reduced cumulative infiltration by 22 to 58% compared with no removal. It also reduced available water by 21 to 31%, thermal conductivity by 19 to 28%, specific heat capacity by 23 to 28%, soil wet aggregate stability by 17 to 30%, and soil organic C concentration by 25% in the 0 to 5 cm depth. The reduction in available water with residue removal was strongly correlated with a decrease in soil organic C concentration and wet aggregate stability. Thermal conductivity decreased with a decrease in soil water content, soil organic C, and bulk density due to residue removal. In conclusion, corn residue removal negatively impacted soil hydraulic and thermal properties and CCs were unable to completely offset but partially mitigated the negative impacts of residue removal.

Book Description
Recent changes in the Conservation Compliance Plans for farmers shows the need for improved information on the effective management of crop residues. Residue management requires an understanding of the crop, soil, and climate in which the farming system is located. In this volume, the strategies for effective residue management are described for each region of the country to provide a comparison of the regional differences. The chapters not only describe the knowledge in each region but also suggest some of the needed areas of research required to develop an improved understanding of the processes involved in effective residue management.
