Book Description
Nowadays the environmental sustainability of the cropping systems is increasingly requested by the consumers. Conventional tillage practices, totally turning over the soil between the vineyard rows, may cause erosion due to rain as well as structure destruction of the soil in the long term. Conservation tillage is a soil management technique, poorly widespread in Sardinia, allowing cover cropping between vineyard rows. Furthermore, this technique makes the canopy development control of herbage possible by cutting it up during specific phenological phases. Conservation tillage usually involves direct benefits to farmers such as increasing soil fertility as well as reductionof tillage costs, soil erosion and carbon dioxide (CO2) emissions in the atmosphere. This long term trial, during at least five years aims to assess the conservation tillage impact on chemical-physical soil characteristics in comparison with traditional tillage by evaluating the change of organic matter, C.E.C. and availability of major plant nutrients in the soil and to estimate their probable rise. The field plots are located in a 35% slope condition vineyard, showing massive erosion problem and organic matter low content. A split/plot design with four replications was set up, with the comparison between conservation and traditional tillage apart as main plots. Moreover, the effects of two different irrigation levels were evaluated in the subplots of each main plot. At the beginning of the trial (2011) a pedological survey was made. Three soil profiles were described and sampled along the field slope and soil sampling in each plot were made both to characterize the soil and to find the zero point. The soil chemical and physical characteristics were monitored through a second soil sampling made at the end of 2013. Conservation tillage caused increasing organic matter content and C.E.C. values. As for major plant nutrients in soil, results were more uncertain. Grapevine yield and quality parameters did not show any negative effect when passing from conventional to conservation tillage techniques. The trial provided a preliminary positive evaluation of conservation tillage. However, more years are required to confirm this trend.

Book Description
Discover farming techniques that will decrease soil erosion and costs! Soil erosion from U.S. croplands has long been recognized as a national problem. Conservation Tillage in U.S. Agriculture: Environmental, Economic, and Policy Issues is the first ever complete study of the costs and benefits of using conservation tillage to prevent soil erosion. Designed for professionals working in the areas of soil science, agronomy, economics, environmental studies, and agriculture, this complete study covers everything from machinery and trends in conservation tillage to its adoption to use in regions of the United States. With this in-depth manual, you will examine different types of tillage and the many benefits this practice can ensure, such as improving water quality, increasing organic matter in your soil, sequestering carbon, and providing habitat and food for wildlife. Covering the economic, environmental, and policy issues of this practice, Conservation Tillage in U.S. Agriculture features: the history of conservation tillage case studies on costs and benefits of differing conservation tillage practices with various crops tables and graphs of trends, and case studies concerning the use of different farming methods U.S. Department of Agriculture soil conservation policies how to prevent soil erosion without harming the environment factors affecting conservation tillage, adoption, and use for crops such as peanuts, potatoes, beets, tobacco, and vegetables. With the help of this book, you will measure the benefits and costs of conservation tillage based on profitability and environmental impact and explore the positive and negative environmental consequences that may involve air, land, water, and/or the health and ecological status of wildlife. Conservation Tillage in U.S. Agriculture is a timely and informative look at conservation tillage practices that will help you improve residue management and create better conditions for wildlife and the environment.

Book Description
"The purposes of this guide are to provide information to Soil Conservation Service (SCS) Field Office Personnel on the control of nonpoint sources of pollution from agricultural lands and to incorporate a water quality perspective into all conservation planning. Nonpoint source pollution is both a relatively concern and a complex phenomenon with many unknowns. Knowing the extent to which agricultural sources contribute to the total pollution load, the extent to which various control practices decrease this load, and the effect of reducing the pollutants delivered to a water body are basic to the achievement of water quality."--Page 3

Book Description
This book describes concepts, value judgments and background information on the expanding conservation tillage practices in the United States and provides a technical appraisal of the state of the art. Still, much remains to be learned about the agronomic, agricultural engineering and environmental parameters; and it is hoped that the inormation herein presented will stimulate further research toward a more integrated apporach to conversation tillage practices.
