Book Description
The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about soil and crop management, and to test models and future concepts concerning SOM management. A database is included with the book, presenting tabular data for 34 sites in North America. Soil Organic Matter in Temperate Agroecosystems discusses all of these issues and more, answering such questions as:

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.

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
Zone and deep zone tillage are both types of conservation tillage that have been studied in agronomic cropping systems. There has been little research on the use of these types of conservation tillage in vegetable production systems. The objectives of this research were to examine the effects of conservation tillage systems on crop yield and quality, weed management, and soil properties in a vegetable production system. If crop yield and quality is similar between conventional tillage (CT) and zone (ZT) or deep zone tillage (DZT), then there is an increased incentive for growers to adopt a system of tillage that saves time, fuel, and has the potential to improve soil quality. Tillage and weed control plots were established in 2004 to evaluate the long term effects of conservation tillage on crop yield and quality, weed management, and soil properties in sweet corn and dry beans. The experiment made use of a randomized complete block split-split plot design and contained four replicates. The main plot was three tillage treatments CT, DZT and ZT which were assigned randomly. The first split was by weed control. Three methods of weed control were used conventional full width (CFH), banded plus cultivation (BH), and cultivation only (CUL). The second split was by cultivar, early and late cultivars of both crops were assigned to each tillage treatment. Tillage affected soil penetration resistance in both crops in 2006 and in 2007. Between and in row penetration resistance in sweet corn in the ZT treatment was higher than in the CT treatment at all depths in 2007. Compared to the CT treatment penetration resistance between-row for dry beans was higher in the ZT treatment at the 12.5 to 20 cm depth in both years. While tillage affected soil nitrogen mineralization in sweet corn and dry beans in 2006, the magnitude of the measured differences was small and would not likely have practical impact on crop yields. Dry weed biomass in-row was not significant across tillage treatments in sweet corn in both years. Tillage had a significant effect on in row dry weed biomass in dry beans in 2006 but not in 2007. In- row dry weed biomass in dry beans was not affected by tillage in 2007. The use of full width herbicides (CFH) resulted in lower weed biomass in-row than the CUL treatments, in both years. While other sweet corn yield and quality parameters were affected by tillage, marketable yield (kg[MIDDLE DOT]ha-1) of sweet corn was similar in the CT, DZT, ZT treatments in 2006 and in 2007. With the exception of plant number per hectare in 2006, tillage did not have an affect on dry bean yield and quality in 2006 or in 2007. These results indicate that deep zone and zone tillage may be a viable alternative to conventional tillage in the Northeastern United States.
