Understanding the changes in soil labile C and enzyme activities under different land uses is important to maintain soil quality and health and for sustainable land use.
Assuming, first, that 1 to 2 Mg/ha of straw is left on the land in order to maintain soil quality and, secondly, that a 90% yield of ethanol from carbohydrate is achieved, the total potential for EU bioethanol production from wheat straw lies between 39 and 48 gigalitre (GL) per year [ 1- 4].
Furthermore, insecure land tenure reduces people's incentives to maintain soil quality because they have no permanent rights to the land.
Although the importance of bacteria for ecosystem functions and maintaining soil quality in agriculturally managed systems has long been recognized, the influence of land use type and management type on soil bacterial communities is poorly understood.
Labor scarcity and land abandonment caused by rural labor out-migration have complex effects on land quality and soil erosion, especially in hill-mountain areas that have been substantially transformed by human settlement and maintained with labor-intensive production practices.
The output includes visual land quality diagrams and interactive land quality and land attribute quality maps.
For higher land qualities, these costs depend on the land quality and on the biodiversity impacts.
Wheat yield was used as a proxy for land quality.
Further studies were done to model water quality, siltation, climate effects and change in land quality.
Soil quality enrichment improves the capacity of a soil function within ecosystem and land use boundaries to sustain productivity, maintain environmental quality, and promote plant and animal health (Doran and Parkin 1994; Karlen et al. 1997).
