Management Change On Soil Restoration
Of The Cereal-growing Regions Of Central Spain

Abstract
Practices that restore degraded agricultural soils are important for improving
overall environmental quality. In order to implement best practices that maintain
agricultural productivity and in the process restore soils and environmental
quality, there needs to be better understanding of how soil management affects
soil factors associated with and leading to soil degradation and desertification.
This study presents new information about how agricultural land management
changes affect soil restoration and SOC levels for cereal-growing regions of
central Spain. The results show extensification of agricultural practices using
long term pasture rotations (e.g. 5-year) may improve soil degradation via the
restoration of SOC levels.
Keywords: soil restoration, crop rotation, soil organic carbon, semi-arid,
Mediterranean, carbon sequestration.
1 Introduction
Cropland agriculture comprises a significant percentage of the world’s arid and
semi-arid regions. In these areas, the precipitation limitations, climate variability
and anthropogenic factors can lead to soils being vulnerable to degradation and
desertification. Soil degradation can be defined as the loss of productivity or
utility resulting from natural or anthropogenic factors (Lal [16]; Lal et al. [20])
and generally results from a set of interconnected processes, each often
categorized as being mainly a physical, chemical or biological soil process. The
factors that affect the level of degradation in semi-arid cereal-cultivated central
