The aim of this study was to evaluate the effectiveness of the different agricultural management
adaptive strategies considered in the framework of a regional climate change adaptation
roadmap in Navarre (Spain), from the point of view of soil physical indicators associated to soil
compaction and water retention. These indicators were chosen as representative of the potential of
these strategies to improve the soil physical condition. That for, the effectiveness of conservation
agriculture (CA), crop rotations (ROT), additions of organic matter (ExO), irrigation (IRR) and innovative
grassland management (GSS) was assessed by monitoring soil bulk density (BD) and soil
available water holding capacity (AWHC) in a network of 159 agricultural fields across homogeneous
agro-climatic zones in the region. A sampling protocol designed to compare groups of plots with or
without adaptive practices, and with equal soil characteristics within each zone, allowed to determine
the effect size of each strategy (measured as response ratios, RR, calculated as the relative value of BD
and AWHC in fields with adaptive management vs. without). Both parameters responded to soil and
crop management, although the observed effect was highly variable. Only the ExO strategy showed
an overall positive effect on BD. ROT, IRR and GSS displayed no effect and, in the case of CA, the
effect was negative. In terms of AWHC, although the results within the zones were heterogeneous,
the overall effect associated to the strategies ROT, ExO, IRR and GSS was neutral, and only CA
resulted in an overall negative effect. The observed variability in terms of the effectiveness of the five
strategies tested in this region highlights the need to understand the complexity of interrelationships
between management and dynamic soil properties at the regional scale. [--]
