Crop rotation affected soil structure and crop yield. The R2
(a winter crop rotation) resulted in the poorest soil structural quality
and produced the least relative yield compared to R3 and R4.
Tillage systems clearly influenced soil quality and relative yield.
The MP resulted in the best soil structural quality, and the highest
relative yield compared with reduced tillage.
Significant correlations were found in most cases between soil
quality indices and relative yield. This demonstrates that soil
quality indices, especially those based on soil structure, can reflect
a soils crop yield potential, and thus the provisioning function of
that soil.
