Assessing soil organic matter changes in an organically managed long-term crop rotation experiment
MetadataShow full item record
Changes in soil organic matter (SOM) contents over time and measurements of SOM quality during a ‘snapshot in time’ for two different crop rotations at a long-term organically managed experiment in north east Scotland were investigated. Rotation 1 consisted of 3 years of grass/clover followed by 3 years of arable crops. Rotation 2 consisted of 4 years of grass/clover followed by 2 years of arable crops. There were no identifiable long-term changes in SOM contents for either of the rotations and no significant differences in SOM contents between rotations after 15 years. SOM quality, however, as indicated by properties such as aggregate stability measured for each rotation after 11 years, was greater for Rotation 2. Overall, SOM conditions were favourable in both rotations but were generally better in the rotation with the higher proportion of grass/clover.
