We are no longer updating the Research Digest. All content remains.
The Permaculture Research Digest has summaries of newly published permaculture-related research. All items are hyper-linked to the original publication.
The 'January 2013' archive contains 60 items published in 2012.
Items marked with a # have restricted public access, although abstracts are freely available.
Degraded soil structure recovery is much less documented than structure
degradation and compaction. In this field experiment, the
effects of rotary spade tillage followed by Sorghum cover crop on the degraded structure of the soil from an
orchard were evaluated. A large and significant
improvement of the structure quality scores were obtained. Analysis revealed a significant
impact of the tillage and root development on the structure recovery,
larger than the effect of SOC content. This structural change pattern was similar to those reported from other
studies. Though the observed final structure
quality of the top layer was good, its vulnerability
remains large due to its small SOC to clay ratio.
