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.
Soil tillage emits greenhouse gases, so reducing tillage could both reduce greenhouse
emissions and improve soil quality. In Europe about 25 % of arable land
is managed under reduced tillage, but a major drawback for organic farmers is
the increase in weed
infestation. This study compared reduced tillage and conventional tillage
in a 2002–2011 field experiment in Switzerland.
Weed abundance was 2.3 times higher under reduced tillage, however yields were similar for reduced tillage and
conventional tillage. This study represents the first
long-term trial under organic management showing that reduced tillage
improves environmental performance.
