Soil Inversion Project: more information
We began this project in 2000, to research if trees planted in soil deep ploughed to a depth of a metre, would have a better chance of establishing successfully than trees planted conventionally.
We also want to know if they will withstand extreme weather incidents and temperature stress brought on by climate change.
More infertile
soil conditions created by bringing up the subsoil to the surface also allow
sowings of wildflower seeds for biodiversity benefits.
Findings described in the new publication show that tree growth and survival
can be significantly improved on deep ploughed areas in light soils, compared
to conventional methods. Tree root penetration is faster and root balls more
extensive, enabling trees to access moisture held at depth and improve their
stability.
Impacts for farmland birds and general biodiversity gains have also started
to show positive results, possibly in part due to much reduced usage of herbicides
needed on these sites where the wildflowers act as a food source and soil
stabiliser.
Trials have been carried out with a focus on the North West and East Midlands,
with over 150 hectares deep ploughed on 20 sites between 2002 and 2006. Monitoring
has been undertaken on 4 sites and we have established a relationship with
Manchester Metropolitan University to secure a current PhD student research
programme.
We are also keen to explore the benefit of these new woodland wildflower areas
on people. During the development of trial sites in 2005/6, we worked with
local people and community groups in the East Midlands and North West. We
are keen to extend this with partners as the project continues to monitor
* levels and
diversity of involvement
* health and well-being outcomes
* awareness and understanding of local climate change
* sustainability of new woodlands and wildflower sites
