| Core
& Satellite sites |
|
| Ten sites have
been identified in Britain, ranging from Elgin in Morayshire
to Whitfield in Kent. All sites are representative of different
soil types and
conditions. Five of these are ‘core sites’ and include relevant
HGCA-funded
trials already in situ. The remaining five ‘satellite’ sites
are largely based on
‘volunteered’ farms – some of which are trying non-inversion
tillage for the
first time. |
