Technical notes
Authoritative guidance informed by research

SRUC and SAC Consulting are well known for their technical notes. These provide detailed advice to land managers on a wide range of issues and are informed by research and practice in the field.
The production of some of these technical notes has been possible with funding from the Farm Advisory Service (FAS) - part of the Scottish Rural Development Programme (SRDP) which is co-funded by the EU and Scottish Government, providing information and resources aimed at increasing the profitability and sustainability of farms and crofts.
