This is perhaps one of the oldest known films on the Keyline concept filmed on PA Yeomans' former farm 'Nevallan' circa 1955. Its somewhat remarkable from a few perspectives:
* It was produced by a Bank
* It was made at a time when fertiliser technology in agriculture was promising subsidised fertility out of a bag as opposed to conscious design and management of the natural elements
* It is 55 years on and we still have landscapes that rapidly shed water, soils that are eroding, rural communities shrinking, cities not feeding and watering themselves etc. etc. etc.
Thanks very much to Geoff Booth for archiving and digitising this film and for providing it to me to share.
