- Liming to raise pH could take years, see SRUC technical note for guidance on rates
- Robin Walker from SRUC has provided some short videos of their long term experiments at Craibstone, one of which is a technical video about the pH rotation started in 1961 and also a time lapse video which may be of interest.
- Discussion of direct drilling: Look at the work of farmer Gabe Brown from North Dakota. There are many more videos on You Tube about his use of direct drilling, mixed species cover crops and holistic planned grazing. His book 'Dirt to Soil' is an interesting read.
