Case Study: Peter & Henri Greig at Pipers Farm
Pipers Farm is a 50 acre permanent pasture family farm in Devon, with native-breed cattle and sheep herds. Peter and Henri Greig are the founders and farmers at Pipers Farm, and they also work to support an additional 25 family farms, to connect their customers with healthy produce that has been farmed with a focus on traditional, sustainable values.
Peter and Henri began mob-grazing three years ago to improve their soil health and increase the productivity of their grassland. When they first started mob grazing they noticed they were grazing the pasture too hard, so they’re now in the process of learning to optimise their grazing technique to leave more forage and allow a better root structure to develop.



Recording photos at specific sample sites on Soilmentor helps Peter and Henri to keep track of changes to their soil over time.

Soilmentor has given Peter and Henri a toolkit to stay in touch with their management journey, allowing them to monitor their soil health progress as they go:
“Soilmentor is an exciting revelation to us. It feels like we’ve opened a whole encyclopedia of wisdom, and we’re unravelling the ancient story of our land. Soilmentor has become our eyes and ears to monitor our regenerative farming journey, learning from nature as we go…
We got a good base line of soil health measurements last winter, and we’re excited to see how these might change after our efforts to increase resting periods in our grazing. The first holes we dug we realised our roots were very small, and we’re hoping to see our grass roots lengthen into the soil and improve our VESS scores”
The Greigs have been doing regular sward stick readings and recording their results in Soilmentor in order to optimise their mob grazing.
By tracking their forage with sward readings, they can monitor their DM/ha, and make sure they aren’t grazing their pasture too hard before moving their livestock on:
