"Paul Wheaton talks about lawn care with Susanne Schneider. She shares about her hugelkultur beds. Susanne has a lot of hawkweed in her yard, which is allelopathic and prefers acidic, compacted soil. Paul would professionally test the soil pH. They talk about earthworms, using lime, and setting your mowers high. Paul talks about his earthworm habitat idea to deepen the soil. Paul sees permaculture purpose in having some lawn. He talks about planting things like crocuses, Roman chamomile, and yarrow for a mowable meadow. Paul talks about mowing and watering."
I'm not much into lawns myself, but a lot of this information is equally applicable to pasture management so I'd recommend it for everyone to listen to.
