Soil Health - the condition of the soil and its potential to sustain biological functions, maintain environmental quality, and promote plant, animal, and human health.
Cover Crops – a multi-functional crop that prevents erosion, improves soil physical and biological properties, supplies nutrients, suppresses weeds, improves water cycling, breaks pest cycles, and provides forage along with various other benefits.

Regenerative agricultureIs it a buzz-term?Is it a fad?Is it a marketing scheme?Is it the 2020 version of all-natural or sustainable or conservation?

Regenerative agriculture
Mid 1930s
“Land doctoring” versus the science of land health

Regenerative agriculture
“Those who live close to the earth – we farmers –have become as illiterate as anyone else when it comes to reading our landscapes.”
“Regenerative agriculture implies more than just ‘sustaining’ something but rather an active rebuilding or regeneration of existing systems towards full health.”

Regenerative Mindset
Ø Holistic manager (not just farm or land manager)Ø Prioritize soil healthØ Manage ecology – harvest sunlightØ Manage the underground “herd”Ø Keep biology in mind with each decisionØ Nurture symbiotic relationships

Regenerative Mindset
Ø Till soil only when absolutely necessaryØ Implement perennials as much as possibleØ Integrate (continuous living) cover crops into row cropsØ Use manure as a nutrient source as much as possible Ø Integrate livestock onto the landØ Scrutinize every off-farm input
How can we have a?
