Regenerative grazing principles

The farmers we surveyed made it clear that success require more than just changing a few practices. Much of their learning had been about changing their mindset and and individual behaviours in order to observe and adapt their management.

These have been captured below in the form of key behaviours nested under three high level regenerative grazing principles:

---

#1 Allow pastures to recover

(1a) Ensure pastures are fully recovered before grazing

• A plant is considered ‘recovered’ once it has grown and photosynthesised enough to replenish its root reserves, and looks like an ungrazed plant.

• Allowing full pasture recovery maximises year-round photosynthesis and the pumping of liquid carbon into the soil via root exudates. These exudates feeds the soil microbiome in exchange for nutrients, water etc.

• Pastures that are allowed to recover are less stressed and adapt to maintain quality at higher covers.

(1b) Manage for vegetative growth and high animal performance

• Managing for vegetative growth means grazing before plants go into their reproductive phase.

• This maximises animal performance in the growing season.

• When pasture growth exceeds feed demand, some paddocks are deferred as stockpiled feed or shut up for hay/baleage

(1c) Increase grazing density to achieve more even grazing (or trampling)

• More even grazing ensures most plants are ‘reset’ into a vegetative growth phase. Increasing density (to a point) can achieve this without compromising animal performance.

• Animal behaviour shifts from selective to non-selective grazing.

• Enabled by investing in portable / permanent fencing and stock water, or by increasing mob size.

#2 Manage feed supply and demand with minimal external inputs

(2a) Carry higher pasture covers into the shoulders and non-growing seasons

• Helped by diverse pastures which can hold quality at higher covers.

• Allows longer rotations and reduced need for supplements while fully feeding stock year-round.

• Protects pasture recovery by giving farmers more time to adapt to unexpected slow (dry / cold) growth.

(2b) Make use of deferred grazing

• Like a hay / baleage paddock, species and fertility will affect deferred grass production and quality.

• Can be valuable as a low cost summer /winter ‘crop’.

• Carries a bulk stockpile of surplus grass into non-growing seasons.

(2c) Have flexible stock policies

• Allows feed demand to be more closely matched to pasture growth / reserves.

• Can make decisions early, de-stocking before feed becomes tight in order to protect pasture recoveries.

#3 Observe, identify and adapt

(3a) Improve observational skills

• Spend less time on tractors and motorbikes, and more time walking, shifting, watching.

• Optimise stock performance by monitoring gut fill, dung scores, coats, behaviour etc and adapting management in response.

• Observe pasture growth, leaf stage, pasture composition, colour, understory etc to see where grazing management enhances or degrades pasture performance.

• Observe and monitor soil health and how it’s impacted by grazing management (bare ground, plant spacing, surface texture, structure, rooting depth, worm counts, insect pests etc).

(3b) Identify and address limiting factors impacting performance

• Mineral deficiencies or imbalances, or soil compaction.

• Low soil biological activity.

• Lack of pasture diversity or sward density.

• Unsuitable stock classes.

• Inappropriate tools or infrastructure.

• Use of harmful agrichemicals, etc.

(3c) Embrace a regenerative mindset

• Invest in knowledge, ideas and trials, seeing failures as learning opportunities.

• Don’t get stuck in fixed ideas or prescriptions.

• Everything on the farm is interconnected, including the farmer.

• Don’t worry about what the neighbours think!
