“Winona” November 2008
![Page 3: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/3.jpg)
Winona in 2008• Myself and son Nick

• 4000 Merino sheep (time control grazed)
• 500 acres cropped annually (Pasture Cropped)
• 55 year-old Merino Stud.
• 30 year-old Kelpie working-dog stud

Industrialised agriculture on “Winona”:
• Destroyed our grasslands • Created weeds • Became unprofitable• Destroyed our resource base – soil• Created soil erosion• Created major dry-land salinity problems• Depleted our soil carbon
THE INDUSTRIALISED EXPERIMENT FAILED!
![Page 6: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/6.jpg)
I decided to restore Winona’s native
grasslands
• In 1992
![Page 7: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/7.jpg)
Why?The industrialised system was sending us broke!
The outcome was:
– Greater resilience– Increased species diversity– Improved soil health– Increased soil carbon– Enhanced ecological function
– INCREASED PROFITS

How did we do this?
![Page 9: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/9.jpg)
We changed grazing management
to Time Control Grazing
and cropping management to Pasture Cropping
![Page 10: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/10.jpg)
Pasture Cropping is a land management technique that
mimics the function of native grassland, where perennial and
annual species grow symbiotically and each benefits
the other
![Page 11: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/11.jpg)

Pasture Cropping
Grazing and cropping are combined and managed in a way
where each one benefits the other.
![Page 13: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/13.jpg)
Pasture CroppingZero till sowing of crops into perennial pasture.
• Never Never Plough.
• Never kill perennial species.
• Perennial pastures can be native or introduced.
• Weeds are managed by creating large quantities of thick litter by using correct grazing management of livestock.

Pasture Change on Winona since 1999
• Perennial native grass has increased from 10%-80%
• Native perennial diversity has increased from 12 to 50
species
• Weeds have decreased from 60% to 5% of the pasture
Research has shown Pasture Cropping will increase perennial grass seedling recruitment (Grain & Graze )

Bacteria have increased 3.5 times.
Fungi have increased 9 times
Protozoa have increased 10 times
Nematodes have increased 60 times
Increase in soil microbes (Soil food-web analysis March 2007)

Increase in insect numbers and diversityElise Wenden October 2007
• Insects numbers have increased by 600%
• Insect diversity has increased by 25%
![Page 24: Colin Seis: Regenerative Land Management at Winona](https://reader036.vdocument.in/reader036/viewer/2022081602/5562f31bd8b42a38778b5808/html5/thumbnails/24.jpg)
Organic Carbon
• Pasture Cropping and the recreation of a native grassland has improved soil organic carbon.
• On Winona soil carbon levels have increased from 1.8% in 1995 to 3% - 4% in 2006.

By increasing soil carbon and ecological function we have:
• Increased soil water-holding capacity (drought tolerance)
• Improved nutrient availability (reduce fertiliser)
• Increased plant, animal & insect diversity (resilience)
• Reduced plant disease (no fungicides)
• Reduced insect attack ( no insecticides)
• Increased soil-microbial numbers & diversity
• BECOME MORE PROFITABLE

Agriculture becomes more profitable,
regenerative, restores ecological function
& restores soil carbon
When agricultural practices function closer to Nature’s
original design
