Allen Williams: The World’s Loudest Voice on Adaptive Grazing

Allen Williams: The World’s Loudest Voice on Adaptive Grazing

We recently came across a very interesting interview with Dr Allen Williams in Acres U.S.A. Dr Williams is the founding partner of Understanding Ag, Grass Fed Insights, and a partner in Joyce Farms, Inc. He pioneered many of the early adaptive grazing protocols and forage finishing techniques. Today, Allen and his colleagues specialise in whole farm and ranch planning based on the concept of regenerative agriculture.

Dr Williams grew up on his family’s farm in the Piedmont Region of South Carolina. The farm was diverse, with beef cattle, pastured pigs, sheep and goats, chickens, turkeys, ducks and pheasants. They also grew extensive market gardens. The family farm didn’t use copious amounts of fertiliser, didn’t use pharmaceuticals, a lot of feed additives or fungicides or pesticides. 

In this article, we highlight key points from the interview with Dr Williams in Acres U.S.A:

Our soils and ecosystems have been severely degraded 

Although speaking from an American context, Dr Williams highlights that damaged soil and ecosystems are not just affecting rural communities, their health and their economies, but also leads to the production of foods that are not as nutrient-dense as they could be. 

All farmers should follow the six principles of soil health

  • Keep the soil covered – we need living roots growing in the ground to cover the soil and provide biological activity.
  • Minimise soil disturbance – These days, we’ve got giant equipment that’s creating more and more ways to disturb the soil quicker, releasing enormous amounts of carbon into the atmosphere. 
  • Increase crop diversity – Row-cropping operations lead to monoculture and low rotation diversity. 
  • Keep living roots in the soil year-round.
  • Integrate livestock – crop farmers should integrate livestock into everything that they do. 
  • Context –  If you do not understand your context, you can never be regenerative or develop healthy soil.

What is adaptive grazing?

Adaptive grazing is a system of grazing that allows farmers to rapidly adjust to changing conditions, allowing them to meet multiple goals and objectives all at the same time.  

This is in contrast to rigid rotational grazing that doesn’t work in real nature when you’re dealing with biology. 

Adaptive grazing isn’t just for cattle. It covers chickens, pastured pigs, lamb, sheep, goats; whatever species of livestock you want to add to the mix. 

Reversing the degradation of our soils by transitioning to regenerative agricultural practices

Dr Williams teaches farmers the six soil health principles, as well as what he calls the three principles of adaptive stewardship:

  1. Compounding
  2. Diversity
  3. Disruption

“That is your roadmap to rebuilding soil health and being truly regenerative and profitable,” he says.

What are the benefits of adaptive grazing?

  • Grazing properly creates dense, thick swards of forage with multiple plant species that are feeding biology in the soil
  • The mycorrhizal fungi and bacteria and all of the organisms that produce the biotic glues that aggregate these soil particles. 
  • When rain falls, instead of pounding, and pulling and running off, and taking topsoil, and nitrates and phosphate with it, it can now infiltrate into the soil and be retained in the rhizosphere and root zone in the soil. 
  • This enhances the health and fertility of the soil and leads to better yield and a more sustainable approach to agriculture. 

“When our cattle are grazing properly, they’re creating biology in the soil that aggregates soil particles so that the soil infiltrates and retains a lot more water. With proper livestock grazing, we are finding that we are actually recharging the aquifer and recreating natural springs that have dried up and disappeared. With adaptive grazing, we don’t have the erosion, the sediment leaching or the nitrate and phosphate leaching or runoff. And with every bite that livestock take, we’re creating incredible photosynthetic activity in those plants that is a magnet for more rainfall on that area and cycle more water there.” – Dr Alllen Williams
