Here's one piece of it.
Livestock are a key part of regenerative farming. After we harvest the main crop, we graze livestock in the off-season.
In the wild, herbivores typically graze in herds. They eat grasses down almost to the ground, and their hooves mix manure and urine into the soil.
This benefits the soil by incorporating powerful nutrients so that the grasses grow back strong and healthy.
With managed grazing, we replicate this behavior in a controlled way on our cropland.
After harvest, we grow a "cover crop" which continues nourishing the soil with gases, fungi, and the soil biome. The sheep graze on the cover crop, simultaneously replenishing the soil with manure and urine.
All of this works together to feed our food crops in the spring - reducing our need for chemical fertilizers. Once the sheep have grazed down an area, we move the fencing to a new location so they can start all over again.
The sheep of course provide meat, so we get more productivity out of land.
Thinking bigger- instead of cutting down rainforests to make room for cattle, let's graze them on the same land where we grow food. And push chemical fertilizers out of the equation.
