Animal systems can be used to clear gardens for permanent systems, or they can be used as part of system cycles to rip up organic matter, eat insects, eat weed seeds, and increase fertility. All the while the animals are doing what they love to do while also providing eggs and meat.
Here, at Zaytuna Farm, we are cell grazing with cattle inside of swale trenches and Muscovy ducks on top of swale mounds.
Ducks, chickens, geese, and turkeys can all be used similarly to the Muscovies. Larger animals like cattle need to be very carefully managed with rotational grazing to prevent damaging the system.
