These bright green strips represent areas where our pastured poultry grazed in previous seasons. The added nitrogen from the chicken manure fertilizes the grass which spurs on extra vegetative growth.
The next year, when the chickens roam over the tall grass, the vegetation gets matted down against the soil where the soil biome can go to work breaking it down into organic matter.
The matted down grass shades and protects the soil while the increased organic matter soaks up and holds on to more precious water from our infrequent summer rains.
The next year, the cycle repeats and the soil health gets better and better. This wet spring, you can hardly walk through the first flush of annual grasses.
What started as marginal range with thin, mineral, desert soils sparsely populated with some annual grass and scattered forbs has over time become productive pasture. In time, we may inter-seed with more perennial grasses or co-graze sheep and cattle with the chickens to further build the soils.
For now though, the chickens are just doing their thing!
