Soil enrichment

In this photo you can see the dung of animals covering the open soil. Next to the grasses you will see
is the layer of dung that will eventually start to disintegrate and prepare a bed where other grasses can start to grow and cover the soil.
It will also break the speed of raindrops and it will prevent the soil to be impacted by the rain.
It ake some time for nature to improve soil but there is a well established system.
