 The large canopies of many trees help to prevent soil erosion by reducing the impact of rain onto the ground. The water drains down the leaves and branches and soaks into the soil rather than forcefully hitting the ground, which decreases the amount of soil that is washed away with the rain. Trees reduce the rate of erosion by: protecting the soil from the impact of rain. transpiring large amounts of water, which counteracts very wet soil. binding soil to sloping land with their roots. Use leaves, straw, or coarse compost around kitchen garden plants instead. Cover bare patches of soil, hill sides, and spaces between plants with 1 to 2 inches of mulch. This will protect soil from overhead watering and rain, keeping it in place. It also minimizing evaporation and feeding soil at the same time.
