If you’re worried about drought resistance in your garden, composting is an excellent solution. By improving water retention, you can help support the growth of your plants even during dry spells.

Reduced Soil Erosion

soil erosion

Soil erosion is a major concern for any gardener or farmer. When the topsoil is lost, it takes years to build it back up to support healthy plant growth. Composting can help prevent soil erosion by improving soil structure. When you add organic matter to the soil through composting, it creates a stable environment, preventing erosion caused by wind or water. This also helps to preserve valuable topsoil for healthier plants and a more fruitful yield.

Not only does composting help control erosion, but it also supports land conservation efforts – a way to give back to our planet.

Soil Erosion Rates

Land Type Erosion Rate
Highly Erodible 15-30 tons per acre per year
Moderately Erodible 5-15 tons per acre per year
Slightly Erodible Less than 5 tons per acre per year

These rates are estimates of soil loss due to erosion caused by wind and water for the United States. As you can see, composting is an essential practice for controlling erosion rates, helping to preserve valuable topsoil and reduce the amount of soil loss.

Weed Suppression

Are weeds taking over your garden? Composting provides a natural solution for weed control. Compost has weed-suppressing properties that hinder the growth and spread of weeds, without the need for harmful herbicides. By adding compost to your garden, you create a more competitive environment, where plants thrive, and weeds struggle to survive.

Organic gardening is all about minimizing the use of synthetic products and relying on natural alternatives. Composting offers an eco-friendly approach to weed control that supports healthy soil and plant growth.

Reduced Need for Chemical Fertilizers
