Soil is the foundation for all life and every farm needs good, fertile soil to produce healthy crops. While soil only covers 10% of our Earth’s surface, most people don’t realize how important to life it is. Soil is a living, breathing world that supports all life on earth. Healthy soil is made up from approximately 45% minerals (clay, silt and sand), 25% air, 25% water and 5% organic matter (decomposing animals and plants). All of these ingredients, together with climate, affect the soil composition and how well the soil produces.
