Healthy soil is composed of approximately 45% mineral matter, 5% organic matter, and 50% pore space containing air and water. Organic matter helps to improve soil structure and fertility, while mineral matter provides essential nutrients for plant growth. The pore space allows for water and air to move through the soil, which is important for root development and nutrient uptake by plants.
