Answer: Loam soil typically contains the most organic matter compared to other soil types such as sandy, clay, or silt soil.
Explanation: Loam soil is a mixture of sand, silt, and clay in roughly equal parts, which creates a soil with good drainage and water-holding capacity, as well as high levels of organic matter. Organic matter in soil is important for plant growth as it provides nutrients, helps retain moisture, and improves soil structure. Loam soil is often considered the ideal soil type for many types of plants, as it offers a balance of drainage, water-holding capacity, and nutrients.
