To change the texture of silt loam soil to loam, the contractor would need to add sand to the soil and mix it well. Loam has a balance of sand, silt, and clay particles, and adding sand to a silt loam soil decreases the percentage of silt particles, creating a more balanced soil texture. Adding humus or compost would improve the soil's fertility and organic matter content but would not necessarily change the soil texture to meet the specifications for loam. Clay would increase the percentage of clay particles in the soil, making it more clay-like rather than loam-like.
