Looks Good! Based on all of the previous correct responses, you would think biosolids enhanced his soil. The soil was originally poor in terms of fertility (based on the sedimentary parent material), a new O Horizon is present which should promote good crop growth due to increased microbial activity and nutrient release, and the A Horizon has been affected by biosolids addition. The A Horizon more than likely contains more organic matter and due to enhanced microbial activity will also contribute to increased nutrient release for plant growth.
