We will contrast yield and yield risk, profitability, and soil remediation of miscanthus and switchgrass cropping systems (including switchgrass+legumes) with grain crops on marginal and vulnerable areas within the BCAP areas of MO and AR. Studies will include plot and field-scale evaluations on sites with various degrees of soil degradation. Proposed research will leverage and enhance funded and unfunded studies already initiated. Indicators of soil remediation will include soil organic C, infiltration, and soil biological activity. Funding will allow additional sampling and in-field measurement to be conducted at representative locations within BCAP fields to quantify soil and landscape properties and yield. Miscanthus establishment, early-stand growth, and first-year production will be measured and relationships developed with soil and landscape properties. This BCAP field sampling will also provide a critical baseline “picture” of soil condition that will be needed for understanding the long-term impact of switchgrass and miscanthus bioenergy crops.
