In these four case studies from Iowa, Missouri, and Illinois, corn and soybean farmers present detailed, year-by-year budget data on their adoption of cover crops or no-till.
Each case study uses partial budget analysis to measure yearly changes in income that the farmer attributes to adoption, compared to a pre-adoption baseline:
- Planting costs increased by up to $38 per acre
- Fertilizer costs decreased by up to $50 per acre
- Erosion repair costs decreased by up to $16 per acre
- Yields increased by up to $76 per acre
Yearly net change in income ranged from -$83 to $110 per acre. If conservation incentives were included, net change ranged from -$33 to $150 per acre.
