| Category | Indicator | Units |
| Soil quality | (1) Total organic carbon (TOC) | Mg/ha | (2) Total nitrogen (N) | Mg/ha | (3) Extractable phosphorus (P) | Mg/ha | (4) Bulk density | g/cm3 |
| Water quality and quantity | (5) Nitrate concentration in streams (and export) | concentration: mg/L; export: kg/ha/yr | (6) Total phosphorus (P) concentration in streams (and export) | concentration: mg/L; export: kg/ha/yr | (7) Suspended sediment concentration in streams (and export) | concentration: mg/L; export: kg/ha/yr | (8) Herbicide concentration in streams (and export) | concentration: mg/L; export: kg/ha/yr | (9) Peak storm flow | L/s | (10) Minimum base flow | L/s | (11) Consumptive water use (incorporates base flow) | feedstock production: m3/ha/day; biorefinery: m3/day |
| Greenhouse gases | (12) CO2 equivalent emissions (CO2 and N2O) | kgCeq/GJ |
| Biodiversity | (13) Presence of taxa of special concern | Presence | (14) Habitat area of taxa of special concern | Ha |
| Air quality | (15) Tropospheric ozone | Ppb | (16) Carbon monoxide | Ppm | (17) Total particulate matter less than 2.5 μm diameter (PM2.5) | μg/m3 | (18) Total particulate matter less than 10 μm diameter (PM10) | μg/m3 |
| Productivity | (19) Aboveground net primary productivity (ANPP)/Yield | gC/m2/year |
