Table 3.
Impact score (IS, in units of PAF m3 d/kgapplied) of the average scenarios with a cover crop for each environmental compartment (continental: rural air, freshwater, natural soil, and agricultural soil), for the two scenarios: tomato and grapevine and %‐change (Equation 17) when not using a cover crop (i.e., bare soil), for the application of two pesticides (mancozeb and pyriproxyfen). Calculation of %‐change = [(IS_without_cover – IS_with_cover)/IS_with_cover] × 100
| Emission distribution and cover crop fate | Crop | IS Rural air | IS Freshwater | IS Natural soil | IS Agricultural Soil | Total |
|---|---|---|---|---|---|---|
| Initial distribution—with cover exported from the field* | Tomato | 21 (<1%) | 18 (−2%) | 10 (1%) | 201 (113%) | 251 (91%) |
| Grapevine | 26 (<1%) | 80 (−1%) | 11 (1%) | 214 (103%) | 331 (66%) | |
| Secondary emissions—cover exported from the field* | Tomato | 21 (<0.1%) | 18 (−) | 10 (−) | 189 (111%) | 238 (88%) |
| Grapevine | 26 (<0.1%) | 79 () | 11 (−) | 209 (100%) | 326 (64%) | |
