    A harmonized dataset relating alternative farmer management practices to crop yield, soil organic carbon stock, nitrous oxide emissions, and nitrate leaching generated using IPCC methodologies and meta-analysesZenodo by Roberta Calone, Angela Fiore, Guido Pellis, Maria Luz Cayuela, Gabriele Mongiano, Alessandra Lagomarsino, Simone Bregaglio

    Published 2025-02-01
    “…., unique combinations of farming practices and pedoclimatic conditions, which have been associated with values of SOC changes, nitrous oxide emissions, nitrate-nitrogen leaching, and crop yield. To synthesize trade-offs and synergies between farming practices, each case scenario has been ranked with a ∑ommit index (∑i) value, a fuzzy-based measure ranging from 0 (bad) to 1 (good). …”
