Pesticide mixtures in soil: a global outlook
This data set includes four global maps of aggregated pesticides: (1) the total pesticide content in the topsoil of global croplands expressed in the unit of mg/kg-soil; (2) the number of pesticides detected in the topsoil; (3) the pesticide leaching rate to below the root zone expressed in the unit of mg/m2/year; and (4) the number of pesticides that exceeded a leaching rate of 1 mg/m2/year. This data set also includes two zip folders containing the topsoil residue and leaching rate of individual pesticide substances in nine different cropping systems. The surface area of the nine cropping systems can be obtained from the PEST-CHEMGRIDS dataset (Maggi et al., 2019).
A zip folder containing an example of input files required to run the model is attached together with this data set. Details of the methods used to produce these maps and the tabulated data can be found in Tang F.H.M and Maggi F. (2021). Pesticide mixtures in soil: a global outlook, Environmental Research Letters.
