Carbon (%) and Nitrogen (%) represents the total carbon and nitrogen of the soil sample. Each data point represents the mean of three experimental replicates (n = 3). Here, H represents the headland area with no past history of pesticide application and R represents the farm site with past history of pesticide application.
