Inactivation of HuNoV GII and Tulane virus in sandy soil plus plant and sandy soil-only control samples over 29 weeks at 12 °C, quantified using RNase RT-qPCR (n = 3). Fitted values from the joint reparametrized log-linear models are represented as dashed lines for the soil plus plant sample and dot-dashed lines for the soil-only control sample. Shaded areas represent 95% confidence intervals. Dotted lines indicate the detection limits of 2.15 log10 GC/g for HuNoV GII and 3.78 log10 GC/g for Tulane virus.
