Modeling of runoff water and runoff pesticide concentrations in upland bare soil using improved SPEC model

Abstract: The SPEC model (Predicted Environmental Concentrations in agricultural Soils) was developed and improved for the simulation of pesticide runoff. The model was applied to the Sakaecho upland bare soil field (Tokyo, Japan) to predict runoff water, sediment concentration in runoff water, pesticide concentrations in runoff water, and runoff sediment (clothianidin and imidacloprid) under artificial rainfall conditions. The results showed that the simulated time to first runoff agreed very well with the observed dat… Show more

“…Bare soil, commonly used in low rainfall areas, allows the rainfall water to drag with it the PPPs losses remaining on the topsoil without any obstacles and can even be simulated and modelled (Thinh et al, 2019). Moreover, erosion and nutrient loss in bare soil would be more pronounced due to torrential rainfall events that are expected to be more recurrent due to climate change (IPCC, 2014).…”
