Cultivated soil water dynamics with many Hydrus 1D simulations using R

Data and R code bundled here provide a framework to implement the open source Hydrus-1D soil water model to characterize influence of crop rotation, weather, and soils on root zone water flux in a non-irrigated annual cultivation agricultural system. Simulated water flux is combined with soil nitrate concentrations averaged by 2-year rotational sequence to produce nitrate leaching estimates. This framework and the associated results are the analytical underpinning of a paper in revision at the journal of Agricultural Ecosystems & Environment. Included are all data necessary to run the simulations, code to run the simulations (Hydrus 1D software required - see Related Resources for archived version used), code to aggregate/plot the results, and all of the results.
