Effect of plastic mulch on water flow and herbicide transport in soil cultivated with pineapple crop: A modeling study

Original language description

In Hawaii, pineapple is typically grown in raised beds covered with impervious plastic mulch. Field measurements of a commonly used herbicide (bromacil) mass beneath mulch-covered pineapple beds and inter-bed open areas revealed that open areas containeda mass of bromacil about 3.5 times greater than was originally applied, based on label instructions, to the entire field. The objective of this study was to evaluate the impact of surficial management on water dynamics and bromacil concentration in thesoil on a pineapple plantation using the flow and transport models. In our simplified approach, the water and solute boundary fluxes for the non-covered areas were increased to simulate the water and solute contribution from the plastic mulch surface. Reasonably good agreement between the model-predicted and observed soil water potentials and bromacil concentration profiles was obtained. Biased 1D and 2D results were predicted when the water runoff from plastic mulch was neglected.
