Two soil mixtures with different bulk densities (light and heavy) that are commonly used in horticultural and floricultural nursery crops (citrus, foliage plants, potted flowering plants, nursery fruit crops, bedding plants, and cut flower) will be selected. Under the simulator, the hydraulic properties will be determined for each selected soil sample. The hydraulic properties include: infiltration capacity, infiltration rate, saturated and unsaturated hydraulic conductivities. The USDA-EAH model will be modified to simulate water balance and nutrients and pesticides movement from containers that are above ground. The new module will be linked with the original EAHM. The seepage from the new modeule will be input to the USDA-EAH model. In this study, the new module will be evaluated using the collected data from the containers. The single event version of the model will be tested given initial conditions that are measured on bare containers.
