By Jung, W K; Kitchen, N R; Anderson, S H; Sadler, E J ABSTRACT: Plant water and nutrient use for claypan soils are restricted by an argillic horizon (clay content > 500 g kg^sup -1^) that typically occurs 20 to 40 cm (8 to 16 in) below the soil surface.

ABSTRACT The objective of this study was to identify the main sources of variation in pesticide losses at field and catchment scales using the dual permeability model MACRO.

ABSTRACT Understanding relationships between sensor-based measurements and soil properties related to soil quality may help in developing site- specific management.
