Hydropedology is well positioned to address contemporary issues resulting from climate change. We propose a six-step process by which digital, field-scale maps will be produced to show where climate change impacts will be greatest for two land uses:

Slowly permeable transitional horizons separate soil and saprolite, but these horizons cannot be identified easily in the field. The objectives of this study were to determine why the soil-saprolite transitional zone (BC and CB horizons) is slowly pe

Subsoiling and slit tillage can increase root growth through subsurface hardpans. In-row subsoiling fractures a section of the pan below the row. Slit tillage cuts a 3-mm-wide slit through the pan with a thin blade mounted on a shallow subsoil shank.

Tillage pans occur in many coarse-textured soils and must be ripped by a form of deep tillage to maximize yields. This study compared the longevity of slits produced by subsoiling and slit-till (both to 16 in.) to a no-till treatment, and related sli

Saprolite is not permitted for use in on-site wastewater disposal in North Carolina if quartz veins occur within 60 cm (2 ft) of the septic trench bottom because such features might transmit raw sewage quickly to groundwater. This study evaluated the

Subsoiling is used to loosen root-restricting layers and increase rooting depth and water availability; however, little information is available regarding how to adjust the recommended fertilizer N rate. This study evaluated corn (Zea mays L.) grain
