First-year effects of rootraking on available nutrients in Piedmont Plateau soils
The effects of rootraking on the levels of Ca, Mg, K, PO4 and Na and on infiltration rates in Piedmont Plateau soils were investigated. Soil samples were taken before and after treatments at lo-foot intervals along permanent 100-foot lines located on the ridge, upper slope and lower slopes. Samples were taken at O-2, 2-4, 4-6, 6-12, 12-2018 and 18-24 in. depths and composited. Infiltration rates were measured with a double-ring infiltrometer. There was a general tendency toward nutrient increase at almost all depths with some differences significant at the 5 and 10% levels. A major increase in the PC4 content was found at the 4-6 and 6-2012 in depths. Infiltration rates decreased.
