A SUB-TILL SAPROLITE AND THE OVERLYING SOIL PROFILE NEAR MOUNT ORFORD, SOUTHERN QUEBEC

The effect of overlying tissue on the spatial sensitivity profile of near-infrared spectroscopy.

The exact volume of brain tissue interrogated in near-infrared spectroscopy (NIRS) studies of cerebral oxygenation in unknown, the inhomogeneity of the head and resulting variation in optical paths making determination of the interrogated volume difficult. In this study, the spatial sensitivity profiles in simple two-component inhomogeneous cylindrical models are predicted by Monte Carlo simula...

Differences in Soil Water Use, Lint and Biomass Yield in No-till and Conventionally Tilled Cotton in the Southern Piedmont

The southeast, despite its abundant rainfall, suffers short-term summer droughts with detrimental effect on crop yield. No-till production systems provide added insurance against such conditions by improving infiltration, and conserving moisture in drought-prone soils. In three years of experiment near Watkinsville, GA, no-till cotton treatments maintained higher soil moisture content, more veg...

Regional Study of No-Till Impacts on Near-Surface Aggregate Properties that Influence Soil Erodibility

Soil Carbon Stocks in Two Hybrid Poplar-Hay Crop Systems in Southern Quebec, Canada

Tree-based intercropping (TBI) systems, consisting of a medium to fast-growing woody species planted in widely-spaced rows with crops cultivated between tree rows, are a potential sink for atmospheric carbon dioxide (CO2). TBI systems contribute to farm income in the long-term by improving soil quality, as indicated by soil carbon (C) storage, generating profits from crop plus tree production a...
