Soil carbon and nitrogen accumulation with long-term no-till versus moldboard plowing overestimated with tilled-zone sampling depths
Autor: Eileen J. Kladivko, Tony J. Vyn, William W. McFee, Anita Gál, Erika Michéli
Publikováno v: Soil and Tillage Research. 96:42-51
Numerous investigators of tillage system impacts on soil organic carbon (OC) or total nitrogen (N) have limited their soil sampling to depths either at or just below the deepest tillage treatment in their experiments. This has resulted in an over-emp

Crop yield and rooting as affected by fragipan depth in loess soils in the southeast USA
Autor: J.G Graveel, Donald D. Tyler, William W. McFee, J.R Jones
Publikováno v: Soil and Tillage Research. 68:153-161
The combination of soil erosion and restrictive subsurface features can adversely influence root growth and crop productivity. The effects of depth to a restrictive layer on yield and root development were determined for soybean ( Glycine max (L.) Me

Publikováno v: Environmental sciencetechnology. 16(3)
Acid precipitation, including dry deposition, is recognized as coming from pollution-caused strong acid precursors that result from the burning of fossil fuels. Recent studies suggest that ecosystems susceptible to acidification occur over the entire

Fertilization of Southern Pines at Establishment
Autor: William W. McFee, H. Lee Allen, Eric J. Jokela
Publikováno v: Forest Regeneration Manual ISBN: 9780792309604
Fertilization is a silvicultural practice used for increasing forestland productivity in the southern U.S. Effective operational use of fertilizers requires diagnostic systems, used individually or in combination, that accurately identify site nutrie
