TL;DR: In this paper, the authors quantify gross rates of internal N-cycling processes (i.e., mineralization, nitrification, and immobilization) from an unmanaged grassland, and investigate the role of topography and climatic factors on the spatial and seasonal variation of these processes.

TL;DR: In this paper, the effect of coal combustion by-products on soil test P (STP) was investigated and three widely available coal combustion flyash (FBC), flue gas desulfurization byproduct (FGD), and pulverized coal flyash was used.

TL;DR: Alum effectively reduced readily soluble P, determined in water extracts of moist manure samples with 1 h of shaking, for all three manures, and Sequential extraction results indicate that the by-product treatments shifted manure P into a less vulnerable fraction, NaHCO3 - P, while the alum treatment shifted the P into even more stable forms, mostly NaOH-P.

TL;DR: In this article, coal combustion by-products (CCBs) were applied to high P soils in zones of high surface runoff potential, where there is little erosion, has the potential to reduce P export without affecting crop production.

TL;DR: In this article, the authors examined denitrification in a grassed and wooded riparian ecotone common to the Valley and Ridge physiographic province in Pennsylvania, and found that the grassed site exhibited higher denitification rates than the wooded site.
