Tillage, Nitrogen, and Cropping System Effects on Soil Carbon Sequestration
With increased cropping intensity, one would expect that more crop residue and C would be added to the Soil C sequestration can improve soil quality and reduce agriculsoil than with a crop-fallow system (Campbell et al., ture’s contribution to CO2 emissions. The long-term (12 yr) effects of tillage system and N fertilization on crop residue production and 1995, 2000b; Janzen et al., 1998a; Pete...
متن کاملSoil Carbon Dioxide Emission as Influenced by Irrigation, Tillage, Cropping System, and Nitrogen Fertilization
Soil and crop management practices can influence CO2 emission from crop and grasslands and therefore on global warming. We examined the effects of two irrigation systems (irrigated vs. non-irrigated) and six management practices [no-till malt barley (Hordeum vulgaris L.) with 67 or 134 kg N ha (NTBFN), notill malt-barley with 0 kg N ha (NTBON), conventional-till malt barley with 67 or 134 kg N ...

iNTroducTioN The discharge of reactive nitrogen (N) and phosphorus (P) into water bodies is unwanted as it accelerates the process of eutrophication. To avoid discharge of these nutrients, energy and resources in the form of aeration (for nitrification), organic carbon (for denitrification and/or enhanced biological phosphorus removal (EBPR)), and chemical precipitants (e.g., ferric, alum, lime...

15 صفحه اولTrapping phosphorus in runoff with a phosphorus removal structure.
Reduction of phosphorus (P) inputs to surface waters may decrease eutrophication. Some researchers have proposed filtering dissolved P in runoff with P-sorptive byproducts in structures placed in hydrologically active areas with high soil P concentrations. The objectives of this study were to construct and monitor a P removal structure in a suburban watershed and test the ability of empirically...
