Manures behave similar to superphosphate in phosphorus accumulation in long-term field soils
Repeated application of manures to agricultural soils could cause the accumulation of phosphorus (P) in soils. However, it is unclear if manure P can behave similar to P in soluble fertilizers in accumulation Olsen-P (0.5 mol L-1 NaHCO3 at pH 8.5) in soils. A long-term wheat-maize rotation experiment was conducted to investigate the effects of repeated application of manures on P accumulation i...
متن کاملCarbon storage in seagrass soils: long-term nutrient history exceeds the effects of near-term nutrient enrichment
The carbon sequestration potential in coastal soils is linked to aboveground and belowground plant productivity and biomass, which in turn, is directly and indirectly influenced by nutrient input. We evaluated the influence of longterm and near-term nutrient input on aboveground and belowground carbon accumulation in seagrass beds, using a nutrient enrichment (nitrogen and phosphorus) experimen...
متن کاملPrimary Productivity in a Nutrient-Limited Tropical EstuaryI
The results of a survey of phytoplankton productivity, chlorophyll a and nutrient concentrations in Pala Lagoon, American Samoa, are shown to be interpretable in terms of two regimes: an ocean-dominated region where productivity is controlled by fix~d nitrogen concentrations, and a land-runoff-dominated regime where productivity is unrelated to major nutrient concentration. A quantitative relat...
متن کاملImmediate and long-term nitrogen oxide emissions from tropical forest soils exposed to elevated nitrogen input
Tropical nitrogen (N) deposition is projected to increase substantially within the coming decades. Increases in soil emissions of the climate-relevant trace gases NO and N2O are expected, but few studies address this possibility. We used N addition experiments to achieve N-enriched conditions in contrasting montane and lowland forests and assessed changes in the timing and magnitude of soil N-o...
متن کاملEstablishment of Long-term Soil Productivity Studies on Acidic Soils in the Interior Douglas-fir Zone
A clear understanding of the impacts of forest practices on long-term soil productivity is required to maintain the productivity of forest soils while forests continue to be managed for timber production. Although current regulations governing soil conservation in British Columbia are partially based on historic and ongoing research, there are few clear and unambiguous long-term results. The ne...
