Harvesting a winter rye energy cover crop (Secale cereale L.) could help sustain growing food and demand, provide new revenue streams, enhance ecosystem services without inducing land-use change. A two-year field experiment with three planting methods N fertilization rates (0, 60, 120 kg ha−1) that produced >5.0 Mg ha−1 yr−1 of biomass was evaluated for (1) fresh anaerobically digested forag...

The objective of this study was to evaluate the use calcium oxide (CaO) on nutritive profile, digestibility, and carbohydrate fractionation three sugarcane (Saccharum officinarum hybrids) genotypes: IAC-862480, SP-791011, CTC-3. Four CaO levels (0, 1.5, 3.0, 4.5% a fresh matter basis) were used in 3 × 4 factorial scheme, whose factors genotypes four oxide. chemical composition, fractionation, t...

Native meadows are widely used by producers in southeast Kansas. However, there few studies about management practices to improve agronomic performance This study evaluated the spring burn effect combined with application of lime, nitrogen, phosphorus, and potassium on yield forage quality native meadows. Yield were not affected lime application, or P K fertilization first year study. N increas...

Coastal lagoons are a common land-margin feature worldwide and function as an important filter for nutrients entering from the watershed. The shallow nature of lagoons leads to dominance by benthic autotrophs, which can regulate benthic–pelagic coupling. Here we demonstrate that both microalgae and macroalgae are important in controlling dissolved inorganic as well as organic nitrogen (DIN and ...

Uptake of nutrients and organic C was measured once annually between 2000 and 2002 in each of 10 streams within the water-supply source areas for New York City. Nutrients (PO4 3– and NH4 þ) and organic C (glucose and arabinose) were injected into the streams for 1 to 2 h, and uptake lengths were estimated from the longitudinal declines in downstream concentration relative to that of a conservat...

The marine biogeochemistries of carbon and nitrogen have come under increased scrutiny because of their close involvement in climate change and coastal eutrophication. Recent studies have shown that the high-temperature combustion (HTC) technique is suitable for routine analyses of dissolved organic matter due to its good oxidation efficiency, high sensitivity, and precision. In our laboratory,...
