“…While the hydroponic cultures were aerated, marsh sediments are generally anoxic (Teal and Kanwisher 1961), and it is well established that maximum nutrient uptake rates are dependent upon an adequate supply of oxygen to the roots (Vlamis and Davis 1944, Hammond et al 1955, Hopkins 1956).

“…There are a number of conditions that can modify nutrient uptake kinetics such as an oxygen deficiency in the root zone. While the hydroponic cultures were aerated, marsh sediments are generally anoxic (Teal and Kanwisher 1961), and it is well established that maximum nutrient uptake rates are dependent upon an adequate supply of oxygen to the roots (Vlamis and Davis 1944, Hammond et al 1955, Hopkins 1956). Even plants adapted to waterlogged soils, such as Spartina, that are able to supply oxygen internally to the root system (Mitsui 1965, Teal and Kanwisher 1966, Armstrong 1967 have uptake mechanisms that are sensitive to the oxygen status of the root zone (Rao and Mikkelsen 1977).…”

Rates of nitrogen uptake were measured in cultures of Spartina alterniflora growing outdoors in continuously flowing nutrient solutions. A Michaelis-Menten model with as an exponential function of temperature was an accurate predictor of uptake rates dunng the growmg season. Half-saturation constants were estimated to be 0.057 ± 0.016 mg N/L for NH. 0.124 ' != 0.034 mg N/L for N0 3 • These half-saturation constants are too low in comparison to levels of morgamc NH 4 in marsh pore water to account for nitrogen-limited growt_h in field. It was suggested an edaphic factor(s), possibly an oxygen deficiency, or a metabolic pOison as H 2 S, or from other ions for carriers, might inhibit nitrogen uptake in the marsh m such a way as to mcrease the half-saturation constant for uptake. A gradient of such an environmental factor could account for gradients in morphology and productivity in communities of Spartina alterniflora.

“…The sampling method has been widely used and described to obtain a representative sample of soil air (Shapiro et al 1956;Yamaguchi et al 1962;Lal and Taylor 1969;Zainol et al 1991), and is appropriate for greenhouse studies (Yamaguchi et al 1962). However, soil air samples from field plots can be collected by several other methods (Hack 1956;Hammond et al 1955;Dasberg and Bakker 1970;Davidson et al 1986). The air samples collected at four stages were analyzed isothermally for N 2 O concentration with Shimadzu GC 2014 gas chromatograph fitted with an electron-capture detector.…”

Application of nitrogenous fertilizers in agriculture is a major source of anthropogenic N 2 O emission. Choice of nitrogenous fertilizer with a low emission potential can reduce global nitrous oxide (N 2 O) emissions. We studied effects of urea (U), ammonium nitrate (AN), sulfur-coated urea (SU), and compost (C) application on the concentration of N 2 O in soil air of mesic Typic Hapludalfs and corn ( Zea mays L.) growth in a greenhouse experiment conducted at The Ohio State University. In the urea-treated soil, N 2 O concentration (2.35 μl l −1 ) increased significantly (p = 0.05) over that in the unfertilized soil (0.21 μl l −1 ). The increase in N 2 O concentration for AN, SU, and C treatments over the unfertilized soil was 748%, 681%, and 48%, respectively. Soil treated with mineral fertilizers produced significantly (p = 0.05) higher N 2 O concentration in comparison with that in the unfertilized and compost-treated soils. The highest shoot biomass of 52.8 g pot −1 was recorded in SU-treated soil and the lowest of 33.4 g pot −1 in unfertilized soil. Soil treated with SU produced the highest root biomass (59.0 g pot −1 ) followed by that for AN (54.7 g pot −1 ), U (53.7 g pot −1 ), and C (36.7 g pot −1 ), and the lowest root biomass was recorded in the unfertilized soil (33.2 g pot −1 ). The highest and the lowest root volume were recorded in soil treated with SU (357 cm 3 ) and unfertilized soil (177 cm 3 ), respectively. The slow-release fertilizers 95 96 G. S. Dheri et al. (i.e., sulfur-coated urea) lowered concentration of N 2 O in the soil air.
