“…Wheat straw was more effective at immobilizing N than the mineral ®bre in spite of a narrower C : N ratio. These observations support the views of Vinten et al (1998) that C : N ratios of amendment materials alone are not suf®cient to predict immobilizing capacity accurately. In our experiments and those reported above, C was evidently still in an available form to support the growth of micro-organisms in materials with very wide C : N ratios, such as compactor waste.…”

“…Recent ®eld studies have suggested that short-term rates of N mineralization and subsequent NO 3 ± leaching can be minimized by the incorporation of paper waste along with crop residues (Vinten et al 1998). These results demonstrated that there is scope to develop novel strategies for crop residue management based on the addition of substrates to in¯uence directly the activities of the decomposer organisms.…”

“…These compare with emissions of up to 67 g N 2 O-N ha ±1 day ±1 from ®eld soils after lettuce residues had been incorporated (Baggs et al 2000). Vinten et al (1998) measured mean losses of 25 and 13 g N 2 O-N ha ±1 day ±1 following incorporation of lettuce residues or cultivation, respectively, over a 60-day period. In Vinten's experiments, the application of paper-mill waste did not signi®cantly reduce emissions.…”

Abstract. A potential technique for reducing overwinter leaching from high N containing crop residues is to immobilize the N released during decomposition by co-incorporating materials of a wider C : N ratio. This article describes the use of laboratory incubation experiments to investigate the effects of a wide range of such amendment materials on the mineralization of N from sugar beet and brassica leaf residues in a sandy loam and a silt loam. These materials were of varying quality, with C : N ratio ranging from 15 : 1 to 520 : 1, and cellulose content from 0 to 34%. Amendments were added at a ®xed rate of 3.5 mg C g ±1 of dry soil, equivalent to around 10 t ha ±1 C (to 20 cm depth). The soils were then incubated at 15°C, and net mineral N derived from the leaves was measured at regular intervals over 168 days. Net mineralization of residue N was greatest with molasses (C : N ratio of 18 : 1), whereas paper waste (C : N ratio of 520 : 1) reduced N mineralized by up to 90% compared with a soil-only control. As the concentration of cellulose and lignin in the amendment materials increased, so the amounts of N mineralized decreased, with 62 and 54% of variance in N mineralized explained by cellulose and lignin content, respectively. Reduced levels of mineral N were associated with higher levels of biomass-N. The levels of N 2 O-N lost from sugar beet residues on day 14 were signi®cantly reduced from 66 to 5 g ha ±1 where compactor (cardboard) waste had been mixed into sandy loam, but this effect was not observed in the silt loam. These techniques could lead to greater ef®ciency of N use in rotations through reduction in N losses, and provide alternative routes for disposal of wastes when the EC Land®ll Directive is implemented.

“…Agricultural activities such as cattle farming can have a significant impact on nitrate (NO − 3 ) leaching and groundwater pollution (Ball et al, 1979;Field et al, for microbial denitrification and/or N immobilization or by increasing the presence of anaerobic microsites (due to soil pore blocking from solids of DE or increased microbial activity), which favors denitrification (Parkin, 1987;Aulakh et al, 1992;Hojberg et al, 1994;Paul and Clark, 1996;Drury et al, 1998;Vinten et al, 1998Vinten et al, , 2002. Contrary, compared to DE, urea applied to grazed pasture does not markedly change the soil C content or moisture.…”

Loss of nitrate (NO − 3 ) from grazing land is a major cause of surface and groundwater contamination. These losses increase when N sources such as fertilizer are applied to grazing land. The objectives of this work were to (1) study the impact of dairy effluent (DE) or urea on N losses and plant uptake when DE or urea was applied with and without cattle urine and; (2) determine the effect of organic C rich DE on the fate of urine N. The experiment was conducted using lysimeters that contained Templeton sandy loam soil extracted from a pasture in New Zealand. Application of DE resulted in significantly less ( p < 0.05) NO − 3 leaching compared with urea in the first year, but not in the second year. Differences between years could be attributed to the comparatively lower C:N ratio of applied DE in the second year, causing relatively greater N mineralization and greater NO − 3 leaching. Differences could also be due to cumulative effects of DE (first year applied) on second year NO − 3 leaching. Total annual pasture N uptake was similar for DE and urea treatments. During the first year, the average NO − 3 concentration was lower when DE was combined with urine compared to urine alone, but not in the second year. The combination of DE with urine resulted in significantly greater ( p < 0.01) annual pasture N uptake compared with the urine alone treatment in both years. Urine plus urea resulted in the greatest leaching losses in both years, but its impact on pasture N uptake was mixed. The total leaching loss of N from urine plus DE (90 kg N ha −1 ) was similar to urine alone (77 kg N ha −1 ) in the second year. Likewise, the annual percentage of 15 N recovered in the leachate from urine plus DE (9%) was not significantly different from urine alone (6%). However, 15 N recoveries revealed that the contribution of urine N to NO − 3 leaching was greater when urine was combined with DE (98.8%) compared to urine alone (83%). The greater NO − 3 leaching from urine when combined with DE could be a result of greater nitrification due to the low C:N ratio of DE. Additionally, the annual percentage of urine N uptake by the pasture from urine plus DE (29%) was significantly less than from urine alone (39%) ( p < 0.01). The application of organic C rich DE had no significant effect on soil N retention or denitrification when combined with urine.

“…The soil sink of nitrogen is related to immobilization mechanisms, which also remains poorly understood (TorresCañabate et al 2008), and may be associated with the presence of organic matter and biotic and abiotic immobilization (Vinten et al 1998;Torres-Cañabate et al 2008). Therefore, the addition of organic wastes and the use of inorganic residues for soil rehabilitation and quarry restoration can affect or control the nitrogen leaching into the nitrate vulnerable zone for waters (Vinten et al 1998;Jordán et al 2006;Santibánez et al 2007).…”

Nitrogen compound pollution associated with the use of sewage sludge compost and limestone outcrop residue under saline irrigation

Purpose The use of composted sewage sludge and limestone outcrop residue in land rehabilitation, soil improvement, and technosol making can influence the mobility of nitrogen compounds in groundwater. Materials and methods This experiment analyzed this source of possible pollution under an experimental design based on the use of columns (0-30 cm) formed by both wastes and a heavy irrigation regime. Two waters of different quality (saline and non-saline) were used for irrigation. The presence of nitrate, nitrite, and ammonium in the leachates was checked. Results and discussion The environmental risk due to the presence of nitrogen species associated with the use of these materials was very low in general, although nitrate was the most important compound affected by the use of sewage sludge compost and saline water. Conclusions The combination of saline water for irrigation with the compost has to be seriously considered as a source of pollution for surface and ground waters, and the use of both resources may be a key factor to be studied (low-quality water and sewage sludge compost).
