“…Nitrogen uptake by rice plants was disproportionately greater in treated plots compared with the low rate plot (C195), at approximately 230% and 300% for the T450 and T600 treatments, respectively. The rate of nitrogen recovery by rice plants (32-67%) in this study was similar to that reported for bermuda grass treated with swine effluent (40-75%; Adeli et al 2003;Whalen and DeBerardinis 2007) but higher than the rate reported by Liu et al (1997) (13-32%) and Carey et al (1997) (20%).…”

A study was conducted to determine nitrogen budget and ammonia volatilization in Japanese paddy fields supplemented with liquid cattle waste (LCW). A series of four, 2×10 m experimental plots was established in a paddy field with silty clay soil planted with forage rice (Oryza sativa L.). In addition to 195 kg N ha −1 of chemical or compost-based basal fertilizer, LCW was applied as an additional fertilizer at total nitrogen rates of 0, 255, 255, and 405 kg N ha −1 to the four plots C195, T450-1, T450-2, and T600, respectively. The mass balance showed that after application of LCW, 32-39% of total input nitrogen was assimilated into aboveground parts of rice plants, 11-15% leached downward, 2.5-4.0% was lost via ammonia volatilization, 1.6-5.1% was retained in roots or was adsorbed onto soil, and approximately 30-40% was lost via denitrification. Compared to animal waste slurries applied to unsaturated soils, nitrogen loss via ammonia volatilization was relatively lower, probably due to the dilution effect of floodwater. Nitrogen loss via denitrification was markedly higher in areas where LCW was applied compared to areas without LCW application. On the other hand, nitrogen leaching downwards represented a substantial loss and may be an environmental concern. However, after LCW application only, the ammonium ion was detected, at a maximum nitrogen concentration of 11.4 mg L −1 . In this system, therefore, nitrogen has a different fate to that in animal waste slurries applied to unsaturated soil. In that situation, the major nitrogen form in leaching water is nitrate nitrogen, which moves readily into groundwater.

“…Adeli et al (2003) showed an overall recovery of 40% of waste-N following two applications of swine effluent over a growing season, but the maximum recovery of 51% was observed in the fall fertilization. Liu et al (1997) reported dry matter N recoveries of 13-32% over the course of a 2-year study in Alabama.…”

Over the past 15-years, swine-producing confined animal feeding operations (CAFOs) have proliferated throughout the Southeastern United States, particularly in North Carolina. Waste at these facilities is collected in open-air lagoons and the liquid phase is land-applied as fertilizer by sprinkler irrigation. Numerous investigations have focused on individual aspects of the fate of nitrogenous liquid waste, but none has attempted a comprehensive analysis of post-application transformations and losses. On three occasions, we experimentally applied liquid swine waste at typical industry doses of 1.2 and 2.5 cm-ha (40-130 kg N ha À1 ) to carefully defined plots in an active spray field on a representative North Carolina CAFO and constructed a nitrogen mass balance for the waste by assessing most N pools and transformations in post-application observation periods of 14-19 days. We consistently recovered more N than applied, by an average of 126%. This was likely due to mineralization of endogenous organic-N, a reservoir that was not measured. Plant assimilation clearly represented the most important N sink for this fertilizer type, accounting for 25-117% of the applied N. Offsite loss to leaching and volatilization and onsite accumulation in the inorganic phase and in microbial biomass all assumed secondary and roughly equal importance; each term represented about 5-20% of the applied N. Denitrification was inconsequential in N loss from a mass standpoint, accounting for 2% of the effluent. The post-application fate of N in liquid swine waste did not differ fundamentally from other organic and inorganic fertilizers, as the relative importance of all loss and storage terms fell within the ranges of values given for other fertilizers. However, liquid swine waste did differ from other N fertilizers in the rate of processing. Transformations occurred rapidly due to the immediate post-application contact of liquid swine waste-N with plant roots and microbes in a form (NH 4 + -N) immediately available for use.

“…Increases in crop yield from the contribution of N in livestock manure have been documented by various researchers (Beauchamp 1983;Xie and MacKenzie 1986;Montavalli et al 1989;Jokela 1992;Liu et al 1997;Schoenau et al 1998a). However, crop availability of total N in manure is generally lower than N contained in inorganic fertilizer because of the slow release of organically bound N and the volatilization of NH 3 from surface-applied manure (Klausner and Gust 1981;Beauchamp 1983).…”

Use of ion exchange membrane to assess soil N supply to canola as affected by addition of liquid swine manure and urea. Can. J. Soil Sci. 80: 213-218. A growth chamber study was conducted using two Saskatchewan soils to evaluate how addition of urea and swine manure affects the supply of plant-available nitrogen (ammonium and nitrate) and its relationship with plant N uptake. Treatments consisted of two different N rates applied as urea and manure (100 and 800 mg N kg -1 ) and a control. Ion exchange membrane probes were used to measure plant-available N supply rate. Canola was grown under the same environmental conditions to determine plant N uptake. Additions of fertilizer and manure significantly increased the supply of plant-available N measured in the soil. Over an 84-d period the available N supply in the manured soil was about 40% lower than in the urea-fertilized soil at equivalent rates of total N addition due to incomplete mineralization of organic N in the manure. However, plant N uptake was similar between manure and urea-treated soils, which was attributed to other nutrients present in the manure that may have enhanced root growth and plant N uptake. High proportions of ammonium N were measured initially, especially at the high rates of urea and manure. However, inorganic N in the form of ammonium rapidly decreased with time and nitrate N became the main inorganic N form supplied. Overall, there was good correlation (r value 0.79 to 0.96) between plant N uptake and available N supply rate in the soil as measured by ion exchange membrane. Des sondes à membrane échangeuse d'ions étaient utilisées pour mesurer le taux de fourniture du N biodisponible. Pour la mesure de l'absorption de N des plantes de colza canola étaient cultivées, dans les mêmes conditions environnementales . Indépendamment de leur présen-tation, engrais chimique ou lisier, les apports de N provoquaient une augmentation significative des disponibilités de N assimilable mesurées dans le sol, encore que, sur une période de 84 jours, ces disponibilités étaient 40 % plus basses environ dans le sol amendé au lisier que dans celui fertilisé à l'urée, à dose d'apport équivalente de N total, en raison de la minéralisation incomplète du N organique du lisier. Cependant, le taux d'absorption de N par les plantes était la même dans les deux sols, ce que nous avons expliqué par la présence d'autres nutriments dans le lisier qui auraient eu un effet stimulant sur la croissance racinaire et sur l'absorption de N. De fortes proportions de N ammonical étaient mesurées dans le sol peu après l'épandage, surtout aux fortes doses des deux fertilisants. En revanche, le N minéral sous forme ammonium diminuait rapidement en fonction du temps, si bien que le N nitrique devenait progressivement la principale forme de N minéral disponible. Dans l'ensemble, on relevait une bonne corrélation (r = 0,79-0.96) entre l'absorption de N par les plantes et le taux de fourniture de l'azote assimilable dans le sol, mesuré par la membrane échangeuse d'ions.
