“…Short-term (7 day) anaerobic incubation resulted in N release that was well correlated with that derived from a 30-week aerobic incubation, leached regularly. Soil drying prior to incubation increased N release from both soils as has been previously observed (Westerman et al 1988). Since soil drying had a somewhat different influence on N released anaerobically (Fig.…”

Abstract. Piggery pond sludge (PPS) was applied, as-collected (Wet PPS) and following stockpiling for 12 months (Stockpiled PPS), to a sandy Sodosol and clay Vertosol at sites on the Darling Downs of Queensland. Laboratory measures of N availability were carried out on unamended and PPS-amended soils to investigate their value in estimating supplementary N needs of crops in Australia's northern grains region. Cumulative net N mineralised from the long-term (30 weeks) leached aerobic incubation was described by a first-order single exponential model. The mineralisation rate constant (0.057/week) was not significantly different between Control and PPS treatments or across soil types, when the amounts of initial mineral N applied in PPS treatments were excluded. Potentially mineralisable N (N o ) was significantly increased by the application of Wet PPS, and increased with increasing rate of application. Application of Wet PPS significantly increased the total amount of inorganic N leached compared with the Control treatments. Mineral N applied in Wet PPS contributed as much to the total mineral N status of the soil as did that which mineralised over time from organic N. Rates of CO 2 evolution during 30 weeks of aerobic leached incubation indicated that the Stockpiled PPS was more stabilised (19-28% of applied organic C mineralised) than the Wet PPS (35-58% of applied organic C mineralised), due to higher lignin content in the former. Net nitrate-N produced following 12 weeks of aerobic non-leached incubation was highly correlated with net nitrate-N leached during 12 weeks of aerobic incubation (R 2 = 0.96), although it was <60% of the latter in both sandy and clayey soils. Anaerobically mineralisable N determined by waterlogged incubation of laboratory PPS-amended soil samples increased with increasing application rate of Wet PPS. Anaerobically mineralisable N from field-moist soil was well correlated with net N mineralised during 30 weeks of aerobic leached incubation (R 2 = 0.90 sandy soil; R 2 = 0.93 clay soil). In the clay soil, the amount of mineral N produced from all the laboratory incubations was significantly correlated with field-measured nitrate-N in the soil profile (0-1.5 m depth) after 9 months of weed-free fallow following PPS application. In contrast, only anaerobic mineralisable N was significantly correlated with field nitrate-N in the sandy soil. Anaerobic incubation would, therefore, be suitable as a rapid practical test to estimate potentially mineralisable N following applications of different PPS materials in the field.Additional keywords: piggery manure, nitrogen mineralisation potentials, aerobic mineralisable N, anaerobic mineralisable N, ammonium-N, nitrate-N.

“…The manure treatments were chosen to represent approximately one and two times the maximum acceptable rate of poultry manure application for raspberry (BCMAFF 1992), while the inorganic fertilizer N rate was the recommended value for raspberry production (BCMAFF 1994). The 100M and 55F treatments were expected to supply similar quantities of plant-available N, assuming 50% availability of poultry manure N in the year of application (Castellanos and Pratt 1981;Westerman et al 1988).…”

“…Poultry manure commonly has a total N concentration ranging 20 -80 g N kg -1 on a dry-weight basis, with 72 -88% of the N in organic form (Sims 1987;Bitzer and Sims 1988;Westerman et al 1988). Organic N in poultry manure mineralizes more rapidly than the organic N in other manures and sewage sludge (Pratt et al 1973;Castellanos and Pratt 1981;Sims 1986;Bitzer and Sims 1988).…”

Based on incubation studies, poultry manure N availability is estimated to be about 50% (Castellanos and Pratt 1981;Westerman et al 1988). Most of the N release from poultry manure is expected to occur in the year of application (Pratt et al 1973).…”

K. 2000. Poultry manure effects on soil nitrogen processes and nitrogen accumulation in red raspberry. Can. J. Plant. Sci. 80: 849-860. This study examined the effects of solid poultry layer manure addition on soil N processes and on dry matter and N accumulation in red raspberry (Rubus idaeus L.). In trials conducted in two years, approximately 50% of the 400 kg total N ha -1 applied as manure was recovered as soil inorganic N 1 mo after manure application when manure was incorporated within 4 h of application. Three trials were conducted in two commercial raspberry fields: one with no history of manure use and one other with a history of heavy annual applications of poultry manure. Treatments included 55 kg N ha -1 as NH 4 NO 3 , 100 or 200 kg total N ha -1 as manure, and a control that received no manure or fertilizer N. Soil inorganic N to 60 cm depth was measured throughout the growing season. Berry yield was estimated, and dry matter and N accumulation was determined in floricanes at first berry ripening and in primocanes at the end of the growing season. Few significant effects of N fertilization were measured for any crop yield, growth or N accumulation parameter. This was attributed to the large (> 150 kg N ha -1 ) supply of N to the crop in the unamended soil, primarily from soil N mineralization. Dry matter accumulation in the fruiting clusters was strongly correlated to estimated berry yield, and may provide a simple means for assessing relative yield within experiments. Soil nitrate measured in August after berry harvest may serve as a "report card" to assess N management in the current growing season, to refine fertilizer N management for subsequent growing seasons, and as an index of the risk of nitrate leaching over the following fall and winter in south coastal British Columbia. ). Au cours d'essais de deux ans, quelque 50 % des 400 kg d'azote total par hectare apporté sous forme de fumier était récupéré à l'état minéral un mois après l'épandage lorsque le fumier était incorporé au sol dans les 4 heures suivant l'épandage. Trois essais étaient réalisés dans deux framboisières commerciales, l'une sans antécédents d'utilisation de fumier et l'autre qui avait reçu au cours des années d'abondantes quantités annuelles de fumier de volaille. Les traitements comparés étaient : 55 kg N ha -1 sous forme de NH 4 NO 3 , 100 ou 200 kg N total ha -1 sous forme de fumier de volaille et un témoin sans apport de N organique ou minéral. La teneur en N minéral du sol jusqu'à 60 cm de profondeur était mesurée tout au long de la saison de végétation. Le rendement fruitier était calculé et la teneur en matière sèche et l'accumulation de N dans les tiges de deuxième année étaient mesurés à la maturité des premiers fruits et dans celle de première année à la fin de la saison. L'apport de N n'avait que peu d'effet significatif sur les des paramètres de rendement, de croissance ou d'accumulation de N, ce qui s'explique par l'abondante biodisponibilité de N (>150 kg ha -1 ) dans le sol non engraissé, surtout sous forme ...

“…Castellanos and Pratt (1981) incubated several animal manures in a San Emigdio frne sand and Holtville silty clay and reported more N mineralized in the fine sand for all ty"Pes of manures. After incubating three BLs and two turkey litters on one loam and two loamy sand soils, Westerman et al (1988) noted that more N was mineralized from the loamy sand soils for all litters. Sorensen and Jensen (1995) found increasing net N immobilization with increasing clay concen trations, and in a related study using N from sheep urine, found more N inullobilization in a sandy loam compared to a sandy soil.…”
