“…The pattern of seasonal changes in the contents of NH 4 + f in arable soils is well-known (Kowalenko and Cameron 1976;Sowden 1976;Kowalenko and Ross 1980;Li et al 1990a, b;Drury and Beauchamp 1991;Green et al 1994). Mengel and Scherer (1981), investigating the dynamics of this N fraction in a Fluvisol during the growing season, found that the content of NH 4 + f declined in the top 60 cm from February to May (Fig.…”

“…For example, Nõmmik (1957) has observed fixation of 16-83% in the 0-20 cm layer of soils added with 140 mg NH 4 -N kg − 1 (1 meq NH 4 -N 100 g − 1 ) under laboratory conditions. At higher concentrations of added ammonium, Sowden (1976) measured 38-48% fixation after adding 250 mg NH 4 -N kg −1 , while Doram and Evans (1983) measured 5-29% in six soils after 500 mg NH 4 -N kg −1 were added.…”

“…Fixation is fast and occurs within the first few hours after fertiliser application (e.g., Kowalenko, 1978;Sowden, 1976). On the other hand, its release, which normally concerns only a fraction of the fixed ammonium, is slower and longer-lasting, taking up to several weeks (Osborne, 1976a;Smith et al, 1994;Steffens and Sparks, 1997).…”

“…The decline in NH 4 -N was accompanied by an increase in total NO 3 -N (resin NO 3 -N'soil NO 3 -N), which indicates nitrification of NH 4 -N to NO 3 -N. Sowden (1976) reported the nitrification of applied NH 4 -N as manure or as (NH 4 ) 2 SO 4 , within 3 wk of application.…”

Ige, D. V., Sayem, S. M. and Akinremi, O. O. 2015. Nitrogen mineralization in beef-and pig-manure-amended soils measured using anion resin method. Can. J. Soil Sci. 95: 305Á319. A major challenge facing the widespread use of manure is the uncertainty about its fertilizer equivalence. This study was carried out to determine the fertilizer equivalence of locally available manures in two soils in Manitoba. A randomized complete block design was adopted with six treatments [nitrogen fertilizer, a liquid swine manure (LSM), three solid beef manures (SBM) and a control] and four replicates. Each treatment was applied to a cylindrical soil column installed at the site at the rate of 100 kg ha(1 of ''available N'', and leached NO 3 -N was captured by resin bags at the bottom of the cylinder. The soils and resin bags removed from the cylinders were sampled at 0, 1, 2, 4, 6, 8, 10, 14, and 18 wk following treatment application. Ammonium nitrogen in the amendments was nitrified within the first 2 to 3 wk with significant build-up of NO 3 -N in the soil above the control (PB0.05). The greatest available N was in the fertilizer treatment, followed by the LSM and the smallest was in the SBM. The available N in the three SBM was statistically similar (P0.05). Approximately 50% of the inorganic N in LSM was available during the growing season, while 68 to 100% of SBM inorganic N was available. Between 4 and 25% of the organic N in the three SBM was mineralized during the growing season. High soil moisture hindered N mineralization and enhanced N loss in the clay soil. LSM has the greatest fertilizer equivalence, with a mean of 65 to 68%, of the four manure types used. The fertilizer equivalence of the three SBM ranged between 42 and 59% and was influenced by the manure C:N ratio and the soil environmental conditions. Our study suggests the need to revise the assumptions regarding manure N availability by considering soil environmental factors in the estimation of available N. L'azote ammoniacal des amendements se nitrifie au cours des deux ou trois premie`res semaines et on observe une importante accumulation de N-NO 3 dans le sol au-dessus du traitement te´moin (P B0,05). La plus grande quantite´de N disponible a e´te´releve´e avec l'usage d'engrais, puis de lisier de porc, la plus faible de´coulant de l'application du fumier de bovins. La quantite´de N disponible dans les trois types de fumier de bovins e´tait statistiquement similaire (P 0,05). Environ 50 % du N inorganique pre´sent dans le lisier de porc peuvent eˆtre utilise´s durant la pe´riode ve´ge´tative, contre 68 a`100 % de celui pre´sent dans le fumier de bovins. Quatre a`25 % du N organique pre´sent dans les trois fumiers de bovins sont mine´ralise´s pendant la pe´riode de croissance. Une forte teneur en eau dans le sol nuit a`la mine´ralisation du N et favorise la perte de N dans le sol argileux. Le lisier de porc se rapproche le plus des engrais, avec une e´quivalence moyenne de 65 a`68 % pour les quatre types de fumier teste´s. L'e´quivalence des trois types de ...
