“…Environmental soil phosphorus tests that involve water extraction routinely use air-dried soils and only measure inorganic phosphorus (e.g. [73,74]). The results of these tests will clearly vary depending on the moisture status of the soil prior to extraction and on the inclusion (or not) of organic phosphorus.…”

“…Soil P tests often use strong chemical extractants, which may overestimate potential P loss in runoff waters from manure-applied soils, because CaÁP minerals that are insoluble in water are dissolved by the extractant (Sharpley et al 2004). For environmental purposes the distilled water extraction is useful for predicting mobile P fractions because it can accurately estimate the saturation concentration of the P adsorption complex (Atia and Mallarino 2002), and has shown a high correlation (r 2 00.82**) with dissolved P in runoff (Pote et al 1996). The water extraction method is considered to accurately simulate the effect of rainfall and provide the best estimate of P loss potential (Wright et al 2003); however, results from Alberta, Canada, indicate that agronomic-based P tests, like the Modified Kelowna (MK) method, were more useful in detecting build-up, at lower ranges of soil P (Wright et al 2003).…”

Stumborg, C. and Schoenau, J. J. 2008. Evaluating phosphorus loading from repeated manure applications to two Saskatchewan soils. Can. J. Soil Sci. 88: 377Á387. An understanding of the impact of repeated manure additions on soil phosphorus (P) is needed to determine appropriate manure application rates for prairie soils and manure sources. The objective of this study was to assess the loading of manure-derived phosphorus using P budgets and soil P measurement techniques applied to two Saskatchewan soils with known histories of manure application. Liquid hog manure (LHM) and solid cattle manure (SCM) treatments were applied annually over 8 yr to Black Chernozemic soils (Dixon site), and LHM was applied to Dark Brown Chernozemic soils (Plenty site) over 6 yr. Soil samples were collected in the spring of 2003 and 2004 and analyzed for labile P (Modified Kelowna extractable, Olsen extractable, water extractable, and Plant Root Simulator exchange resin methods) and total P. The P budgets were in good agreement with the observed patterns in labile soil P at the two sites. The annual application of LHM (37 000 L ha Á1 yr Á1) at agronomic nitrogen (N) rates with no additional P fertilizer (Dixon only) did not significantly elevate soil labile P compared with the unfertilized controls at both Dixon and Plenty. The annual application of SCM (7.6 Mg ha Á1 yr Á1 ) at agronomic N rates did not significantly elevate soil labile P compared with the unfertilized control at Dixon; whereas application of SCM at higher rates (15.2 Mg ha Á1 yr Á1and 30.4 Mg ha Á1 yr Á1 ) showed some elevation in labile soil P. Measures of labile P were sensitive to P surpluses or deficits predicted by P balances, and all methods of measuring labile soil P were strongly correlated with one another at both sites (r ]0.803 at P50.01).Key words: Manure, cattle manure, nitrogen, phosphorus, soil test phosphorus Stumborg, C. et Schoenau, J.

Il faut comprendre l'impact de l'addition re´pe´te´e de fumier sur la concentration de phosphore (P) dans le sol si l'on veut e´tablir les taux d'application approprie´s pour cet amendement sur les sols des prairies en fonction des sources de fumier.

Le bilan du P concorde bien avec les tendances observe´es au niveau de la concentration de P labile aux deux sites.
