National audienceThe kinetics of sewage sludge phosphorus release was studied by a biological short and middle term test : 3 doses of phosphorus were supplied as digested sewage sludge or as monocalcium phosphate in pots filled with sand and planted with ray-grass (Lolium hy6ridum Hausskn. var. « Sabrina »), in a growth chamber. According to the STANFORD & DEMENT method, ray-grass tops were harvested after 7 days of root soil contact ; cultivations were then continued through 17 cuttings until depletion of phosphorus sources, that required nearly 300 days. The relative efficiency of sludge phosphorus was defined as the ratio between slopes of regression straight lines of cumulative phosphorus uptake to phosphorus supply, as sludge on one ha...
