View larger version (17K): [in a new window]   Fig. 1. Dates of bedding addition (empty symbols) to feedlot pens in relation to rainfall simulations (half-filled symbols) in 1998 and 1999. Pens for bedding addition and rainfall simulations were the same in 1998 (a, b). Pens for bedding addition in 1999 were different than pens for rainfall simulations (c). Mean weight of bedding for three pens in 1999 was used. Weights of bedding applied to all pens in 1999 were similar.

Bedding x location effects on mean values (±1 SE) of dissolved reactive phosphorus, DRP (a), total P (b), and NH4–N (c) in 1998, and total Kjeldahl nitrogen (d) in runoff in 1999 from a feedlot in southern Alberta. Mean values with the same lowercase letter are not significantly (P > 0.05) different. Labels on the x axis are ST (straw), WD (wood), BP (bedding pack), and PF (pen floor).

Bedding x location effects on mean (±1 SE) mass loads of dissolved reactive phosphorus, DRP (a), total P (b), and NH4–N (c) in runoff from a feedlot in southern Alberta in 1998. Mean values with the same lowercase letter are not significantly (P > 0.05) different. Labels on the x axis are ST (straw), WD (wood chips), BP (bedding pack), and PF (pen floor).
