Simulated swards of reed canary grass ( Phalaris arundinacea L ) and ryegrass received applications of separated cow slurry liquor in winter, at rates up to the equivalent of 500 m 3 ha −1 . Subsequent measurement of oxidized nitrogen in the soil under the different species indicated that lower levels of soluble forms of nitrogen were found under the reed canary grass than were under the ryegrass sward. At the first harvest after liquor application, the dry weight yield of reed canary grass responded positively to increasing applications of slurry liquor, but the ryegrass sward appeared to be damaged by very high rates of application. At later harvests, yields of the two species were similar, but over the season, apparent recovery of the nitrogen applied to the swards was greater in the reed canary grass than in ryegrass, suggesting that this species could be of value in the control of losses of nutrients from livestock wastes.
