Extract

1. Two experiments are described in which nine manurial treatments were applied ranging from no application to an application of 312 lb. N, 135 lb. P2O5 and 168 lb. K2O per acre in one season. Some treatments included one or more massive dressings of nitrogen (104 lb./acre), while others received several light dressings spread over the season. The applications were made at differing periods of the season. In one experiment (Series 3) the treatments were applied to a 1-year Italian ryegrass ley, in the other (Series 4) to an established ryegrass pasture.
