Abstract
An account is given of observations made during the first two years' treatment of grass according to the “New System of Grassland Management,” i.e. periodic dressings of nitrogenous manure followed by rotational grazing.The grazing provided by the nitrogen and no-nitrogen plots in the two years is given, measured in cow-day equivalents.A method of sampling the plots with a view to determining the total weight of herbage produced and its chemical and botanical composition is described.Botanical and chemical results obtained by this method are given and discussed.The percentage of clover on the nitrogen plots is about one-quarter of that on the control plots.The dry matter of the herbage on the nitrogen plots has, on the average, contained 17·7 per cent, crude protein: that on the no-nitrogen plots 15·5 per cent. The average age of the grass when sampled was 35 days.
