Investigations into the Intensive System of Grassland Management. By the Agricultural Research Staff of Imperial Chemical Industries, Limited. XI. The Effect of Nitrogen on the Yield, Composition and Digestibility of Grassland Herbage. (With Five Text-figures.)

Abstract

An experiment was carried out in 1929 and 1930 to obtain a measure of the effects of nitrogenous fertilisers used in combination with rotational grazing, on grass adequately supplied with phosphates, potash and calcium. A comparison of the two years has shown that the magnitude of these effects is governed by climatic conditions, and in the absence of a sufficient supply of moisture the increase in the quantity of herbage produced is reduced.
