asked the Minister of Agriculture to what extent, in view of the experience in parts of the U.S.A., researches are conducted in this country into the effects on soil fertility by the continued use of inorganic manure.

The continuous use of inorganic manures has been the subject of numerous experiments in this country, notably at the Rothamsted Experimental Station where heavy annual dressings of fertilisers alone have been applied for over a 100 years, and where high crop yields have been maintained and the soils are for the most part still in excellent condition. I am sending my hon. Friend a reprint of a paper dealing with the subject.
