Excerpt from The Journal of the Royal Agricultural Society of England, 1882, Vol. 18 All the manures, except the dung, are sown broad-cast; during sowing two screens are carried along the boundaries of the plots to prevent the manure being carried beyond its proper limits. The autumn manures are ploughed or harrowed in as soon as possible after sowing, the wheat being drilled afterwards. The spring manures are tap-dressed. The farmyard-manure, the superphosphate, and the sulphates of potassium, sodium, and magnesium, have always been applied in the autumn. During the first six seasons in which the drainage-waters were collected the ammonium-salts were applied on all the plots in the autumn, and had been uniformly so applied for many years previously. Since 187 2 - 3 the ammonium-salts have been applied on Plot 15 at a different time from the other plots. In the five seasons, 1872-3 to 1876 - 7, Plot 15 received its ammonia in the spring, the other plots in the autumn. Since this time the order has been reversed, Plot 15 receiving ammonium-salts in the autumn, and all the remaining plots in the spring. The nitrate of sodium has always been applied in the spring.
