On the Hoos Field the barley was sown on March 21st; it 

 made a poor start, and though it improved in the early spring, the 

 eventual yield was much below the general average and even below 

 that of the previous year. The proportion of offal grain was high 

 and the weight per bushel low. The most noticeable feature was 

 the exceptional increase produced by superphosphate, the plots 

 without phosphoric acid fell to a very low level indeed. This 

 prevails generally in the experiments ; phosphoric acid has its 

 maximum effect in wet and cold seasons. The straw also gave 

 less than its average yield, although it was above the average 

 of recent years. The last two wet seasons have made the barley 

 plots excessively weedy, and they are now much worse than 

 Broadbalk which has been got into a comparatively clean condition. 



The permanent Grass plots in the Park also yielded much 

 smaller crops than usual, and the proportion of the leguminous 

 herbage was considerably below the average. The effect of lime on 

 the half plots was not so marked as usual, though its value was very 

 apparent to the eye on the plots on which the soil has become sour 

 through continual applications of ammonium salts. On the limed por- 

 tions of the plots the peat that had accumulated previously has almost 

 entirely disappeared, and a close sward is beginning to form again. 



The Mangold Field was sown on April 15th to 18th and a good 

 plant was obtained on all the plots, except on those receiving nitrate 

 of soda and sulphate of ammonia. These were resown on May 31st, 

 and owing to the cool showery weather a fair plant was eventually 

 obtained, which did not seem behind the rest at harvest. The yield 

 was above the average, though by no means so good as in the pre- 

 vious year or in 1907. The effect of the usual attack of Uromyces 

 betce on the high nitrogen plots was very marked. 



On Agdell Field the turn for clover and bare fallow came in 

 1910 ; a fair plant of clover showed after the winter, but grew very 

 indifferently in the spring, and gave a poor yield. It was cut on 

 June 21st, and was followed by an altogether exceptional after- 

 growth ; the second crop, cut on September 13th, was larger than 

 the first, indeed nearly ten times as great in the case of the unmanured 

 plot. The total of the two crops, first and second cut, is larger than 

 on any previous occasion. 



On Little Hoos Field wheat was sown, although barley had 

 been taken in the previous year. This was done in order to break 

 the sequence of the rotation, as it was often inconvenient to have 

 the same crops on Agdell and this field in the same year. An even 

 plant was obtained, but the yield was very disappointing; none of the
