The manures were last applied in 1903. The weights of hay 
are given in Table XIV.

Superphosphate and kainit gave the largest crop, and then 
basic slag and kainit, but the increases over the unmanured 
plot were but small. Lime used alone gave no benefit. 
1907. 
Lime (Buxton lime) — 2 tons per acre — was applied to plot 1 
on October 29, 1906, and basic slag to plot 4 on November 3, 
1906 ; the dressings of superphosphate and sulphate of potash 
went on to plots 3 and 4 on March 22, 1907. The plots were 
cut for hay June 21-28, and the weights per acre are given 
in Table XV.

Here, as in Broad Mead, the unmanured plot (2) gave the 
lowest yield. Lime (plot 1) effected a slight improvement, 
especially in the quality of the herbage. Basic slag and 
sulphate of potash (plot 4) were disappointing in their result, 
and decidedly the highest yield was given with superphosphate 
and sulphate of potash (plot 3). 
In addition to the foregoing, field experiments on grass land 
(Broad Mead) were carried out in 1907 with different kinds of 
sewage sludge, on behalf of the Royal Commission on Sewage 
Disposal. These form the subject of a separate report to the 
Board of Agriculture.
