262 7 he Wohurn Field Experiments, 1907. 
1907. 
The manurial applications having last gone on in 1904, 
basic slag and lime were respectively applied at the end of 
October, 1906, farmyard manure on December 10, 1906, 
superphosphate and sulphate of potash on March 12, 1907, and 
nitrate of potash on April 9, 1907. The grass grew well and was 
cut for hay June 25 to July 19. Owing to the very uncertain 
weather, care was taken only to cut as much of the field as 
could be dealt with at the time, and in this way the whole crop 
was got in in very good condition. The weights of hay on the 
experimental plots are given in Table XIII.

It will be seen that these plots came out very well, the 
lowest yield being given on the unmanured plot (4). Lime 
alone (plot 5) did nothing in the way of producing a heavier 
crop, but the grass was of distinctly finer quality than on plots 
4 and 6. Farmyard manure (plot 6), as usual, gave a large crop 
but of coarse character. The plots manured with basic slag or 
superphosphate, along with potash salts, were the best, and 
contained the most clover. The actually highest yield was 
that of plot 3 — basic slag and sulphate of potash. 
As regards the botanical composition of the herbage, it will 
be noticed that plot 2 again assumes the high place it had in 
1903 as containing the greatest amount of leguminous plants ; 
plot 3, as before, is next best in this respect, while the 
unmanured plot shows the lowest percentage of leguminosae.

In 1905 the plots were grazed ; they were chain-harrowed 
and rolled in the spring of 1906 and cut for hay on June 30.
