9. EXPEREVIENTS WITH PERMANENT GrASS LaNDS 



(Meadows). 



The meadows under consideration comprise an area of 

 about 9.6 acres. The entire field up to 1886 consisted of old, 

 worn-out grass lands, overrun with a worthless growth on its 

 more elevated portion and covered w^ith weeds and sedges in 

 its lower portion. The improvement of the land by under- 

 draining was commenced in 1886 and continued during the 

 succeeding years. For details of the work see ninth and 

 tenth annual reports (1891-92). 



In the spriitg of 1893 a change was made in the mode of 

 manuring of the grass plats. It was decided to study the 

 effect of a rotation of the three kinds of manures previoushj 

 applied upon the fields. The area was divided into three 

 plats, Plat 1 (3.97 acres) being the area heretofore covered 

 by plats 1 and 2; Plat 2 (2.59 acres) and Plat 3 (3 acres) 

 correspond to plats 3 and 4 of previous years. The system 

 of manuring adopted was as follows : — 



Plat 1. — Wood ashes, 1 ton to the acre. 

 Plat 2. — Barn-yard manure, 8 tons per acre. 

 Plat 3. — Six hundred pounds fine-ground bone and 200 

 pounds muriate of potash per acre. 



1894. — The above arrangement of plats was continued 

 during the present season, and the fertilizers were applied in 

 the same proportion to the same plats.
