the soil and to study the economy of the different methods. 
employed for this purpose. The arrangement of the plots. 
and the method of fertilizing each is shown in the following 
diagram. 
Diagram illustrating arrangement and method of fertilizing plots 
in experiment on soul improvement. 
The narrow strips at the sides and ends of the plots are without fertilizer. 
PLor K. ‘‘Complete” fertilizer, 1200 lbs. per acre. 

Prot L. Stable manure, 12 tons per acre. 
PLor M. No fertilizer, but clover or other legume for green 
manuring. 
PLOT N. Mineral fertilizers, 700 Ibs. acre, and rye for 

manuring. 

Prot P. Mineral fertilizers, 700 lbs. per acre, and clover for 
green manuring. 
The plots contained one-eighth acre each, and are separated 
by narrow strips 3.3 feet wide. These strips between the plots. 
are planted, as well asa similar strip on the outside of the field, 
the same as the plots, but no fertilizers are used on them. The 
crop from these strips is harvested before that on the plots, and 
the yields obtained on them are not included in the experiment. 
The following rotation has been planned: corn, potatoes, oats. 
and peas for fodder, and soy beans. On plots K and L, it has. 
been planned to use approximately the same value of plant 
food, estimating the fertilizer by the usual system of valuation 
adopted by the New England Experiment Stations and esti- 
mating the manure at $3 per cord. Plot K is supplied with a 
liberal quantity (1200 pounds per acre) of a complete fertilizer, 
the ingredients used and rates per acre of each to be as follows: 
nitrate of soda, 200 pounds; sulphate of ammonia, 100 pounds; 
tankage, 200 pounds; muriate of potash, 200 pounds; and South 
Carolina acid phosphate, 500 pounds. Plot L is supplied with
