FIELD EXPERIMENTS WITH FERTILIZERS. 
BY ECS. Pile aoe 

The field experiments conducted by the Station during the 
year 1896 have been carried out mainly on the Station land 
at Storrs. They have been almost wholly a continuation of 
experiments which were designed to run through a period of 
years, and of which accounts have been given in previous 
reports. The field work has been in four lines:— 
I. Special nitrogen experiments on corn, legumes, and 
grasses; for the purpose of studying the effect of different 
quantities of nitrogen on the yield and composition of the 
crop. 
2. A rotation soil test on the Station land for the purpose 
of studying the deficiencies of the soil and the needs of differ- 
ent crops for the different fertilizer ingredients. 
3. Experiments on the improvement of light ‘‘ plain land’’ 
soils by green manuring with legumes. These experiments 
will have to be continued at least another year before results 
of material value can be obtained. 
4. ‘The growing of different kinds of forage crops for use 
in soiling experiments with milch cows, and for digestion expe- 
riments with sheep. The main value of these experiments 
is ina study of the digestibility of soiling crops in different 
stages of growth. (See account of digestion experiments with 
sheep, beyond. ) ; 
SPECIAL NITROGEN EXPERIMENTS. 
In the fall of 1894 the plots on the field at the Station that 
had been used for several years for special nitrogen experi- 
ments on grasses, were subdivided into a number of smaller 
plots of one-fiftieth of an acre each, and experiments were 
planned for the purpose of comparing the effects of fertilizers 
on the yield and composition of two varieties of corn, and 
several varieties of legumes. Each of the smaller plots was to 
have the same treatment as regards kinds and proportions of
