Report of the Director for the Year igoi. 



The work of the Storrs Station during the year igoi has 

 been largely in continuation of that of previous years. This 

 is in accordance with the policy of the Station since its estab- 

 lishment, namely; to concentrate its energies upon a few im- 

 portant lines of inquiry and to continue on these from year to 

 year as long as circumstances warrant. The principal inquiries 

 now in progress at the Station have to do with the nutrition of 

 plants, domestic animals, and man, and the bacteriology of the 

 dairy. These have included experiments on the effects of fer- 

 tilizers upon the growth and composition of plants, studies of 

 the rations fed to milch cows, studies of bacteria, especially 

 those concerned in normal cream ripening, and investigations 

 on the food and nutrition of man. Some account of the ob- 

 jects, methods and results of various inquiries in these lines 

 are given by different members of the Station staff in this 

 Report. Not all the work done during the year is described 

 in the present volume, since in some cases the results are not 

 5'et ripe for publication; on the other hand, some of the articles 

 include the results of the work of more than a year. 



FIELD AND POT EXPERIMENTS WITH FERTILIZERS. 



The experiments on the effects of fertilizers upon the growth 

 and the composition of plants were carried on in igoi as in 

 previous years at Storrs, under the direction of Prof. Phelps. 

 These include soil tests and soil improvement experiments on 

 field plots, and special nitrogen experiments both on field plots 

 and in pots. Accounts of the experiments of the past year 

 are given by Prof. Phelps in this Report. 



Soil tests. — The experiment known as soil test has been con- 

 tinued at Storrs for twelve years upon the same field. The 

 field is divided into parallel plots of equal size, on which fertil- 

 izers containing nitrogen, phosphoric acid and potash are ap- 

 plied singly and in different combinations, and corn, potatoes,
