The Honorable Commissioner of Agriculture, Albany : 



Sir. — This bulletin is the record of extension experiment work 

 done under the auspices of the State appropriation, in fertilizing 

 strawberry fields. The work was undertaken upon request of the 

 Oswego berry growers, wliose commercial interests in strawberries 

 are large. The experiments were begun in 1897 and are still con- 

 tinuing. Of the various tests that have been made, 64 are reported 

 herewith. The object of the experiments is to determine what 

 fertilizers it pays to use on strawberry fields under general com- 

 mercial conditions. It is not to be expected that this question can 

 ever be finally answered, for each field is a law unto itself ; yet the 

 experiments show that in the Oswego district and under the good 

 culture given by the best berry growers, heavy applications of 

 nitrogen are not required and that mineral fertilizers conduce to 

 the solidity and quality of the fruit as well as to productiveness. 



On request of leading berry growers, a short historical sketch is 

 also given of the Oswego strawberry business.
