of potash (=:25 to 26 lbs. potassium oxide), and 114 lbs. dissolved 



bone-black (= 16 to 17 lbs. phosphoric acid). 

 54 lbs. muriate of potash (=25 to 26 lbs. potassium oxide), and 114 



lbs. dissolved bone-black (=16 to 17 lbs. phosphoric acid). 

 43 lbs. dried blood (=4 to 5 lbs. nitrogen), 97 lbs. sulphate of potash- 

 magnesia (=25 to 26 lbs. potassium oxide), and 114 lbs. dissolved 



bone-black (= 16 to 17 lbs. phosphoric acid). 



An early maturing variety of white soja bean was the 

 crop employed for the experiment. The field was ploughed 

 April 18, the barn-yard manure having been previously 

 applied to Plat 0, and a quantity of lime to Plat 8.* Plats 

 1-10 received their fertilizer mixtures applied broadcast on 

 May 10. After proper preparation of the soil the soja beans 

 were planted on May 12 in drills two and one-half feet 

 apart, six pounds of seed being used per plat. The plants 

 appeared above ground May 21. June 5 the field was culti- 

 vated and hoed, and also on the 16th and 25th and July 12. 



* This plat had suffered for j^ears, as noted in previous reports, from a serious 

 attack of parasitic growth affecting the yield of the crop, and tlie lime was added to 

 correct the condition of the soil and prevent, if possible, the return of the failure. 

 The purpose for which it was applied was evidently %erved, for the yield of the 

 crop was very satisfactory.
