FERTILIZER EXPERIMENTS. 



Prof. Walter Balentine. 



EFFECT OF DIFFERENT FORMS AND MIXTURES 

 OF FERTILIZERS. 



For the past six years the Station has been engaged continu- 

 ously on the same land, with experiments, having for their 

 object (1) The comparative effect of different forms of phosphoric 

 acid in manuring crops ; (2) A comparison between commercial 

 fertilizers and stable manure in crop production ; (3) The effect 

 of a partial and complete fertilizer ; (4) A comparison of the 

 effect of different quantities of fertilizers. 



The results of this work have been published from time to time 

 in the Station Reports. Each year adds a little to the interest 

 and value of the data obtained and the writer ventures to give, in 

 connection with the report of the experiments of this year a 

 review of those of preceding years. 



The soil, or the field on which these experiments were carried 

 out, was in condition to produce a fair crop of hay or grain, 

 when the work was commenced. Thirty-six one-twentieth acre 

 plots were laid off and numbered as indicated in the accom- 

 panying diagram of Experiment Field, No. 1.
