The assimilation of phosphoric acid by grapes, E. Zacharewicz I Prog. Agr. 

 it ]'il. ( Ed. VEst), 25 i 1904), No. 43, pp. $59-462). — Experiments were made to deter- 

 mine what influence the use of superphosphates would have on the phosphoric acid 

 content of the fruit and wine. 



Physical and chemical analyses are given of the soils on which the experiments 

 were carried out and the usual experimental details recorded. The amount of super- 

 phosphate used on the different plats varied from none on the control plat to 45, 90, 

 and 135 kg., respectively, on the other ."» plats. The analyses of wines made from 

 the grapes grown on the different plats showed that there was 10 times as much 

 phosphoric acid in the wine from the plat which had been fertilized with 135 l<L r . of 

 superphosphate as from the control plat. 



The conclusion is drawn that phosphoric acid may he accumulated in part in fruit 

 and contribute its beneficial influence to the wine made from it.
