INSPECTION OF COMMERCIAL FERTILIZERS 5 



There were 879 less tons of plant food sold in the state than during 1938, of 

 which 333 tons were nitrogen, 305 tons available phosphoric acid, and 241 tons 



potash. 



There were 12,890 tons of plant food sold, of which 27 per cent was nitrogen, 

 43 per cent available phosphoric acid, and 30 per cent potash. Mixed fertilizers 

 furnished 67.6 per cent of the plant food, chemicals and unmixed materials 31.6 

 per cent, and pulverized manures 0.8 per cent. 



The three plant food elements were furnished in the following proportions 

 by the mixed fertilizers and the unmixed materials, including the pulverized 

 manures: nitrogen, 61 per cent from mixed and 39 per cent from unmixed; phos- 

 phoric acid, 64 per cent from mixed and 36 per cent from unmixed; potash, 79 

 per cent from mixed and 21 per cent from unmixed. 



The tonnage tables present figures for one year, July 1, 1938, to July 1, 1939, 

 for both mixed fertilizers and unmixed fertilizer materials. In case of the mixed 

 fertilizers, the grade represents the plant food guarantee and is expressed in the 

 order of nitrogen, available phosphoric acid, potash.
