plat (expressed on acre basis), which will enable any one to use

 experimentation have been assumed for the materials used : 



14 per cent Acid Phosphate $14.00 per ton. 



13 per cent Dried Blood 60.00 per ton. 



20 per cent Manure Salt 20.00 per ton. 



Eock Lime 10.00 per ton. 



The arrangements of the plats and the scheme of fertilizer appli- 

 cation is shown by the following: 



Normal Fertilizer Apj)lication, 300 pounds to acre of mixture 

 containing — 



Phosphoric Acid 8 per cent. 



Potash 4 per cent. 



Nitrogen 1 per cent. 



In this Normal Application — 



P equals 24 pounds phosphoric acid, equals 171.4 pounds 



14 per cent acid phosphate ; 

 K equals 12 pounds potash, equals 60 pounds 20 per cent 



manure salt; 

 N equals 3 pounds nitrogen, equals 23 pounds 13 per cent
