Nitrogenous Fertilizing and 

 Net Profit. 



Resume of a Lecture by Dr. Paul Wagner. 



"It has been said by an eminent experimenter and farm- 

 er that 'Water and Nitrogen govern the yield and the net 

 profit.' Is it correct? May it be accepted as a rule that, 

 where there has been a poor crop, deficiency of moisture or 

 hunger for nitrogen, or both, are the principal causes? May 

 it be accepted as a rule that, when a field needs fertilizing, it 

 requires in the first place nitrogen, and only in the second 

 place phosphoric acid and potash, in order to produce maxi- 

 mum yields? The question is an important one, and well 

 worthy of study." 



Experiments with Oats on Different Soils. 



At the Darmstadt Experiment Station last summer 

 were cultures of oats, which presented a clear picture of the 

 manurial requirements of various Hessian soils. Samples 

 had been taken of the field soil of eleven several districts, 

 which had been placed in vegetation pots, variously fertilized, 

 and seeded with oats. 



Methods of Fertilizing. 



The first pot received a complete dressing of potash, 

 phosphoric acid and nitrogen, in sufficient quantity to pro- 

 duce the highest possible yield. 



The second pot received the like dressing, but without 

 phosphoric acid.
