If we now assume the total yield (in the air-dry state) of the pots D in 

 each case of soil respectively to be= lOO, we obtain the following ratio : 



The manurial effect of lime-nitrogen, was in this case, with a small 

 dose of nitrogen, far smaller than that of ammonium sulphate. This 

 difference of the manurial effects between lime-nitrogen and ammonium 

 sulphate was further much larger in the case of sandy soil than in 

 the case of loamy soil. In the case of loamy soil, if we assume the 

 comparative yield from the group B (130) to be =100, and compare the 

 respective yield from the group C (104), we obtain the following ratio : 



Ammonium sulphate. 

 100 



Lime-nitrogen. 

 80 



The comparative yields in the case of sandy soil would be : 



Ammonium sulphate. 

 100 



Lime-nitrogen.
