Table VIII. 

 The Lime Requirement of some adjacent Limed and Unlimed Soils. 



In connection with field experiments of this kind at the Woburn 

 Station, Hutchinson and MacLennan have arrived at the following 

 conclusion: "Without necessarily indicating that the controlhng factor 

 in crop production of these (barley) plots is one of physiological resistance 

 to soil acidity, there is stiU a very close agreement between yields and 

 soil reaction. In all cases where the soil is neutral in reaction, high 

 returns are obtained; where the requirement is more than 0-18 %, the 

 crop shows almost if not complete failure.... Some what similar data were 

 obtained with the soils from the permanent wheat plots, although in
