SUCCESSFUL FARMING 



affected by the failure of clover. On experimental plats where ammonium 

 sulphate has been used, the acidity has become so marked that all of the 

 crops in the rotation are directly affected. The degree of tolerance of 

 these crops is in the following order: oats, wheat, corn and red clover; the 

 last being the least tolerant of soil acidity. 



At the Rhode Island Experiment Station, Wheeler has made extensive 

 tests of the tolerance of plants to soil acidity, and the relative benefits of 

 applying lime. The following table shows the plants falling into three 

 classes: first, those benefited by lime; second, those but little benefited 

 by lime; third, plants usually or frequently injured by lime.
