CHAPTER III 

 APPLYING LIME 



Forms of Lime. There is unnecessary con- 

 fusion in the mind of the public regarding the forms 

 of lime that should be used. If amounts greatly 

 in excess of needs were being applied, the form 

 would be a matter of concern. There would 

 arise the question of soil injury that might re- 

 sult from the use of the lime in caustic form. 

 Again, if pulverized limestone were used, a very 

 heavy application would bring up the question of 

 coarseness in order that waste by leaching might 

 be escaped. Most farms needing lime do not have 

 cheap supplies, and the consideration is to secure 

 soil alkalinity at a cost that will not be excessive. 

 Freight rates and the cost of hauling to the fields, 

 added to first cost of the lime, limit applications 

 on most farms to the necessities of a single crop- 

 rotation which includes clover, or, at the most, to 

 two crop-rotations. Under these circumstances
