A lime spreader is an economical implement to use in spreading 

 costly material. 



Lime should not be mixed with either fertilizer or manure. 

 It should be worked into the soil separately. 



Haul the lime when there is a slack time and if possible when 

 the roads are good. 



The primary object of lime is to increase the availability of 

 plant food. 



If there is no plant food in the soil, the application of lime 

 will be unavailable. . 



It will correct the acidity of any soil but it cannot promote 

 bacterial activity' without plant food for the feeding of soit 

 organisms. 



The promotion of the growth of legumes is the one result above 

 all others which makes lime one of the most important factors 

 in scientific agriculture. 



Effects on a new leguminous crop will not show its full value 

 until the crop has become thoroughly innoculated. 

 Innoculation may not take place till the second or third year. 

 Lime will neutralize the effects of certain toxic or poisonous 

 substances in the soil which are believed to be caused by con- 

 tinuous raising of one crop (without rotation). 

 Limestone and phosphate rocks are among the most important 

 of the earth's conservations of our natural resources. These 

 rocks were stored away ages ago, and we are now just beginning; 

 to learn their real value.
