RIGHT USE OF LIME IN SOIL IMPROVEMENT 



sour, and there is reason to believe that it is 

 much better to use such quantities without 

 question than to defer liming for a year in 

 the hope that some more definite knowl- 

 edge of a particular field's needs may be 

 secured. 



Small Amounts Per Acre. There is 

 much experience as a basis for the claim 

 that a few hundred pounds of burned lime 

 per acre may have marked results. Fields 

 that indicated an actual lime requirement 

 of a ton of fresh lime per acre have had a 

 test of 500 pounds per acre made in strips, 

 and the clover later on was so superior to 

 that which was struggling to live in the un- 

 treated portion that the light application 

 appeared almost to be adequate. In such 

 land there cannot be full bacterial activity 

 or continuing friendliness to plants unless 

 the need is met fully. A larger application 

 would have paid better. It is the soil rich 

 in lime that can make the best response to 

 tillage and fertilization. 



A Heavy Soil. When burned lime is 

 not high in price, an application of two tons 

 per acre may be more profitable than a 

 smaller one. A heavy soil needs to be 

 richer in lime than a light one for best re-
