1913] Lime ox Soils 61 



The finest grained limes are tlie air-slaked and the hydrated 

 forms. 



TJnground limes and marls should be extremely well decayed. 



The degree of acidity present and the amount of plant food 

 in the soil determine the amount of lime to be used. 



One or two tons per acre applied every two or three years is 

 much better than larger amounts added at longer intervals. 



Lime should be shipped in its most condensed form (quick- 

 lime) and hydrated on the farm where it is used. 



Ground lime should be applied in the summer or fall to be 

 available for the next spring crop. Hydrated lime is put on 

 (do not mix it with phosphates) about a month before seeding. 



The limestones and most of the marls of the Atlantic and 

 Gulf Coastal Plains are desirable for use as ground material. 



In Europe and America nearly all of the experiments con- 

 ducted to test the relative value of ground limestone and the 

 hydrated lime as amendments to soils deficient in lime, have 

 produced results favorable to the lime carbonate.
