Liming 



truth of his statement that " Hme, when hiid on in large 

 quantities, has in this country a wonderful effect." 



General Conclusions. 



(1) Liming as a general farm practice must receive more 

 attention if soil fertility is to be raised and food production 

 increased. 



(2) Great losses must be taking place in connection with the 

 pasture land of the country because soils are deficient in lime 

 when grass and clover seeds are sown. 



(3) In view of both the increased cost of fuel and the improve- 

 ments which have been effected in the construction of pulverizers 

 and crushers, ground limestone may under many circumstances 

 be advantageously taken as a substitute for burned lime. 



(4) A demand for ground limestone may lead to the opening 

 up of disused quarries outside coal areas, and may thus establish 

 new centres of distribution. 



(5) There appear to be various reasons why expenditure on 

 ground limestone has often been unremunerative in the past, 

 viz. : — 



(a) Coarseness of grinding. 



(h) More impure limestone used for its manufacture than 

 was the case for the production of burned lime. 



(c) The smallness of the dressings which have often been 



applied to soils which needed fairlv heavy liming. 



(d) The exorbitant prices which have on occasions been 

 charged for it.
