4 FERTILISERS AS AN AID TO 



fuse farmers, and have caused a widespread 

 distrust of all fertilisers, a state of affairs which 

 greater knowledge of the facts as demonstrated 

 by scientific and reliable experiments can 

 remedy with benefit to all concerned. 



A large number of such experiments have 

 been conducted during late years all over the 

 United Kingdom under the careful supervision 

 of well-known agricultural authorities, and these 

 have confirmed, in a most conclusive manner, 

 earlier trials made both here and abroad, the 

 small variations being due principally to differ- 

 ences in soil, climate, and situation. 

 Large profit* jh ese demonstrations have proved 



FwruuMra! ^^ a ^ cr P s can ^ e vastly increased by 



the judicious use of fertilisers, and 



that this increase means a very large profit on 



the outlay. In fact, nothing pays the farmer so 



well as his manure bill ! 



All plants depend on certain substances for 

 their proper grov/th. Many of these are nearly 

 always present in the soil. There are others, 

 however, which are always more or less deficient 

 in an available form, and these plant 

 foods, as they are called, are abso- 

 lutely indispensable for perfect 

 growth. These are known as Phosphoric Acid 

 (which is the active principle in Phosphates), 

 Nitrogen, Potash, and sometimes Lime. These 

 must all be present in sufficient quantities 

 for nil crops. Should one or more be deficient, 

 the amount of the crop will be limited by the 

 essential element of plant food which is present
