 which is the application of acid fertilisers. Sul- 

 phate of ammonia causes a loss of carbonate of 

 lime, which must be replaced, otherwise the land 

 becomes acid in course of time. 



There seems to be good reason to believe, 

 from the careful experiments which are in pro- 

 gress, that the two new nitrogenous 

 from the fertilisers obtained from the air, and 

 Atmosphere, known as Nitrolim and Nitrate of 

 Lime, will prove to be valuable 

 sources of nitrogen. It is to be hoped that, when 

 they are manufactured in sufficient quantities, 

 and further experiments have demonstrated 

 their value, their production will 

 steady the cost of nitrogen, which 

 has always been liable to sudden 

 and considerable fluctuations, nitrate of soda 

 especially.

 and distinct advantages ; it adds humus and is 

 held by the soil and assimilated by the plants as 

 required ; there is no danger of its being washed 

 away in the drainage water, which is a matter of
