able for the cultivation of arable than grass lands, for the plow 

 mixes it with the mass of the soil. It pays better, especially on 

 sloping lands, to apply a little manure frequently than much 

 manure at greater intervals." Some grasses draw much more 

 potash and phosphoric acid than others. Here are two mixtures 

 in which the requirments of potash and phosphoric acid greatly 

 differ. The tables are from Mr. Julie :

It will be seen that the average of the second mixture is only 

 about half as exhaustive to the soil as the first in producing the 

 same amount of hay. 



In 1858 Baron Lawes said: ''The best artificial manures for 

 grass land are Peruvian guano, and nitrate of soda and sulphate 

 of ammonia." In 1875 he wrote: "I am disposed to think a 

 dressing of dung once in five years and 2 cwt. of nitrate of soda 

 the other four is about as good an application as can be used. 

 Peruvian guano, when alone, may be used at the rate of 150 or
