34 The Profitable Culture of Vegetables. 



Mixtures of Manures. In mixing manures together great 

 care must be exercised. If the wrong kinds are put together 

 certain chemical reactions will take place and much loss will 

 result. 



The following mixtures may be made with safety : 

 Superphosphates with Sulphate of Ammonia. 

 Bones with Nitrate of Soda or Sulphate of Ammonia. 

 Bones with Basic Slag. 

 Basic Slag with Nitrate of Soda. 

 Fish Guano with any Mineral Fertilizer. 



, Phosphatic Guanos with Nitrate of Soda or Sulphate of Ammonia. 



Kainit with Basic Slag. 



The following mixtures should not be made : 



Farmyard Manure with Lime. 



Guano with Lime. 



Guano with Basic Slag. 



Nitrate of Soda with Superphosphates. 



Sulphate of Ammonia with Basic Slag. 



Kainit with Nitrate of Soda. 



NOTES ON THE USING OF FERTILIZERS. 



Whenever artificial fertilizers are used an ample supply of 

 moisture and a well-pulverized soil are of the utmost impor- 

 tance. Moisture by its dissolving action renders the manure 

 soluble and brings it into a condition to be easily assimilated 

 by the roots of plants. 



No fertilizer can be effective unless it reaches the roots of 

 the plants, therefore pains must be taken to distribute it 

 evenly over the whole ground. To do this properly with small 

 quantities of a highly-concentrated material is very difficult 

 unless fine dry soil, sand, ashes, or something similar is added 

 to increase the bulk. 



Fertilizers which are readily soluble can be scattered over 

 the surface and the first rains will distribute them uniformly 

 through the soil. Fertilizers slowly soluble should be turned 

 under at once, so that the soil constituents can immediately 

 begin to act upon them. 



A quick-growing plant needs a fertilizer which is more 

 readily-available than does one which occupies the ground for 

 a long period.
