or raked in. The first only is soluble and adapted for 

 use in liquid form. 



Generally, organic manures are best applied in the 

 autumn, and it is convenient to distribute them in times 

 of frost, when the ground is hard and therefore not easily 

 disturbed by the wheelbarrow and gardener's boots. 

 Animal manures of the farmyard and stable type may be 

 used at the rate of two barrow loads per square rod. 



Farmyard manure is naturally variable in the pro- 

 portions of its fertilizing constituents. An average sample 

 may be considered as containing: 



12 to 15 pounds of nitrogen 

 10 to 15 " potash 

 7 " phosphoric acid 



20 " lime 



^to the ton of manure 



An excellent general chemical manure is a mixture 

 of superphosphate of lime four pounds, and kainit, two 

 pounds. This should be dug in early in the spring and 

 may be supplemented later, when the plants have 

 started into growth, by applying nitrate of soda, two 

 pounds. The quantity given is for one square rod of 

 surface. 



The following manures for special purposes are recom- 

 mended by a successful market gardener.
