The writer recommends fine, very dry earth in moderate quantities 

 on the dropping boards and daily removal. To each loo pounds of 

 fresh droppings, add a mixture made up as follows : 

 Kainit, 15 lbs. 



Acid Phosphate, 20 lbs. 



Sprinkle this in proper proportion over each lot of fresh material as 

 it is added to the accumulating stock, and mix before use. 



Such a mixture will give a combination of fertilizer elements in 

 proportions well suited for most crops. 



Do not mix wood ashes or lime with poultry 



What not to do. manure as both of them are strongly alkaline 

 and will release the ammonia which causes a 

 greater loss than if the poultry manure were left in its natural state. 

 Coal ashes if practically free from wood ashes, may be used in place 

 of dry earth as an absorbent : but the mixture should be supplemented 

 with kainit and acid phosphate. 



The fact should be kept in mind when planning 



The use of poul- for the use of poultry manure, that its constitu-

 membered, moreover, that the material is nat- 

 urally so strong that in close contact with either seeds, foliage, or de- 

 licate rootlets in large quantities, it will burn and injure. Such a 

 mixture as has just been recommended would usually best be used 

 by spreading either broadcast or very widely in the hill or drill. It 

 should give excellent results for mowings, lawns and in the garden 



If to be used for potatoes, the writer would prefer using 4 pounds 

 of high grade sulfate of potash in place of the 15 pounds of kainit. 



The quantity of poultry manure applied must naturally be varied 

 with soils and crops, but it should be remembered that such manures 

 well preserved, or such mixtures of poultry manures and chemicals 

 as have been suggested are much stronger and richer than ordinary 

 manures and should be used in smaller quantities. From about one 

 and one-half to two and one-half (i V2 to 23^) tons per acre will be 

 the usual range in quantity. When poultry manure is used without 

 potash salts or acid phosphate it is best applied as a top-dressing, be- 

 cause it is richest in available nitrogen. If it is to be used for garden 

 or field crops, it should always be balanced by the use of kainit, sul- 

 fate or muriate of potash, and acid phosphate.
