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, 12 lbs. 



Land plaster, 10 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. 



The frequency with which correspondents 

 What not to do. inquire as to the suitability of wood ashes, coal 

 ashes or lime for preserving poultry manures 

 leads me to caution against mixing with these materials. All of 

 them are likely to increase the loss of nitrogen. Wood ashes may 

 be used as a fertilizer in connection with poultry manure, but if so 

 used should be applied by themselves, preferably before applying 

 the poultry manure. 



The fact should be kept in mind when plan- 

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

 try manure. constituents are quickly available. It should 



be remembered, moreover, that the material is 

 naturally so strong that in close contact with either seeds, foliage, or 

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

 mixture as has just been recommended v/ould 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^ to 2^) tons per acre will be 

 the usual range in quantity. It should be remembered that kainit, 

 acid phosphate and land plaster are in themselves fertilizers, and 

 that in mixtures with poultry manures their usual fertilizer action is 

 not at all diminished.
