One ton of this mixture will supply about: 



Nitroj^cn, 16 pounds, 



Phosi)horic acid, 70 pounds, 



Potash, 30 pounds. 



2. Where- ]Joultry is kept upon a large scale obtaining and 

 handling earth in as large quantities as are necessary will greatly 

 increase the labor and the cost of applying the manure. Under 

 such circumstances, therefore the writer is inclined to indorse 

 the Maine system. Placing this upon the same basis as the other, 

 the proportions would be as follows: 



Fresh droppings, 100 pounds. 



Acid phosphate, 50 pounds, 



Kainit, 25 pounds. 



Dry sawdust, 30 pounds. 



This proportion of sawdust is slightly lower than that recom- 

 mended in the Maine bulletin. The total weight is 205 pounds, 

 but there is in practically all cases some loss of moisture and it is 

 suflicientl}' accurate for practical purposes to estimate the weight 

 of the mixture at 200 pounds. On this basis the composition would 

 be as follows: 



Nitrogen, 0.95 per cent.. 



Phosphoric acid, 4.25 per cent., 



Potash, 1.79 per cent. 



One ton of this mixture will supply: 



Nitrogen, 19 pounds, 



Phosphoric acid, 85 pounds. 



Potash, 36 pounds. 



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. 

 The fact should be kept in mind when planning 

 The use of poultry for the use of poultry manure that its con- 

 manure, stituents 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 

 mixtures as have been recommended are usually best used by 

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

 will not be found easy to make the materials sufficiently fine for 

 application with a fertilizer drill, but they can be successfully 

 applied with such a fertilizer distributor as the Greenwood or by 

 the use of a manure spreader. The quantity of poultry manure 

 to be applied must naturally be varied with soils and crops, but 

 it should be remembered that such manure well preserved mth 

 such mixtures as have been suggested are much stronger and richer 

 than ordinary manures and should be used in smaller quantities. 

 From about 1| to 2^ tons per acre will be the usualrange in quantity. 

 If poultry manure is to be used for potatoes the writer would 

 recommend substituting 8 pounds high grade sulfate of potash 

 in place of the 25 pounds of kainit recommended in the 2d and 

 3d mixtures. Poultry manures if unmixed of with the chemicals 

 in mixture No. 1 can probably be most profitably used as a top- 

 dressing for grass because of the high ])ercentage of nitrogen con- 

 tained in them.
