One ton of this mixture will supply about : 



Nitrogen. 16 pounds, 



Phosphoric acid, 70 pounds, 

 Potash, 30 pounds. 



2. Where poultry 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 

 sufficiently 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 poul- 



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



alkaline and will release ammonia, thus 



causing greater loss than would occur if nothing were mixed with 



the manure. 



The fact should be kept in mind when 

 The use of poultry planning for the use of poultry manure 

 manure. that its 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 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 mate- 

 rials sufficiently fine for application with a fertilizer drill, but they 

 can be successfuly applied with such a fertilizer distributor as the 

 Greenwood or by the use of a manvire 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 with such mixtures as have been suggested are much 

 stronger and richer than ordinary manures and should be used in 

 smaller quantities. From about 1/4 to 2>^ tons per acre will be 

 the usual range 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 uninixed or with the chemicals in 

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

 dressing for grass because of the high percentage of nitrogen con- 

 tained in them.
