Effective Farming 



Influence of litter on manure. The kind and quantity of 

 litter used has much to do with the composition of the manure. 

 For example if sawdust and shavings are the bedding material, 

 there is less fertility than if oat straw is used and, in addition, 

 oat straw decomposes more rapidly than shavings or saw- 

 dust, which is an advantage. Also, if manure contains a large 

 proportion of litter, obviously it is less valuable than if it con- 

 tains a smaller quantity.

Influence of class of animal on manure. The composition 

 of the manure from the different classes of animals is different. 

 Thorne has found that as an average of several analyses made 

 by the experiment stations in Ohio, Connecticut, and New 

 York, horse manure with straw contains .57 per cent nitrogen, 

 .12 per cent phosphorus, and .54 per cent potassium, and cow 

 manure with straw contains .46 per cent nitrogen, .13 per cent
