286 agriculture: o^ mains. 



These figures are computed for first class unleached manure, 

 so I would advise using about double the quantity. This is 

 shown in the last column. 



It is generally understood that ordinary farm manure has lost 

 much of its value before it is applied on account of not being 

 properly cared for. In most cases it is thrown out of doors 

 and left to leach, or in case of horse manure, to burn up, and 

 what is left is applied to the land as so much humus. The 

 small per cent of soluble ingredients left go a little way toward 

 orchard renovation. 



Good bam manure is without doubt the best general fertilizer 

 that can be applied to the orchard. It not only supplies the 

 required fertilizing elements but improves the physical condi- 

 tion of the soil by the addition of humus, which aids in the 

 retention of moisture, and the warming of cold clay soils. For 

 orchard work the manure should be spread on and plowed 

 under, say four inches deep, and thoroughly cultivated. 



In the table on Farm Manure for the convenience of those 

 keeping different farm animals I have added two combinations 

 so as to show the per cents of nitrogen, phosphoric acid and 

 potash found under each condition. A farmer keeping only 

 cows would use No. i ; keeping only horses No. 2 ; and so on. 

 Where the cow and horse manure are mixed and kept well 

 pitched over use No. 6; and where a lot of hogs are kept on 

 the dressing use No. 7.
