BULLETIN 614, U. S. DEPARTMENT OF AGRICULTURE. 



Considering the orchardists in the North Yakima district who 

 actually apply manure, regardless of method or crew used, it requires 

 7.70 man hours and 13.93 horse hours to apply 4.78 tons per acre, 

 at a cost of $11.20 for both material and labor, while in the Zillah 

 district it requires 12.06 man hours and 20.73 horse hours to apply 

 7.72 tons per acre at a cost of $17.71 for both material and labor. 

 Considering only those orchardists in both districts who actually 

 manure, it requires 9.65 man hours and 16.96 horse hours to apply 

 6.09 tons per acre at a cost of $14.10 for material and labor. Seventy- 

 six per cent of all orchardists under mulch-crop management and 77 

 per cent under clean-cultural management manure each year. 

 However, considering the small amount of manure produced on the 

 average ranch and the small acreage covered each year, much more 

 was actually applied on the latter than on the former, the latter 

 applying 6.74 tons and the former 4.99 tons per acre. 



Different methods are used in applying manure, some men using 

 a sled and others a wagon for hauling purposes. Manure is applied 

 during the fall and winter months, usually being spread from the 

 sled or wagon as the hauling is done. A few, however, put it in 

 piles and spread it at their convenience. If there are certain trees 

 which seem to need manure more than others, it is applied to these 

 trees rather than spread uniformly throughout the orchard. Eighty 

 per cent of the orchardists manuring each year use a one-man and 

 two-horse crew, and 12 per cent use a one-man and one-horse crew. 

 The remainder use a crew of two men and two horses.

Table XIII shows that more manure is applied per acre in the 

 Zillah than in the North Yakima district, also that 2 tons more are 

 applied per acre on orchards under clean-cultural management than 

 those under mulch-crop management. There is little difference in 

 the time consumed in applying manure under the different conditions.
