The potato fields received manure on all except three farms in this area. 

 Labor in hauling manure varied chiefly with the number of loads hauled. The 

 method of handling also made a difference. Some farmers did not have 

 spreaders and hauled in carts and spread by hand. On one farm the manure 

 was hauled out in winter and piled and spread the following spring. Most of 

 the work on manure is done at times when it does not interfere with other 

 crop worK.
