BARNYARD MANURE 99 



If the manure is coarse, it should be plowed under as long in 

 advance of planting as possible, so that it may have ample time 

 in which to decay and thus make available the plant food which 

 it contains ; but if it is well rotted, early plowing in is not so 

 important. A manure spreader is recommended for every stock 

 farm, as it saves labor and spreads the manure evenly, thus 

 causing the manure to go farther and bring a larger return.
