 Spring Application versus Winter Application of Fresh Manure. 



WINTER APPLICATION OF MANURE (FRESH) verSUS SPRING APPLICATION (STACK). 



In this experiment, 16 tons per acre of manure were weighed and hauled on 

 the plot in the winter and left in the stack, to be spread in the spring. The other 

 plot received fresh manure direct from the yard in the spring. Spring application 

 again produced a somewhat heavier yield of mangels, but results will be accepted 

 as final only after further verification.
