They selected plots of ground —in some they tried different manures, while on one plot no manure or change of crop was allowed, but wheat followed wheat, season after season, for 40 years. In that time there has been a decrease of just 10 bushels per acre in the yield. One fourth bushel per acre a year. Taking this as a standard case, farmers who follow wheat with wheat not giving the land any needed rest, or feeding it with manure or green crops turned under, may look for a decrease, of course less some years than others, but an average of onefourth bushel per acre a year.
