Introduction and Historical Sketch. 
It has frequently been explained that the general scope and 
plan of the Rothamsted held experiments have included the 
growth of some of the most important crops of rotation, each 
separately, year after year, for many years in succession on the 
same land, without manure, with farmyard manure, and with a 
great variety of chemical manures — the same description of
