To quickly assess the difficulty of the text, read a short excerpt:
They served, however, a greater purpose even than Stockbridge dreamed at the time — they centered our thought and our study on the crop. From that time on we dis- cussed plant food and not soil food — plant feed- ing instead of soil manuring. *' Feed the crop rather than the soil " was a frequent expression at that time.
It is well to observe here that crop formulas were not new. Ville and others had published THE FIRST DEFINITE METHOD various sets. The Stockbridge formulas, how- ever, were uni...que in this: that they were based not alone on the analysis of the crop, but on its power of absorption from all the sources of fertility — from soil, air, and water. Thus Stockbridge boldly prescribed: " To produce fifty bushels of shelled corn per acre (without any stable manure) and its natural proportion of stover, more than the natural yield of the land, apply so many pounds each of nitrogen, potash, and phosphoric acid. Or, to produce a stated quantity of tobacco leaf of the desired color and texture, apply a stated quantity of plant food elements, preferably in the form of sulphates and nitrates." Here, then, for the first time, a definite way was prescribed to attain a definite object.
