What reading level is Dry-Farming : a System of Agriculture for Countries Under a Low Rainfall book?
To quickly assess the difficulty of the text, read a short excerpt:
On a poor clay soil it required 1109 pounds ofwater to produce one pound of dry matter, while on a rich calcareoussoil only 574 pounds were required. Gardner of the United StatesDepartment of Agriculture, Bureau of Soils, working in 1908, on themanuring of soils, came to the conclusion that the more fertile thesoil the less water is required to produce a pound of dry matter. Heincidentally called attention to the fact that in countries oflimited rainfall this might be a very important principle... to applyin crop production. Hopkins in his study of the soils of Illinoishas repeatedly observed, in connection with certain soils, thatwhere the land is kept fertile, injury from drouth is not common, implying thereby that fertile soils will produce dry matter at alower water-cost. The most recent experiments on this subject, conducted by the Utah Station, confirm these conclusions. Theexperiments, which covered several years, were conducted in potsfilled with different soils. On a soil, naturally fertile, 908pounds of water were transpired for each pound of dry matter (corn)produced; by adding to this soil an ordinary dressing of manure'this was reduced to 613 pounds, and by adding a small amount ofsodium nitrate it was reduced to 585 pounds.
