What reading level is Productive Soils the Fundamentals of Successful Soil Management And Profitable book?
To quickly assess the difficulty of the text, read a short excerpt:
The land was then left in grass without manuring or fertilizing for fifty years. The yields of hay were compared with those on a simi- lar field on which no fertilization was made. The average increases in yield for each decade, resulting from the previous applications of manure, were fifty-seven, twenty-four, six, fifteen and twenty- eight per cent, respectively. 10 Manure Not a Perfect Fertilizer. General results demon- strate conclusively that manure alone cannot maintain fertility nor can i...t be used exclusively in regenerating soils. The continued use of such manure on many dairy farms has led to an unbalanced condition in the soil. Oat crops especially, secure so much nitro- gen that they lodge badly. Many dairy farmers who purchased "run-down" farms, and who sought to improve the soil through the use of manure, have found that phosphate fertilizers, in particu- lar, are quite necessary to supplement the manure to give the results desired. On sands, the reinforcing of the manure with both phos- phates and potash proves most profitable.
