What reading level is The Farm That Won't Wear Out book?
To quickly assess the difficulty of the text, read a short excerpt:
05 an acre was invested in groundraw rock phosphate with a rotation of corn, oats, wheat and hay(clover and timothy), and the value of the increase produced by thephosphorus amounted to $5. 85 as an average for the twelve years, andto $8. 41 as an average for the last four years. Thus the profit wasfrom about 560 to 800 per cent on the investment, counting corn at35 cents a bushel, oats at 30 cents, wheat at 70 cents, and hay at$6 a ton. These figures represent the increase produced byphosphoru...s over and above the value of the crops grown withoutphosphorus fertilizer. In this case no farm manure was used oneither part of the field; but commercial nitrogen and potassium wereapplied alike on both parts, and clover was grown in the rotation.
Acid phosphate was also used in direct comparison; and, in answer tothe question whether the general farmer should apply liberal amountsof finely ground natural rock phosphate, or whether he should payfour times as much for phosphorus after the fertilizer manufacturerhas mixed one part of the raw rock with one of sulfuric acid andthus produced two parts of acid phosphate, these Pennsylvaniaexperiments tell us that the yearly average for the twelve yearsgave a gain per year of $2.
