Many factors influence a plant's uptake of boron from the soil, but one key factor is soil type. One experiment† compared plant content C of boron, in parts per million, with the amount B, in parts per million, of water-soluble boron in the soil. In Decatur silty clay the relation is given by C = 33.78 + 37.5B.In Hartsells fine sandy loam the relation is given by C = 31.22 + 71.17B. (a) What amount of water-soluble boron available will result in the same plant content of boron for Decatur silty clay and Hartsells fine sandy loam? (If you choose to solve this problem graphically, we suggest a horizontal span of 0 to 0.5 for B. Round your answer to three decimal places.) part per million(b) For available boron amounts larger than that found in part (a), which of the two soil types results in the larger plant content of boron?
