基于数量、长度和直径的计算。在一株4个月龄的冬黑麦植株上进行了根茎和根毛的测定。主、次、次、次、次四类根共13815672根，暴露面积2554.09平方公里。直径或根是它们所属类别的特征。活根毛覆盖了所有的根，总数为14,335,568,288根，总表面积为4,321.31平方米。总暴露的地下表面代表了结合土壤中单个植物的潜在土壤接触面。地下面积是外顶面积的130倍。
Calculations based upon the number, length, and diams. of roots and root hairs were made on a 4 months'' old winter rye plant. There were 13,815,672 roots in the categories (main, secondary, tertiary, and quaternary) with an exposed surface of 2,554.09 sq. ft. Diameters or roots were characteristic of the categories to which they belonged. Living root hairs covered all roots and numbered 14,335,568,288 with a total surface area of 4,321.31 sq. ft. The total exposed subterranean surface represents the potential soil contact surface of a single plant in binding soil. The subterranean surface was 130 times that of the external top surface area.
