The field capacity of a soil is 25%, its permanent wilting point is 15% and specific dry unity weight is 1.5. If the depth of root zone of a crop, is 80 cm, the storage capacity of the soil, is-A-8 cmB-10 cmC-12 cmD-14 cmE-16 cm-C-12 cm

Question

APTITUDE CRACK · Accepted Answer

The correct option is  C 12 cm For formula is (Yd/Yw)*d*(field capacity permanent welting point); Given data: Yd=1.5, Yw=1, Depth zone=80 cm, Field capacity = 25% = 25/100 = 0.25, Permanent wilting point = 15% = 15/100 = 0.15, So, (1.5/1)*80*(0.25 0.15) = 12 cm, The Correct answer is 12 cm.
