Mate, Even I was curious about this during the exam and I'm pretty sure the answer is that since laterite soil is formed in conditions of heavy rains and alternate wet and dry period whereas Black soil is formed due to denudation of volcanic rocks. Therefore laterite soil looses all its nutrients (leached) whereas black soil doesn't.
