In the cultivation of sugar cane in Hawaii irrigation water is applied at very high rates. More than half of this water returns to the basalt aquifer by infiltrating through the highly permeable lateritic soils. The excessive rate of irrigation alters the composition of the ground water and accelerates the evolution of the low humic latosols to humic latosols.
