Acid soils(ASS) are widely distributed in Australia. This has only been recognized recentlywhen intensive research on ASS has been done in this country. This paper reviews aspects concerning a)the distribution and acid potential, b) controls on acidic status, and c) problems and management of ASSin Australia It is believed that the Australian experience may be useful for other countries where potentialproblems from ASS exist but insrfficient attention was paid to them.
