Paper pulp was evaluated, with reference to lime, as a soil amendment to a tropical acid soil (typic Kandiudult). Rye grass(Lolium perenneL.) was grown under greenhouse conditions. Amendments were applied at rates to attain target pH values of 5.5,6.0, and 6.5. Paper pulp and lime were equally effective in increasing dry matter production. Similar to lime, paper pulp provided high calcium (Ca) inputs and alleviated aluminum (Al) and manganese (Mn) toxicity. Paper pulp can be applied to a tropical acid soil as a lime substitute.
