Retention and leaching of nutrients in a limed ultisol under cropping


, : Retention and leaching of nutrients in a limed ultisol under cropping. Soil Science Society of America Journal 54(4): 757-761

In glasshouse trials 0, 1.3, 2.1, 3.0, 5.0 or 6.5 t lime/ha was applied to maize sown on acid Ultisol soils from S. Nigeria to give the initial pH values 4.3, 5.0, 5.4, 5.0, 6.5 and 7.1, resp. The greatest response to liming after 10-wk growth was attained by increasing the pH from 4.3 to 5.0, which increased maize yields from 150 g DM/pot to about 350 g.
