The effects of liming on an ultisol in Northern Zambia

Communications in Soil Science and Plant Analysis, 1988
Abstract Only a few reports have been made on long‐term liming experiments on Ultisols and Oxisols in Africa. This series of experiments on an Ultisol in northern Zambia, beginning in 1978, were used to measure the effects of liming with continuous cultivation in an area which receives about 1200 mm annual rainfall in a 7‐month period.
