Soybean responded to lime up to the rates of 1700 and 550 kg CaCO3 ha-1 for Bachieng and
Hoythakoune soils, which appears to be a preliminary liming rate for soybean production in these two
soils. Liming had beneficial effects on soybean production on these two acid upland soils. In
Bachieng and Hoythakoune soils, the data indicated that pH was increased from 4.4 to 5.3 and 4.7 to
6.0 respectively. Future experiments should explore additional lime on the Bachieng soil. Apart from
pH, lime increased concentration of P, Ca, Mg and decreased Al and Mn in these two soils. The
dominance analysis of the soybean yields in Bachieng and Hoythakoune sites indicated very high
returns to the addition of limestone.
