Abstract (AB)The variation of soil exchangeable Ca and Al with pH has been studied and used to explain the yield response of sugarcane to liming acid soils of Mauritius. Liming did not improve the yield of sugarcane. This may be attributed to absences of Mn and Al toxicities and to the presence of a good Ca status in the soils. Soil investigations indeed showed that at pH greated than 5 .0 exchangeable Al was reduced to negligible values while exchangeable Ca saturated more than 70 per cent of the cation exchange sites and was not appreciable increased upon liming. Application of high doses of lime residue to soils may, on the contrary, depress the yield of sugarcane. The cause of this adverse effect of lime residue on sugarcane yield however remains unknown in Mauritius. From the close association that exists among pH and soil exchangeable Ca and Al, liming acid soils under sugarcane in Mauritius should only become an indispensable practice when the soil pH falls below 5.0. Liming recommendations should therefore be aimed to raise the soil pH to 5.0 or 5.5.
