The impacts of minimum tillage planting of sugar cane and mulching on surface/subsurface runoff, soil loss and agrochemical movement were studied in Mauritius from 1998 to 2000, in a silty clay loam having a 5 per cent slope and receiving an annual rainfall exceeding 3000 mm. Less than 7 per cent of annual rainfall was dissipated as surface and shallow subsurface (<90 cm) runoffs. With the current practice of lining trash in alternate interrows, maximum soil loss was 1.8 tonnes/ha/year. Due to the rapid dissipation of the agrochemicals, their offsite movement was low, being less that 0.25 per cent of the herbicides applied, 3 kg N/ha/year, and 1 kg P/ha/year. This insignificant movement of soil and agrochemicals was influenced more by rainfall intensity than bmulching or tillage. The present study showed that current cultural practices are adequate for sustainable cane production in Mauritius. | |
