Studies with 15 N showed that less than 5 per cent of applied N (commonly applied at rates between 100 and 150 kg/ha) would pollute water resources in Mauritius and that less than 30 per cent was utilized by the crop. As a result, the approach to fertilization has changed, with little importance being attached to leaching losses (found to be insubstantial) and recognition of the lack of need to delay fertilization until development of an extensive root system by plant cane; application of complete NPK fertilizers (P and K giving best results when applied in the furrow at planting) has simplified fertilization. There is no longer any urgency to fertilize ratoon cane immediately after harvest. Close matching of N supply with cane demand has improved utilization efficiency. However, yields have not increased as a result of the changes. | |
