Abstract

Sugarcane makes heavy demands on the replaceable soil nutrients and presages a loss in soil fertility due to monocropping, inadequate fertilization and non-recycling of the crop residue. Barnes (1974) showed that a 50 t crop removes, on average, 30–40 kg N, 22.7–27.2 kg P2O5 and 68 kg K2O. More recently, Zende (1990) has demonstrated the nutrient removal per ton of cane (Table 5.1).
