Studies on plant nutrition and effects of fertilizer use on sugarcane grown under different soil conditions in Guangdong province, 1996

Field trials evaluating sugarcane nutrition in Zhangjiang, Boluo and Panyu counties of Guangdong province have shown large responses to P, K, S and Mg. The best yield and economic returns were achieved with 450 kg K2O/ha, 202 kg P2O5/ha, 60 kg S/ha and 60 kg Mg/ha. The study attributed 5 to 10 percent of the yield increases to P2O5, 16 to 42 percent to K2O, 13 to 14 percent to S and 10 to 12 percent to Mg addition. The important contribution from each nutrient source proves the need for maintaining a balanced fertility approach. GUANGDONG-09
