The beneficial residual effects (post-effects ) of previous regular applications of chloride fertilizers on mature coconuts were evaluated in two long-term experiments conducted in an inland Tugbok soil (typic Tropudafs ) of Davao, Mindanao (Philippines). These studies invloved:Cl fertilizers (KCl, NaCl, and NH, Cl) at 0,80 kg Cl/tree/yr; and NaCl(Common salt) at increasing rates of 0.0,0.88, 1.76, 3.52 and 7.04 kg/tree/yr. Results showed clear evidence of positive residual effects of Cl fertilizers at 0.80 kg Cl/tree in terms of nut producction and copra (weight per nut and yiled tree) for 3-5 yr after regular fertilization of either KCl1, NaCl, or NH, Cl. Yield of coconuts remained at high levels as a result of leaf -Cl maintained at optimum levels (0.50% - 0.60% Cl, leaf #14), even without fertilizer application for the following 5yr. At higher rates of NaCl fertilizer (1.76-7.04 kg/tree/yr) applied regularly for 5yr, the residual response in terms of nuts and copra yield tended to occur for a longer period of 5yr. Except soil Na, soil properties were not significantly affected by NaCl application. |
