Abstract
Encroachment of oil palm (Elaies guineensis) into coastal sandy soil previously deemed as unsuitable has been an increasing trend due to prime land scarcity. Major limiting factors are poor water retention and high leaching of nutrients from granulated chemical fertilizers. The effect of slow-release fertilizer (SRF) on nitrogen (N) and phosphorus (P) contents in two years old oil palm in coastal sandy soil was studied at a smallholder estate using a Randomized Complete Block Design with five treatments of equivalent 1000g N replicated four times. The treatments were 100 NPK (T1) 50 NPK 50 SRF (T2) 100 SRF (T3) 50 NPK EFB Compost (T4) and 50 SRF EFB compost (T5). There were no significant differences in the mean leaf area and mean bole diameter. There were significant differences in soil Total N ranging from 1333.10 to 1523.15 ppm as ANOVA indicated p 0.026. T5 was significantly different from T1 and T4 but not from T2 and T3. In addition there were no significant differences among T1 T2 T3 and T4. However no significant differences were obtained in plant N ranging 1738.50 to 1893.07 ppm with ANOVA indicating a p 0.336. Mean soil available P (0.89 - 1.00 ppm) and plant P (1056.04 - 1165.97 ppm) showed no significant differences with the ANOVA indicating p values of 0.370 and 0.161 respectively. The study concluded the combination of SRF and EFB compost is recommended as an alternative fertilizer for oil palm in the coastal sandy soil area.
