Abstract

Pineapple is one of the important crops in Sarawak that can grow successfully on peat as it is tolerant with peat soil conditions. Intensive cropping system can cause nutrient pollution to the surface water commonly in term of nitrogen (N) and phosphorus (P). the objectives of this study is to determine the extent of nutrient pollution (N, P and K) in the drainage ditches and to relate the nutrient concentrations to those in the peat soil and the fertilizer management at the pineapple farm. Water and soil samples were taken at pre-, post- and in between fertilization from a smallholders pineapple farm in Asajaya. The samples were used to determine the bulk density, cation exchange capacity (CEC), pH and nutrient concentration. Results indicate the nutrient concentration in the surface water and peat soils were high during the early stage of fertilizer application but decreased afterwards. Based on national and international benchmarks, nutrient Nand K were well within the safety level, but P exceeded the safety level. P pollution was attributed to the high porosity and low retention capacity of the peat soil.
