Phosphorus Loss of Phosphorus Fertilizer Applied to Tropical Peat Soils in Pineapple Cultivation

O.H. Ahmed, M.H.A. Husni and M.M. Hanafi

Abstract

This study was carried out to determine the efficiency using applied P under a conventional recommended fertilization regime in pineapple cultivation with residue removal. Results showed that P recovery from applied P fertilizer in pineapple cultivation on tropical peat soil was 53%. At 0-10 cm depth, there was a sharp decrease of soil total P, extractable P and soil solution P, days after planting for plots with P fertilizer. This decline continued till the end of the study. Soil total, extractable and solution P at the end of the study were generally equal to those before the study. There was no significant accumulation of P at 10-25 and 25-45 cm depths. However, P concentrations throughout the study period were generally lower or equal to their initial status. Recovery of P in pineapple cultivation on tropical peat soil seems to relate to P loss. As such, P loss needs to be considered in fertilizer recommendations for pineapple cultivation in organic soils.
