Pineapple Residue Ash Reduces Carbon Dioxide and Nitrous Oxide Emissions in Pineapple Cultivation on Tropical Peat Soils at Saratok, Malaysia

Burning pineapple residues on peat soils before replanting raises concerns hazards of fires. A study was conducted to determine whether ash produced from could be used minimize carbon dioxide (CO2) and nitrous oxide (N2O) emissions in cultivated tropical peatlands. The effects residue fertilization CO2 N2O a soil grown with were determined using closed chamber method the following treatments: (i) 25, 50, 70, 100% suggested rate + NPK fertilizer, (ii) (iii) only. Soils treated (25%) decreased relative without due adsorption organic compounds, ammonium, nitrate ions onto charged surface through hydrogen bonding. ability maintain higher pH during growth primarily contributed low emissions. Co-application compound fertilizer also improves ammonium availability, fruit quality pineapples. Compound fertilizers can amended reducing productivity.
