Estimating ground CO2 flux and its components in a stand of oil palm

Gabungan kaedah pengukuran dan ‘modelling’ telah digunakan untuk menganggarkan sumbangan tanah dan timbunan pelepah sawit yang reput terhadap fluks karbon dioksida (CO2) pada paras tanah di kawasan tanaman sawit. Maklumat ini diperlukan untuk merumuskan jumlah keperluan karbon untuh sistem berkenaan. Penafasan tanah secara keseluruhan (iaitu penafasan mikrobial dan akar) telah diukur menggunakan perangkap CO2 dan […]

Carbon dioxide enrichment in oil palm canopies and its possible influence on photosynthesis

This paper reviews past and recent work on at- mospheric concentrations of carbon dioxide (CO2)in and above stands of oil palm.Although data is limited, atmospheric CO2 concentrations both within and above stands,determined for several plantings,showed large diurnal variations with CO2accumulating to high levels over-night.Over much of the day, higher concentrations than are generally recognized as […]
