Differences in soil types, water table regimes, and technological inputs in smallholder
oil palm plantations on acid sulfate soil lead to the formation of distinct land units within the
plantations. There are four different land units identified, each with its unique characteristics.
These differences in characteristics result in variations in the properties and performance of
oil palm plants on acid sulfate soil. The objective of this research is to identify the land unit
that exhibits the best chemical properties of soil and the most favorable performance of oil
palm plants, as well as to study the influence of different characteristics of each land unit on
the chemical properties of soil and the performance of oil palm plants on acid sulfate soil.
Field surveys, soil sampling, and laboratory testing of samples were conducted from February
to June 2022 on each land unit of oil palm plantations on acid sulfate soil.
The research findings indicate that the land unit identified as LU 2, characterized by Alluvial
sulfic soil type, water table regime of -10 to -35 cm, and fertilization with 2 kg of Dolomite, 2.3
kg of KCL, and 2.3 kg of NPS per tree per year, along with a water management system
consisting of channels, dikes, and sluice gates, exhibits the highest pH, organic carbon content,
total nitrogen content, total potassium content, cation exchange capacity (CEC), and base
saturation (KB). LU 2 also shows the largest leaf area, number of bunches, bunch weight, and
oil palm production compared to LU 1 (Alluvial sulfic soil, water table regime of +40 to -10
cm, without fertilization and water management), LU 3 (Gleisol sulfic soil, water table regime
of +40 to -40 cm, fertilization with 0.8 kg of Dolomite and 0.8 kg of NPK per tree per year,
with water management through channels), and LU 4 (Gleisol sulfic soil, water table regime
of -30 to -120 cm, fertilization with 1.2 kg of Dolomite and 0.6 kg of Urea per tree per year,
with water management through channels).
Additionally, LU 4 (Gleisol sulfic soil, water table regime of -30 to -120 cm, fertilization with
1.2 kg of Dolomite and 0.6 kg of Urea per tree per year, with water management through
channels) exhibits the lowest organic carbon content, total nitrogen content, total potassium
content, and base saturation (KB) compared to LU 1, LU 2, and LU 3.
Finally, LU 1 (Alluvial sulfic soil, water table regime of +40 to -10 cm, without fertilization
and water management) shows the lowest plant height, stem girth, leaf area, bunch weight, and
oil palm production compared to the other land units.
