Abstract
The aim of this study was to analyses the soil in different type of agriculture soil based
on physical properties and results from FTIR. The type of agriculture area involved were
oil palm (site 1), sugarcane (site 2), rubber (site 3), lime (site 4) and banana (site 5). The
physical appearances of samples were analysed using stereomicroscope from lower to
higher magnification for a better impression. The gravimetric water content method was
used to determine samples moisture content. The colours of samples were analysed
using comparisons the soil samples colour with Munsell Colour Chart. The samples were
then analysed using ATR-FTIR and the results interpretation were presented by
statistical analysis (PCA). The physical appearances of soil samples from site 1 showed
consistency at all depths and points while the soil samples from site 4 appeared to has
clay likes particles that distinguish them from other samples. The moisture content
analysis revealed that site 4 has the wettest followed by site 3, site 5, site 2 and site 1.
All soil samples have yellow or yellowish red colour and some of the samples were
classified as dark soil because moistened the soil in this did not decrease their colour
lightness. Based on ATR-FTIR, all soil samples were characterized as inorganic soil and
the PCA result showed the differences between samples from site 1 and 2 and other
sample from site 3, 4 and 5.
