Abstract :
This study assessed soil pH and organic matter
in central and southern zones of Plateau state. Stratified
random sampling method was adopted for collecting the
soil samples, and a total of 736 samples covering the total
area were collected. The physico-chemical characteristics
of the soil samples were analyzed at the laboratory of the
Centre for Dry Land Agriculture (CDA) located within
Bayero University Kano (BUK) in Nigeria. The soil pH
and organic matter values for the collected soil samples
were determined by Potentiometric 1:2 pH-m and
Walkely and Black methods respectively. The values of
the parameters were entered in attribute table and linked
with the ArcGIS 10.8 to develop a relational database.The investigation involved employing the Inverse
Distance Weighting (IDW) interpolation method to create
a spatial representation of soil pH and organic matter
distribution.The
investigation also involved conducting Pearson's product
moment correlation analysis between soil pH and organic
matter across multiple soil sample locations, utilizing
SPSS version 25, a statistical software package. The result
obtained for the correlation co-efficient γ is –0.071 and
the p-value is 0.055 using 0.01 level of significance showed
that; the association or relationship between soil pH and
organic matter is weak, since 0.071 is less than 0.3, they
have a negative relationship, which means that they move
in an opposite direction, and that an increase in soil
organic matter leads to a decrease in soil pH and vice
versa; the association between the two variables (soil pH
and organic matter) is insignificant, since the p-value
0.055 is greater than the level of significance + 0.01. The
study recommends that farmers should be discouraged
from the slash and burn practice which does not allow for
the decomposition of organic material to enhance the
organic matter content of the soil.
