3.2 Relationship between different soil properties
The soil pH and EC correlated significantly (r=0.37, p<0.01)
with each other (Table 3). The Fe had significant and negative (r=-0.46,
p<0.01) correlation with soil pH whereas it was significant
and positive with Mn (r=0.13, p<0.05) and Cu (r=0.23,
p<0.01) and non-significant with Zn. The EC strongly and
positively correlated with K (r=0.37, p<0.01) and Mg (r=0.29,
p<0.01) whereas it was negatively correlated with Na (r=-0.17,
p<0.01). The SOC and BD had a significant and negative
correlation (r=-0.32, p<0.01). The K content correlated
significantly with Na (r=0.30, p<0.01) and Mg (r=0.37,
p<0.01). It was interesting to note the highest, significant
and positive correlation (r=0.60, p<0.01) between the Fe and S
content.
