Changes in soil pH and EC
The impact of biochar application on soil pH and EC values is
shown in Table 1. The statistical analysis showed a significant
(p< 0.05) increase in pH and EC due to addition of biochar.
The highest mean values of pH and EC were recorded in soils
treated with 5.0% biochar, while the lowest values were found
in the untreated soil. The values of soil pH increased by 0.16–
0.17 unit at the highest application rate. Meanwhile, the EC
values increased from 1.97–2.10 dS m1 to 2.60–2.93 dS m1
for 5.0% biochar.
