| Summary: | An experiment was conducted to evaluate the effect of soil compaction levels and biochar addition on some soil physical parameters, namely; bulk density, particle density, soil porosity, hydraulic conductivity and infiltration. It included two factors: soil compaction with two levels of 0 and 2 kg and biochar addition with two levels of 0 and 2 %. The results showed that the soil compaction of 2 kg significantly affected in the bulk density, soil porosity, and hydraulic conductivity comparing with the soil compaction 0 kg, with no significant effect on particle density and infiltration. Meanwhile, 2 % biochar addition significantly affected in the bulk density, soil porosity, and hydraulic conductivity compared with 0 % biochar addition, with no significant effect on particle density and infiltration. Moreover, the results showed that the interaction between soil compaction and biochar addition led to a significant effect giving lowest bulk density 0.99 Mg m-3, particle density 2.42 Mg m-3, hydraulic conductivity 1.46 cm h-1, and highest soil porosity 59.20 %, with 0 kg soil compaction and 2 % biochar, but lowest infiltration 8.10 cm h-1 with 2 kg soil compaction and 2 % biochar. |
