Abstract

Soil response including carbon dioxide emission under the combination of compaction, fertilizer and soil moisture were investigated in a screenhouse. The factorial experiment consisted of two levels of moisture contents (50% and 70% field capacity, FC), three levels of compaction (0, 2 and 4 kg weights) and fertilizer treatments consisted of control, biochar, organic fertilizer + urea (FertC), urea intercalated biochar + organic fertilizer (FertD). Carbon dioxide (C02) evolution was determined using static chamber approach. Saturated hydraulic conductivity (Ksat), unsaturated hydraulic conductivity at 2 cm suction (K2cm), bulk density, total porosity, soil mean weight diameter, geometric weight diameter and organic carbon were determined using standard methods and the data was subjected to analysis of variance at 5% probability level. FertC in soil compacted under 2 kg and at 50% FC significantly enhanced (P
