Abstrak/Catatan This research aims to study the influence of residual effect of biochar and the provision of compost and urea on soil physics of land inceptisol planted corn . The research was done in of the growing season second in land that has been containing residue biochar at the Station Ie Seum of University Farming, Aceh Besar. Soil sample was analyzed in the Laboratory Soil Physics and Land Environment of The Agriculture Faculty, Syiah Kuala University. Held from March until October 2013 . The research uses group randomized design, pattern factorials 2 x 4 with 4 remedial .There are two factors : ( 1 ) residue biochar : B0 = 0 tons ha-1 and B1 = 30 tons ha-1 . ( 2 ) a combination of compost and urea : K0 = without compost and urea , K1 = compost 0 ton ha-1 and urea 200 kg ha-1 , K2 = compost 30 ton ha-1 and urea 0 kg ha-1 , K3 = compost 30 ton ha-1 and urea 200 kg ha-1 . Parameter of the soil physics observed includes : bulk density, permeability, porosity, soil aggregate and water moisture content (pF 2,54 and pF 4,2). The research results show that the residue of biochar has no significant effect on bulk density, permeability, porosity, soil aggregate and water moisture content (pF 2,54 and pF 4,2). While a combination of compost and urea has significant effect on bulk density, permeability, porosity, soil aggregate and water moisture content (pF 2,54 and pF 4,2). The provision of compost 30 ton ha-1 and urea 200 kg ha-1 give the best result for all of the parameters of the soil physics properties. Key word : soil physics, residue biochar, compost, growing season second | |
