PENGARUH KOMBINASI AMELIORAN DAN PUPUK TERHADAP EMISI GAS RUMAH KACA ( CO2 DAN N2O ), PADA LAHAN GAMBUT KALAMPANGAN DI KALIMANTAN TENGAH

Abstract

Peat soil is formed from a pile of remains of dead plants, whether they have weathered or not. Peatland has the potential to be used as an area for agricultural business development, but there are several obstacles that must be overcome one of the efforts to do is the use of soil amelioration materials. However, the use of ameliorant can cause the formation of greenhouse gases. This study aims to determine the effect of a combination of ameliorants and fertilizers on greenhouse gas emissions on peatlands. This research is a field trial using a completely randomized design (RCD) 1 factor, that is ameliorant treatment consists of 4 treatments : A1D1 (50% cow's pile + 50% ash from in situ weeds + base fertilizer and NPK with dose 100-200-120 kg/ha), A1D2 (50% cow manure + 50% ash from in situ weeds + fertilizer basic and NPK with dose 150-300-180 kg/ha), A2D1 (50% cow manure + 50% compost from in situ weeds + basic fertilizer and NPK with dose 100-200-120 kg / ha), A2D2 (50% cow manure + 50% compost from in situ weeds + basic fertilizer and NPK with dose 150-300-180 kg / ha). The results of this study indicate that the application of ameliorant material with various combinations does not have a significant effect on CO2 gas, and NO2 gas.
