Effect of Compost Combination on Methane Emission in Undisturbed Acid Sulphate soil in South Kalimantan of Indonesia
Annisa, Wahida, Maas, Azwar
A greenhouse experiment was conducted to examine the cumulative methane (CH4) emission in paddy soils and correlation with soil redox potential (Eh), soil pH and plant growth. The experiment was arranged in two factorial randomized block designs with three replications. The first factor was a kind o...

Emissions of Methane and Nitrous Oxide from Rainfed Rice Field Treated with Different Rice Planting Systems and Nematicide Applications at Central Java, Indonesia
Wihardjaka, Anicetus, Harsanti, Elisabeth Srihayu
Rice field is issued as a source of greenhouses gases (GHGs) emissions especially methane (CH4) and nitrous oxide (N2O). Rice cultural approach could mitigate GHGs emissions i.e. through rice planting systems and nematicide application. The field experiment was conducted in rainfed rice field at Pat...

Response of Maize Grown on Overburden Soil in a Coal Mining Area without Top Soil to Various Compost Sources
Purnomo, Erry
Soil in Kalimantan Island is considered infertile. To obtain a reasonable crop yield a high input fertilizer package should be applied. The situation will be worsening when an open pit system of coal mining adopted. Failure in re-arranging the soil layers can result in decreasing soil fertility comp...
