Agricultural practices are relevant to productivity and environmental impact, a contradictory and an intriguing debate. A single process of agricultural has been identified to emit greenhouse gas (GHG). Even agricultural components, consisting of soil, water, rice varieties, organisms and interactions among components its self, contribute to climate change. Investigation of CO2, CH4 and N2O emission levels needs to be strictly, especially on degraded agricultural land. Thus, soil processing, rice varieties, irrigation patterns, fertilization applications and pesticides are carried out as environmental mandates. The authors recommend the use of low-emission varieties, intermittent water management, agroforestry applications and biochar amendment from agriculture, estate and forest residue to minimize environmental impacts. Application biochar, compost and liquid smoke (3 in 1 technology) in agriculture and forest plantation its can be reduce CH4, N2O and CO2 emission gas and increasing the yield of agriculture.
