Impact of organic fertilizer substitution and biochar amendment on net greenhouse gas budget in a tea plantation

Waste generation nowadays is rising in the world and it seems hard to prevent it. Solid Waste Management (SWM) has been a major problem worldwide in most of the fast growing towns and cities among the developing countries all around the world. Food waste and green waste constitute high volumes of municipal solid waste (MSW). The application of compost in the agricultural sector can contribute to sustainable soil health and other co-benefits. The compost produced from biological waste does not contain any chemicals unfavorable to living soil. The objective of this research was to calculate the greenhouse gas emission from the compost processed from the food and green wastes generated on-campus in Universiti Teknologi Malaysia (UTM) as a pilot project. The result indicated that the composting process promotes the university as a green campus by converting organic wastes into valuable products such as organic fertilizer.

Weed Growth

The growth of weeds among agricultural crops is a pest that can decrease agricultural production by 47-87%. The aims of this research is to compare organic and an organic fertilizer and compare mechanical and chemical weed and pest control. This research employed a mixed-method, observation, in-depth interviews, and life cycle assessment. The greenhouse gas emissions were released are organic fertilizer 1,87 x 10-3 kg CO2 eq/ha and an organic fertilizer 15 x 101 kg CO2 eq/ha. Thereafter greenhouse gas emissions were released from mechanical control 1,87 x 10-3 kg CO2 eq/ha and chemical control 4,4 x 101 kg CO2 eq/ha. The totally of greenhouse gas emissions was released from dryland paddy farming in management phase is 19,4 x 101 kg CO2 eq/ha. Organic fertilizer more friendly than an organic fertilizer and mechanical control more friendly than chemical control. Mechanical control by farmers must be modified for the increase of effectiveness. The post-mechanical control should be those containing fruit and seed must be burned, meaning there will be not a longer any weed growth potential. Therefore, this mechanism will be able to realize potential production and sustainable dryland paddy farming.
