Abstract
This study uses Campbell Scientific’s Li8100 automated system to continuously measure CO₂ emissions from soil under different tillage practices, such as no-tillage, and various staple crops, including corn, wheat, and rye, in Almaty region. The study is motivated by the need to understand and mitigate greenhouse gas (GHG) emissions from agricultural soils that contribute significantly to climate change. The main objective is to estimate GHG emissions from arable light-dark chestnut soils under different fertilizers, tillage types and crops. The hypothesis is that different soil management practices and crop types significantly affect GHG emissions, with some practices being able to reduce emissions more effectively than others. Field studies were conducted in a foothill area where CO₂ emissions were measured under different combinations of crops and soil management practices. The results show that soil manure treatment leads to significantly high greenhouse gas emissions for all crop types studied. On the contrary, the use of mineral fertilizers in combination with no-tillage showed a small but positive effect on the reduction of greenhouse gas emissions. Among the crops, wheat showed the most significant reduction in emissions, which was associated with an increase in biomass and yield, suggesting that crop type and fertilizer application are crucial factors in managing greenhouse gas emissions in soil. The study concludes that while fertilizers have the potential to reduce greenhouse gas emissions, further research is needed to understand the complex mechanisms that cause these emissions. This study emphasizes the need for an integrated approach to resource efficient agriculture to develop effective strategies to reduce greenhouse gas emissions. Future research should focus on feedback effects in conservation agriculture to enhance sustainability and environmental protection.
