Comparative Analysis of Volatile Organic Compound (Voc) Emission Levels Across Different Tillage Operations and Tractor Speeds in Agricultural Practices

Abstract: This study investigates the emission levels of Volatile Organic Compounds (VOCs) across different tillage operations and tractor speeds in agricultural practices. A field experiment was conducted on a 14.4-hectare farmland using four tractor models (MF new, MF old, NH new, NH old) at three different speeds (15 km/h, 20 km/h, and 24 km/h). The tillage operations included 1st plough, 2nd plough, harrowing, and ridging, with a total of 432 experimental runs. VOC emissions were monitored using a Multireal Pro Handheld Gas Analyzer. The results indicate that the highest VOC emissions occurred at 20 km/h, while at 24 km/h, emissions remained relatively stable across all tillage operations. Among the tillage operations, ridging and 1st ploughing exhibited the highest VOC emissions, while harrowing consistently produced the lowest. These findings emphasize the need for speed regulation and optimized tillage operations to mitigate environmental impact. Future research should explore sustainable tillage practices and emission control technologies to promote environmentally friendly farming.
