Abstract: This study investigates the effect of the soil deflector’s opening angle on the quality of soil processing and uniform fertilizer distribution in agricultural activities, particularly in orchards and vineyards. The soil deflector temporarily blocks soil movement, facilitating the penetration of fertilizers into the soil, improving their integration with the soil environment. The dynamics of normal forces acting on soil particles are analyzed to understand their influence on the deflector's operational effectiveness. Results indicate that an opening angle between 54° and 66° significantly improves soil processing efficiency, achieving both uniform fertilizer application and optimal energy usage. The experiments explored variations in the soil deflector’s opening angle from 50° to 80° at speeds of 6 km/h and 8 km/h. Findings demonstrate that within the optimal angle range, the depth and width of fertilizer application improve markedly, ensuring better soil and nutrient management. The study further highlights that the resistance faced by the deflector decreases at smaller angles, whereas larger angles increase energy consumption and reduce fertilizer distribution efficiency. The research concludes that optimizing the soil deflector's opening angle is crucial for enhancing soil processing performance, improving fertilizer application uniformity, and minimizing energy expenditure. These results provide practical guidelines for the development of agricultural machinery that meets the needs of modern, resource-efficient farming practices, particularly in specialized environments like orchards and vineyards.

Abstract: Since coal is the most used commodity for electricity supply, several coal mines have been abandoned. These coal mines have resulted in releasing a chemical compound known as polycyclic aromatic hydrocarbons (PAHs). Coal is the second largest resource after oil, and it has multiple uses in several applications. Coal mining and its impact on the environment has exacerbated the quality of water. Ben(a)pyrene (BaP), one of the most toxic pollutants has been given attention according to the World Health Organization (WHO) as the most toxic pollutant amongst the 16 PAHs that are mostly found in water bodies and contact with humans. It is also known to be highly concentrated in coking wastewater and poses significant health implications of having carcinogenic properties which have urged for its sequestration. Several technologies have previously been employed in mitigating the challenges however, the limitations of these technologies have resulted in suggesting an alternative method that could be introduced. In this review, these techniques are being reviewed and discussed on the fate of BaP-PAHs in coking wastewater. The advanced oxidation method has been considered as the most preferred method in aiding to sequestrate BaP-PAHs however, some studies have proven that the biological method using mushrooms can be used in sequestrating BaP-PAHs. However, the future perspective in determining the fate of BaP-PAHs can be considered in functionalizing the mushrooms with a metal oxide in aiming to sequestrate PAHs in coking wastewater.
