This study focuses on sand dune stabilization projects in the Baiji District of Iraq, aiming to reduce the mobility of shifting sands and mitigate wind erosion. Petroleum-based mulches were applied to create a surface crust that effectively immobilized sand movement. The findings confirmed the effectiveness of petroleum mulch in protecting infrastructure and farmland from encroaching dunes. The paper also discusses environmental concerns, mulch durability, and the potential for integrating vegetation in stabilization efforts.

This 2009 study by Harper and Ferguson, published by Cambridge University Press, evaluates the impact of petroleum mulch and sowing time on the establishment and yield of oilseed sunflower (Helianthus annuus L.). Results showed that petroleum mulch enhanced seedling establishment, conserved soil moisture, improved plant resilience under stress, and reduced weed competition. Additionally, optimal sowing times significantly influenced plant growth and yield. The combined use of petroleum mulch and appropriate sowing time led to notable yield improvements, offering a sustainable strategy for sunflower oil production.

This three-year study conducted in Mississippi evaluated the effects of petroleum mulch on soil temperature, seedling emergence, weed control, and cotton yield. The findings revealed that petroleum mulch increased soil temperature in the germination zone, reduced soil crusting after rainfall, improved plant stands, and significantly boosted cotton yield—especially when applied in 6-inch wide bands. Combining the mulch with preemergence herbicides like trifluralin further enhanced weed control. However, the practical challenges of cost, handling, and application at scale remain important considerations.
