Abstract: The decomposition rate of polyolefin film used as an agricultural mulch is controlled by the incorporation therein of 3 to 20 percent of a cation exchanged sulfonated petroleum coke or cation exchanged wet air oxidized petroleum coke. The film also contributes ion exchange capacity to the soil, furnishes nutrients and improves the tilth of the soil. Other additives such as nematocides or fungicides can be incorporated in the film mulch.
