Soil Enzymes and Antioxidants Activities of Edible Vegetables Grown in Soils Polluted by Gas Flaring.

Associated gas flaring has several consequences on the environment. This study was aimed at assessing the impact of gas flaring on soil enzymes and plant antioxidant activities from gas flare-bearing communities in Nigeria. Soil and plant samples were obtained from farmlands in Ukwa West and Izombe gas flaring sites, as well as unpolluted site from Olokoro (used as control).

Biochar Remediation Improves the Leaf Mineral Composition of Grown on Gas Flared Soil.

This study evaluates the effects of remediation of gas flared soil by biochar on the nutritional composition of cultivated leaves, relative to non-gas flared soil. Gas flared soils are degraded due to the presence of heavy metals, noxious gases, carbon soot and acidic rain. Biochar produced from oil palm fibre was applied at five different amounts: 0 t ha, 7.
