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.
