    Liming and Compost Amendment of Heavy Metal Contaminated Soil Reduced Pb Accumulation in Ocimum gratissimum L, Enhanced Secondary Metabolism and Chlorophyll Formation
    Author(s): Sifau Adejumo* and Rosilu GO

    Soil contamination by heavy metals limits plant metabolic processes and development. Technique that immobilizes metal in the soil and reduced uptake by crop is preferred. Effects of liming and compost amendment on Pb immobilization and secondary metabolism of Osmium gratissimum L. planted on lead-acid battery wastes contaminated soil were studied. Four levels of lime (0 ton/ha, 2 ton/ha, 4 ton/ha and 8 ton/ha) and compost (0 ton/ha, 10 ton/ha, 20 ton/ha and 30 ton/ha) were used while uncontaminated and contaminated soil without amendments served as checks. Data were collected on growth and yield parameters, nutrient uptake, leaf chlorophyll and secondary metabolites (Total phenols, Terpenoids and Flavonoids) contents. Addition of compost (30 t/ha) and in combination with lime (2 t/ha) reduced post-cropping soil Pb concentration and accumulation in plant. Biomass accumulation was reduc.. Read More»
