Soil acidity is one of the major concerns in plant productivity in the world. Growth and yield of many crops are affected by soil acidity. The presence of various toxic elements such as Fe, Mn, soluble forms of Al alters the chemical properties of soil making it unsuitable for plant growth and productivity. One of the major constraints of acidic soil is aluminium toxicity. In the present study, soil was treated with 0mM, 10mM and 20mM AlCl3 respectively and maize seeds were inoculated in them. Rhizospheric soil was then estimated for parameters such as fluorescein di acetate (FDA) activity, alkaline phosphatase activity, nitrate reductase activity and glomalin activity. The results depicted that aluminium showed negative impact on all the estimated activities revealing that under aluminium stressed conditions various plant growth promoting activities of soil are diminished, which may be one of the possibilities of decreasing plant growth under aluminium stressed conditions.
