Effect of flyash on micronutrients uptake by plants grown on an acid soil

A pot culture study was conducted to evaluate the effect of flyash (0, 33, 66 and 100 g kg⁻¹ soil) and lime (0, 1/3, 2/3 and 1.0 L.R.) on micronutrient uptake by Sudan grass (Sorghum sudanense) and oats (Avena sativa) grown on an acid soil and micronutrients availability in soil. All levels of flyash and lime significantly increased the pH, decreased the availability of micronutrients in soil, and also significantly decreased the micronutrients' uptake by both the crops. Results indicate that flyash is as effective as lime to reduce the micronutrients toxicity to the plants grown on an acid soil. It indicates that flyash is a feasible alternative to lime for treating acid soil.
