Effects of sewage sludge at different pH levels on Ipomoea aquatica

2012

E06118

An experiment was conducted to study the effects of sewage sludge on the response of Ipomoea aquatica to plant nutrients and heavy metals in soil at different soil pH. An incubation study was done for the selection of four individual pH levels, viz., 4.7, 5.7, 6.6 and 7.8 to be used for the plant culture experiment. Yield of Ipomoea aquatica and concentration and uptake of N, P, K, Ca, Mg, Cd, Cu, Fe, Mn and Zn in the plant were evaluated. Application of sewage sludge in soil increased the concentration and uptake of the elements in Ipomoea. Slightly acidic to slightly alkaline pH was found to be better for amendment of soil with sewage sludge.
