Soil amendment with fly ash (FA) and combined supplementation with N2-fixing cyanobacteria masses as biofertilizer were done in field experiments with rice. Amendments with FA levels, 0, 0.5, 1.0, 2.0, 4.0, 8.0 and 10.0kg/m2, caused increase in growth and yield of rice up to 8.0kg/m2, monitored with several parameters. Pigment contents and enzyme activities of leaves were enhanced by FA, with the...
Fly ash (FA) from coal in Orissa (India) was used for amending soil at levels equivalent to 0, 1, 2.5, 5, 10 and 15 metric tons per ha in which, rice was grown and elemental residues of amended soil and plant parts were enumerated.
