Notes:
Summary An assessment of the status of available micronutrients has been made in a long term field experiment on a fixed rotation of soybean-potato-wheat at the Ranchi Agricultural College, Kanke on acid soil. Results of eight years fertilizer applications with lime has resulted in reduction of available micronutrients whereas the FYM application with balanced dose of chemical fertilizers increased the available micronutrients of soil. The maximum loss of 1.0 Zn and 13.2 Fe kg/ha respectively were from the lime treated plots with balanced dose of fertilizers and the highest gain of 0.26 Zn, 1.08 Cu, 13.2 Fe and 54.0 Mn kg/ha respectively were recorded from the FYM treated plots with balanced dose of chemical fertilizers. Organic carbon was significantly positive correlated with av. Zn & Mn, whereas av. Mn significantly negative correlated with pH. Other relationship were found to be non significant.
