Özet:

This research was carried out to determine the effects of lime, organic and inorganic (waste sludge- WS zeolite- ZEO polyacrylamide-PAM) based soil conditioner applications on phosphorus nutrition of corn plant. In the research carried out under greenhouse conditions, lime was applied in three different doses and the conditioner were applied in four different doses. The research soil has a clayey texture, initially strongly acidic reaction (pH, 5.2) and moderate organic matter content. Soils were incubated for 56 days in the factorial design study. After incubation, periods corn plants were grown in pots. It has been determined that the applications made caused a change in the P nutrition of the corn plant grown depending on the variety, application level and pH value of the soil. It was determined that the conditioners were ranked as WS>ZEO> PAM in terms of their effects on the P nutrition of the maize plant. WS was found to be effective at different pH levels, whereas PAM and Zeolite were effective only at neutral pH levels. The 6.0% dose of WS was determined as the most effective application for P nutrition in slightly acid soil.
