Abstract :The aim of this study is to investigate the effects of different humic acid and phosphorus levels on corn plant insert ignore into journalissuearticles values( Zea mays L.); growth and P availability in a calcareous soil. Four levels of P insert ignore into journalissuearticles values(0, 20, 40, 80 mgkg-1); and 3 levels of humic acid insert ignore into journalissuearticles values(0, 250, 500 mgkg-1); were used in the experiment. The results showed that the dry weight, plant P concentration, P uptake and residual available P amount increased with humic acid applications, and that the effect of humic acid on the above parameters combined with P fertilisation was higher than that of humic acid alone.
