Abstract

The scarcity of phosphorus (P) restricts crop growth due to reduced P uptake in acidic soil. Due to significant variations in soil pH in acidic Ultisol, it is still unclear how such variations would affect P uptake efficiency by maize plants. Thus, under different pH (3.75, 4.0, 4.5, 5.0 and 5.5) conditions, this study investigated the growth and P uptake efficiency during the growth of maize plants as influenced by the distribution of P species in Ultisols. Our results showed that increased soil acidity had a negative impact on plant height, dry matter yield (shoots and roots biomass), and chlorophyll content of maize plants. Also, the P uptake efficiency increased with decreased soil acidity, and the critical value for P uptake efficiency was pH 5.00. Generally, as soil pH was increased, soil available P decreased significantly and was consistent with higher uptake of available P by the plant and variations in different P species including those bound to iron, aluminum, and calcium.
