Abstract: Releases of manganese and iron ions from an albic soil （Albic-Udic Luvisol）, a yellow-red soil （Hap-Udic Ferrisol） and a yellow-brown soil （Arp-Udic Luvisol） induced by calcium salt addition and their bioavailability to pepper （Capsicum frutescens L.） were studied in a pot experiment. Addition of Ca（NO3）2 decreased soil pH and increased both exchangeable and DTPA （diethylenetriamine pentaacetic acid）-extractable Mn and Fe in soils. Meanwhile, total Mn accumulation in the shoots of Capsicum frute... More
