<i>SHORT COMMUNICATION</i>: Lime-amended acid soil has elevated pH 30 years later

Abstract

Lime-amended acid soil (a single application in 1963 at rates of 4.5 and 6.7 t ha −1 ) at Scott, Saskatchewan had pH of 0.5 and 1.1 units higher, respectively, than unlimed soil, when measured more than 30 yr later in 1994. However, no differences in soil-available phosphorus levels and crop yield were detected. Key words: Soil acidity, lime, phosphorus, Brassica rapa L., Triticum aestivum L.
