Abstract

Soil and plant samples were obtained from a field experiment in which different levels of ?, ?, K, and Ca were combined in a 34 factorial arrangement. The pattern of ? movement in topsoil (0 - 15 cm) was measured over a period of three years and related to rainfall and crop removal. The extent of ? drainage to subsoil horizons over two seasons was determined and the effects of ?, ?, K, and Ca levels on ? movement to lower horizons assessed.
