Fertilizer Response with Coconuts in Coastal Papua.

Abstract

A trial on a relatively old stand of coconuts on the south-east coast of Papua gave good responses to potassium despite a high magnesium/potassium soil ratio. The soil, which was representative of some of the coconut-growing areas of Papua, was a deep alluvial sandy loam. A surface clay-silt layer overlies the sandy loam in some cases and this layer is especially high in magnesium.
