Progress of New Ireland Fertilizer Trials 1964 to 1970.

Abstract

Trials on the yellow-brown clay -loam soils of the east coast of New Ireland continued to show responses to potassium fertilizer. The previous recommendation of a biennial application of 5 lb of potassium chloride broadcast evenly over a circle about 20 ft in diameter around the base of the palm as giving the greatest economic response was confirmed.
