Nutrient responses by white clover on a humic gley soil at Currumbin, South-East Queensland

Abstract

The field nutrient requirements for white clover (Trifolium repens cv. Ladino) establishment and growth were examined on a humic gley soil at Currumbin, routh-east coastal Queensland. Nutrient treatments applied in a t x 26 factorial design were lime, phosphorus potassium, sulphur and molybdenum plus a composite treatment of copper, zinc, boron, manganese and magnesium. Dry matter yield and nitrogen and phosphorus contents of white clover and weeds \Vere recorded from April 1969 to January 1970. Lime application gave the highest dry matter response but the difference between 2·5 and 5·0 t ha-1 disappeared with time. It was concluded that lime was the principal requirement for white clover establishment on this soil.
