Copper, Zinc and nitrogen required for maximum grain yield of wheat following clover ley at Dandaragan.
The addition of copper and zinc fertiliser applied in 1953 was adequate in 1959.
Copper was applied as Cu ore
Further additions in combination or alone had no further effect on grain yileld
6 years of clover ley; Addition N as ammonia sulphate (112 kg/ha) reduced seedling stands & reduced grain yield.
Anticipated a response to Cu
