Copper, Zinc and nitrogen required for maximum grain yield of wheat following clover ley grown on sand 15 -30 cm) over orange brown sandy clay at Newdegate demonstration farm.
The addition of copper and zinc fertiliser applied Cu was applied in 1953.
!953 experiment a Cu & Zn experiment on oats.
In 1959 Cu and Zn reapllied on half plots.
Zn applied in 1953 had the same grain yield as Cu & Zn applied in 1959
Residual value of previous applied Cu & Zn were good
No further response of oats to second addition of Cu and or Zn after 6 years.
