Abstract

Project title: Evaluation of existing diagnostic procedures for the recommendation of trace element fertilizers.

Aim: To compare the accuracy and reliability of a range of tissue and soil tests being variously promoted for use to farmers for the diagnosis and prognosis of zinc and copper deficiencies in wheat crops on Western Australian farms.

Trial 87N23

Nitrogen rates on the main copper plots of the long term copper residual trial at Newdegate Research Station.

Location: Newdegate Research Station

To determine the effects of rates of nitrogen on the copper status of plants.

Trial 87LG33

Effects of rates of nitrogen on the copper and zinc concentration and grain yield of wheat plants grown on old land (previous copper, zinc history known).

Location: Lake Grace

To examine the possibility of rates of nitrogen inducing copper and zinc deficiency in wheat.

Trial 87LG34

Effects of rates of nitrogen on the copper and zinc concentration and gain yield of wheat plants grown on old land.

Location: Newdegate.

To examine the possibility of rates of nitrogen inducing copper and zinc deficiency in wheat.

Trial 86LG34

Residual value of copper, zinc and sulphur with high analysis nitrogen and phosphorus fertilizer under continuous cropping situation.

Location: South Newdegate.

To determine the decline in effectiveness of copper, zinc and sulphur on this soil types using DAP.

Trial 67E8, 67E9

Effects of rates on nitrogen on copper concentrations, dry matter production and grain yield of wheat grown on a residual copper trial.

Location: Esperance Down Research Station

The trial was originally designed to measure the residual effectiveness of rates of copper fertilizer drilled in 1967.

Trial 86E44, 87JE21

The effects of rates of nitrogen on the copper and zinc status of wheat plants and grain production.

Location: Esperance Down Research Station and West River

To examine the possibility of rates of nitrogen inducing copper and zinc deficiency in wheat.

Trial 87JE34

The effects of rates of nitrogen on the zinc status and of wheat plants grown on newland.

Location: Old Ongerup Road W. River

To measure the effects of DAP and high nitrogen rates on the severity of zinc deficiency of wheat grown on this newland site.

Trial 87JE22

The effects of rates of nitrogen on the copper and zince status of wheat plants and grain production.

Location: West River.

To examine the possibility of rates of nitrogen inducing copper and zinc deficiency in wheat.

Trial 87E30

The effects of rates of phosphorus and nitrogen on the copper and zinc status of wheat plants and grain production.

Location: Esperance Down Research Station.

To examine the possibility of rates of nitrogen and phosphorus inducing copper and zinc deficiency in wheat.

Trial 87E44

Deep placement of manganese for lupins.

Location: Esperance Downs Research Station.

To determine the effect of deep placement of manganese and foliar applied manganese on lupin plant tissue levels, split seed incidence and grain yield.
