Molybdenum   residual for clover grown on orange brown  gravelly sand  (mallee scrub)  at Walebing locations
Aims

To determine the residual effectiveness of Mo fertiliser  for maximum clover ley grown on  orange brown gravelly sand countryl

Key messages

Experiment started in 1992 reddish brown sandy loam ; soil pH (CaCl2) of 5.7.

1992:

Small (15%)  response to limesand at 1.5 t/ha & to Mo application applied as sodium molybdate.

Nitrogen concentration of medic increased from 4.2 to 5% with Mo application @ 200g/ha, 1.5 & 3 t/ha limesand.

limesand with Mo did not increase yield or N content compared with 200 g of Na molybdate alone.

Critical Mo concentratin in clover tops appeared to be 0.09 mg/kg

Combination of lime sand (1.5 t/ha) and 200 g Na molybdate recommended: increased dry matter produced by 30% above the control.

3 t/ha limesand produced the same yield without Mo.
