Aims

To investigate the effects of rates of initial and subsequent applications of zinc on pasture yields grown on gravelly forest gravel soil

Key messages

Rates nil to 5 kg Zn/ha applied in 1970. Results for 1977.

Zn applied in 1970 barely detectable although application of plain super at 250 kg/ha /yr since 1970 maintain Zn levels for near maximum yield of pasture..

The author indicated the following:  

Suggestion that results indicated need to reassess the Zn requirement of a wide on inherently Zn deficient soils. This is particularly so in the absence of Zn via the Zn impurities in super from traditional sources of rock phosphate. It maybe highly likely that some future date we may have to rely on low Zn containing Zn phosphates .  Unless more information is obtained in advanced there could be serious losses due to Zn deficiency some time in the future.
