Data from more than 580 field experiments conducted in South Australia over the past 30 years have been re-examined to estimate extractable soil phosphorus (P) levels related to 90% maximum yield (C90) for 7 crop species (wheat, barley, oilseed rape,

Relations between the growth intervals in wheat and meteorological variables were defined from time-of-sowing field experiments. The major factors affecting the duration of each interval were the date of sowing, the day-degrees of maximum air tempera

The response of annual medic dominant pastures to residual and currently applied phosphorus was examined in twelve experiments in cereal areas of South Australia. The experimental sites had been sown in the previous year to wheat with nine rates of p

A number of phosphate fertilizers were tested as a source of phosphorus for wheat during three seasons (1967-1969) in the cereal growing areas of South Australia. The fertilizers were standard superphosphate, double superphosphate, calcium phosphate,

A useful method of analysing yield data from experiments comparing different methods and times of application of superphosphate is given. Responses by wheat at six sites in South Australia and two in Western Australia were analysed to compare the eff
