Waite Permanent Rotation Trial

History: rotation phase for each plot from 1925 to 1993.\nGrain yield: for each plot from 1925 to 1993.\nTotal dry matter: for each plot from 1925 to 1991.\nPasture cuts: for each plot from 1950 to 1991.\nPasture composition: for each plot from 1950 to 1991.\nMonthly climate data: from 1925 to 1993.\nSoil carbon data: measured total organic carbon (by combustion) and size fractions (by MIR-PLSR prediction) and delta 14C values for select plots for 1963, 1973, 1983 and 1993 for each of 0-10 cm and 10-22.5 cm depths.\nLineage: The data were collated by Jonathan Sanderman, CSIRO Agriculture flagship, from a number of sources. No custodian exists for data from this historic trial.\n\nNew measurements were made on archived soil samples by Jonathan Sanderman (CSIRO).\nPasture yield and composition were entered by Andrew Moore (CSIRO) from hard-copy experimental files.\nCrop yield data were collated by Heather Keith (Waite Agricultural Research Institute).\n\nUsers are directed to the following publications for further information:\nGrace, P.R., Oades, J.M., Keith, H., Hancock, T.W. 1995 Trends in wheat yields and soil organic carbon in the Permanent Rotation Trial at the Waite Agricultural Research Institute, South Australia doi:10.1071/EA9950857\nMoore, A.D., Grace, P.R. 1998 Effects of annual pasture composition on subsequent wheat yields in the Waite Permanent Rotation Trial,\nSouth Australia \ndoi:10.1071/EA97077
