Understanding zinc reactions in vertisols to predict zinc responses by wheat locations
Aims

To improve predictability of growth responses to zinc from soil analysis.

Key messages
  • 14 vertisols were sampled and analysed in the laboratory, and were sown to wheat in the glasshouse.
  • DTPA-extractable zinc, zinc desorption and diffusion rates, and buffer power were measured.
  • DTPA-extractable zinc and zinc desorption rate accounted for 80% of the variation in relative dry matter yield of wheat at anthesis.
  • Inclusion of buffer power increased this to 92% of the variance in relative dry matter yield.
  • These measure provide a better indicaiotn of the likely responsiveness of soils than the traditional single DTPA-extractable zinc.
