Investigation of zinc application options locations

To assess a range of application methods for zinc including seed dressing, soil and foliar sprays and zinc with super fertiliser.

Key messages
  • Early zinc uptake can be increased when zinc is applied as soil spray, seed coat or granular fertiliser but this does not necessarily increase yield.
  • Products differ markedly in price per kg of elemental zinc so carefully consider your choice to get best value for money.
  • Make sure choice of application method fits your farming system: for example if you are no-till then soil spray inefficient as not worked into root zone, foliar spray too late if you have zinc deficient soil as yield losses will already have occurred.
  • Some products have short term benefits (seed coats and foliar sprays) and some longer term benefits.
