Zinc banded with NP fluid fertilisers under the seed row is effective locations

To explore the effectiveness of zinc when applied with fluid nitrogen and phosphorus fertiliser.

Key messages
  • Zinc in shoots at tillering was much higher in plants supplied with fluid phosphorus than with granular phosphorus.
  • Given that in both sets of treatments zinc was supplied as zinc chelate at quite a low rate (0.75 kg zinc/ha) in a fluid below the seed row (except in fluid treatments it was mixed with TGMAP) these results suggest that mixes of trace elements with NP fluid fertilisers may be a more effective technique for supplying trace elements to broad acre crops.
  • Conditions in both trials were not zinc deficient for wheat production so the absence of zinc in fertilisers at seeding had no impact on the productivity of either wheat at either site, or on their response to phosphorus fertilisers.
