P, Zn and Mn fluid and granular fertilisers: movement and availability locations
Aims

To compare the movement and potential availability of Mn, Zn and P when supplied as granular or fluid products in a calcareous and non-calcareous soil.

Key messages
  • Movement of water towards P fertiliser granules occurs and in calcareous soils this causes P to form a solid precipitate with calcium ions and prevents P moving away from where it is applied and reduces likely availability.
  • Manganese from fluid fertilisers moves further away from point of application compared to a granular source of Mn and was potentially more available.
  • Movement of zinc away from point of application was restricted regardless of the source and in both soils but fixation of zinc was less when the sources was fluid rather than granular.
