Exchange in soil of Ammonium Nitrogen
Sep 29, 2016

Ammonium Nitrogen exist in NH4+ cation form which can be absorbed by plant roots easily.

  • NH4+ easy sorbed and bond securely with soil clays so not easy leaching.

  • NH4+ in soil can occur nitrification convert to NO3- and leach.

  • Can release ammonia to atmosphere in alkaline environment.

  • High concentrations can poison crops, especially young plants.

  • Too much absorbed of  Ammonium Nitrogen will inhibited the absorption of Ca, Mg and K.

  • Can not used for greenhouse vegetables.
