•Sub-millimolar urea effectively improves NH4+-inhibited plant/root growth of different species. Ammonium and nitrate are major soil inorganic-nitrogen sources for plant growth, but many species cultivated with even low millimolar NH4+ as a sole N form display a growth retardation. To date, critical...
