Nitrat og ammonium

Ammoniumnitrat er et viktig nitrogengjødsel. Nitrogenet kan opptas fullstendig av plantene.Det består av like deler ammonium og nitrat.Det inneholder 34% nitrogen.. Verdensproduksjonen var i 2012 på 47 millioner tonn (16 millioner tonn nitrogen) Ammonium er nemlig længere tid i rodzonen end nitrat, fordi det klistrer bedre jorden og derfor ikke så let bliver vasket ud. Vi ved desværre alt for lidt om hvornår og hvorfor nordmannsgran foretrækker nitrat eller ammonium, men det er et område, som vi ud fra krav om en effektiv gødskning og miljøhensyn ønsker at undersøge nærmere på Skov & Landskab

Tas opp av røttene som uorganisk nitrat (NO 3-), ammonium (NH 4 + / NH 3), urea eller fra organiske N-kilder f.eks. aminosyrer.Plantene vokser vanligvis best hvis begge nitrogenformene nitrat og ammonium er tilstede samtidig, bortsett fra surjordsplanter og ris som bruker ammonium som N-kilde og nitrat) og CO 2 som kan være begrensende og som krever godt dimensjonerte og drevne rensesystem. Ammoniakk kjemi og enheter for konsentrasjon . Ammoniakk foreligger i vann i en likevekt av en gass (ammoniakk-gass) og et ion, ammonium. Ammoniakk-gass er i overvekt den giftigste formen for fisk, og det er denne v Nitrater er fellesbetegnelse for saltene av salpetersyre (HNO3) og dens estere. Saltene fremstilles ved å løse metaller, metalloksider, -hydroksider eller -karbonater i salpetersyre. Ved oppvarming spaltes de tunge metallenes nitrater i metalloksid, evt. metall, nitrogendioksid, NO2, og oksygen. Nitrationet NO3 - er plant og isolelektronisk med karbonationet Ammonium (NH 4 +) er den mineralske formen som vanligvis dominerer i organisk avfall, men avhengig av behandlingsmetode kan mineralsk nitrogen også finnes som nitrat (NO 3-). Ved varedeklarasjon av organisk gjødsel er det krav om å oppgi innholdet av både totalnitrogen og mineralsk nitrogen (ammonium-N + nitrat-N)

  1. Ammonium-ionet (NH 4 +) er et fleratomig kation, som har molekylvekten 18,04 g/mol. Ionet dannes når ammoniakk reagerer med en syre, for eksempel ved reaksjon med vann (som her fungerer som en svak syre) under dannelse av ammoniakkvann (salmiakk).. Som den kanskje viktigste fleratomige, positivt ladde ion opptrer ammonium i salter på en tilsvarende måte som positive metallioner (for.
