The agrochemical effectiveness of some phosphorus-nitrogen compounds with the direct P−N bond

Agrochemická úěinnost některých dusíkofosforečných sloučenin s přímou vazbou P−N

  • Published:
Biologia Plantarum

Abstract

Phosphorus-nitrogen compounds characterized by the direct P−N bond, represented by trimeric and tetrameric phosphorus nitridoamide—[PN(NH2)2]3–4, phosphorus oxytriamide—PO(NH2)3 and ammonium diamidophosphate—NH4PO2(NH2)2, were applied as fertilizers in a vessel experiment with barley and their agrochemical effectiveness was compared with that of ammonium phosphate—(NH4)2HPO4. The results obtained indicate that the above compounds are of nutritive value for plants.

Abstract

Dusíko-fosforečné sloučeniny charakterisované přímou vazbou P−N representované trimérním a tetramérním fosfornitridamidem—[PN(NH2)]3–4, fosforoxytriamidem—PO(NH2)3 a diamidofosforečnanem amonným—NH4PO2(NH2)2 byly aplikovány jako hnojiva v nádobovém pokusu u ječmene a porovnávány agrochemické účinnosti se středním fosforečnanem amonným—(NH4)2HPO4. Dosažené výsledky indikují, že uvedené sloučeniny se mohou příznivě uplatnit ve výživě rostlin.
