Itandukaniro Hagati ya DAP na NPK Ifumbire

Itandukaniro ryibanze hagati yifumbire ya DAP na NPK nuko ifumbire ya DAP idafitepotasiyumumugihe ifumbire ya NPK irimo potasiyumu nayo.

Ifumbire ya DAP ni iki?

Ifumbire ya DAP ni isoko ya azote na fosifori ikoreshwa cyane mubikorwa byubuhinzi.Ikintu cyingenzi muri iyi fumbire ni diammonium fosifate ifite formulaire yimiti (NH4) 2HPO4.Byongeye kandi, izina rya IUPAC ryuru ruganda ni diammonium hydrogen fosifate.Kandi ni amazi ya elegitoronike ya amonium fosifate.

Mubikorwa byo gukora iyi fumbire, twakira aside fosifori hamwe na ammonia, ikora ibishishwa bishyushye noneho bigakonjeshwa, bigasya kandi bikayungurura kugirango tubone ifumbire dushobora gukoresha mumurima.Byongeye kandi, dukwiye gukomeza kubyitwaramo mugihe cyagenzuwe kuko reaction ikoresha aside sulfurike, ishobora guteza akaga.Kubwibyo, intungamubiri zisanzwe ziyi fumbire ni 18-46-0.Ibi bivuze, ifite azote na fosifori ku kigereranyo cya 18:46, ariko ntigira potasiyumu.

Mubisanzwe, dukeneye hafi toni 1.5 kugeza kuri 2 zurutare rwa fosifate, toni 0.4 za sulfure (S) kugirango zishongeshe urutare, na toni 0.2 za ammonia kugirango dukore DAP.Byongeye kandi, pH yiyi ngingo ni 7.5 kugeza 8.0.Kubwibyo, niba twongeyeho iyi fumbire mubutaka, irashobora gukora alkaline pH ikikije granules yifumbire ishonga mumazi yubutaka;bityo uyikoresha agomba kwirinda kongeramo umubare munini wiyi fumbire.

Ifumbire ya NPK ni iki?

Ifumbire ya NPK ni ifumbire mvaruganda itatu ifite akamaro kanini mubikorwa byubuhinzi.Iyi fumbire ikora nkisoko ya azote, fosifore na potasiyumu.Kubwibyo, nisoko yingenzi yintungamubiri zose uko ari eshatu igihingwa gisaba kugirango gikure, gikure kandi gikore neza.Izina ryibi bintu naryo ryerekana intungamubiri zishobora gutanga.

Igipimo cya NPK ni ihuriro ryimibare itanga ikigereranyo kiri hagati ya azote, fosifori na potasiyumu itangwa nifumbire.Ni ihuriro ryimibare itatu, itandukanijwe nimirongo ibiri.Kurugero, 10-10-10 byerekana ko ifumbire itanga 10% ya buri ntungamubiri.Hano, umubare wambere werekana ijanisha rya azote (N%), umubare wa kabiri ni uwijanisha rya fosifori (muburyo bwa P2O5%), naho iya gatatu ni iyijanisha rya potasiyumu (K2O%).
