Itandukaniro hagati ya dap na npk ifumbire

Itandukaniro ryingenzi hagati ya Dap na NPK nuko ifumbire ya Dap idafitepotasiyumuMugihe ifumbire ya NPK irimo potasiyumu.

Ifumbire ya Dap ni iki?

Ifumbire ya Dap ni inkomoko ya azote na fosifona ifite imikoreshereze yagutse. Ibice byingenzi muri iyi gerdilizer ni diammonium fosfatiri ifite imiti (NH4) 2hpo4. Byongeye kandi, izina rya IUPAC ryibi bigo ni diammonium hydrogen fosphate. Kandi ni ammonium ya ammonium.

Mubikorwa byumusaruro wiyifungiye, turasubiza aside fosporic hamwe na ammonia, bigize agace gashyushye noneho karangwa no kugotwa kugirango tubone ifumbire dushobora gukoresha mumurima. Byongeye kandi, dukwiye gukomeza imyitwarire yagenzuwe kuko reaction ikoresha aside sulfuric, ikaba ari bibi gukora. Kubwibyo, icyiciro cyintungamubiri gisanzwe cyiyi nfura ni 18-46-0. Ibi bivuze, ifite azote na fosito muri getio ya 18:46, ariko ntabwo ifite potasiyumu.

Mubisanzwe, dukeneye toni zigera kuri 1.5 kugeza kuri 2 za fosifate, toni 0,4 za sulfuru kugirango zishonge urutare, na toni 0...2 za Ammoni yatangajwe na Dap. Byongeye kandi, phi yiyi ngingo ni 7.5 kugeza 8.0. Kubwibyo, niba twongeyeho iri genzura kubutaka, birashobora guteza PH ya alkaline hafi yifumbire ifumbire ishonga mumazi yubutaka; Gutyo, umukoresha agomba kwirinda kongeramo ingano yifumbire.

Ifumbire ya NPK ni iki?

Ifumbire ya NPK ni ifumbire eshatu zigize akamaro zingirakamaro mubikorwa byubuhinzi. Iyi fumbire ikora nkisoko ya azote, fosishorus na potasiyumu. Kubwibyo, nisoko yingenzi yintungamubiri eshatu zibanze zisaba igihingwa gisaba gukura, iterambere n'imikorere ikwiye. Izina ryibi bintu naryo ryerekana intungamubiri ishobora gutanga.

Urutonde rwa NPK ni uguhuza imibare bitanga igipimo hagati ya azote, fosifori na postisipiyuri yatanzwe niyi fumbire. Ni ihuriro ryimibare itatu, itandukanijwe nimirongo ibiri. Kurugero, 10-10-10 byerekana ko ifumbire itanga 10% ya buri kintu. Ngaho, umubare wambere uvuga ijanisha rya azote (n%), umubare wa kabiri ni uzira ijanisha rya fosifori (muburyo bwa p2o5%), naho icya gatatu ni ijanisha rya potasiyumu (k2o%).
