Umehluko Phakathi Kwe-DAP kanye Nomanyolo we-NPK

Umehluko omkhulu phakathi komanyolo weDAP kanye neNPK ukuthi umanyolo weDAP awunayoi-potassiumkuyilapho umanyolo we-NPK uqukethe i-potassium futhi.

Yini i-DAP Fertilizer?

Umanyolo we-DAP uyimithombo ye-nitrogen ne-phosphorous esetshenziswa kabanzi ngezinhloso zezolimo.Ingxenye enkulu kulo manyolo i-diammonium phosphate enefomula yamakhemikhali (NH4)2HPO4.Ngaphezu kwalokho, igama le-IUPAC lale nhlanganisela i-diammonium hydrogen phosphate.Futhi iyi-ammonium phosphate encibilika emanzini.

Enqubweni yokukhiqiza lo manyolo, siphendula i-phosphoric acid ne-ammonia, eyenza i-slurry eshisayo bese ipholiswa, ihlungwe futhi ihlungwe ukuze sithole umanyolo esingawusebenzisa epulazini.Ngaphezu kwalokho, kufanele siqhubeke nokusabela ngaphansi kwezimo ezilawulwayo ngoba ukusabela kusebenzisa i-sulfuric acid, eyingozi ukuyiphatha.Ngakho-ke, izinga elijwayelekile lezakhi zalo manyolo ngu-18-46-0.Lokhu kusho ukuthi, ine-nitrogen ne-phosphorous ngesilinganiso esingu-18:46, kodwa ayinayo i-potassium.

Ngokuvamile, sidinga cishe amathani angu-1.5 kuya kwangu-2 etshe le-phosphate, amathani angu-0.4 esibabule (S) ukuze sihlakaze idwala, kanye namathani angu-0.2 e-ammonia ukuze kukhiqizwe i-DAP.Ngaphezu kwalokho, i-pH yale nto ingu-7.5 kuya ku-8.0.Ngakho-ke, uma sengeza lo manyolo emhlabathini, ungakha i-pH ye-alkaline ezungeze ama-granules omanyolo ancibilika emanzini enhlabathi;ngakho-ke umsebenzisi kufanele agweme ukwengeza inani eliphezulu lalo manyolo.

Yini Umanyolo we-NPK?

Ama-fertilizer e-NPK yizingxenye ezintathu zomanyolo eziwusizo kakhulu ngezinhloso zezolimo.Lo manyolo usebenza njengomthombo we-nitrogen, phosphorus ne-potassium.Ngakho-ke, iwumthombo obalulekile wazo zonke izakhi ezintathu eziyinhloko isitshalo esidinga ukukhula kwaso, ukukhula nokusebenza ngendlela efanele.Igama lalesi sithako liphinde liveze umsoco engasinikeza.

Isilinganiso se-NPK inhlanganisela yezinombolo enikeza isilinganiso phakathi kwenitrogen, i-phosphorus ne-potassium enikezwa yilo manyolo.Kuyinhlanganisela yezinombolo ezintathu, ezihlukaniswa ngamadeshi amabili.Isibonelo, i-10-10-10 ibonisa ukuthi umanyolo uhlinzeka ngo-10% wesakhi ngasinye.Lapho, inombolo yokuqala ibhekisela ephesentini le-nitrogen (N%), inombolo yesibili ngephesenti le-phosphorous (ngezinhlobo ze-P2O5%), kanti eyesithathu iphesenti le-potassium (K2O%).
