Nurihoi kompleksi

Nurihoi kompleksi, nurihoesgt, ki dar tarkibi khud 2—3 moddai gizoii baroi rastani muhim (N, R₂O_b, K₂0) dorand. Ba tarkibi onho mikroelementhoi V, Mn, Si, Zn, Mo va Gg-ro niz dokhil kardan mumkin ast. Nurihoi kompleksii fosforu kaliydor, nit­rogenu fosfordor, nitrogenu kaliydor (dutarkiba) va nitrogenu fos­foru kaliydor (setarkiba) istehsol mekunand. Nurihoi kompleksi vobasta ba tarzi istehsol murakkab, murakkabu omekhta va omekhta meshavand.

Nurihoi kompleksii murakkabro dar natijai tasiri baynihamdigarii am­miak, kislotahoi nitratu fosfat, fosforitho, appatitqo, namakhoi tabiii kaliy va gayra dar holati dona-dona hosil mekunand. Ba Nurihoi kompleksii murakkab ammofos (56—64% moddai gizoi dorad), diammofos (71—74%), nitrofos (38%), selitrai kaliy (57%), nitroammofoska (50—54%), nitrofoska (36%⁽) va gayra, inchunip nurihoi moe, metafosfati kaliy, polifosfati ammoniy va gayra mavsuband.

Nurihoi kompleksii murakkabu omekhtaro bo rohi ba ham omekhtani nurihoi tayyor va bo kislotahoi sulfat, nitrat va ammiak yo ammiakatho kor kardani onho hosil mekunand. Nurihoi kompleksii murakkabu omekhta to 58% moddai gizoi dorand.

Nurihoi kompleksii omekhtaro mamulan ba tavri mekhaniki omekhtani nurihoi tayyor (asosan superfoofatro bo nu­rihoi nitrogendor va khloridi ka­liy) hosil mekunand. Selitra va digar nurihoi ammiakiro bo termofosfatho, khokistar va digar nurihoi ishqornok, inchunin karbamid omekhtan mumkin nest, zero nitrogen dar in mavrid nobud meshavad. Hangomi tayyor namudani Nurihoi kompleksi tanosubi omekhtahoro az rui khususiyathoi biologii ziroat va khosiyati khok muqarrar me­kunand.

Nurihoi kompleksiro baroi hama guna ziroat istifoda mebarand. Nurihoi kompleksii murak­kabro pesh az hama baroi ziroati tekhniki (pakhta, lablabui qand va gayra) ba kor mebarand.
