Abstract

Pronalazak se odnosi na postupak proizvodnje tečnih složenih organomineralnih suspenzionih djubriva na bazi vodorastvornih reakcionih produkata uree i formaldehida kao disperznog medijuma i suspenzionog agensa, i odgovarajuće mineralne komponente nosioca hranljivog elementa kao što su: urea, amonijum-fosfat, sirovi fosfat i kalijum-hlorid. U tu svrhu se karbamid-formaldehidnom kondenzatu sa molskim odnosom urea-formaldehid 1:1,8-2,4 i sadržajem suve materije 45-55% (ref.) dodaje urea do potpunog rastvaranja, a u masenom odnosu 1:0,4-0,8. Dobiveni rastvor sadrži 60-70% suve materije, čijom aktivacijom u kiseloj sredini produkt prelazi u stanje tiksotropnog gela sposobnog da primi i 50-70% mineralne komponente nosioca hranljivog elementa, gradeći stabilnu N, NP ili NK suspenziju. Mešanjem ovih rastvora dobijaju se složene NPK organomineralna djubriva, koja pored djubrenja osnovnim elementima omogućuju i unošenje organske materije u zemljište, a ispoljavaju efekat usporenog dejstva, smanjenje gubitka azota, kao i njegovu bolju retenciju u zemljištu.
