Descriere produs
Ingrsamant de tip Uree cu 46 % azot (N) , este cel mai concentrat fertilizant simplu solid cu azot, aici acest element se alfa in forma amidica (NH2), cu evolutie foarte buna in sol, unde hidroliza este sustinuta de ureobacterii. Pe aceasta cale fizico-chimica, dar si microbiologica, rezerva de azot (N) detinuta se converteste in azot amoniacal (NH4+) si nitric (NO3–) care in stare solubila au un bun contact cu coloizii solului, solutia acestuia si radacinile plantelor. De aceea se apreciaza ca Ureea in sol are o buna evolutie, ceea ce ii confera o buna valorificare a potentialului fertilizant.
Ingrasamantul de tip Uree indeplineste indeplineste un rol esential in urmatoarele procese tehnologice:
In fertilizarea de primavara a graului;In hranirea si imbogatirea solului din cultura cartofului;La fertilizarea plantelor oleaginoase, cum este cultura de rapita, unde ureea se recomanda pentru aplicarea primei fractii de azot (la reluarea vegetatiei) si in strategia de maximizare a productiei, in preajma infloritului;ÃŽn lanul de porumb boabe, unde poate favoriza asimilarea nutrientilor.Pe termen lung, ureea mentine un pH neutru in sol, ceea ce satisface majoritatea plantelor in exigenta si cerintele fata de reactia solului.Caracteristicile fizico-chimice ale ingrasamantului tip Uree:
