IB® Nitrogen isobutylidene-diurea 31-0-0
|
Isobutylidene-diurea (IB) is a slow-release nitrogen. It can be found in products designed for use in turf, landscape, horticulture, land reclamation and forestry.
Since its release rate depends on particle size, IB has four uniform sizes: Greens-Grade SGN 85, Midsize SGN 145, Coarse SGN 250 and Extra-coarse SGN 400 (not recommended for turf). The smaller the particle, the shorter the longevity of IB.
