Urea 46% Fertilizer

Gandi Chemical Solutions supplies Urea 46% Fertilizer (CAS 57-13-6) to blenders, distributors and commercial growers. It is supplied as agricultural (granular and prilled) grade. Packaging: 50kg bags, 1000kg bulk bags, bulk. Priced by quotation, with a current safety data sheet on every consignment.

Urea 46% Fertilizer carries more nitrogen per tonne than any other solid fertilizer, which is why it moves in the volumes it does. GCS supplies it as granular urea for mechanical spreading over wide bouts and as prilled urea for hand application, blending and dissolving into solution. The two are not interchangeable in a spreader. Nitrogen is 46% minimum, biuret is held at or below 1.0% and moisture at or below 0.5%, with CAS 57-13-6 and formula CO(NH2)2. It is the standard nitrogen top dressing on maize, wheat, rice and pasture, and the feedstock behind most liquid nitrogen solutions. The one operating caution is placement: surface-applied urea loses nitrogen to the air, so it needs incorporating, irrigating in, or applying ahead of rain. Supplied in 50 kg bags, one-tonne bulk bags or loose in bulk.

Where urea 46% fertilizer is used

Urea carries more nitrogen per tonne than any other solid fertilizer, which is why it moves in the volumes it does. The catch is that it only stays in the field if it gets below the surface soon after spreading.

• Nitrogen top dressing on maize, wheat, rice and other cereals
• Pasture and fodder nitrogen through the growing season
• Feedstock for liquid nitrogen solutions and blended fertilizers
• Nitrogen source in plantation and horticultural feeding programmes
• Industrial and technical uses where a high-purity nitrogen source is needed

Key features

• Agricultural (granular and prilled) grade. White free-flowing granules or prills.
• CAS 57-13-6, CO(NH2)2.
• Also ordered as Urea, Carbamide, Carbonyldiamide.
• Supplied in 50kg bags, 1000kg bulk bags, bulk, with larger units quoted on request.

Specification and grade

Supplied as granular or prilled urea at 46% nitrogen minimum, CAS 57-13-6, formula CO(NH2)2, molecular weight 60.06 g/mol. Biuret is held at or below 1.0% and moisture at or below 0.5%. Granular urea runs 2-4 mm and suits mechanical spreading over wide bouts; prilled urea is smaller and more uniform, and is the usual choice for hand application, for blending, and for dissolving into solution. Both are white, free-flowing and fully water-soluble.

Handling and storage

Non-hazardous in normal supply and safe to handle with ordinary care, but strongly hygroscopic: an opened bag left in humid air will cake solid. Store sealed, dry and off the floor, and keep it away from acids and from strong oxidisers. Dust from broken granules is an irritant; a mask and goggles are worth having on the spreader.

Packaging and supply

Packed in 50 kg polypropylene bags, one-tonne bulk bags, or shipped loose in bulk. Say whether you need granular or prilled, and whether it is going through a spreader, a blender or a solution tank. The three do not want the same product. Bulk pricing applies at full-load volumes.
