[QUOTE="Farmer Roy, post: 8484670, member: 71668"] 1 unit here is one kg 100kg / ha of urea is 46 units We will apply large amounts of urea / N at planting, but it is always separated from the seed, either below or beside the seed row. Highest down the spout at very narrow rows ( 4.5 inches ) that I’ve heard of for wheat is 100 kg urea or 46 units of N. On our more normal, wider row spacings of 250 - 333 mm spacings, then more like just 10 - 20 kg / units of N Quite common for us to pre - sow urea / N months prior to planting, but we have clay soils with high OM levels, so get very little leaching or movement of N through the soil profile with our row crops on 1 metre spacings, then side dressing N after planting / emergence is always an option as well. personally, I’d be very hesitant to put much N in contact with the seed [/QUOTE]
