|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | 6 |
| 1 | Nitrogen fertiliser solution | Product obtained chemically and by dissolution in water, in a form stable at atmospheric pressure, without addition of organic nutrients of animal or vegetable origin | 15 % N Nitrogen expressed as total nitrogen or, if there is only one form, nitric nitrogen or ammoniacal nitrogen or ureic nitrogen Maximum biuret content: ureic N × 0,026 | Total nitrogen and, for any form that amounts to not less than 1 %, nitric nitrogen, ammoniacal nitrogen and/or ureic nitrogen If the biuret content is less than 0,2 %, the words ‘low in biuret’ may be added | |
| 2 | Urea Ammonium nitrate fertiliser solution | Product obtained chemically and by dissolution in water, containing ammonium nitrate and urea | 26 % N Nitrogen expressed as total nitrogen, where the ureic nitrogen accounts for about half of the nitrogen present Maximum biuret content: 0,5 % | Total nitrogen Nitric nitrogen, ammoniacal nitrogen and ureic nitrogen If the biuret content is less than 0,2 %, the words ‘low in biuret’ may be added | |
| 3 | Calcium nitrate solution | Product obtained by dissolving calcium nitrate in water | 8 % N Nitrogen expressed as nitrogen in nitric form with a maximum 1 % nitrogen as ammonia Calcium expressed as water soluble CaO | The type designation may be followed, as appropriate, by one of the following indications:
| Total nitrogen Water soluble calcium oxide for the uses stipulated in column 5 Optionally:

| 6 | Nitrogen fertiliser solution with urea formaldehyde | Product obtained chemically or by dissolution in water of urea formaldehyde and a nitrogenous fertiliser from list A-1 in this regulation, excluding products 3(a), 3(b), and 5 | 18 % N expressed as total nitrogen At least one third of the declared total nitrogen content must derive from urea formaldehyde Maximum biuret content: (ureic N + urea formaldehyde N) × 0,026 | Total nitrogen For each form amounting to at least 1 %:
Nitrogen from urea formaldehyde | |
| 7 | Nitrogen fertiliser suspension with urea formaldehyde | Product obtained chemically or by suspension in water of urea formaldehyde and a nitrogenous fertiliser from list A-1 in this regulation, excluding products 3(a), 3(b), and 5 | 18 % N expressed as total nitrogen At least one third of the declared total nitrogen content must derive from urea formaldehyde of which at least three fifths has to be soluble in hot water Maximum biuret content: (ureic N + urea formaldehyde N) × 0,026 | Total nitrogen For each form amounting to at least 1 %
Nitrogen from urea formaldehyde Nitrogen from urea formaldehyde that is soluble in cold water Nitrogen from urea formaldehyde that is only soluble in hot water |
