Ammonium Nitrate or urea in a grassland situation

Choosing urea may save a little money upfront, but could reduce forage stocks as well as productivity and profitability for grassland farmers.

There is a good reason AN fertiliser from CF Fertilisers (Nitram®) has been the market leading Nitrogen fertiliser for British grassland farmers for more than 50 years. It is British made, lower carbon and has the same high quality every year.

Replicated trial work at Reaseheath College over 3 years have shown that AN (Nitram) delivers more than urea with increased yield of silage and grazing grass in spring and early summer.


In 10 out of 10 independent replicated trials, Nitram treated grass for silage had higher crude protein contents (CP%) compared to urea, by an average of 1.5%.

“Nitram raises silage grass CP%, regardless of soil type, location, and year”


Using Nitram in favour of the farm’s usual urea produced a 21% increase in grass silage in a trial at J. and S. A. Lancaster’s Paradise Farm in Horton, Lancashire.

 “Getting the most out of our grassland is absolutely key and we’ve learned a lot in recent years about managing this better, but there are always new techniques to learn and different thinking to consider.”

Nitram is the best option for the British maritime climate as there is a lower risk of N loss to atmosphere as ammonia.

Urea needs significant rainfall after application to avoid losing ammonia – and chances of getting enough are slim. Without the required rainfall, up to 50% of urea Nitrogen can be lost.
