Improving Nitrogen fertiliser Use Efficiency (NfUE) will be one of the most important ways in which UK growers can improve their business productivity in the future.
The single most important decision you can make to maximise your NfUE lies in the type of fertiliser you choose in the first place, says CF Fertilisers’ head agronomy Dr. Sajjad Awan. Whilst good management can help finetune the effectiveness of your applications, start with the wrong Nitrogen source and you’ll be locked into lower levels of NfUE with little you can do to lift it, he says.
“NfUE is essentially a measure of how much of the Nitrogen applied ends up in the crop. “In simple terms, if you apply 100kg N/ha and only 50kg N/ha is taken up by your crop, you will have an NfUE of 50% and half of the N you have paid for has gone somewhere other than into your crops as intended “Improving NfUE benefits your crop, your pocket and the wider environment.
Whether you are looking at it from the perspective of clean air, reducing your carbon footprint or increasing production efficiency, loss of N from the cropping system is a major problem.”
