Nitrogen – Key to Yield and Productivity

Nitrogen is required by plants in large quantities and is essential for optimum growth, yield, product quality and also one of the largest input costs on a farm.

Profit margins directly relate to its careful management and, while too little application means yield and quality will be severely constrained reducing profit margins, also over or inaccurate application can result in lower productivity and losses to air and/or water, harming the environment.

CF have taken a leading role to help the industry to achieve high yield and product quality and maximise profit margins without compromising on the environment. To achieve this, we have initiated a large scale programme to set up Nitrogen fertiliser Use Efficiency trials.

Largest Set of NfUE Trials Ever Now Underway

Nitrogen fertiliser Use Efficiency (NfUE) shows farmers how well they are using their Nitrogen fertiliser. Sajjad Awan, CF Agronomist explains ‘for instance, if 100 kg N/ha is applied and 75 kg N/ha is removed in the harvested material then 25 kg N/ha is not utilised by the crop, the NfUE in this example is 75%. NfUE depends on several factors but some of the most important ones are the choice of variety, type of fertiliser used, timing and rate of application’

CF/Frontier NfUE Trials

Agriculture is facing both financial and environmental challenges but focusing on and improving NfUE will help address both.

 As National Crop Nutrition Technical Manager at Frontier I fully recognize the importance of improving how efficiently Nitrogen, and all nutrients, are taken up and utilized by crops.  This improvement clearly has a positive financial benefit for our farmers but equally also minimises their impact on the environment. 

I believe farmers are looking to make improvements so it will be interesting to see this year’s results after harvest, however I also acknowledge that more can and needs to be done to make gains in efficiency.  In most cases there will not be one single factor that makes significant improvement, instead it is more likely to come from a greater attention to detail throughout the whole process, akin to the ‘marginal gains’ approach often talked about in elite sport.

Agriculture faces several challenges going forward, both financial and environmental but what is great about focusing on and improving NfUE is that it addresses both of these at the same time.

CF/Agrii NfUE Trials

-

Agrii are really pleased to be working on, and supportive of, this important project.

Through Agrii’s “Green Horizons” initiative we are committed to leading the way in sustainable food production and supporting our customers in becoming more resilient in an increasingly uncertain world.

The initiative encompasses a wide range of ambitions, which are all structured around our five-point plan

Supporting the CF NFUE project fits very well into our strategic initiative as it will help farmers make the best use of applied fertiliser, as well as ensuring maximum crop usage while minimising losses, and therefore emissions.
