Rising nitrogen fertiliser costs are squeezing profit margins for many UK arable and lives
Finding sustainable savings is crucial.
Legumes like clover and vetch naturally capture nitrogen from the air and fix it in your s
This 'legume nitrogen credit' can significantly reduce your need for costly synthetic N fe
It's the amount of nitrogen (N) that legumes add to your soil, available for your next cas
This N is stored in plant residues and root nodules, slowly releasing as they decompose.
Fixation rates vary by legume type, soil conditions, and management practices across the U
Specific fixation rates vary significantly by legume type and conditions.
First, estimate the total nitrogen fixed by your chosen legume cover crop or ley.
For example, a good stand of red clover might fix a significant amount of N.
Not all fixed N is available immediately. A credit factor (e.g., a certain percentage) estimates N availabl
So, fixed N * credit factor = N credit for your next crop.
If you have a certain area of red clover, your total nitrogen credit would be N/ha * area
This total N is what you effectively gain without buying synthetic fertiliser.
This N credit replaces a certain amount of urea (a specific N content), saving significant co
At a typical price for urea, this translates to a saving of a significant amount for your farm.

Red clover is excellent for deep rooting and high N fixation, suitable for longer leys.
White clover is perfect for grazing pastures due to its resilience and ability to withstan

Plan your rotation to follow legumes with high N-demanding crops like wheat or maize.
Soil testing helps you accurately gauge available N and adjust your fertiliser inputs acco
Legumes also improve soil structure, increase organic matter, and enhance biodiversity on
These benefits contribute to overall farm resilience and environmental sustainability.
Stop guessing how much nitrogen your legumes are providing. Get precise calculations.
This allows you to cut back on expensive inputs without risking your precious yields.
