Are you sure you’re seeing nitrogen deficiency?
Don’t automatically assume that your crops are suffering from nitrogen deficiency. A lack of sulphur often has the same impact as nitrogen deficiency as the two nutrients work hand-in-hand. Whilst sulphur deficiency may be visible in the upper leaves of your crops, as nitrogen needs sulphur to work efficiently, you may see deficiency in lower leaves as well.
Make your nitrogen go further with a ready supply of sulphur
Take control of sulphur levels proactively to maximise nitrogen use efficiency. There is little point in spending more money on nitrogen if you haven’t spent any on sulphur.
How to secure consistent sulphur availability
A little and often approach to sulphur management is essential as sulphate is known to leach, in a similar way to nitrates.
