Combining nitrogen and sulphur together increases nitrogen use efficiency so means more for your money with less wastage
Are you looking for information on arable crop nutrition? Start by choosing your crop.
Grain sampling has been around for a long time, but it’s not been used as part of a sampling routine on a lot of farms. Whilst grain analysis is a ‘look back’ on the season that’s complete that doesn’t mean hindsight can’t be a useful tool.
Knowing which nutrients were low, or even deficient, can help us alter the nutrient strategy for next season – improving overall nutrient efficiency. Having this data can also confirm what we were doing was right too, helping show you’re already working at optimum nutrient levels – this is also useful to know!
Sulphur is a good example of how to utilise the results you get from the analysis of the grain. An N:S ratio of below 17:1 is the target for wheat; if the ratio exceeds this it is an indication that there wasn’t enough sulphur available to the crop when it required it.
It’s not just the major nutrients that are useful, micronutrients are also measured in grain analysis and are, again, a good way to see whether they were at sufficient levels throughout the season. When we team grain analysis with soil analysis too, we can start to build a picture of the nutrient status of the farm and look at ways to mitigate risks or increase efficiencies where we can.
