With combining over its time to mull over the 2013 yield maps. This year rather than look at the good ones, ignore the bad ones and then put them in a draw never to be seen again, consider how this data can be used to make changes that will improve next year‘s proﬁtability, is the advice from Charles Wright, Farmacy agronomist in the East Midlands.
Where poor areas can be identiﬁed this year compare these with the historical “field performance” – but remember that in such a difficult season it’s important not to jump to conclusions, he says.
“However, if historical performance has been poor and this has been born out again, why assume 2019 will be any different?”
“It’s really important to understand better where the profit or loss is coming from within a ﬁeld and manage this accordingly - this could mean managing higher yield potential areas to push for even higher yields if they are not treated as the ﬁeld average."
“Conversely in the higher performing areas of the ﬁeld is there anything limiting even better performance and could these areas be improved?
“Doing this in a coherent and effective way that considers all of the factors that may be affecting that particular ﬁeld or area of the ﬁeld is the challenge - but one that Omnia's unique ﬁeld performance mapping facility overcomes."
Using Omnia yield performance mapping, it's possible to identify and map areas of ﬁelds by categorising them in terms of the consistency of performance such as poorly consistent yield, good consistent yield etc- and adapt crop management accordingly.
This is exactly what Charles has done with one of his clients J&S Bealby, Lodge Farm, near Grantham in Lincolnshire.
“Yield maps in 2018 conﬁrmed a poor performing headland due to a combination of heavy soil and high shading from woodland." he points out. “This area will now form part of a mid-tier stewardship scheme planned for 2019. Income from Stewardship on this strip will make a positive contribution to the farm profit, rather than the loss from cropping it."
So, before you put your yield maps back in the draw for another year, think about how to use this valuable data about your ﬁelds to help you make the right cropping decisions for the coming season.
