N min tests??

[Hindsight]

View attachment 1017837Two n-min tests.
The WOSR follows wheat which had digestate in wheat crop April last year and more on stubble before planting OSR first week in September. Pleased with the way crop looks but too wet to take a photo this morning.
The WW follows maize which had chicken muck and digestate before planting and wheat drilled first week November.
Thought residual n would be good so got agronomist to send samples off before the rain set in last weekend. But having got the results what do I do now?
Throw them in the bin and carry on as normal?
Do more tests in a month’s time? Soil, leaf or saps?

Sometimes ignorance is bliss!

im no expert. If the crop looks well I’d i follow the results 50%( if it says reduce by 100 units I’d reduce by 50). How much did it cost per test?

Agreed, haven’t discussed with the agronomist yet but I know he’s a little sceptical about relying on them to much. There does appear some scope to reduce rates more than I expected though.

We have done tests on odd occasions in the past and I have never reduced rates by as much as they recommend without any apparent yield penalty. I may have been too conservative so will probably reduce rates more this time. Didn’t ask the cost but shouldn’t be more than £100 and expect to save that in fertiliser over the 65acres of osr and 38 of wheat.

Yes but I did not dare cut rates by what it advised. Did as I said above. Going to try leaf tissue tests this year.
agrii were charging £118 this year. Test at lancrop £18.

Such is life. I did nmin tests after digestate and found sod all difference.

Personally, I'd put those in a file marked "nah"; go have a look in a week once it's dried; and see how lush your crop is. If it's forward, drop your first dose perhaps 20 percent and the second dose by ten percent. That's based on not feeding too much lush growth, and increased efficiency from good rooting. Third split as normal.

If you look on right NCalc gives a recommendation. 10kgs for the OSR & 77for the wheat. If you are unsure do a couple of tram lines as I did. Although looking closer you’ve put the OSR price as £200/t so that will throw the recommendation out

Yes, i had seen the recommendation for the n but was unsure how much to rely on it. I will probably have a play with some different n rates to see if I can learn anything. I only provided the soil, all the detail has been done by the agronomist or the lab but certainly £200/t for the rape is low but the recommendation for the amount of n required I thought would have been more driven by the soil n figure of 237kgn.
Got some pictures of the rape yesterday

Too wet to travel now but won’t be putting any n on for a while.

I think there is also an adjustment based on N & Crop Price
