Soil analysis and flat crops

[warksfarmer]

Anybody ever looked into this? Got a field that every year the crops go flat. The last osr crop back in 2012 went down and since then in no particular order - spring barley, spring wheat, winter rye, winter wheat and even a couple of cover crops (mainly mustard) have gone flat in places.
Prior to 2012 I can’t recall it happening unless we had really bad wind/rain combo at the same time so I’m wondering if it’s soil based.

Stem based disease buildup? If you're cutting down on fungicide, esp t0 etc, and not ploughing you could be building up various nasties.

Low K?

 

[Bury the Trash]

Too much N

 

[PSQ]

Not enough Grafton

Just one field though. Everything else treated the same.

225kg this year milling wheat.

Same yield as other fields?

Historically yes. Not sure yet this year but gut feeling slightly higher.

Nope

This is only a guess but could it be to much K?
I’ve found on one of our crops that is quite susceptible to going over it’s the overlaps of K that are the worst or go over first. I’ve got one especially bad patch where I forgot to shut one side of the spreader off.

I know it's what the tree huggers on here say, but sometimes I think you just get the soil biology right on a field and everyone else clicks into place. So much more nutrients become available to growing crops.

Don't ask me why or how. But I've fields the same. Unfortunately not farms.

What’s the Mg level?

Field with high inherent fertility after long term grass manure use
was it grass ploughed up in the 1980s but not cropped between 1920 and 1980
deep soil warm early field with high establishment rates drill early
loose fluffy soil

all possible factors

How long do you reckon these long term grazing fields keep their extra fertility for? Ive a few

We amalgamated a field of “100 year grass” into an arable field in 1986/87. I could make out the greening effect on that area until about 5 years ago, so about 30 years.

We have a 30ha field which had 8ha of Gallops in it until the ‘80’s
That area was the first to go flat in Spring Oats this year, it’s normally the better end of the field most years
