Nitrogen in the soil

[Kildare]

Today was my first day spreading fertlizer on the no tilled field of ww.It was firm as a road to travel on and the wheels of the tractor were perfectly clean. However the wheat is not as green as the ploughed fields.
I know this is due to the mineralisation of nitrogen. Is the nitrogen that is not mineralised in the no till available later in the year when the soil warms up.

yes ...research work shows that by the time the crop gets to harvest theres the same amount of N in both DD and ploughed crops

By the same token as one dimunates yield N concentration will balance against higher yield. Whilst no till provides cost advantages and agronomic advantages it does not provide a greater production to feed a burgeoning global population. It is but a sexy toy which has it's place in the greater scheme of things.

Elmsted, would you mind translating this please. I've read it several times - there's no such word as 'dimunates' which is the first drawback, but even when I replace that word with 'decrease' or 'diminishes' or 'reduces' it still doesn't make sense.

'As one reduces' yield N concentration will balance against higher yield' ???

I'm always interested in what you say as you have an alternative take on things. I can't make head nor tail of this posting though. Sorry!

The word to reduce or to lower the level of concentration of an element does exist.
As an example if one refers to malting barley wherein the end user wishes a low level of nitrogen due to feeding of bacteria. The farmer producer is left with two options namely to grow a low yeild with low N input or to grow 6 row barley with 10 tonne hectare yield. Both achieve the same objective in complying with contractual requirements.
So therefore soil N as per thread title is relevant. And in my view so oft expressed the need for leaf tissue testing.
