N doesn't need to come from a bag, every % of SOM can release 8kg N/ac if well managed.
Clover (again if well managed) can produce 60kgN/ac.
At a conservative estimate to allow for less than ideal farming practices.
With a SOM of 3% x 8kgN- 24kg
W clover- 50kg
Total 74kg N
It is highly unlikely that old PP will use that level of N so some if the excess is highly likely to just be wasted through leaching, particularly in high rainfall areas.
If grass is just yellow stems it would suggest poor farming practices.
I'm not sure why it's often assumed that ploughing is required to establish a new ley or improve an old one.
There are many different methods to do this that are lower cost and don't need to disturb soil structure.
That soil disturbance could improve overall soil health and up natural N production.
New longterm leys could improve clover and provide a grass swad that could harness and utilise the aforementioned natural N.
