One good rain can wash all the potash out of the straw.

And wash get into the soil or wash it away?

I am more concerned about the nitrogen. Some sources indicate that a large portion of the N gets volatized and lost, Unless it is Incorporated.

Zero soil moisture. Will put down enough at seeding for about 30 I'm thinking
Who counts straw nutrient uptake if you don't remove the straw?

That’s obviously for people who are removing the straw.
Duh

Okay makes sense now.
Just that nobody removes canola straw round here

Gotta grow it before you can remove it.

Gotta have enough nutrients for the grain production and the straw, root and leaf biomass as well.

Glad we get to leave our residue behind to help build soil and it's structure.

A good thatch can even help preserve moisture in dry springs.

Wet years it can turn into a Petri dish of fungal disease, oh well, enter vertical tillage(time and place).

the stover number still matters... You have to grow the straw in the current year.

Exactly and if you rely on mineralization too much without investing something back into your portfolio, the interest dwindles to nothing. Some of my challenging soils are solonetzic and most soil test regimes recommended do not pan out if other factors aren’t in your favour. All I know is keep the soil covered, leave residue, add residue (feed cows on it), fertilize for a realistic yield, and don’t grow barley.

One good thunderstorm can add 50ib/ac n in crop year.... A good pea crop can add another 100b/ac n the next 3 years... plus soil conditioning / nutrient avaliability/uptake is increased... 60bu/ac pea crop well chopped and spread= huge productivity gains after that pulse crop... fabas not so much...

We grow lots of straw here regularly, often problematic. It has gotten very trendy to bale it off. I would guess 85% of cereals were baled this year and a bit of canola straw. And there is no shortage of feed here, guys are just trying to get their baling back out of it. Seems counterproductive to me. I bale some every year but try to take it from the fields where I can replace with manure.

Why not Fabas ? I have been told the opposite , and the cereal crops I have seen here on Fabas look great .

True if this is the first year that the straw was returned to the soil. But if you have been putting the straw back every year for years or decades, at some point the mineralization of previous straw must cancel out the need to fertilize for the stover growth in the current year. If not, then where do the nutrients go?

Volatilization of the unstable variety and leaching of stable ones?
