Straw usage on fields

In real life there is a difference whether you remove the straw from your fields, or is chopping an spreading it on the soil .. There is a gain by not removing it, and a loss by doing it ... But at the same time, you need to add a bit more nitrate to soil where you are chopping the straw, because the process of releasing the nutrients from the straw, demands a bit nitrate in order to happen... And furthermore you need to add more Lime, in order degrade the straw (the process makes the pH sink)
