It is beneficial to have low nutrient levels in soil for wildflower.
And it is sometimes advised to take off the top 10 to 15cm of topsoil, but this is a lot of soil on a half-acre, about 30 truckloads
You can also reduce nutrients by simply taking off the cut grass without fail and the nutrients go with it.
Or if you want to speed up things; you can add ground limestone at about 500grams per square metre, as the lime locks up nutrients.
