I think you will find that method will work well at first and then you’ll start getting more and more grass issues when you go to spray it……eventually running into herbicide resistance. Its because if all you grow is clover long term then your C:N ratio is out of balance……not enough carbon to the amount of nitrogen. It causes you to start running soil carbon deficits over time. As the soil organic matter decreases this is when you start fighting those grasses harder and harder. I’m not trying to choose for anyone the route they choose to take…..only explain the science of what is happening. If you’re into soil building….long term pure clover is going in the opposite direction....you still have to bring in carbon to feed the soil long term to avoid those issues folks run into.....
