Long grass on a pitch will reduce the distance rolled by a football. If the grass is short then the surface might be too fast for the semi-professional and amateur game.
A short grass surface will reduce the amount of root growth that takes place and this will reduce the amount of games that can be played because the grass will be more easily kicked out and worn away than a pitch that has a strong well-developed root system, which is created by a longer grass surface.
A wet pitch will generally slow a football down, reducing the distance it rolls. This will be particularly noticeable on pitches with less grass cover as the wet bare areas will effectively stick to the ball.
A pitch with less ground cover will offer less resistance to a football and so it will roll a longer distance than is there are high amounts of grass cover.
This might seem like a good idea, but less grass cover means increased chance of a muddier surface, a reduced root system with a less stable surface, a more uneven surface, poorer playing experience and more game cancellations.
