The ceremony saw children from the surrounding areas given the chance to grace the new turf and enjoy sessions run by The FA Skills team.
And local disability side Langford Tigers also had the opportunity to showcase their skills and test out the new carpet.
"This, for me, is what grassroots football is all about," said Dyke.
"I think at grassroots [level] we will increasingly see football played on these surfaces, not exclusively, but they are so much more economical and make sense being lovely playing surfaces like this one.
"We all know local authorities budgets are tight, so they can’t maintain the grass pitches like they have done in the past, but if we can build more of these, like they did in Germany and Holland, then I think it will do a lot to help grassroots football."
The project to transform the existing grass pitch to an artificial surface, at a cost of over £400,000 was funded by the Sussex County FA with the support of Barclays.
And it took just 65 days from the first blade of grass being taken up, to FIFA inspecting the freshly laid surface, with the project handled by Surfacing Standards Ltd, Velocity Elite Sports Surfaces and Lano Sports.
"It’s fantastic that this project here has been funded with a loan from Barclays, and that’s given me food for thought as to whether The FA could help guarantee these types of loans, as opposed to giving the money," added Dyke.
"That way, we may be able to do many more of these quickly… it’s a very interesting idea and I applaud the Sussex County FA for demonstrating that this is possible and quite clearly that it works, as this is absolutely brilliant!"
Next month will see Sussex host the England Under-21s, when they take on Switzerland in a Euro Qualifier at Brighton & Hove Albion’s Amex Stadium.
