It will co-fund an England and Wales network of IoG Regional Advisors and the IOG/ECB Fine Turf Project Manager.
ECB Facilities & Funding Manager Bruce Cruse said: "This substantial cash injection reflects not only how the IoG is recognised by cricket grounds managers as the first port of call for fine turf technical help and advice, but it also clearly demonstrates the increasing success of the IOG's vision in creating an industry-wide network of groundscare experts who offer indispensable advice and experience."
Cruse made the announcement at the recent ECB Pitch Advisors meeting, adding that he hoped the ECB's support would help encourage other sports' governing bodies into following suit.
The IoG has three advisors in post in the North, Wales & the South West, and in Scotland (funded solely by the IoG), plus a fine turf manager.
New advisors are currently being recruited for the Midlands and the South East.
IoG chief executive said the regional advisors maintain an effective link between head office and the regional branch network.
Adding: "(They) are critical in taking the IoG forward in terms of reaching out to and liaising with the country's 20,000 strong body of volunteer groundsmen. This enormous contribution will make a real difference and I thank the ECB for its continued support. We have an excellent ongoing relationship with the ECB which includes a comprehensive programme of training/CPD and there's no reason why this success should not be mirrored in other sporting sectors."
