I was talking with some friends that said in Nova Scotia, gravel baseball infields were all they have every played on. I had never seen a gravel infield until I moved up here. Is there a specific reason for the gravel infield over a clay infield? We thought it might be weather related or money related, but cannot find any information via Google.
Gravel fields are for basically two reasons:
The climate of the region would mean that the field would take a long time time to dry or would be wet most/all of the time. If you are putting a baseball field up north it is more important that they have a field to play on vs. having a good field. If it is rainy 2-3 times a week and 40-50F during the spring your fields will never dry. Gravel can be played on the next day.
The soil is so rocky that you might as well gravel it. This is less common but seen it in South America.
The largest contributing factor for my area would certainly be maintenance. Without a dedicated baseball infield maintenance team, it would be difficult to maintain a playable clay surface. We don't have the funding for that so gravel seems to be the best option at the moment, as well as the weather/wet conditions.
