Trust A North American Brand For Your Infield Mix

Recently, I have gotten a couple of emails asking the question, what’s the infield clay actually made of? In layman terms, it’s composed of three substances. Sand, clay, and silt. The question is what are the percentages of each material’s material, and the particle size of the sand. The composition is the true science of the infield clay even though the daily maintenance performed on these areas in a higher degree is sometimes considered more of an “artwork”. Most firms that offer ball diamond mix state they have a something like a 60 percent-70% sand ….20%to 30 percent clay and 10% to 20 percent silt. Most clays and baseline clays are approximately 5 inches deep. Below that there is an amount of sand and pea gravel on the big league fields.

As a general guideline, this distribution makes sense, but the essential factor is the sand particle size which comes in numerous variations from “gravel” to “very very nice”, Angular and around and so on. Tests are conducted to determine the percolation rates that give you an idea on how it may drain or dry out and distributions of materials in addition to the sizes. Normally clays don’t drain very well and aren’t really supposed to depending on the degree of the area you have. You are able to obtain any kind of blend you would like from clay businesses that are numerous. The location and your financial plan will drive your choice.

Once I worked for the City of West Palm Beach handling the spring training center for the Atlanta Braves and the Montreal Expos we used a greater sand base 75% sand 15% clay 10% silt with a medium course level sand that allowed the rain to pass through the infield clay a little easier. These days I use a clay using 10 — 20 silt and an investigation of 40% oil 50% sand. This is a mix that is hefty that is genuine but can take a lot of abuse. Where you live and the field is utilized drives the decision on the sort of clay that is infield you may have.

Keeping up the infield’s moisture level requires constant monitoring and maintenance. Coaches and players are giving feedback to you on the state of the infield assisting you to decide where you need to be with the upkeep and moisture methods used. Dependent on time of year, climate, the weather and even the staff that’s in the area, a little can change. It’s one of those interactions that are unknown. That’s why they sometimes call the groundskeeper that the 10th person on the team!

Infield Mix, Ball Diamond Clay, or Baseball Dirt

When considering what to do to your area, the first thing you should look at is the dirt level of the skinned area. Over 80% of the areas we look at desire soil (infield mix). Fields that are low on dirt drain. Fantastic dirt will be noticed from the players; including dirt will resolve spots on an area which cause wet stains and ball behavior.

It is ideal to include baseball dirt at the autumn or following your season ends. Baseball dirt is much more available in the autumn than in the spring. The off season will allow the dirt to settle without players while the dirt is not loose, adding traffic. Unfortunately, this task often gets forgotten until a couple of days before everybody starts to play. Dirt providers will add top soil from the spring, which is not desired to the baseball combination.

We’re currently using a mix of 65% sand, 35% clay; that we call Frazier’s Select Baseball Dirt. We’ve applied this infield mix at more than 50 baseballs and softball fields. We’re quite happy with the outcomes. It is firm enough to make for hops, but not difficult in the rainy summer months. We’ll sell this product nationwide, but it is really economical in New York, and Ohio, Michigan, Indiana, Kentucky, Tennessee, Georgia. Shipping rates beyond these states drive the cost up. As always, it’s important to purchase locally.

Many other infield combinations are used. I’ve seen mixes of clay but it needs a great deal of care. Clay mixes have to be watered before the game begins and occasionally watered throughout the game. This can be impractical for lesser levels of drama.

It’s very important to get dirt that’s free of rocks or other contaminants. Don’t use top soil for baseball grime.
