Turfgrass managers always treat Sand. A sand has particles of different sizes and combined that form particles the particle sizes, of which I showed examples in this post.
The particle socket distribution cards can be difficult to read if you don’t often look at it. I will actually admit that I sometimes find them a bit confusing, even when I look them often.
What about looking at a single number from the particle sizes – the diameter of the average sand particle in the sample? This is a term for – the D50. The D50 Is the diameter where 50% of the mass of the sand particles will have a smaller diameter and 50% of the sand has a larger diameter. It is the sieve size on which we could share a sand sample in two. We could take a sand sample, put it on that sieve and after shaking, half of the sand would stay on the sieve and half of the sand would have continued.
I made This graph To summarize the D50 Values for 302 different well green sand. This sand is from all over the world and they represent root sun materials, usually, together with some top dressing -sand.
I also calculated what the D50 would be for a sand on the limit of the USGA recommendations on the fine side, and what the D50 Would be for the very coarse sand that would meet particle size recommendations.
15% of the sand in my database (45 out of 302) have a D50 Smaller than the USGA Fine Limit.
