RE: [compost_tea] Re: Soil Sampling



Kevin, I agree with Ted's comments of leaving a part of the field unsprayed, and wanted to add this concept of a "control" to my previous post.  Without some kind of a control you really can't say that your action (using the ACT) was the cause of the good result.  You really need to show that "doing nothing" or "doing the conventional way" was worse.
 
Because this is not your property, because the field must be used by others, and because the field must look good (or, somewhat uniform), I would suggest you find hiding spots that you can leave as a control.  You mark them on your map.  Another way is to place these hiding spots on the fringes of the main area where they will not be seen.

Hello, Kevin.

Congratulations on your baseball grounds maintenance contract.

I think your demonstration will be most convincing if you leave part
of each field unsprayed, treating it in the "conventional" way, or
alternatively, if you treat adjacent fields with compost tea and with
a conventional approach.  This will allow side-by-side comparisons,
including soil analyses, at any point in time. As long as everything
looks good at all sites, you'll only need to do your soil tests at
one site.

The problem with treating everything with CT and then sampling over
time is that things other than your CT treatments (such as weather)
might affect your readings, making it difficult to make convincing
comparisons between before and after readings.

Just my two cents worth.

Good luck.

Ted Carey
