RE: [compost_tea] Soil Sampling



Re: Soil Sampling on baseball fields
 
Kevin, maybe you should do your tests on the same days each year so you can say that the samples were taken at (relatively) the same points.  I would also track the rain fall in the area, before, during and after, and other important variables, besides ACT, that could explain the differences.
 
I would also recommend that you document your tests on paper thoroughly.  Making a map of each site and marking the sample areas would be important (maybe count the steps to each sample area).  Each area could have different soil, drainage, and other growing conditions.
 
As a final idea, if you don't send SFI samples from each area, then why don't you make a blend of each field and send in a soil sample to SFI for testing from each designated ball field.
 
When you say that the dilution will be dependent on weather and mood, the application rates and dilutions should be fully documented on your records.  I'm sure you will want to review these long afterwards, and they may indeed explain the results in a different way than you thought.
GOOD LUCK!  It sounds like an exciting test.
