Last week I was working in the garden. There were several trays of
seedlings that have been planted in  commercial potting soil - the
mixture had a very small amount of fertilizer. The plastic seedling
containers sat in 1/4" of water. As I approach the area  it was obvious
that a drinking station had been setup. There were several hundreds
of bees sitting on the moist dirt, I assume drawing water. The 12 hives
that were using the dirt water, sit 10' to 20' from a year around creek.
Why did they choose the dirty, fertilized water? Minerals?
