Garden microscopy

Microscopy of sample of earth from garden pot in Lichfield 3/9/2017

I looked at a sample of earth from a garden pot today – to see if the organisms present varied from those in Stowe Pool yesterday. Objectives used included x4, x10, x20, x32, x54, x100.

If you thought that the dirt in your plant pots looked like it was just dead rubbish, then look at the video below – it is alive!! Mostly ciliated organisms and diatoms, also multicellular organisms, also ciliated as can be seen by their movement. Lot of single celled protozoa. At higher magnifications, small numbers bacteria could be seen (with x100 objective – even though it was not a phase objective, I did use phase plate though to view these bacteria and it significantly helped to show them).
