Soil core samples with evidence of Oxidation and Reduction

[@katedwek7785]

Really cool video that helped my understanding of soil redox-thank you.

Hummus is a food, humus (pronounced hyoomus), is the organic layer. But great video! Thanks.

This is a great video! How long had these samples been exposed to oxygen for before you took this video? How quickly does oxygen act on the gley soil?

We took these core samples about 15 months before I recorded these videos. The samples were kept in ziplock bags all that time.
