What are soil 'aggregates'?

Tracy DiSabato-Aust (Garden Designer and Author) gives expert video advice on: What are 'soil amendments'?; What is the difference between 'organic' and 'inorganic' soil amendments?; What is 'leaf humus'? and more...

Soil aggregates would be things like pea gravel. We also use Chicken Grit even, as an aggregate. And I will use aggregates ( gravel, grit) in my heavy clay soil that's poorly drained, when I want to try to grow a plant that requires better drainage. You need to actually line the hole with the grit and plant the plant, and then actually even use it as a little bit of a mulch to help keep moisture away from the crowns.
