Manage and Improve Silt Soil

Updated: Apr 15, 2022

Silty soil looks gray and soapy. It's similar to clay and forms from sediment of watersheds. Silt sediment collects at deltas like in Louisiana.

Silt retains water, contains higher nutrients, and tends to clump together. Mix in compost and sand to improve upon drainage. Silt warms slowly like clay.

Pros: It holds moisture and has more nutrition.

Cons: Amend with organic humus to improve drainage, structure, and nutrition.

Vegetables: Most crops provided adequate drainage.

Ornamental: Mahonia, New Zealand Flax, shrubs, climbing vines, Willow, Birch, Dogwood, and Cypress trees.
