Loam vs. Sand — What's the Difference?

By Tayyaba Rehman & Maham Liaqat — Updated on April 20, 2024
Loam is a rich soil type ideal for gardening due to its balanced mixture of sand, silt, and clay, providing excellent drainage and nutrient retention, whereas sand is coarse, drains quickly, and holds fewer nutrients.

Difference Between Loam and Sand

Key Differences

Loam is valued in agriculture and gardening for its optimal blend of different soil particles, which promotes water retention and aeration, while sand, predominantly consisting of coarse particles, tends to drain water very rapidly.
The texture of loam is soft and crumbly, which makes it easy to till and beneficial for root growth; on the other hand, sand has a gritty texture and does not hold together well, posing challenges for stabilizing plant roots.
Loam is typically fertile, supporting a wide variety of plant life due to its ability to retain nutrients effectively, whereas sand is often nutrient-poor and may require significant organic amendments to support healthy plant growth.
Because of its balanced structure, loam is less prone to compaction compared to other soil types, enhancing root penetration and moisture management; sand, however, despite not compacting, offers less support for roots due to its loose structure.
Loam maintains its moist consistency, which is ideal for most plants, while sand tends to dry out quickly, requiring more frequent watering to sustain plant life.
