Topsoil is the nutrient-rich upper layer of soil essential for healthy plant growth. This calculator helps you determine how much topsoil to order for new lawns, raised beds, or improving existing gardens.
For new lawns, spread 4-6 inches of quality topsoil before seeding. Raised garden beds should have 6-12 inches depth for vegetables, 12-18 inches for root crops. When improving existing beds, add 2-3 inches of fresh topsoil and work it into the existing soil.
Quality topsoil should be dark, crumbly, and rich in organic matter. Avoid soil with clay clumps, debris, or strong odors. Screened topsoil has been filtered to remove rocks and roots. Blended topsoil mixes in compost for enhanced nutrition.
Topsoil compacts significantly when wet and settles over time. Order 10-20% extra to account for settling. One cubic yard weighs approximately 1.3 tons when dry, up to 1.7 tons when wet. Consider delivery fees - bulk delivery is economical for projects over 3 cubic yards.
Quick Tips
