The Vego Garden Raised Bed Soil Calculator helps determine the amount of soil needed for raised garden beds using simple length, width, and depth measurements.
The calculator uses the volume formula:
Where:
Explanation: The equation calculates the cubic feet of soil needed to fill a raised garden bed to the desired depth.
Details: Proper soil calculation ensures you purchase the right amount of soil, avoiding waste or shortage. It also helps with proper plant spacing and nutrient distribution.
Tips: Measure your raised bed's interior dimensions in feet. For irregular shapes, break into rectangular sections and calculate each separately.
Q1: Should I add extra soil for settling?
A: Yes, it's recommended to add 10-15% extra to account for soil settling over time.
Q2: How deep should my soil be?
A: Most vegetables need 12-18 inches of soil depth, while shallow-rooted plants may need only 6-8 inches.
Q3: Can I use this for circular beds?
A: For circular beds, use the formula: π × radius² × depth (radius = half of diameter).
Q4: How do I convert cubic feet to bags?
A: Most soil bags contain 1-2 cubic feet. Divide your total cubic feet by the bag size to determine quantity needed.
Q5: Does this account for amendments?
A: No, this calculates total volume. You'll need to adjust ratios if mixing soil with compost or other amendments.
