Orchard Canopy Volume Calculator (TRV)

Calculate Tree Row Volume (TRV) from tree height, canopy width, and row spacing, then see spray and pruning references together.

A geometry-based guide that also works for orchard crops beyond grapes.

TRV from three orchard measurements Spray and pruning references in one view Metric and US units, shareable links, and autosave

How to use

Measure tree height, canopy width, and row spacing, then choose the unit system.
Choose the canopy profile and orchard condition to update TRV, spray volume, and pruning references.

Sample

A typical orchard example

Input Tree height 3.2 m, canopy width 3.4 m, row spacing 4.0 m, canopy profile: rounded, orchard condition: balanced

Output TRV 20,400 m³/ha (291,500 ft³/acre), spray volume 2,320 L/ha (247.81 gal/acre), target width 2.8 m, current 3.4 m -> reduce by 0.6 m

How to measure the canopy

Measure canopy height to the top of the leafy canopy, and use the average canopy width.
Measure row spacing center to center.
If trees vary, use the average values.

Formulas

Row length/ha = 10000 / row spacing (m)
TRV (m³/ha) = tree height (m) x canopy width (m) x row length/ha x shape factor
TRV (ft³/acre) = tree height (ft) x canopy width (ft) x row length/acre x shape factor
Spray volume (gal/acre) = TRV (ft³/acre) / 1000 x orchard condition factor
Spray volume (L/ha) = spray volume (gal/acre) x 9.353946
Target width = row spacing x target fill ratio
Width reduction = max(canopy width - target width, 0)

Glossary

TRV

Short for Tree Row Volume, a per-area measure of orchard canopy volume.

Canopy shape factor

A factor that reflects whether the canopy is pointed, rounded, or square.

Orchard condition factor

A factor that reflects canopy density for the spray-volume reference.

Row fill ratio

Tree width divided by row spacing; a measure of how fully the row is occupied.

Target width

A reference width target derived from the orchard condition.

FAQ

Does this give the exact pruning answer?

No. It is a geometry guide that shows the width to trim and the target width reference. Actual pruning still depends on species, training system, and season.

Can I use it for crops other than grapes?

Yes. Because it works from canopy geometry, it is useful for apples, pears, peaches, citrus, and other orchards too.

Is the spray amount a label rate?

No. It is a dilute spray reference based on canopy volume. Follow the product label separately.

What if canopy width exceeds row spacing?

The calculation still runs, but we show an overlap warning. Use it as a reference for stronger pruning or retraining.

Notes

This is a reference only. Suitable values vary by tree species, rootstock, vigor, season, wind, and equipment conditions.
Treat pruning as a width-adjustment guide, not as a count of branches or labor time.
Spray volume here is not a label rate. Follow product-specific instructions first.
