Allotment Planner Calculator — Crop Rotation & Plot Layout
Plan crop rotations and plot layouts for allotment gardening.
How We Calculate This
The calculator divides your growing area into four equal sections for a standard four-year crop rotation.
Path area is subtracted from the total to give the actual growing area. Path widths of 60cm allow wheelbarrow access.
The rotation plan moves each crop family one plot clockwise each year, preventing disease build-up and balancing soil nutrients.
