Slope

Category

Degree of tilt

Description

Flat to gently undulating

A

0-3°

Horticultural machinery could operate on these angles

Undulating

B

4-7°

Some of this land is too steep for some horticultural machinery but this is croppable land from a slope perspective

Rolling

C

8-15°

This is croppable land from a slope perspective. This land should be cropped parallel to the contour for soil conservation purposes.

Strongly rolling

D

16-20°

This is croppable land from a slope perspective but it is dangerous to cultivate parallel to the contour. This should only be cropped occasionally. Cropping should be avoided with some highly erodible soils.

Moderately steep

E

21-25°

This land is too steep to cultivate with wheeled machinery but can operate two wheeled farm bikes and horses.

Steep

F

26-35°

Too steep for farm bikes.

Very steep

G

>35°
