Which soil capability class has the most severe limitations for producing crops?

Class 5 soil capability is associated with significant limitations for crop production. This classification indicates that the soil is often too rocky, wet, or has other adverse conditions that can severely restrict the types of crops that can be successfully grown. Typical challenges include poor drainage, low fertility, and susceptibility to erosion, which all hindrance successful agricultural use.

In comparison, Class 3 and Class 4 soils have moderate limitations, meaning they can still support crop production but may require management practices to improve conditions. Class 7 is primarily designated for non-agricultural uses, as its limitations are even more severe than Class 5 soils, often rendering them unsuitable for cultivation altogether. Thus, Class 5 is the appropriate choice as it represents the soil with the most severe limitations among the cropping classes mentioned.
