What does Class 4 of soil capability classification indicate?

Class 4 of soil capability classification indicates that the soils are marginal for sustained arable culture. This means that while these soils can support some forms of agricultural activity, they have limitations that may include factors such as poor drainage, low fertility, or susceptibility to erosion. These limitations make it challenging to maintain continuous crop production sustainably over time.

Class 4 soils may require significant management or improvement strategies, such as crop rotation, cover cropping, or the addition of organic matter, to enhance their productivity and sustain agricultural practices. Understanding this classification helps farmers and land planners make informed decisions about land use and soil management practices that align with the potential and limitations of specific soil types.
