The classification of land capability based on slope percentage indicates the type of use that is appropriate for the land concerning its physical limitations. A slope of 30-60% presents significant challenges for agricultural practices due to the increased risk of erosion, difficulty in machinery operation, and limited water retention. These factors severely restrict the land's suitability for conventional crop production. Therefore, categorizing this slope range as "restricted for agricultural" accurately reflects the limitations and risks associated with farming on such steep terrain. This classification aids in making informed decisions about land use and management while promoting sustainable practices that consider environmental impacts.

Other classifications do not suitably describe the conditions presented by this specific slope range. For instance, non-cropland may suggest that the area is never suitable for agriculture, which isn't necessarily true; it may still have uses but is not ideal for conventional farming. "Very severe limitations" could imply an even greater level of restriction than what is warranted by the conditions at this slope. Lastly, "few limitations" would be inaccurate for such steep slopes that pose considerable challenges to agricultural viability.
