Question

what does the usda land capability classification system categorize land based on? limitations to root development and tillage operations climate assessment topographic analysis risk of runoff and erosion

Explanation:

The USDA Land Capability Classification system categorizes land based on the risk of runoff and erosion. This system is designed to evaluate the suitability of land for agricultural use, with a primary focus on soil erosion potential. Erosion is a critical factor as it directly impacts soil productivity and long - term land usability. While other factors like root development limitations, climate, and topography are relevant in land evaluation, the USDA's Land Capability Classification specifically emphasizes the risk of runoff and erosion.

Answer:

Risk of runoff and erosion
