Soil cracks are a unique feature of black vertisols. Evaporation loss is inevitable from lateral exposure of
surface and sub-surface cracks. On the other hand, these cracks provide increased opportunity for soils to recharge during
the rainy season. In this process, water that drains into larger size cracks moves down the soil profile and eventually results
in pothole formation due to the existence of a network of sub-surface cracks. An investigation was done to evaluate pothole
characteristics under different land use systems in black vertisols of central and western regions of India. In both the
regions, the potholes had smaller volume in arable land than in non-arable uncultivated land. The size and volume of
potholes in central India were greater compared to that in western India, where the highest volume of potholes was
registered under perennial vegetation followed by agriculture–horticulture system, uncultivated fallow fields and arable
lands. However, cultivated fields had less a incidence/occurrence of potholes than uncultivated fields. Similarly, the
marginal land in western India registered the highest volume of potholes than other land use systems. The study gives
insight to some of the researchable issues and strategies to minimize soil slumping in black vertisols, characterization of
soil properties within and adjacent to potholes as well as soil and nutrient loss through potholes.
