Structural status of soils under different land uses, viz. aerable, native grass land, tea planting and native forest, was studied using different structural indices. Land use showed a significant influence on soil structure. Water-stable aggregates (> 0.25 mm dia), mean weight diameter and total porosity were significantly higher, whereas bulk density was significantly lower in tea than in aerable soils. In general, tea soils showed better structural status than other soil groups. It was observed that use of one index alone is not a satisfactory approach to soil structure evaluation.
