摘要

A study was conducted to characterise soil under different land use systems of Medziphema Block, Nagaland (India) during 2021-22 at the School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema, Nagaland (India). The results revealed that the minimum bulk density (1.11 g cm− 3) was found in the forest land system and maximum porosity (50.88%) was recorded in the forest system. Results showed significant differences, with forest (teak, bamboo) and agroforestry systems (LUS-1, LUS-4) maintaining superior soil health through lower bulk density, higher porosity, greater SOC, higher CEC, and enhanced nutrient availability. The highest cation exchange capacity (22.5 cmol (p+) kg− 1), organic carbon content (37.6 g kg− 1) was found in forest land use systems. However, the highest available nitrogen (491.5 kg ha− 1) was recorded under the agroforestry land use system. The study establishes a clear soil quality gradient (Forest > Agroforest/Orchard > Agriculture) and identifies species-specific effects on soil fertility. By integrating physical and chemical attributes, it highlights SOC as the central driver of soil quality, offering novel strategies for sustainable land-use planning and restoration of degraded alkaline soils.
