摘要

This research aimed to examine the diverse physicochemical characteristics of soils influenced by different land use practices, focusing on lowland paddy fields, cultivated agricultural plots, orchards, and forest areas. Conducted research across the six villages, including Amaluma, Dhansiripar, Doyapur, Kiyeto, Melongmen, and Razhaphe in Dhansiripar Sub-division of Dimapur District, Nagaland, India. Multivariate statistical analyses, including multivariate analysis of variance (MANOVA), principal component analysis (PCA), and cluster analysis, were employed to evaluate the interaction between land use and location on soil characteristics. Results demonstrated significant variability across land uses. Soil pH (4.9–5.9) indicated strongly to moderately acidic conditions, affecting nutrient dynamics and microbial activity. Bulk density varied (0.96–1.29 g cm−3), and particle density (2.02 g cm−3–2.78 g cm−3) reflected differences in compaction, while porosity (41.09–58.39%) and water-holding capacity (32.87%–71.63%) highlighted contrasting aeration and moisture regimes. Organic carbon content (0.45–3.69%) exhibited pronounced variation, signifying differences in organic matter turnover. Macronutrient availability varied substantially, with nitrogen levels (250.88–752.64 kg ha−1), phosphorus (6.72–62.72 kg ha−1), and potassium (89.60–795.20 kg ha−1) showing land use-specific patterns. Cation exchange capacity (9.40–18.10 cmol kg−1) further reflected heterogeneity in soil fertility. The soil structural stability index (SSSI) revealed degradation of lowland paddy soils and differential susceptibility to structural decline under other land uses. Overall, the findings indicate that soils in the Dhansiripar region are highly prone to erosion and fertility loss under current farming practices. These insights underscore the need for land use-specific and sustainable soil management strategies to maintain long-term soil health and agricultural productivity.
