Assessment of physical properties of soil under various agricultural land in Imphal valley of Manipur, India


Samom Bidyalakshmi Devi and Thokchom Biren Singh

This study investigates the spatial variation in soil physical properties across five agricultural land-use sites (Heingang, Khonghampat, Uchiwa, Langol, and New Keithelmanbi) within Imphal Valley. The analysis aims to elucidate the significance of these properties for maintaining ecosystem health and promoting sustainable land management practices. Soil physical properties were evaluated through analysis of mechanical composition (sand, silt, and clay content), bulk density, particle density, porosity, water-stable aggregate stability, gravimetric moisture content, and water holding capacity. Soil texture analysis revealed a predominantly clayey composition with variations across locations. Heingang possessed the highest clay content (51.5%) followed by Langol (66.9%) and New Keithelmanbi (52.4%). Conversely, Uchiwa exhibited the highest sand content (40.7%). Bulk density (1.28-1.39 Mg/m³) and particle density (2.33-2.56 Mg/m³) influenced soil compaction and water retention capacity. Porosity ranged from 43.3% to 47.8%, impacting water infiltration and nutrient availability for plants. Remarkably, high water-stable macroaggregate percentages (83.9%-94.4%) indicated good soil stability. However, variations in moisture content and water holding capacity were observed. Heingang displayed the highest available water capacity (0.37 m³/m³), while Khonghampat exhibited the lowest readily available water content (0.27 m³/m³). Correlation analyses revealed significant relationships between soil properties, informing management strategies. Particularly, strong correlations between bulk density, particle density, and water-stable aggregates were observed in these clayey soils. These findings emphasize the necessity of understanding soil physical properties to enhance soil health, optimize land management practices, and ensure sustainable agricultural productivity in the region.
