This study investigates the impact of agricultural practices on soil properties essential for plant growth and ecosystem health in Imphal Valley. Soil samples were collected from five distinct agricultural sites (Heingang, Khonghampat, Uchiwa, Langol, and New Keithelmanbi) and analyzed for pH, cation exchange capacity (CEC), organic matter, exchangeable Ca, exchangeable Mg, free Fe₂O₃ and Al₂O₃. Soil pH ranged from 4.7 (acidic) to 6.4 (slightly acidic) across locations, indicating the need for potential amendments in some areas. Moderate variation in organic carbon matter (32.4-39.3 g/kg) was observed, highlighting the importance of organic matter management for soil health. Cation Exchange Capacity (CEC): CEC values varied notably (5.9-9.6 Cmol(P⁺)kg?¹), suggesting the influence of factors beyond organic matter on nutrient retention capacity. Significant variations in exchangeable calcium and magnesium levels were observed, potentially impacting nutrient availability for plants. Higher organic matter content correlated with higher CEC, while lower pH corresponded with lower exchangeable magnesium. Heingang exhibited high organic matter and CEC despite low pH, highlighting the need for pH adjustments. Uchiwa showed soil properties with near-neutral pH and high nutrient levels. Langol exhibited low CEC despite high organic matter, suggesting the influence of other soil characteristics. The study revealed significant variations in soil pH, organic carbon, and CEC, highlighting the importance of site-specific management practices. Strategic amendments like liming for acidic soils and organic matter enhancement can optimize nutrient availability and promote sustainable agricultural productivity in Imphal Valley.
