Soil properties and organic carbon distribution under different land uses in reclaimed sodic soils of North-West India

Assessing soil properties and nutrient availability under conservation agriculture practices in a reclaimed sodic soil in cereal-based systems of North-West India

“…It was highly sodic with high pH (1:2.5) of 10.3 and exchangeable sodium of 97% at 0–5 cm depth in 1970. ICAR-Central Soil Salinity Research Institute was established in 1969 and developed reclamation technologies particularly addition of gypsum and adoption of best management practices for cereals, thereby the soils were reclaimed and cultivation of crops started (Datta et al 2015). The soil of the experimental field was loam in texture, low in organic carbon with slightly alkaline pH.…”

Evaluation of saturated hydraulic conductivity from soil properties in an Inceptisol using different land cover and depths

“…Its values differed when estimated in soilwater (6.3-6.8, mean 6.5) suspensions. Variations in acidity among the soils were due to production of organic acids by decomposition of leaf litter and their difference in biochemical composition (Datta et al, 2015). Soil under Jhau plantation recorded the highest value (6.8 g kg -1 ) of OC followed by Sagun and Sissoo (5.8 g kg -1 ), Lamboo (5.7 g kg -1…”

“…This was possibly due to the fact that higher clay and organic matter contained different functional groups like carboxyl, phenolic and enolic contributing to the exchange capacity of the soils (Deb et al, 2016). Depth increment gradually increased the soil pH and decreased OC content and CEC in the soils irrespective of cultivated soils (Table 2) (Datta et al, 2015;Deb et al, 2016). Physical properties of soils under forest trees: Relative proportion of sand, silt and clay ranged from 12.5-17.1, 32.8-38.0 and 47.7-50.8% with the mean values of 14.4, 35.5 and 49.4%, respectively in soils under forest trees categorized as silty clay (Table 3).…”

“…The highest value was associated with Sagun (46.2%) followed by Sirish The highest porosity in soils under Sagun plantation was possibly due to voluminous leaf litter deposition. Bulk density typically increased along depth in studied soils irrespective of plantation since sub-surface layers have reduced organic matter, aggregation, and root penetration compared to surface layers and therefore, contain less pore space (Datta et al, 2015;USDA, 2008). The saturated hydraulic conductivity of the soils under tree plantation was found to be more or less similar with a mean value of 0.84 cm hr -1 .…”

Variation in Soil Properties and Carbon Stocks under Roadside Plantation and Rice-Wheat Cropping System in North Western Haryana, India

“…However, micronutrient status in the soils was not targeted in this study. Higher BD in RW cropping system might be due to low organic matter input and compaction by the heavy vehicles like tractors (Datta et al, 2015;Chaudhari et al, 2015a).…”
