Spatial Distribution of Soil Nitrogen, Phosphorus and Potassium Contents and Stocks in Humid Subtropical North-Eastern India

Geo-spatial analysis for horizontal and vertical variability of bulk density, particle-size distribution and soil moisture content in Tripura, Northeastern India

“…The data on CVs values of BD showed low variability which may be attributed to uniform parent material in a large area under hills and mounds. Earlier, Reza et al (2019b) also documented a smaller variation of BD compared to other soil variables in the study area. Sand, silt and SMC showed high variability (CV > 35%) as compared to clay and the results are in agreement with the finding of Adhikari et al (2013) who reported a higher variability in sand compared to clay content.…”

“…Depending on their characters and the presence of fossils, these sedimentary rock sequences are divided into Surma group (the oldest), Tipam group and the Dupitila group (the youngest) (GSI 1998). According to USDA Soil Taxonomy (Soil Survey Staff 2014), the soils are classified as Typic Dystrudepts, Typic Hapludults, Aeric Endoaqualfs, Typic Endoaqualfs, Fluvaquentic Dystrudepts, Typic Endoaquents and Typic Fluvaquents at the subgroup levels (Bhattacharyya et al 2010;Reza et al 2019b).…”

Assessment of land use systems for CO2 sequestration, carbon credit potential, and income security in Vindhyan region, India

“…It promoted the decomposition of the OM that released a significant amount of NPK into the surface soil reflecting their higher value (Tang et al, 2016). Several researchers documented similar conclusions on the available NPK supplies in forest LUS versus cultivated fields (Duguma et al, 2010; Kharal et al, 2018; Reza et al, 2019).…”
