“…The decreasing trend of accessible Mn with soil depth may result from humic material deposition in the surface layers. The greater concentration of available Mn in surface soils was attributable to the chelating of organic compounds produced during the decomposition of crop residue and the addition of FYM [21]. These results were corroborated by a positive correlation of accessible Mn with organic carbon (r=0.356**) and a negative correlation with soil pH (r=-0.137**) (Table 3) [20].…”

Aims: An investigation was conducted to examine the distribution of available plant nutrients and the relationships between soil properties and available nutrient status in soil profiles in the Western Hilly Tracts of the Cuttack District, Odisha. Place and Duration of Study: The research area, i.e. the Narasinghpur block, is located in the western part of the Cuttack district in Odisha and is characterized by lateritic uplands and mountainous terrain. Three soil profiles were exposed i.e. upland, medium land and low land before the rainy season (February, 2020). Methodology: For experiments, five layers demarcated at 20cm intervals up to a depth of 100cm were sampled, processed, and stored. Several parameters, including particle size, pH, EC, OC, and available Ca, Mg, S, Fe, Mn, Cu, and Zn were analysed and interpreted using standard protocols. Results: Sand content decreased with pedon depth, whereas clay content showed the opposite trend. With increasing soil depth in all pedons, soil pH increased while EC and soil organic carbon content declined. The available Ca, Mg, and S in surface soils varied from 4.11 to 6.56 [cmol (p+)/kg], 2.15 to 3.54 [cmol (p+)/kg] and 9.85 to 12.06 mg kg-1, respectively. The corresponding subsurface ranges for these nutrients were 4.31 to 8.52 [cmol (p+)/kg], 2.41 to 4.52 [cmol (p+)/kg], and 6.95 to 11.41 mg kg-1, respectively. The available Fe, Mn, Cu, Zn, and B range in surface soils were 127.85-278.81, 68.48-144.98, 0.64-0.9, 0.54-0.63 and 0.37-0.47 mg kg-1, respectively. The subsurface ranges for these nutrients were 102.32–234.46, 53.21–118.28, 0.28–0.89, 0.17–0.50, and 0.29–0.91 mg kg-1. The status of micronutrients in the present study region was as follows: Fe > Mn > Cu > Zn > B. With increasing soil depth, available Ca and Mg increased, but available S, Fe, Mn, Cu, Zn and B declined. Positive correlations between available Fe, Mn, Cu, and Zn with the soil organic carbon content of the soil and negative correlations with the soil pH were observed. Conclusion: Plant nutrients in the research area varied with topography, although the differences between upland, medium land and lowland wasn't substantial. However, accelerated decomposition of soil organic matter and agricultural residues likely led to highermicronutrient concentrations at the soil's surface than subsurface.

“…The pedons in the volcanic group experienced more intensive washing during the rain due to a better soil drainage. The trend of pH increasing with more depth may be explained by the release of organic acids during the decomposition of organic matter, these acids may have lowered the pH at the soil surface (Satish et al, 2018). The pH differences of KCl and the pH of H 2 O of all pedons show negative values.…”

“…The soil texture of all pedons varies greatly between sandy clay loam, sandy loam, loamy sand, sandy loam, silty loam, clay loam, silty clay and clay, except for P7 that was of clay texture in all horizons. Wide variations of soil texture may be caused by the variations in parent material, topography, in-situ weathering, translocation of clays by eluviation and soil age (Satish et al, 2018). Apparently, the pedons located in the alluvial group were more dominated by clay fractions, although the distribution patterns were irregular.…”

“…These soil characteristics then form the basis for land classification. Combining soil characterization with classification is a powerful tool to develop management strategies for food security and environmental sustainability (Satish et al, 2018). However, the efforts to link land characteristics and classification with a specific land quality are still relatively rare.…”

Ten representative pedons from the Bulia micro watershed of Gorontalo Province, Indonesia, were characterized and classified to determine its land quality (LQ) class. Angular blocky, sticky, plastic consistencies and a hard consistency prevailed in the soil structure. In the alluvial plains the soil texture is dominated by the clay fraction, while in the hills and volcanic mountains the sand fraction is dominated. The soils in the Bulia micro watershed also have acid to neutral reaction, with the range of very low to high OC (organic carbon) levels, the reserve of exchangeable bases was dominated by Ca2+ in two series patterns, namely: Ca2+ > Mg+ > Na+ > K+ and Ca2+ > Na+ > Mg+ > K+, cation exchange capacity (CEC) ranged from low to very high, and the base saturation varied from moderate to very high. The alluvial plain is represented by Inceptisol in P1 and Typic Humustepts (P7), also by Oxic Humustepts (P3), then Mollisol on P4 (Typic Argiudolls) and Typic Haplustolls (P6), Alfisol on P5 (Typic Paleustalfs). Entisol on P2 (Typic Ustipsamments) was found in volcanic mountains and P9 (Typic Paleustolls) P8 (Ultic Paleustalfs), P10 (Inceptic Haplustalfs) are typical of volcanic hills. On the alluvial plains the land was categorized as the LQ class II, III and IV, the volcanic mountains were the LQ class IV, while the land on the volcanic hills was categorized as the LQ class VI. River bank erosion on the land river terraces can be held by the manufacture of gabions, talud, cliff reinforcement plants and terraces. The soil temperatures and high clay content can be regulated by mulching and organic materials.

Six soil series representing major coconut growing soils of the Eastern Ghats in Krishnagiri district of Tamil Nadu State, India, were evolved from granite gneiss and alluvium parent materials. Characterization of different soil properties was done using a detailed soil survey at 1:10000 scale. The soils were neutral to moderately alkaline in reaction (7.31 to 9.19), non-saline, poor to moderately well-drained and moderately shallow (<75 cm) to very deep (>150 cm) in depth. The soils were sandy to clay in texture, sub-angular blocky to crumb in structure, dark reddish-brown to brown, very low to high in OC content (0.06 to 2.70%), low to medium in AWC (3.44 to 22.39%), low to high in CEC (4.70 to 54.0 cmol (p+) kg-1) and having high base saturation (77 to 100%). The soils also had sizable amounts of exchangeable sodium (4.29 to 33.46%), which was maximum in P5, P6 and P1, and high clay content in P5 and P2. The distribution of CaCO3 in different depths was found to be maximum in P4 and P1. The soil orders identified in the coconut area were Inceptisols, Entisols, Alfisols and Vertisols. Assessment of soil resources and identification of yield-limiting soils factors on coconut could be by way of better management and improved productivity.
