“…Lower horizons of pedon 4 had highest cation exchange capacity (22.20 to 26.80 cmol (p + ) kg -1 ). The higher CEC in pedons 3, 4, 7, 15, 18 and 21 may be related to variation in content and nature of organic carbon and inorganic colloids (Sireesha and Naidu, 2015). Sawhney et al (1996) evinced that the wide variation in CEC among different landscapes of Shiwalik hills of Punjab may be assigned to difference in clay content and stratified and young nature of materials.…”

“…This may be due to higher amount of quartz in parent material (Ahuja, 1981;Khan et al, 1997). Sireesha and Naidu (2015) reported that the values of SiO 2 and Al 2 O 3 reflect the presence of appreciable amount of 2:1 type of clay minerals. Walia and Rao (1997) reported that SiO 2 varied from 59.7-76.8 % which may be attributed to the nature and source of alluvium in Trans-Yamuna plains.…”

“…Yadav (1999) (pedons 2, 5, 8, 17, 18, 20, 22). The presence of CaO and MgO infer the occurrence of minerals rich in calcium and magnesium (Sireesha and Naidu, 2015). Sodium oxide (Na 2 O) and K 2 O were present in low amount, i.e, 0.26 to 1.87 and 0.50 to 3.80 percent, respectively.…”

The study was carried to determine the mineralogy of soils of different geomorphic units for providing the more detailed information needed to improve agricultural production in north-eastern part of Haryana. The soils of the study area were slightly acidic to strongly alkaline in reaction (6-9.4). The cation exchange capacity and electrical conductivity varied from 3.10-26.80 cmol (+) kg-1 and 0.16-1.20 dSm-1, respectively. In general, the soils were siliceous in nature with SiO2 ranging from 68.60 to 87.90 percent. The soil samples from surface and subsurface diagnostic horizons were studied through X-ray diffraction. In fine sand, quartz was the dominant mineral followed by feldspars, muscovite, hornblende, tourmaline, zircon, biotite, iron ores and sphene. In silt fraction, quartz was the dominant mineral followed by mica, feldspars, chlorite, kaolinite, interstratified and traces of smectite and vermiculite. Semi-quantitative estimation of clay fraction indicated that illite was the single dominant mineral in the clay fraction of these pedons, however, its quantity was less in alluvial plains (28-30 %) compared to Shiwalik hills (36-49 %). Next to illite, a high amount of smectite (14-20 %) and vermiculite (11-17 %) were observed in clays of alluvial plains of Ghaggar (recent and old) whereas in Shiwalik hills (top and valley) these minerals were detected in small amount (6-11 %). Fairly good amount of kaolinite (10-17 %) and small amount of chlorite (4-11 %) were uniformly distributed in soil clays irrespective of geomorphic units showing their detrital origin. Medium intensity broad peaks in higher range diffractograms (14-24 A˚) indicated the presence of regular and irregular interstratified minerals in old alluvial plains of Ghaggar.

“…The soil organic carbon content (SOC) was low in majority of soil samples and it ranged from (0.15-0.90 % Table 1) accounting 644.2 ha (88.7 %) of microwatershed area was low. The low organic matter content in the soils was attributed to the prevalence of tropical condition, where the degradation of organic matter occurs at a faster rate coupled with low vegetation cover, thereby leaving less organic carbon in the soils (Sireesha and Naidu 2013).…”

The present investigation was conducted to know the soil fertility status of Burugamaradoddi microwatershed of Ramanagara district. The soil samples were collected from 0-15 cm soil depth from 70 locations. Soil fertility maps were prepared for pH, electrical conductivity, organic carbon, available nitrogen, available phosphorous, available potassium and available sulphur, exchangeable calcium and magnesium, available boron and available micronutrients viz., iron, manganese, zinc, copper and zinc. Results revealed that the soils were slightly acidic (pH: 5.35-8.32) to moderately alkaline and electrical conductivity of soil were non- saline to slightly saline. The organic carbon status ranged from low to high (0.15-0.90%), and available nitrogen was mostly low. The soil available phosphorus was low to medium; available potassium was in low to medium range and exchangeable calcium and magnesium were found in sufficient range, available sulphur was in low to high range. Regarding available micronutrients, boron and zinc were in low category and level of copper, iron and manganese were in sufficient range. The assessment of soil fertility in Burugamaradoddi micro-watershed revealed that, watershed had better soil fertility status in soil.

“…P1, P3, P4, P5, P6, P7, P8, P9 and P10 were dominated by a hard consistency, however, in P1 and P10 in the subsurface horizon (Bw3 and BC) one could notice a very hard consistency, while in P9 precisely a very hard consistency was found on the surface horizon (Ap). Sticky and plastic consistency might form due to a high clay content in the soil (Sarkar et al, 2001); (Kadao et al, 2003), while non-sticky and non-plastic consistency might form due to a very little clay content (Sireesha, Naidu, 2015;Devi et al, 2015).…”

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.
