“…Water holding capacity showed significant positive correlation with organic carbon content (r=0.55*), silt (r=0.61*), clay (r=0.71**) and mean weight diameter (r=0.82*) and significant negative one with sand (r=-0.92*) (Table 3). These findings are in agreement with those of Gupta et al (2010), Singh et al (2012) and Deb et al (2014).…”

“…The soils under terrace cultivation which have higher pH could be due to rice straw and other organic residues on the terrace which could have prevented serious leaching of bases due to heavy rainfall. Similar results were reported by Sharma et al (2012) and Deb et al (2014) for the soils in some other North-Eastern regions.…”

The study was conducted under three land uses, viz., terrace, jhum and forest to assess the variability of soil properties in Sikhe village under Lower Subansiri district, Arunachal Pradesh. The soil pH was strong to moderate acidic in reaction (pH 4.6 to 6.1). Organic carbon ranged from 10.7 to 46.0 g kg-1 which was found to be highest in forest ecosystem among the land uses. Cation exchange capacity (CEC) ranged between 7.9 and 22.8 cmol (p+) kg -1 and had significant positive correlation with organic carbon (r=0.68**). Bulk density varied from 1.10 to 1.56 Mg m-3, and showed significant negative correlation with organic carbon(r= -0.61*). Bulk density of forest was recorded to be the lowest. Water holding capacity (WHC) varied from 37.0 to 64.2 %, and was found higher under forest land use. WHC had significant positive correlation with organic carbon (r=0.55*) and significant negative one with sand (r=-0.62*). Hydraulic conductivity varied from 0.21 to 1.86 cm hr-1, and was found lowest under terrace land uses. Water stable aggregates (WSA > 0.25) ranged from 83.0 to 96.8 %. Mean weight diameter of the soil varied from 0.52 to 0.88 mm. The textural classes of various soils under different land use systems were loam, sandy loam and silt loam. The dispersion ratio varied from 30.2 to 47.9, which was very high in all the land uses. It had significant positive correlation with sand (r=0.76**) and significant negative correlation with organic carbon (r= -0.74**) and clay (r=-0.56**). Erosion index ranged from 48.1 to 89.9, and the highest was observed under terrace land use and lowest under forest land use. Erosion index had significant positive correlation with sand (r=0.72**) and dispersion ratio (r=0.74**) and significant negative one with organic carbon (r=-0.69**) and clay (r=-0.68**). The dispersion ratio and erosion index of all the land uses were very high indicating that the soils are highly erodible.

“…Likewise, porosity positively correlates with OC (0.57) and K s (0.43). The positive correlation between porosity and OC can be attributed to the higher application of farmyard manure in agriculture in Sikkim and large forest area coverage (Debnath et al, 2012). This is because OC enlarges the macropores in the soil, which in turn results in higher K s , as organic matter retains more water (Nemes et al, 2005).…”

Saturated hydraulic conductivity (Ks) plays a vital role in irrigation and drainage system design. Generally, Ks is estimated in the laboratory; however, it is expensive and tedious, especially in the Himalayan ranges where soil sampling is challenging due to topographical constraints. Therefore, in this study, pedotransfer functions were generated using multiple linear regression (MLR) models for the predictability of Ks in a Himalayan catchment in India. Fifty soil samples were collected and divided into two groups at a 70:30 ratio. Different soil attributes derived from 70% of samples were used for MLR generation, and attributes of the remaining 30% of samples were used for model validation. Six different MLR models constituting different independent soil attributes were generated and compared statistically. The results indicate that the MLR model comprising soil texture, bulk density, particle density, soil moisture content (MC), organic carbon content and porosity results in the highest adjusted coefficient of determination (R2; 0.93 and 0.89 during model generation and validation, respectively). Additionally, it was found that the weight basis MC ranged from 14% to 29% with a median value of 24%. These results demonstrate that simple MLR models can be used as an alternative to laborious experimental setups for Ks estimation. These findings can be used as guidelines for proper irrigation planning and design in mountainous catchments.

“…It gives reasonable information about the capacity of soil to retain water [59]. It powers the plant growth, rooting pattern, and ability to supply water to plants during the dry periods [60]. The average water holding capacity of soil samples in the study area ranged from 53.29±3.82% (M1) to 70.86±2.50% (L2) (F 5, 12 =24.70, p=0.00).…”

The physicochemical properties of soils of six forests varying in elevation (lower, middle, and upper), slope, aspects, and floristic composition viz. L1 (Oak mixed), L2 (Chir pine), M1 (Rhododendron mixed), M2 (Rhododendron mixed), U1 (Abies mixed) and U2 (Abies mixed) from Western Ramganga Valley (Chamoli, Uttarakhand Himalaya, India) were scrutinized. The composite soil samples from three depths (0–10 cm, 11–20 cm, and 21–30 cm) were collected during the different seasons and the physicochemical parameters were analyzed using standard manual and protocol. Texture, bulk density, moisture content, water holding capacity, organic matter, organic carbon, pH, nitrogen content, available phosphorus, exchangeable potassium and C:N ratio of soil samples from each forest site were analyzed and discussed. It was observed that the physical properties of soils either do not vary across the three depths (0–10 cm, 11–20 cm, and 21–30 cm) or show slight changes whereas chemical properties show notable variations comparatively. The significant variation (ANOVA, P < 0.05) was observed in the soil texture (sand, silt, and clay contents), moisture content, water holding capacity, and nitrogen content across the six forest types (study sites). The soil texture ranged between loam and sandy loam which is considered supportive for plant growth. Besides, the lower bulk density and higher soil organic carbon and organic matter with other determined parameters in the studied soils indicate that the studied six forests have sustained nutritive soils. It can be concluded from the present results that the soil physicochemical properties vary with changes in the vegetation composition (forest types) at different elevations in Western Himalaya. Further elaborative study will be done to ascertain interrelationship among the vegetation and soils.
