The present study was aimed to investigate the effect of physico-chemical parameters and soil macro-nutrients to know the nutrient uptake status during sowing time (ST) and after the harvesting (AH) of crops of Leh-Ladakh. In this context, total 55 no. of soil samples were collected from the eleven villages. Thereafter, soil texture, pH, electrical conductivity (EC), total dissolved solids (TDS), organic carbon (OC), nitrogen (N), phosphorus (P), and potassium (K) were analyzed as per the standard methods. The results exhibited variation in different studied parameters at ST and AH, are OC (ST- 1.70 ± 0.11; AH-2.31±0.08), N (ST- 171.54±11.40; AH- 212.03±13.18), P (ST- 75.62±8.16; AH- 96.32±11.56), pH (ST- 8.12±0.05; AH- 8.16±0.06), EC (ST- 0.48±0.04; AH- 0.58±17), TDS (ST-309±22.41; AH-189±16.42) and soil texture gradient (Sand: ST-75.16±1.27 & AH-71.75±1.26, Silt: ST- 18.55±1.09 & AH- 20.66±1.02 and clay: ST- 6.33±0.53 & AH- 7.76±0.63). The comparison of physico-chemical parameters, macronutrients, soil texture, and organic carbon at sowing time (ST) and after harvesting (AH) revealed significant difference in some macronutrients, EC, and organic carbon, whereas no changes were observed in soil texture, pH and phosphorus. Hence, this study highlights the need of physico-chemical parameters management during crops sowing for enhancing macronutrients availability to crops in trans-Himalayan high altitude region.

This work focuses on analyzing of physico-chemical properties of sediment affected by frequent floods along the eastern shore of the Bandama River in the department of Niakaramadougou. Sampling was from 4 excavated graves at two positions of studied area, one near the stream and the other one far away from the stream.. Samples collected were analyzed, including texture with granulometric analysis made by the Robinson pipette, and standard sediment analysis methods for measuring organic carbon (OC), nitrogen (N), and other chemical properties including pH, organic matter (OM), and C/N ratio. Statistical analyses were carried out to assess the differences between the physico-chemical parameters at different sampling areas. Differences are significant when comparing areas that are highly affected by floods and areas that are less affected by floods, especially for concentrations of OM, OC and nitrogen. Results show that successive floods are influencing directly the dynamic of physico-chemical properties of the sediments along the shore.

This study examines the distribution of organic matter in areas affected by frequent floods along the east bank of the Bandama River in the department of Sinématiali. The sites sampled are defined by two zones, one near the stream and one far from the stream. Samples collected were analyzed, including for texture with aggregation analysis by the Robinson pipette, and standard sediment analysis methods for measuring organic carbon (CO), nitrogen (N), and organic matter (MO). Statistical analyzes were carried out to assess the differences between the physico-chemical parameters of the different sampling areas. Results show that sediment from the various study sites has a sando-limonous to limono-clay texture. Total organic matter levels are higher in surface sediments that contain the lowest proportions of clay. Rates range from 31.98 gkg-1 to 38.98 gkg-1. In depth, the rates obtained are very low and range from 6.3 gkg-1 to 8.193 gkg-1. The low rates recorded in depth are reported to be related to leaching caused by periodic flooding. These results show that successive floods have a direct effect on the dynamics of the physico-chemical properties of the sediments along the shore.

We investigated the effect of origin and some physico-chemical parameters on the kinetics of reduction with hydrogen of two series of mixed NiO-Fe2O3 oxides differing by their composition, the character of their precursors (mixed crystalline nitrates and coprecipitated hydroxides) and their decomposition temperature.This effect manifested itself by different magnitudes of specific surfaces of the mixed oxides and coherent regions of present phases as well as by different oxidizing abilities of the surface and differences in morphology and phase composition of corresponding samples in both series investigated. Nonlinear or nonmonotonous composition dependences of physico-chemical parameters investigated point to a mutual influence of individual components, which is also a function of the system origin and which modifies its reactivity during its reduction with hydrogen. The kinetics of the reduction was studied thermogravimetrically at 320-410 °C. The reduction of oxides of the hydroxide origin is catalytically accelerated by primarily reduced nickel, whereas in corresponding samples of the nitrate series, the total NiO is bound to the spinel phase and the reduction is delayed. Experimental IR spectra, the effect of preliminary annealing and DTA of the mixed oxides point to an inhibitory effect of water, which is constitutionally bound in trace admixtures of the goethite phase, on the kinetics of reduction of samples in the hydroxide series.

The study aimed to develop a non-dairy-based probiotic-supplemented product using an underutilized crop in the Philippines such as the yellow passion fruit (Passiflora edulis f. flavicarpa Deg.). The physico-chemical properties (moisture content, water activity, pH, and total soluble solids), probiotics stability at different storage temperatures (4°C, 25°C, and 37°C), and the sensory characteristics of Lactobacillus plantarum S20-supplemented passion fruit juice powder was evaluated. Passion fruit juice powder and L. plantarum S20 were first prepared using low-temperature spray drying utilizing maltodextrin as a carrier, with yield as 42.97% and 21.17%, respectively. Spray drying of probiotics culture also resulted in 42.68% log survivability. The formulated juice powder had a final moisture content of 1.729±0.38% and water activity of 0.398±0.0051, and with recommended dilution with water, had a final pH and total soluble solids of 3.40±0.10 and 12.00±0.00° Brix, respectively. Results also showed that storage of the formulated juice powder at 4°C yielded the highest probiotic stability, maintaining a viable log count of 4.27 per g, while storage at 37°C showed no microbial growth. Sensory evaluation of probioticsupplemented passion fruit juice against a non-probiotic-supplemented one revealed significant difference in terms of color, sweetness, and sourness, while no significant difference was observed in terms of aroma, mouthfeel, and general acceptability.

This study examined the effect of deforestation on the soil properties (physico-chemical and bacterial) of the Sal (Shorea robusta Roxb. Ex Gaertn.) forests in Bangladesh. Physico-chemical properties and the bacterial colony counts of soil were studied by comparing a natural Sal forest site with deforested and planted with Menjium site, deforested and planted with Mahogoni site, as well as deforested but not planted but covered with profuse growth of Axonopus compressus grass species site. Moisture content was significantly lower in the deforested and planted with Menjium site and deforested and planted with Mahogoni site than the natural forest site and the deforested but not planted site. Total organic carbon, total nitrogen and available nitrogen contents were significantly lower in the natural forest site. Significantly higher number of bacterial colony and higher organic carbon and moisture contents were found in the deforested but not planted site indicating that both organic carbon and moisture content were important for microbial growth. The present study clearly showed that deforestation significantly altered the soil physico-chemical and bacterial communities of the Sal forests. It was also revealed that plantation with different exotic plants were found to be different in influencing soil properties.

The Impact

The objective of this study was to evaluate the impact of different land use systems on soil erosion rates, surface evolution processes and physico-chemical properties on a moraine hilly topography in Lithuania. The soil of the experimental site is Bathihypogleyi – Eutric Albeluvisols (abe–gld–w) whose texture is a sandy loam. After a 27-year use of different land conservation systems, three critical slope segments (slightly eroded, active erosion and accumulation) were formed. Soil physical properties of the soil texture and particle sizes distribution were examined. Chemical properties analysed for were soil ph, available phosphorus (P) and potassium (K), soil organic carbon (SOC) and total nitrogen (N). We estimated the variation in thickness of the soil Ap horizon and soil physico-chemical properties prone to a sustained erosion process. During the study period (2010–2012) water erosion occurred under the grain– grass and grass–grain crop rotations, at rates of 1.38 and 0.11 m3 ha–1 yr–1, respectively. Soil exhumed due to erosion from elevated positions accumulated in the slope bottom. As a result, topographic transfiguration of hills and changes in soil properties occurred. However, the accumulation segments of slopes had significantly higher silt/clay ratios and SOC content. In the active erosion segments a lighter soil texture and lower soil ph were recorded. Only long-term grassland completely stopped soil erosion effects; therefore geomorphologic change and degradation of hills was estimated there as minimal.
