Soil Physicochemical Characteristics

Species composition, phytosociological status and soil characteristics of Siwalik forest occurring around Raja-Rani wetland, Letang municipality, eastern Nepal was studied.  A total of 47 tree species belonging to 40 genera and 26 families were reported. Dominant and co-dominant trees were Shorea robusta (IVI=133.4) and Schima wallichii (IVI=70.6), respectively. In the forest total tree density, basal cover area, seedling density, fallen dead density and dead standing density were 378.4 trees ha-1, 163.7 m2 ha-1, 105250 individual ha-1, 4 trees ha-1 and 1.6 trees ha-1, respectively. Irregular girth class distribution and high stump density (136.8 tree ha-1) denote disturbance. Soil physicochemical characteristics were: acidic soil (pH 4.8), moisture (12.5%), water holding capacity (50.05%), bulk density (1.17 g cm-3), porosity (0.55%), humus (8.6%), organic carbon (0.52%), nitrogen (0.1%), phosphorus (33 kg ha-1), and potassium (300 kg ha-1). Regulating human encroachment to ensure natural regeneration of species to maintain the viability of the Letang Raja-Rani wetland site and integrity of the local ecosystem is strongly recommended.

Soil Physicochemical Characteristics

The mountainous massif of Sicó, in the centre of Portugal, is anextensive area composed of calcareous Jurassic formations. Hillsidecalcareous soils, with high pH, present chemical restrictions to supportplant growth and are subjected to important erosion processes leading to their degradation if not protected by vegetation. In a first year of study some soil physicochemical characteristics have been measured in some geo-referenced locations of a larger design experiment and an exploratory spatial analysis has been performed. The objective of this study was to present some suggestions in order to give sustainable phosphorus fertiliser recommendations aiming to establish pastures in these soils and thus support traditional livestock activity. Ten years apart, those soil characteristics have been measured again in the same locations and comparisions have been made. The objective was to understand the variability of the soil properties under study in order to better adequate the fertiliser soil management regarding the area restoration.

Soil Physicochemical Characteristics

ABSTRACTSoils in household environments in low- and middle-income countries may play an important role in the persistence, proliferation, and transmission ofEscherichia coli. Our goal was to investigate the risk factors for detection, survival, and growth ofE. coliin soils collected from household plots.E. coliwas enumerated in soil and fecal samples from humans, chickens, and cattle from 52 households in rural Bangladesh. Associations betweenE. coliconcentrations in soil, household-level risk factors, and soil physicochemical characteristics were investigated. Susceptibility to 16 antibiotics and the presence of intestinal pathotypes were evaluated for 175E. coliisolates. The growth and survival ofE. coliin microcosms using soil collected from the households were also assessed.E. coliwas isolated from 44.2% of the soil samples, with an average of 1.95 log10CFU/g dry soil. Soil moisture and clay content were associated withE. coliconcentrations in soil, whereas no household-level risk factor was significantly correlated. Antibiotic resistance and pathogenicity were common amongE. coliisolates, with 42.3% resistant to at least one antibiotic, 12.6% multidrug resistant (≥3 classes), and 10% potentially pathogenic. Soil microcosms demonstrate growth and/or survival ofE. coli, including an enteropathogenic extended-spectrum beta-lactamase (ESBL)-producing isolate, in some, but not all, of the household soils tested. In rural Bangladesh, defined soil physicochemical characteristics appear more influential forE. colidetection in soils than household-level risk factors. Soils may act as reservoirs in the transmission of antibiotic-resistant and potentially pathogenicE. coliand therefore may impact the effectiveness of water, sanitation, and hygiene interventions.IMPORTANCESoil may represent a direct source or act as an intermediary for the transmission of antibiotic-resistant and pathogenicEscherichia colistrains, particularly in low-income and rural settings. Thus, determining risk factors associated with detection, growth, and long-term survival ofE. coliin soil environments is important for public health. Here, we demonstrate that household soils in rural Bangladesh are reservoirs for antibiotic-resistant and potentially pathogenicE. colistrains and can supportE. coligrowth and survival, and defined soil physicochemical characteristics are drivers ofE. colisurvival in this environment. In contrast, we found no evidence that household-level factors, including water, sanitation, and hygiene indicators, were associated withE. colicontamination of household soils.
