Himalayan regions have increasing sediment yield due to undulating topography, slope and improper watershed management. However, due to limited observation data, and site accessibility issues, less studies have quantiBed sedimentation loads in the Himalayas, especially Nepal. This has hindered the investments on run-of-river hydropower projects as ...

Abstract—A study was conducted with the purpose of comparing the efficiency of ammonium acetate (NH4OAc), Mehlich 3 (M-3), Calcium Chloride (CaCl2) and alpha MIR spectroscopy measurement, for the determination of available potassium (K) on 58 Ethiopian agricultural soils. Four soil reference groups were sampled for the study. The NH4OAc extractant ...

Artemisinin extracted from Artemisia annua has been used efficiently in malaria treatment since 2005. In this study, the variations in plant parameters (plant biomass, glandular trichome density, essential oil total chemical content, artemisinin production, and polyphenol oxidase (PPO) activity) were tested under different soil types (Luvisol, Gley...
Mozambique is characterized by low agricultural productivity, which is associated with low use of yield-enhancing agricultural inputs. Fertilizer application rate averaged 5.7 kg ha-1 in Mozambique during the period 2006 to 2015, considerably low by regional targets, yet constraints that affect fertilizer use have not been thoroughly investigated. ...
Study region: Karnali-Mohana (KarMo) river basin, Western Nepal. Study focus: This study has developed a hydrological model using multi-site calibration approach for a large basin, the Karnali-Mohana (KarMo) in Western Nepal, which has a lot of potential for water resources development and contribute to the national prosperity. It further applies t...
The aims of this study were to analyze the spatial distributions of, contamination statuses of, and factors contributing to, heavy metals in cropland areas of different cities / thus, 55 agricultural soils were collected from 12 cities of Shandong Province, China. Concentrations of copper (Cu), lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni) an...

BackgroundEvaluation of surface runoff is an essential factor in the precision water and soil conservation management through their main extreme impacts on soil properties. The natural resource conservation service curve number model (NRCS-CN) model is used to estimate the magnitude of runoff. Collected topographic data is used to explain the effec...

The aim of the paper was to present the correlation between soil types specified in the sixth edition of the Polish Soil Classification (SGP6 2019) and Polish bonitation classification. The comparisons included two categories of agricultural land: arable soils and soils of permanent grasslands. In Poland bonitation maps are one of the oldest docume...
