This study was designed to investigate the effects of different tillage systems on some parameters such as soil salinity (pH, EC, SAR), soil density and nutrients in a nested experimental design with three treatments (no tillage, reduced tillage and conventional tillage) and three replications. Chenaran city fields were selected as the case study areas. Result of the statistical analysis indica...

Ramanathapuram is a drought-prone southern Indian district that was selected for conducting hydrogeochemical study. Groundwater samples from 40 locations were collected during January 2020 (pandemic interdiction according to COVID) and 2021. The properties of the groundwater evaluated compared with drinking water regulations assess their quality. order cation dominance as follows: Na+ > Ca2+...

Groundwater resources along with surface-water meet the needs of urban, industrial, and agricultural sectors, therefore, their quality should be examined. Water indices are useful tools for aquifer management. In this research, groundwater Miandoab Plain in province West Azerbaijan, northwest Iran, purposes was investigated. For purpose, concentrations ions Mg2+, Ca2+, Na+, HCO3−, SO42−, Cl− pH...

Water quality monitoring is crucial in managing water resources and ensuring their safety for human use environmental health. In the Al-Jawf Basin, we conducted a study on Quaternary aquifer, where various techniques were utilized to evaluate, simulate, predict groundwater (GWQ) irrigation. These include indices (IWQIs), geochemical modeling, multivariate statistical analysis, geographic inform...

the study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and na+, mg2+, ca2+ uptake of pistachio seedling (akbari) grown under salt stress.  a completely randomized design was used with four replications in greenhouse conditions. the experimental treatment consisted of four levels of humic acid (bis humic) (0, 4, 8 and 12 gr k...

Erosion is one of the most destructive and continuous phenomena that cannot be prevented and only could be controlled by studying the chemical and physical properties of soil. Marls are one of the most important sedimentary units in Iran which have high rate in sediment production and erodibility because of their Physico-chemical characteristics. These properties caused large environmental and ...
