Land application of coalbed natural gas (CBNG) co-produced water is a popular management option within northwestern Powder River Basin (PRB) of Wyoming. This study evaluated the impacts of land application of CBNG waters on soil chemical properties at five sites. Soil samples were collected from different depths (0-5, 5-15, 15-30, 30-60, 60-90, and 90-120 cm) from sites that were irrigated with...
One of Iraq's most significant groundwater-bearing limestone aquifers is the Dammam Formation. The aquifer groundwater has been studied hydrogeochemically. It suitable for irrigation, as indicated by sodium adsorption ratio (SAR) and total dissolved solids (TDS), which are 4.15 1971 ppm (in average) respectively. Through vision Stiff diagram, predominant ions Cl-, SO42+ Na+ while HCO-3 Mg2+ rel...
Water resources are of great importance in the world's agriculture, especially regarding scarcity these resources. That calls for attention appropriate analysis, study, and research all issues aspects that would contribute to development maintenance those achieve maximum possible levels quality efficiency use. The study was conducted during fall season 2020 groundwater (well water) city Al-Qaim...
Groundwater in the Touggourt region—or as its named, Oued Righ—in southeastern Algeria, is only source of irrigation. To assess suitability for agricultural purposes, we collected 72 samples from wells at this region, physical and chemical measurements were carried out each water sample, calculations sodium adsorption ratio (SAR), permeability index (PI), soluble percent (SSP), residual carbona...
one of the main aims of water resource planners and managers is to estimate and predict the parameters of groundwater quality so that they can make managerial decisions. in this regard, there have many models developed, proposing better management in order to maintain water quality. most of these models require input parameters that are either hardly available or time-consuming and expensive to...
The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...
Increased population and increasing demands for food in the Indo-Gangetic plain are likely to exert pressure on fresh water due rise demand drinking irrigation water. The study focuses Bhojpur district, Bihar located central Ganga basin, assess groundwater quality purpose discuss issues challenges. Groundwater is mostly utilized area purposes (major crops sown rice wheat). There were around 45 ...
An investigation was conducted to evaluate the water quality of some ground for irrigation, drinking and livestock consumption. Fifteen samples were collected from Babugonj upazila of Barisal district in Bangladesh. The chemical constituents of water samples were determined to find out their suitability for irrigation, drinking and Livestock consumption. As per pH all water samples were slightl...
Considering the impacts of agricultural runoff, domestic and industrial effluents on quality many dams rivers as cited in literature, a physico-chemical study regarding water assessment Ghunghuta dam has been carried out to indicate irrigation suitability water. In present study, parameters like pH, EC, TDS, TH, Ca, Mg, Na, K, carbonate bicarbonate were estimated evaluate sodium percentage (% N...
