      Effects of Shallow Groundwater Management on the Spatial and Temporal Variability of amounts of surface irrigation impact the extent to which crops will utilize shallow groundwater. Judicious use of deficit irrigation in combination with shallow ground-water management is necessary to achieve optimal re-sults (Ayars et al., ). (See attached Vadose Zone Nitrate Study.) The vadose zone sampling found that to pounds of nitrogen per acre is found in the vadose zone. Due to recharge from over irrigation and rainfall events this nitrogen is moving into the aquifer. Currently another vadose zone study is being completed by UNL to assess the movement and fate.

Nitrate in groundwater is a major concern in agricultural sub-watersheds. This study assessed the impacts of future climate and agricultural land use changes on groundwater nitrate concentrations in an agricultural sub-watershed (Norfolk site) in southern Ontario, Canada. A fully integrated hydrologic model (HydroGeoSphere) was used in combination with the root zone water quality model (RZWQM2.

Impact of Irrigation on the Dynamics of Nitrate Movement in a Shallow Sand Aquifer a. Article. An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).

Groundwater can be extracted using a water study of water flow in aquifers and the characterization of aquifers is called d terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or aquifuge.

In Tunisia, reclaimed water is increasingly used for irrigation in order to mitigate water shortage. However, few studies have addressed the effect of such practice on the environment. Thus, we attempted in this paper to assess the impact of irrigation with reclaimed water on the nitrate content and salinity in the Nabeul shallow aquifer on the basis of satellite images and data from 53 Cited by: 5.

Differences in the impact of irrigation with freshwater versus wastewater on the underlying shallow groundwater quality were investigated in the Coastal Aquifer of Israel.

Seven research boreholes were drilled to the top-most 3–5 m of the saturated zone (the water table. Nitrate reductions for three ground water catchments were 16%, 63%, and 70% of the NO ~ reaching the aquifer.

Nevertheless, the results are a cause for concern because the adverse effects are associated with nitrate concentrations as low as mg/L (5). Relative background concentration of nitrate in shallow groundwaters of the U.S.

is about 1 mg/L (6). Differences in the degree of confinement, redox conditions, and dissolved organic carbon (DOC) are the main factors that control the persistence of nitrate and pesticides in the Upper Floridan aquifer (UFA) and overlying surficial aquifer beneath two agricultural areas in the southeastern US.

Groundwater samples were collected multiple times from 66 wells during – in a study area in. Understanding the nutrient value of nitrate in irrigation water often leads to confusion. Laboratories commonly report nitrate concentration of water samples in parts per million of nitrate (PPM NO 3).However, as shown in Table 1, the reported nitrate value must be multiplied by to express it in equivalents of nitrogen (PPM NO 3-N).This conversion is required because the nitrate molecule.

Study Objectives. Suarez, D.L., Impact of agricultural practices on groundwater salinity. Agric. Ecosystems Environ., The impact of agricultural practices on water quality has been examined predominantly with an emphasis on surface water. Impacts on groundwater, as compared with surface waters, are much.

[1] In arid ecosystems, vegetation controls water and nitrate movement in the soil, reducing solute transport to aquifers. Here we analyzed nitrate distribution and transport throughout the soil profile and to the groundwater under different ecologic (vegetation type) and topographic (upland/lowland) situations across sand dune ecosystems with shallow water tables, subject to Cited by: Somers, G.

Hydrogeology (hydro-meaning water, and -geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers).The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably.

Groundwater engineering, another name for hydrogeology, is a branch. Ground water processes affecting seasonal variations of surface water nitrate concentrations were investigated in an incised first-order stream in an agricultural watershed with a riparian forest in the coastal plain of Maryland.
