“…This may have affected soil conductivity and moisture regulation. The soil's electrical conductivity increases as a result of silica absorbing cations from the soil medium, particularly Ca, mg, and K. These cations function as carriers of electrical current in the soil [60]. Silica was applied to increase the strength of the barley by thickening the cell walls, with the aim of preventing lodging [61].…”

Precise adjustments of farm management activities, such as irrigation and soil treatment according to site-specific conditions, are crucial. With advances in smart agriculture and sensors, it is possible to reduce the cost of water and soil treatment inputs but still realize optimal yields and high-profit returns. However, achieving precise application requirements cannot be efficiently practiced with spatially disjointed information. This study assessed the potential of using an electromagnetic induction device (EM38-MK) to cover this gap. An EM38-MK was used to measure soil apparent electrical conductivity (ECa) as a covariate to determine soil salinity status and soil water content θ post irrigation at four depth layers (Hz: 0–0.25 m; Hz: 0–0.75 m; Vz: 0.50–1 m). The inverse distance weighting method was used to generate the spatial distribution thematic layers of electrical conductivity. The statistical measures showed an R2 = 0.87; r > 0.7 and p ≤ 0.05 on correlation of ECa and SWC. Based on the South African salinity class of soils, the area was not saline ECa < 200 mS/m. The EM38-MK can be used to estimate soil salinity and SWC variability using ECa as a proxy, allowing precise estimations with depths and in space. These findings provide key information that can aid in irrigation scheduling and soil management.

The aim of the study was to assess the groundwater quality in a rural area affected by the abandoned pyrite ash waste dumps. The abundance of major ions in groundwater depends largely on the nature of the rocks, climatic conditions, and mobility. To evaluate geochemical processes, 30 groundwater samples collected from Valea Calugareasca, Prahova County, Romania, were analyzed for the major anions (NO3−, SO42−, Cl−, HCO3−, and F−) and cations (Ca2+, Mg2+, Na+, and K+), which are naturally highly variable due to climatic and geographical location conditions. Ca2+, Na+, Mg2+, and K+ varied between 118 and 275 mg/L, 32 and 160 mg/L, 12.2 and 78.4 mg/L, and 0.21 and 4.48 mg/L, respectively. NO3− levels exceeding the World Health Organization (WHO) limit of 50 mg/L were identified in 17% of the groundwater samples, mainly as result of fertilizers applied to agricultural activities. The hydrogeochemical study identified dolomite dissolution and halite precipitation as natural sources of ions as well as the presence of pyrite as a source of SO42− ions in 60% of the samples. The sulfate content varied between 125 and 262 mg/L. Bicarbonate and chloride concentrations varied between 202 and 530 mg/L and 21 and 212 mg/L. The saturation index indicates the contribution of Ca2+ ions in the groundwater samples came from some processes of dissolving rocks such as aragonites (values between 1.27 and 2.69) and calcites (values between 1.43 and 2.82). Negative halite values indicated that salt accumulation results from precipitation processes. Only 10% of the analyzed groundwater samples were suitable for human consumption, the samples being situated on the hill, far away from the pyrite ash waste dumps and agricultural land.

Surface water is an indispensable water resource of drinking and irrigation, which plays important role on human health and quantity of grain production. Hydrogeochemical process as well as quality assessment of 31 representative surface water samples from 3 typical lakes around Fuli abandoned quarries area were carried out. The cation is dominated by Ca 2+ and Mg 2+ , while the anion is dominated by HCO 3 and SO 4 2-. The two leading hydrochemical type are SO 4. HCO 3 -Ca.Mg (100%) in No. 1 lake, wheres HCO 3. SO 4-Ca.Mg (88.24%) and SO 4. HCO 3 -Ca.Mg (11.76%) of No.2 and No.3 lake. The chemical composition of No.1 lake are mainly controlled by carbonate dissolution and ion-exchange, the chemical composition of No.2 and No.3 lake is mainly influenced by both ion-exchange and dissolution of carbonate and silicate minerals, among which rock weathering is the most important factor. The recharging of the lakes is mainly derived from atmospheric precipitation with the existence of evaporation. The surface water in the study area, in general, is suitable for drinking and irrigation. The outcomes of this research provide a better understanding of hydrochemical mechanism of surface water around quarries, and it will help to improve management and sustainable utilization of water resources for local government.
