“…We assume the exchange mechanism is at a local thermodynamic equilibrium since determining the sodium cation in the soil solution and the sodium cation in the exchange complex [ 106 ] requires the application of the well-known Gapon equation [ 102 ]. This was in agreement with the study of [ 107 , 108 ], who noted that a significant amount of exchangeable Na was released because of the chemical substitution between the cations in the treatments and the Na + in the soil exchange site. The explanation for this could be that gypsum provides soluble Ca 2+ directly to replace exchangeable Na.…”

Background: Sodic soils are harmful to agricultural and natural environments in Ethiopia’s semi-arid and arid regions, leading to soil degradation and reduced productivity. This study investigated how amendment resources could help improve the chemical properties of sodic soils around the Abaya and Chamo Lakes in the South Ethiopia Rift Valley. Methods: A factorial experiment was conducted to study the effects of gypsum (GYP) and farmyard manure (FYM) on sodic soil reclamation. The experiment had four levels of GYP (0, 50, 100, and 150%) and four levels of FYM (0, 10, 20, and 30 tons ha−1), with three replications. The pots were incubated for three months and leached for one month, after which soil samples were collected and analyzed for chemical properties. ANOVA was performed to determine the optimal amendment level for sodic soil reclamation. Results: The study found that applying 10 ton FYM ha−1 and gypsum at 100% gypsum required (GR) rate resulted in a 99.8% decrease in exchangeable sodium percentages (ESP) compared to untreated composite sodic soil and a 1.31% reduction over the control (GYP 0% + FYM 0 ton ha−1). As a result, this leads to a decrease in soil electrical conductivity, exchangeable sodium (Ex. Na), and ESP values. The results were confirmed by the LSD test at 0.05. It is fascinating to see how different treatments can have such a significant impact on soil properties. The prediction models indicate that ESP’s sodic soil treatment effect (R2 = 0.95) determines the optimal amendment level for displacing Ex. Na from the exchange site. The best estimator models for ESP using sodic soil treatment levels were ESP = 1.65–0.33 GYP for sole gypsum application and ESP = 1.65–0.33 GYP + 0.28 FYM for combined GYP and FYM application, respectively. Conclusion: The study found that combined GYP and FYM applications reduced ESP to less than 10% in agriculture, but further research is needed to determine their effectiveness at the field level.

Disparities in pH, conductivity, organic carbon (OC), nutrients, and moisture between the Asan Wetland and its periphery in the Western Himalaya, India, highlight the need to investigate influencing factors. This study thus addresses two gaps: (1) identifying key drivers for alkaline pH and elevated wetland concentrations and (2) understanding how different values outside the wetland relate to ecological processes. Asan Wetland soil samples, collected on April 15, 2023, underwent analysis for pH, electrical conductivity (EC), organic carbon (OC), organic matter (OM), available nitrogen (N), available phosphorus (P), potassium (K), sodium (Na), calcium (Ca), moisture content (M), total organic carbon (TOC), and total organic matter (TOM) using standard laboratory procedures, APHA, CPCB, and standard manual techniques. Within the wetland, results indicated that the soil is more alkaline (pH 8.50 ± 0.13) than the periphery in the concentrations of EC, N, K, and M were found to be higher compared to the corresponding concentrations outside the wetland, with mean values of 1.10 ± 0.15 ds/m, 364 ± 117.13 kg/ha, 86.42 ± 21.64 kg/ha, and 20.87 ± 1.50%, respectively. Conversely, outside the wetland, higher values of OC, OM, P, Na, Ca, TOC, and TOM were recorded (0.39 ± 0.23%, 0.66 ± 0.39%, 0.82 ± 0.35 ppm, 80.45 ± 8.46 ppm, 268.12 ± 61.12 ppm, 56.80 ± 0.33%, and 97.70 ± 0.57%, respectively). pH, EC, K, Ca, Na, and moisture content variations indicate location‐based differences. pH, TOM, TOC, and soil moisture were positively correlated within wetlands but negatively correlated with Na and N. In addition, moisture was positively correlated with pH and N but negatively correlated with Ca, K, Na, and P. The study concluded that the Asan Wetland exhibits distinct soil characteristics compared to its periphery, exhibiting location‐based differences while emphasizing these factors' interconnectedness.
