“…Between 2017 and 2020, the difference in seed yield and dry hay of alfalfa between unfertilized plots (T1) and fertilized plots (T4, T5) further increased, and a significant difference was observed between the T1 and T4 treatments (Figure 3). These findings corroborated the results of other studies that reported a positive influence of P and N on alfalfa yield even in soils (Markus and Battle, 1965;Kafkafi et al, 1977;Barbarick, 1985;Macolino et al, 2013;Yertayeva et al, 2019).…”

Article InfoIn Turkestan region of South Kazakhstan has large areas of fertile sierozem soils that are important for crop production and its accompanying economic development. And also, alfalfa (Medicago sativa) is an important forage crop grown for seed production. The soils are fertile loams, but because of the regions dry environment, they need to be irrigated. Field experiments were conducted from 2017 to 2020 on one-year or older alfalfa stands grown for seed production at various plots on sierozem soils in rainfed areas of Turkestan region to determine the influence of agricultural practices such as fertilizer use, pesticide use and conventional tillage on seed yield and dry hay of alfalfa stands. The findings of field research experiments indicated that agricultural practices of fertilizer use, pesticide use and conventional tillage was essential to obtain maximum seed yield and dry hay of alfalfa. But, it was determined that the best outputs tended to be obtained with Fertilizer use + Pesticide use + Conventional tillage.

“…A close dependence of the content of mobile phosphorus on the amount of excrement was found in August (r = 0.75). Bioindicators are often used as sensitive indicators of soil fertility under different land use systems and the degree of its degradation due to anthropogenic factors (Schwilch et al, 2016;Bünemann et al, 2018;Yertayeva et al, 2019). Biological diagnostics of soils is an important component of both local and global monitoring.…”

A comparative study of ecological and biological parameters of soils of the Rostov-on-Don Zoo was carried out in 2017-2020. Monitoring sites were studied in areas of various purpose: aviaries with different animals, recreation area, park area. The control plot was a relatively undisturbed park section in the territory of the zoo. Different sites revealed heterogeneity of ecological conditions and soil properties. The most significant difference was in the physical properties of soils. Density, penetration resistance, and soil structure were degraded in aviaries with large animals: rhinos, zebras, deer. Using methods of bioindication, the degree of change in the soil of aviaries was determined compared with the soil of the control plot. The abundance of nitrogen-fixing bacteria of the Azotobacter genus was reduced in the soils of aviaries with zebras, rams, rhinos and giraffe due to the artificial addition of sand to the soil for the purpose of improvement of its physical properties. The activity of soil enzymes (urease and dehydrogenases) was significantly increased in the soils of aviaries due to their contamination with animal excretory products. A particularly high increase was in urease (up to 7.4 times relative to the control soil). The main problems of the topsoil of the zoo are overconsolidation, structural degradation, organic pollution, change in biological activity. The degree of change depends on the size of aviaries, the size and activity of animals and soil amelioration aimed at regulating physical properties of the soil.

“…Saline-sodic soils are found across various continents, ranging from tropical to polar zones, but they are most common in the Northern Hemisphere. In the Commonwealth of Independent States (CIS), the area covered by saline-sodic soils amounts to 120 million hectares, and the escalating expansion of these soils has made their reclamation a prominent concern in modern soil science (Yertayeva et al, 2019). Kazakhstan, a country located mostly within the largest drainless part of the plain, faces an uneven distribution of saline soils.…”

“…Crop losses due to sodic salinity in these areas range from 15% to 45% (Funakawa et al, 2000;Saparov, 2014;Pachikin et al, 2014;Otarov, 2014;Laiskhanov et al, 2016;Suska-Malawska et al, 2019;Zhang et al, 2019;Ma et al, 2019;Yertayeva et al, 2019;Kussainova et al, 2020;Liu et al, 2022;Suska-Malawska et al, 2022). Peasant farms annually apply various agricultural practices, from plowing to harvesting, to address salinesodic soil patches.…”

This study presents the combined findings of laboratory experiments conducted to assess the efficacy of various ameliorants on saline-sodic soils in the foothill plain of Ile Alatau in the Northern Tianshan region. The investigation focused on the influence of phosphogypsum, elemental sulfur, nano sulfur, and sulfuric acid on the ionic composition of the soil solution and their impact on the soil-absorbing complex. Different doses of these ameliorants were applied to saline-sodic soil samples, and their incubation period was observed. The analysis of the aqueous extract of the soil emphasized the presence of bicarbonate, carbonate, sulfate, calcium, and sodium ions. The results revealed that sulfuric acid was the most effective ameliorant, rapidly neutralizing extreme alkalinity, reducing bicarbonate and carbonate ion content, and increasing sulfate and sodium ion concentrations. Elemental sulfur ranked second in effectiveness, significantly decreasing bicarbonate and carbonate ions and increasing sulfate and sodium ions. Phosphogypsum exhibited the lowest effectiveness, causing reductions in bicarbonate and carbonate ions and modest increases in sulfate and calcium ions. The study demonstrated that the introduction of phosphogypsum led to an increase in calcium and sulfate ions in the soil solution, while elemental sulfur and sulfuric acid significantly increased the sulfate ion content. Sulfuric acid exhibited the highest efficacy among the ameliorants, completely neutralizing normal carbonates and reducing alkalinity in the soil solution. The formation of subsoil gypsum through the interaction of sulfuric acid with calcium carbonates facilitated the displacement of sodium from the soil-absorbing complex. These findings contribute to our understanding of the processes involved in the amelioration of saline-sodic soils and provide insights into effective soil management practices. They serve as a theoretical basis for developing strategies for the reclamation of such soils worldwide. The research highlights sulfuric acid as the most effective ameliorant for saline-sodic soils, resulting in a significant rearrangement of the soil's ionic composition. Further research and field studies are necessary to validate and refine these laboratory findings for practical applications in soil improvement methods.
