“…Obviously, in this case, it is necessary to take into account the complexation processes of iron and manganese with organic ligands of soil solutions. Soil solutions and surface waters differ significantly for individual groups of soils, soil and climatic conditions, and for individual geochemical provinces [1,3,5,9,11]. This determines their different biological activity and the effect on the biological activity of stimulants and inhibitors dissolving in them, fertilizers and ameliorants, the geophysical fields of the Earth, and magnetic fields created.…”

“…For comparison, the analysis took soddypodzolic medium-loamy soils of varying degrees of hydromorphism on cover loams. The research methodology consisted of assessing pH, Eh, the activity of K, NO3, NH4, Ca, Mg by generally accepted methods, assessing the concentrations of water-soluble compounds extracted from soil by ion exchange membranes, and assessing the biological activity of solutions using biotests [3,[6][7][8][9].…”

Soil solutions and the surface waters are characterized by properties, processes and regimes. Soil solutions of different soils and their surface water have different biological activity and change the activity of dissolved stimulants and inhibitors. The object of the study are soil solutions of the main types of soils obtained in the model experiments with the ratio of soils: water equal to 1:1 and 1: 2, soil solutions and surface water in the flooding of soils with water for 1 week – 3 months. The research method consisted in the assessment of pH, Eh, activity of K, NO3, NH4, Ca, Mg by conventional methods, assessment of concentrations of water-soluble compounds extracted from soils by ionite membranes, in the assessment of biological activity of solutions using biotests. The following is suggested for additional evaluation: the using of cation and anion membranes, determination of interrelation between the properties of waters, equation of pair correlation and multiply regression. The informative value of the gradient of surface water concentrations at different distances from the floor of the reservoir, at different depths of the overwatered soils is shown. The mobility of Ca, Mg, Fe, Mn in soils and the content of their water-soluble forms depends on both pH and Eh, whose influence on the content of water-soluble forms of the considered cations shows the effects of synergy and antagonism. The rate of change in the composition of soil solutions during soil flooding depends on a combination of soil properties, temperature, and duration of flooding. Soil solutions of different soils and their surface waters have differentrates.

Problems Of Sustainable Management Of Water Resources Of Lake Sevan And Its Basin

Numerous rivers, lakes and other water features have suffered significant alterations as a result of human economic activity. As a result, hydrometric, hydrological, biological, ecological conditions, as well as morphometric elements of these objects were violated. In this regard, Lake Sevan and its basin might be used as a well-known example. There has never been any instance in the history of limnology where a lake’s level was artificially lowered by 18 meters over 3 to 4 decades (1930–1970), and by another 2 meters at the end of the 20th century (1990–2000). Additionally, the lake’s water volume dropped from 58 billion m3 to 32 billion m3. The Sevan problem first surfaced in the late 19th and early 20th centuries and is still a problem today. However, it has many meanings/soundings at different times. Based on this, we usually divided the entire study period into several stages. It should be noted that the ecosystem has suffered irreparable losses as a result of the use of the Lake Sevan resources, inadequate water resource management, and both positive and negative effects of these factors. We disagree with the assertions of many experts that problems can only be prevented or solved by raising the lake level. Therefore, extensive actions must be taken in the Sevan basin management area, regardless of the lake’s level.

This article discusses the impact of artificial lowering of lake water level on water ecosystems using the case study of Lake Sevan. Numerous rivers, lakes and, in general, water bodies have undergone considerable changes under the impact of the economic activity of man. As a result, hydrometrical, hydrological, biological, ecological conditions as well as the morphometrical elements of these bodies have been destroyed. Lake Sevan and its basin may serve as a classical example in this respect in the world limnology, there has been no other case when a lake level would be artificially lowered by 18 meters for 3-4 decades (1930-70 s), and by another 2 meters at the end of 20th century (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000) and the volume of water in the lake decreased from 58 billion m3 to 32 billion m3. it must be noted that the drop of the lake level, and the economic development in the basin brought about the change in the hydrological regime of the lake. The latter caused the disruption of the hydro chemical and hydrobiological regimes of the lake. The quality of the water deteriorated; water turbidity increased. The inner circulation of the water substances, as well as the circulation of the biological substances altered as well.
