INTRODUCTION

RELEVANCE AND NECESSITY OF THE TOPIC 

The reasons for the origin of saline soils, including salt 

marshes, are very diverse. One of them, and the most 

important, is the host rocks, which are distributed in 

dry climatic conditions and contain various types of 

salts. Salty rocks, especially sea sediments, come out 

close to the surface of the earth for various reasons, 

which causes soil salinization. Such salt deposits are 

widespread in the Pamir, Hisar mountain ranges, 

Fergana and Bukhara lowlands. In addition, the 

geomorphology of the place determines the 

redistribution of water, as well as salts dissolved in it, 

in horizontal and vertical directions. As a result, it 

affects the active movement of soil and water-soluble 

salts. As a result, it affects the active movement of soil 

and water-soluble salts. Salt accumulates more in the 

high and low areas of the field than in the flat parts. The 

presence of macro- and micro-reliefs causes spotty 

salinization. Salt spots vary in shape, size, and 

appearance. It can make up 10-12% of the total area of 

spotted salt marshes. 

Saline soils on the territory of the Republic of 

Uzbekistan are located in Syrdarya, Jizzakh, Bukhara, 

Navoi, Khorezm regions. It is widespread in the

Republic of Karakalpakstan, Karshi desert, Surkhan-

Sherabad steppe, Central Ferghana and other places. 

The flowing waters of the globe have a great influence 

on the amount and composition of salts in the soils and 

seepage waters of the river valleys. The mineralization 

of river water and its chemical composition depend on 

the following: from the upper part of the river to the 

lower part, the salinity of seepage water and soil 

increases, and the amount of chlorine, sodium, and 

magnesium in the salts gradually increases. 

Saline soils on the territory of the Republic of 

Uzbekistan are located in Syrdarya, Jizzakh, Bukhara, 

Navoi, Khorezm regions. It is widespread in the 

Republic of Karakalpakstan, Karshi desert, Surkhan-

Sherabad steppe, Central Ferghana and other places. 

vegetables and other agricultural products are rarely 

obtained. 

THE OBJECT AND SUBJECT OF THE RESEARCH 

The main source of salt formation is rocks that are 

disintegrating due to weathering. During weathering, 

a large amount of carbonates are formed due to the 

combination of various salts with chlorides, sulfates, 

nitrates, silicates, and especially carbon dioxide. Ca, Na, 

H, Mg are the majority in the cations of salts. Al, Fe, 

trace elements are also partially found. Salts flowing 

from the surface of the earth and seepage are 

transferred to the oceans or closed basins on land, 

which are considered the final destination, and 

accumulate there. 

Highly saline soils always produce lower yields than 

non-saline soils. At the same time, they require more 

labor and resources from the government and farmers. 

In the history of irrigated agriculture, there are cases 

where the yield was so low as a result of the high 

salinity of the soil that the costs of growing crops were 

not justified. Such lands were found to be unusable and 

were not used for planting crops. There were even 

more cases where they started to take over newly 

saline or even non-saline lands for irrigated crops, but 

their intensive salinization occurred during irrigation. 

Viable land has become unusable and is often not used 

for irrigated crops, resulting in many crop fields, 

drylands, and other vacant land among the old 

irrigated land. 

The radical destruction of the natural environment 

caused by uncontrolled irrigation has determined the 

change of hydrogeological, geochemical and soil 

processes and creates the necessary conditions for the 

increase of secondary salinity, as well as the 

desertification of the area. Taking a large amount of 

water for irrigation has sharply reduced the flow of 

Syrdarya and Amudarya waters to the Aral Sea, as a 

result of which its level has decreased (by 16 m), soil 

salinity has increased (from 10-12 to 30-35 g/s). As a 

result of the lowering of the water level of the Aral Sea, 

its bottom was opened, intensive deflation and 

removal of salts from the surrounding areas began. 

The development of secondary salinity and the 

deterioration of environmental conditions have also 

contributed to the deterioration of groundwater and 

river water quality due to increased drainage flow. This 

led to increased mineralization of waters, their 

contamination with pesticides. The poor quality of 

drinking and irrigation water has affected the quality of 

products, human health, and the state of natural and 

anthropogenic ecosystems. 

Secondary salinity in often irrigated soils even in 

relatively deep groundwater (3.5-4) at microrelief 

elevations, seasonal (summer) spotted salinity in 

irrigated fields free from cultivated plants begins to 

appear in the form of This form of seasonal 

manifestation of secondary soil salinity is not always

noticeable due to its ephemeral character and 

relatively little damage to cultivated plants. However, 

seasonal salinity causes damage to cultivated plants, 

resulting in reduced yield and quality. The danger of 

seasonal soil salinity is that once it occurs and dies, it 

can develop into a patchy permanent form of salinity. 

CONCLUSION 

Seasonal salinity is relatively easy to overcome with 

amelioration and agrotechnical methods, thereby 

reducing groundwater and evaporation. Leveling of 

the earth's surface, careful watering and mechanical 

processing of crops during the growing season, paying 

special attention to cultivated plants in the fields, and 

using alfalfa in crop rotation play an important role.
