ABSTRACT 

Soil properties can vary to some extent depending on the geomorphological conditions in which they are located. This 

is due to the diversity of parent rocks, layering and mechanical composition of the soil. The article presents and 

compares the properties of irrigated gray-meadow, meadow and marsh-meadow soils located on terraces I, II, III of 

the Syrdarya River. Based on the results obtained, recommendations are given for the rational placement of plants. 

 

KEYWORDS 

Terrace, proluvial, alluvial, loess deposits, ground water level, soil salinity, mechanical composition, humus, nitrogen, 

phosphorus, potassium, dry residue, sulfate, chlorine. 

 

INTRODUCTION 

Scientists from different countries have published 

scientific data on changes in soil properties depending 

on the geomorphological position. However, the data 

obtained differ depending on the unique natural and 

climatic conditions of the regions.

In the researches of Y.Wang, Y.He, J.Zhan, Z.Li [1], it 

was determined that the spatial structure of soil 

particles is different depending on the location of the 

terrace of the river bank. He compared the properties 

of soils distributed in the foothills, central alluvial 

plains, and eastern coastal plains. According to the 

geomorphological conditions of the soil distributed on 

the river bank, the mechanical composition of the soil 

determined the distribution of sand, sand, loam and 

clay particles. 

According to E.A.Batrachenko [2], soil properties 

mainly depend on the parent rocks that form the soil. 

The strength of anthropogenic impact on soil 

properties also directly depends on the 

geomorphological conditions of the soil. The different 

topography of the Kurs region has a direct impact on 

erosion processes. It is noted that the ecological 

conditions of soils located in different 

geomorphological conditions are also different. 

G.V.Dobrovolsky, P.N.Balabko, N.V.Stasyuk, 

E.P.Bykova [3] gave information about the specific 

characteristics and properties of alluvial soils. It has 

been proven that the soils of the river banks have high 

biogenicity and intensive soil formation processes. 

N.A.Shaporina, A.V.Chichulin [4] and 

M.V.Konyushkova, B.D.Abaturov [5] studied the effect 

of microrelief on the hydrothermal condition of the soil 

cover. It is noted that the hydrothermal conditions of 

the soils located below in terms of microrelief are rich 

in moisture and relatively cold.  

S.S.Gudimovich [6] expressed his opinion on the 

location, naming and description of river terraces. He 

gave a description of soil properties depending on the 

location of each terrace, analyzed the data of various 

scientists. The location schemes of the terraces and 

information on their description are presented. 

L.A.Yablonsky [7] provided information on the history 

of studying the soils of river banks. As a result of the 

soil being constantly wet, the process of glaciation 

occurred. This was also shown in the morphological 

characteristics of soils. As a result of the gliding 

process, the structure of the soil is disturbed, and the 

number of useful microorganisms decreases. 

Studies have been conducted on the different 

properties of the soils located in different parts of the 

Mirzachol oasis and the changes in the soil as a result 

of human activities. It was noted that the properties of 

the soils in the old and newly developed parts of 

Mirzachol differ from each other [8-13]. 

Research methods. Special experiments were 

conducted to study the properties of soils located on 

different terraces of the Syrdarya River. For this, “key 

sites” were selected from the areas located on the I, II 

and III terraces of the river. When choosing these 

areas, they tried to be typical for this terrace. Soil 

cuttings were placed on selected “key sites”. Soil 

morphological features were studied and compared. 

Soil samples were taken from soil sections and 

analyzed. Soil granulometric composition, total humus, 

nitrogen, phosphorus, potassium, mobile phosphorus 

and potassium, water absorption were analyzed.  

Results and discussions. In order to study the 

properties of soils located on different terraces of the 

Syrdarya river, two massifs in Gulistan district were 

selected: massifs named “Boyovut” and “Uch 

Qahramon”. Below is information about the 

description and mechanical composition, agrochemical 

parameters of the soils located on the river terrace of 

these massifs. 

It consists of newly irrigated marsh-meadow soils 

located on the upper terrace I of the Syrdarya,

The mechanical composition of the soil consists of 

medium and light sand. The thickness of the humus 

layer is 60 cm, the amount of humus in this layer is 

1.40%, the amount of mobile phosphorus is 15.2 mg/kg 

in the 0-30 cm layer, and 8.5 mg/kg in the 30-50 cm 

layer, and exchangeable potassium is 220 in the 0-30 

cm layer. In the 30-50 cm layer, it is 50 mg/kg. The 

density is average. There is no clay layer. The level of 

ground waters is 255 cm. 

If one pays attention to the sections located on 

different terraces of the Syrdarya, first of all, one can 

see the difference in the depth of seepage waters in 

them. In the cross-section located on the I-terrace of 

the Syr Darya, the level of seepage water is higher, 

while in the cross-section located on the III-upper 

terrace, it is about 2.5 meters. Correspondingly, the 

depth of meeting the gley layer also differs. 

Also, soil agrochemical properties have different 

indicators in three sections. The amount of total 

nitrogen in section 26 is relatively higher than other 

sections. This is related to the humus and nitrogen 

content of grassland soils. The amount of total 

phosphorus and potassium was distributed almost 

uniformly in all three soil sections. But the indicators of 

the 3 sections differ from each other in terms of the 

amount of mobile phosphorus. It is 7-8.5 mg/kg in cut 

26, which is very low. This is related to the process of 

soil grazing. The soil located on the second and third 

terraces has a relatively higher index in the sections. 

The amount of mobile phosphorus is low in grassy soils 

due to the fact that the binding force of phosphorus is 

intensive. 

CONCLUSIONS 

The experiment found that the properties of soils 

located in the same area, but located on different river 

terraces, are also different. These differences are 

primarily manifested in the morphological features of 

the soil. Meadow soils are relatively darker in color 

because they are richer in humus than other soils. Due 

to constant moisture, gleying is observed, as a result of 

which a bluish gley layer forms on the soil profile. In 

addition, differences in the mechanical composition of 

the soil, salinity and agrochemical parameters can be 

observed. Given the above, it is recommended to plant 

moisture-loving plants on the soil of the I-terrace of the 

river.
