The implementation of research results. Based on the obtained scientific 
and practical results on the development of scientific bases for the assessment of 
the fertility of irrigated and rainfed soils of the republic: 
"Improved methodological guidelines for the assessment of irrigated soils of 
the Republic of Uzbekistan" introduced in practice in the State Committee on Land 
Resources, Geodesy, Cartography and State Cadastre (Reference of the State 
Committee on Land Resources, Geodesy, Cartography and State Cadastre No. 02-
05-1217 of February 13 2019). As a result, it gave the opportunity to redefine the 
soil bonitet score for 3,648.7 thousand hectares of irrigated lands of farms and 
other land users of the republic and to update land cadastral data; 
"Instructions for conducting soil studies and compiling soil maps for 
maintaining the State Land Cadastre" were introduced into practice in the State 
Committee on Land Resources, Geodesy, Cartography and State Cadastre 
((Reference of the State Committee on Land Resources, Geodesy, Cartography and 
State Cadastre No. 02-05-1217 of February 13 2019). As a result, it served as a 
regulatory document when conducting soil surveys of various sizes and drawing up 
soil maps by the field experts; 
"Improved methodological guidelines for assessing the degree of fertility of 
rainfed soils of the Republic of Uzbekistan" introduced into practice in the State 
Committee on Land Resources, Geodesy, Cartography and State (Reference of the 
State Committee on Land Resources, Geodesy, Cartography and State Cadastre 
No. 02-05-1217 of February 13 2019). As a result, the valuation coefficients made 
it possible to assess the fertility of 6.7 thousand hectares of rainfed soils of the 
Pokhshurd depression in the Sherabad district of the Surkhandarya region; 
soil maps of medium scale (1: 200000) of the mountain-rainfed zones of the 
Jizzakh, Kashkadarya and Surkhandarya regions were put into practice on 
220.1

63 
thousand / ha of Djizak, 258.6 thousand / ha of Kashkadarya and 39.9 thousand / 
ha of Surkhandarya regions (Reference of the State Committee on Land Resources, 
Geodesy, Cartography and State Cadastre No. 02-05-1217 of February 13 2019). 
As a result, they gave the opportunity to develop scientifically based measures for 
the sustainability, protection, efficient use of rainfed soils, and management of 
rainfed land resources; 
“The state of rainfed and pasture lands and recommendations for their 
effective use” was introduced into practice in the State Committee on Land 
Resources, Geodesy, Cartography and State Cadastre (Reference of the State 
Committee on Land Resources, Geodesy, Cartography and State Cadastre No. 02-
05-1217 of February 13, 2019). As a result, they served as a guide in appointing 
measures for the preservation, restoration and improvement, as well as the 
protection of the fertility of rainfed soils of different regions of the republic, the 
efficient use of rainfed land resources on the basis of soil and climatic conditions; 
"Recommendations for the conservation and enhancement of the fertility of 
irrigated soils of farms of the Republic of Uzbekistan" were put into practice at the 
Council of landowners of farmers, dekhkan farms and household lands of 
Uzbekistan (Reference of the Council of landowners of farmers, dekhkan farms 
and household lands of Uzbekistan No. 01/03-431 of February 15, 2019). As a 
result, they served as a scientific basis for assigning agromeliorative, agrophysical, 
agrochemical measures for the preservation and improvement, as well as the 
protection of the fertility of irrigated soils of farms in various regions of the 
republic, the effective use of land resources; 
"The current state of irrigated soils of the Syrdarya region and 
recommendations for the preservation and improvement of their fertility" was put 
into practice in the Syrdarya region (Reference of the Council of landowners of 
farmers, dekhkan farms and household lands of Uzbekistan No. 01/03-431 of 
February 15, 2019). As a result, they gave an opportunity to appoint measures to 
improve the ameliorative state, preserve and improve the fertility of irrigated soils 
of the farms of the region; 
“The main degradation processes in the soils of the Republic of 
Karakalpakstan and recommendations for their prevention” were put into practice 
in soil of the Republic of Karakalpakstan (Reference of the Council of landowners 
of farmers, dekhkan farms and household lands of Uzbekistan No. 01/03-431 of 
February 15, 2019). As a result, they served as a guide to farms in improvement of 
ameliorative condition, preservation and restoration of fertility of the degraded 
soils of the Aral Sea region; 
recommendations on the state of the soil of the Republic of Karakalpakstan, 
Andijan, Namangan and Fargana, Bukhara, Jizzakh, Navoiy, Samarkand, Syrdarya, 
Tashkent, Kashkadarya and Surkhandarya, Khorezm regions, additionally on 
agrotechnologies for placing and growing crops on low-fertile lands were 
introduced in the system of Ministry of Agriculture (Reference of the Ministry of 
Agriculture No. 02/020-140 of 6 March 2019). As a result, they gave an 
opportunity to assign measures to reduce the degradation processes formed in 
various soil and climatic conditions of the republic, in particular, to preserve, 
restore and improve the fertility of low-fertile and low-productive soils, as well as 
the placement of highly profitable crops.
