There are analyzed results of long-term researches on the use optimization of forage soils transformed by bushes in the south of the country. Classification of agro forestry lands of the Volga-Akhtuba floodplain of the Astrakhan region, overgrown with silver berry Elaeagnus angustifolia was made on the bio productive potential. Rational methods of nature management and effective measures on improving the zoo ecological comfort of the transformed landscapes were developed. Field studies have established the ecological-ameliorative role of silver berry plantations gion.

The livelihood of the Himalayan people depends on rangeland-based livestock farming in Nepal. Above 2500 m altitude, the contribution of rangelands to livestock feed supply is more than 65%. Rangeland comprises about 11.5% of the total land resources of Nepal and over 98% are located in high mountains and Himalayan regions. Nepal is rich in biodiversity, with over 6500 species of flowering plants, including 180 species of grasses and legumes.

The scientific journal was founded in 1951. The journal presents the results of research and practical advice on the issues of land reclamation and use of reclaimed lands. The journal is included in the list of scientific editions of the Republic of Belarus for the publication of results of dissertation research.

The agricultural lands have a special legal regime and are subject to the protection aimed at limiting the seizure of these lands, preserving and increasing their fertility. The area of lands of this category in the structure of land Fund accounts for 100.8 million hа, or 38.6% of used land. Their share in the land Fund of the regions ranges from 70-75% (North-Kazakhstan, Akmola region) to 10-20% (Kyzylorda, Atyrau region). It is mainly related to different climatic conditions and vast areas of desert and semi-desert rangelands.

In this article features of potential of agrarian sector of economy in modern conditions are considered. Theoretical and methodological basis of research were the works of domestic and foreign scientists on the investigated problem, dissertation abstracts, National Sustainable Rural Development Program for 2011-2015 and etc. The main components of resource potential are de-fined and the directions promoting its development in the conditions of globalization are allocated.

The major natural factors negatively impacting the properties of solonetzes of the northern forest-steppe of Baraba Steppe were found and stability of the meliorandscapes of the steppe including reclaimed solonetzes was defined. The field research was done in 2006-2016. Cortical hydromorphic solonetzes, reclaimed by gypsum in 1986 in four replications, were studied. The following variants of the experiment were compared: control (without gypsum), 11, 45 and 65 t/ha. Till 1996 cereal crop rotation was cultivated, and in 1996 meliolandscape was abandoned.

In the Western region of Ukraine, melioration is both of economic and social importance. The area of reclaimed lands constitutes 2.2 million ha or 24 % of the total agricultural lands in the region. Thus, melioration is of great importance for social-economic development of agro-industrial complex of the territory. Under conditions of the land reform in Ukraine, reclaimed lands were subjected to sharing and privatization causing a negative impact on efficiency of its utilization and technical conditions of the reclaimed land infrastructure.

The influence of application of various soil ameliorants (lime, manure and phosphorus fertilizers) to increase fertility of extremely acid soil type Pseudogley was investigated. The greatest fertility increase of studied soil was obtained by combined use of lime, manure and complex NPK fertilizer. In this variant, pH value, content of easy – available P and available Ca increased for 2.0pH units, 3.5 mg 100 g-1 and 39 mg 100 g-1 , respectively in relate to control sample.

Preventing contamination of natural waters and controlling the volume and improving the quality of drain and wastewater from the reclaimed territories of the Non-Chernozem Zone of Russia requires applying a set of measures as well as developing new technical solutions.

In a course of the research there were described the methodological approaches to optimization of the use of resources allocated for the operation of melioration systems and the use of reclaimed land. As a result of realized research there was estimated theoretical and actual productivity of reclaimed land in Gorki and Kalinkovichi districts of the Republic of Belarus with the proposed economic and mathematical model.
