The Republic

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

Labor Potential

Scientifically substantiated personnel industry policy contributes to the implementation of an innovative development scenario, provides better results with reduced production costs, which determines the relevance of the studying. The main goal of the work was identified factors and indicators which have regulatory influence on the state and development of the personnel potential of the industry. Diagnostics of the labor potential of land reclamation by federal districts revealed leaders and outsiders of sectoral development. The studying made it possible to justify the steady trend of the shortage of reclamation personnel in comparison with the calculated indicators. Objective and subjective reasons and factors that hinder the effective using of the industry’s personnel potential are distinguished. The concept of industry’s labor potential is clarified. The studying of changes in labor productivity in agriculture has confirmed a twofold increasing in this indicator for the period from 2014 to 2018. Methodological approaches to the indicators of assessing the labor potential of the reclamation industry are substantiated. The groups of socio-economic indicators of the reclamation industry’s effectiveness are identified. The methodology for determining the quantitative characteristics of labor potential on irrigated lands is specified, which is depended on the area of irrigated lands. The labor potential of the reclamation industry in terms of staffing the industry is studied. The main positive and negative trends of the personnel policy and the labor potential’s formation of the agro-industrial complex’s reclamation sector of the Russian Federation are specified, the industry personnel policy is assessed as passive, which does not allow predicting the needs for industry personnel, evaluate staff activities and analyze personnel problems. Highlighted characteristic trends in personnel potential in the federal district and regions of the Russian Federation allow: to develop unified approaches to manage this industry development factor; to develop recommendations to improve the efficiency of advanced training and retraining of personnel in irrigated agriculture. The implementation of the recommendations will contribute to increase the efficiency of the managing the human potential’s process of irrigated agriculture at the level of federal, regional and municipal authorities of the reclamation sector of the agro-industrial complex of Russia.

Meteorological Droughts

Droughts are one of the primary natural disasters that affect agricultural economies, as well as the fire hazards of territories. Monitoring and researching droughts is of great importance for agricultural disaster prevention and reduction. The research significance of investigating the hysteresis of agricultural to meteorological droughts is to provide an important reference for agricultural drought monitoring and early warnings. Remote sensing drought monitoring indices can be employed for rapid and accurate drought monitoring at regional scales. In this paper, the Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation indices and the surface temperature product are used as the data sources. Calculating the temperature vegetation drought index (TVDI) and constructing a comprehensive drought disaster index (CDDI) based on the crop growth period allowed drought conditions and spatiotemporal evolution patterns in the Volgograd region in 2010 and 2012 to be effectively monitored. The causes of the drought were then analyzed based on the sensitivity of a drought to meteorological factors in rain-fed and irrigated lands. Finally, the lag time of agricultural to meteorological droughts and the hysteresis in different growth periods were analyzed using statistical analyses. The research shows that (1) the main drought patterns in 2010 were spring droughts from April to May and summer droughts from June to August, and the primary drought patterns in 2012 were spring droughts from April to June, with an affected area that reached 3.33% during the growth period; (2) local drought conditions are dominated by the average surface temperature factor. Rain-fed lands are sensitive to the temperature and are therefore prone to summer droughts. Irrigated lands are more sensitive to water shortages in the spring and less sensitive to extremely high temperature conditions; (3) there is a certain lag between meteorological and agricultural droughts during the different growth stages. The strongest lag relationship was found in the planting stage and the weakest one was found in the dormancy stage. Therefore, the meteorological drought index in the growth period has a better predictive ability for agricultural droughts during the appropriately selected growth stages.

For satisfactory growth, most high-value hardwood species demand a deep, fertile, moist but well drained soil. Intensive competition control during the early years after planting is a necessity. Close spacing is recommended, with gradual release of crop trees to promote high-quality stem development. For good hardwood growth on soils of marginal fertility or poor drainage or on sites where intensive management cannot be guaranteed, it is recommended that a mixture of several hardwood species be planted.

At present, the study of natural objects without modern information technologies is almost impossible. The use of GIS for monitoring spatial features of irrigation systems uncovers broad opportunities. The development of the organizational structure, the selection of the necessary software tools for the collection, storage, processing and analysis of semantic data integrated with spatial objects is an urgent task and has important scientific and practical value. The irrigated lands located in the southeast of Kazakhstan within the Almaty region are the object of research. Monitoring of these land salinization is carried out, including hydrogeological and hydrological observations and soil reclamation studies. The article discusses the methodology for creating a geographic information and analytical system to monitor irrigated lands, and describes its organizational structure. The content of the database, the composition of functional components, the basic properties and capabilities of laboratory processing and analyzes of field materials are described. The cartographic material component describes its basic properties, including properties intended for analysis of database objects and their spatial point analogues. Also, the possibilities for ArcGIS application modules to automate the process of constructing maps of the hydrogeological and reclamation conditions of irrigated objects, and the possibilities for automated calculation of areas in specified gradations of depth and groundwater salinity to assess the reclamation state of these lands are shown.
