Goychay region has very suitable and unique lands for strategic agroecological monitoring. A dry steppe and semi-desert zone, which is characterized by a pronounced arid climate, is located at an altitude of 200–400 m above sea level, where the dominant soils in the territory are various subgroups of gray-brown soils and serozem types. The fact that soil studies in the Goychay region of the Azerbaijan Republic are less studied than in other regions, and there is no literature, is an innovative and urgent problem for soil scientists. The article presents some of the results of seasonal surveys, ecological expertise and biological diagnostics carried out in recent years. Biological diagnostics, environmental monitoring and assessment of these soils by modern methods are of great innovative importance for the development of agriculture in Azerbaijan. As a result of many years of agroecology research, the involvement of natural cenoses in agriculture has created conditions for obtaining high productivity from these soils

Modern Methods

The application of modern methods of time-series analysis to a record of sea-level variation at Flint Cliff, Hamelin Pool, between October 1983 and April 1985, shows that astronomical tides account for only one of the following five key components of the record: a seasonal oceanic cycle; a short-term irregular cycle; the complex astronomical tidal system in the Pool; isolated major events; and less marked variations probably reflecting wind stress, still able to defeat the astronomical tide in the short-term. We have compared the inundation record with precisely surveyed elevation ranges of various microbial communities. The dominance of a seasonal cycle is the fundamental determinant of variation in the duration of immersion and exposure determining the littoral zonation of microbial mats in Hamelin Pool. The astronomical tide is not the major cause of this variation. The microbial communities fall into three zones. In Zone 3, the microbialite-forming colloform mat is virtually never exposed. In Zone 2, smooth, reticulate and mamillate mats colonise the lower littoral environment. Here, many of the exposed microbialites have been stranded by the falling sea level, and are colonised by intermittently submerged microbial communities that modify the stranded lithified microbialites. Zone 1 is inundated only under exceptional circumstances and microbial communities are ephemeral.

Pemupukan merupakan salah satu input faktor pada perkebunan teh yang terus mengalami pening­katan harga. Penurunan biaya pokok dapat diupayakan melalui peningkatan efisiensi dan efektivitas pemupukan. Tanaman teh dapat tumbuh dan berproduksi dengan baik pada ketinggian minimal 700 meter di atas permukaan laut. Seiring pertumbuhannya, tanaman teh juga mem­butuhkan ta­naman pelindung untuk membantu dalam pengurangan evaporasi, mengurangi froze, sebagai wind brea­ker, dan juga sebagai sumber bahan organik. Pada masa Tanaman Belum Menghasilkan (TBM), tanaman pelindung yang dipakai adalah tanaman pelindung sementara yang merupa­kan tanaman Legu­minosa dan bersimbiosis dengan Rhizobium sp. yang dapat memfiksasi nitrogen dari udara dan menghasilkan fitohormon IAA sebagai biokatalisator yang dapat memper­cepat pertumbuhan tanaman. Setiap tanaman Leguminosa bersimbiosis dengan Rhizo­bium sp. yang spesifik dan berbeda-beda pada satu jenis tanaman dan ketinggian tempatnya. Oleh karena itu, perlu dilakukan penggalian potensi alam lokal yang terdapat pada daerah tanaman teh dataran tinggi, khususnya Rhizobium sp. dari tanaman Leguminosa yang merupakan pohon pelindung tanaman teh. Tujuannya adalah agar diperoleh karakter spesies Rhizobium sp. dataran tinggi yang pada tahap penelitian selanjutnya dapat dimanfaatkan untuk meningkatkan kesuburan tanah, meningkatkan produktivitas tanaman, dan akhirnya dapat mengop­timalkan biaya pemupukan pada perkebunan teh. Dari penelitian diperoleh enam spesies Rhizobium sp. dari perkebunan teh dataran tinggi yang diberi kode YA, YB, YC, YD, YE, dan YF. Secara makroskopis terdapat perbedaan pertumbuhan Rhizobium sp. tersebut dengan pertumbuhan tercepat adalah Rhizobium sp. dari tanaman pelindung sementara Tephrosia sp. dan Seisbania sp. pada perkebunan teh. Fertilization is one of input factors on tea plantation that is increasing on the price. The decreasing of the main cost can be done by increasing the efficiency and effectiveness of fertilizing. Tea plant can be grown with high productivity at least at 700 m above sea level. Along with the growth, tea plant need shade tree to eliminate evaporation and froze, and act as a wind breaker and organic material source. Leguminose plants used on young tea is a symbiotic plant with Rhizo­bium sp. This microorganism can fix Nitrogen from the air, and produce fitohormone such IAA functioning as bio-catalist to accelerate the plant growth. Every Leguminose plant has specific symbiosis with Rhizo­bium sp. depending on plant species and elevation. Furthermore, there is a need of exploration of the indigenous Rhizobium sp. from Leguminose shade tree at highland tea plantation. The aim was to get species characteristic of Rhizobium sp. that can be used for the next research to increase soil fertility, plant productivity, and opti­mize the fertilizer cost on tea plantation. The result found six species of Rhizobium sp. with code YA, YB, YC, YD, YE, and YF. Macroscopically, there were differences on the characteristic among them. The highest rate of growth were found for Rhizobium sp. from Tephrosia sp. and Seisbania sp. temporary shade trees on tea plantation.

Under the scope of the scheduled activities of the Kalmyk Scientific Center of the RAS there are complex works including archaeological excavation works of the new archaeological sites – Bashanta I and Bashanta II settlements of the Khazar Khaganate era, and also the exploration of the monuments that are often out of the focus of research. This refers to the sites that have once been excavated and left without further special investigation and publications. Alongside with the urgent need for the introduction of the sites excavated in the last century and their further additional comprehensive research using the modern methods and publications, there is no less urgent problem of the exploration of the archaeological sites that have not been excavated, explored and recorded in the state register. The recording, describing, documenting and including these sites to the list of protected objects of cultural heritage is the guarantee of their preservation. The authors of the article have been conducting systematic research in this field. The given article deals with the results of the study of the mound group Ut Sala that includes 171 mounds.

Parameter Approach

The Marnes Bleues Formation from the Vocontian Basin (Southeastern France) shows many organic rich levels, some concomitant to oceanic anoxic events OAE1a and OAE1b. These organic-rich levels are scattered through a thick homogeneous succession of marls, poor in organic matter (OM). Through a multi-parameter approach, the organic-rich levels from the Aptian-Albian were characterized. Our results show that all OM-rich levels exhibit variable characteristics, such as OM nature (marine vs. continental), sedimentation and accumulation rates, redox conditions, surface-water productivity and relative sea level, but they all show low to modest enrichments in OM. Furthermore, all the levels share in common the fact that they formed under conditions of normal to low productivity and oxic to suboxic conditions. Thus, our results strongly suggest that, in the absence of high productivity and anoxic bottom conditions, the other factors reputed to favor OM accumulation only led to sporadic and low enrichments in organic contents. It is as if such factors could only enhance OM accumulation but could not induce it alone. What was true for the Vocontian Basin may be extended to other settings, regardless of their time of deposition or location.

The distribution of Hexatoma (Eriocera) ussuriensis Alexander is analyzed on the basis of the authors' original material and the specimens kept in the collection of the Zoological Institute, St. Petersburg (including the types). Diagnostic characters of H. ussuriensis are summarized. H. ussuriensis is recorded for the first time from Mongolia, Japan and eastern Siberia (including new records from five provinces of Russia: Kemerovo Province, Republic of Altai, Krasnoyarsk Territory, Irkutsk Province, and Buryatia). The known distribution of this species is wide; it ranges from ca. 61° to 43°N, from 30 to 650 m above the sea level, and covers different landscape-climatic zones (from boreal forest to dry steppe). Records of H. ussuriensis are confined mostly or entirely to different-type running waters, which probably serve as larval habitats. They are briefly characterized and illustrated. Adults of H. ussuriensis were for the first time reared from larvae collected in the Chikoi River (Buryatia, Russia).

Given the acceplance, in the high valleys of Mexico -2200 to 2600 mts. over sea level-, of free-pollination strains and the high productivity of hybrids, we considered the alternative of combining these frec-pollination strains with the H-34, thus obtaining another experi-mental single hybrid and our goal was to determine its potential productivity level. The strains known aas Ixtlahuaca, Santiago Yeche and Acambay improved from 37,3% to 20,8% their productivity when crossed with H-34, such was not the case with the strains Almoloya de Juarez and V-23. The other single hybrid was named 417, and it led to aHigher productivity in Ixtlahuaca with 29.1%. When we conbined H-33 x 417 it yielded 9728 kglha, a 7% higher than that of 9088kg/ha with H-33. The results of VS-22x 417 were very similartothose with VS-22. The results indicated that we could use H-34 and perhaps other single hybrids in combination with free-pollina-tion strains, thus obtaining a certain level of heterosis and facilitating seed production, but based on the different responses, this should beevaluated previous to any combination be performed.

The article presents the results of field observations over 2012–2018 carried out by the Department of Environmental Research of the Institute for Complex Studies of Arid Territories. The work includes materials on the climatic review and the original results of geobotanical investigation of 5 farms in rural municipalities of the Republic of Kalmykia (RK) over the period of the study. We used materials of a large geobotanical survey of YUZHNIIGIPROZEM Company (1991–1995) and materials of earth remote sensing (by Landsat satellite). According to the studies, the period from 2012 to 2018 demonstrates a general trend of climate warming throughout the territory of Kalmykia accompanied by a decrease in precipitation and an increase in extreme droughts in the summer. Geoecological monitoring of pastures at five key sites of the RK revealed that in the dry steppe zone (Manych municipality) and in the semi-desert zone (Khanatinsky municipality), deterioration of pastures is observed; in the desert zone (Adykovskoye municipality), significant degradation processes were identified associated with strong anthropogenic impact and fires, manifested in the loss of valuable food crops (wormwood) and increased influence of cereal crops. Floristic and phytocenotic analyzes revealed an increase in the number of plant species in the weed and ruderal groups.
