Study of Longtime Soil Formation on Overgrown Quarry on the South of Kazakhstan 11 января, 2017

Long-term researches of soil-formation process on reclamate freshly exposed loess are conducted by soil permanent study area of Agriculture University which is situated in Kastanozem soils zone in the foothills of Ile Alatau. Soil permanent study area consists of 72 concreted plots measuring 2 m2. They were filled with loess to a depth of 60 cm in the spring of 1991. Quantity of long studied variants is 5, one of them has natural undisturbed profile of Kastanozem. There is also variant with loess filled in 1971. Different doses of ameliorants were applied and phyto-improvers were seeded on variants, which were filled from 1991. In 1994-1995 test sowing were made and from 1996 it was left as neglected field. According to the research of 1991-2012 years, it was established, that calcium cation is predominant in composition of absorbed bases. Its content of total cations has increased from 66% to 82% after 18 years (1991 -2009) of pedogenenic process. The highest rates of exchange capacity and calcium content in absorbed bases are set on variants Natural Kastanozem, Loess, since 1971, Phytocontrol, Vermicompost, 27 ton ha-1. This confirms the dominant role of the time factor and the reclamation of syngenetic pedogenenic process. Gradual increase of the exchange capacity (from 13.55 to 20.18 meq 100 g-1) in time was established for explored variants. pH on loess in the 0-point of pedogenenic process was 8.2, and it was 7.8 after 21 years of pedogenenic process.

Ecological-faunistic Review of the Geometrid Moths (Lepidoptera, Geometridae) of Northern Tien-Shan Mountains 13 января, 2017

The present study was carried out between 2009 and 2014 in Northern Tien-Shan Mountains, with the aim of assessing the fauna of geometrid moths (Lepidoptera, Geometridae) and collecting data on the distribution and ecology of the species. New faunistic data are given on 129 species, out of which 56 species are new records for Northern Tien-Shan. Two species of the genera Thera and Horisme may be new for science. Larentiinae (57 species) were the most diverse subfamily, as it is typical for mountainous regions. The second most diverse were the Ennominae (35 species), followed by Sterrhinae (28 species) and Geometrinae (nine species). The vast majority of the recorded geometrids are mesophilic, followed by xerophilic and xero-mesophilic elements. A small number of species are ubiquists.

Its content of total cations has increased from 66% to 82% after 18 years (1991 -2009) of pedogenenic process. The highest rates of exchange capacity and calcium content in absorbed bases are set on variants Natural Kastanozem, Loess, since 1971, Phytocontrol, Vermicompost, 27 ton ha-1. This confirms the dominant role of the time factor and the reclamation of syngenetic pedogenenic process. Gradual increase of the exchange capacity (from 13.55 to 20.18 meq 100 g-1) in time was established for explored variants. pH on loess in the 0-point of pedogenenic process was 8.2, and it was 7.8 after 21 years of pedogenenic process. The highest content of hydrolyzable nitrogen, after variant Natural Kastanozem (57.9 mg kg-1) is established on variants: Loess since 1971y. (38 years) – 44.9 mg kg-1; Vermicompost, 27 ton ha-1 (18 years) – 43.0 mg kg-1; Manure, 60 ton ha-1 (18 years) and Phytocontrol (18 years) – 41.6 mg kg-1. The same variants (13 years) – 30.8-39.2 mg kg-1. The same variants (3 years) – 16.8 mg kg-1. Then and there, the content of hydrolyzable nitrogen in replantosols depends on the duration of pedogenenic process and types of bioreclamation. Content of labile phosphorus in replantosol does not particularly depend on pedogenenic process and varies from 13.0 to 19.6 mg kg-1. Maximum content of exchange and water-soluble potassium is observed in the upper horizon of r replantosols, it gradually decreases with depth. Exchangeable potassium content was low in the initial 3 years with fluctuations within 204,1-217,1 mg kg-1. For 13 years and 18 years, their number stabilizes at 384-403.8 mg kg-1. Content of mobile nutrients for 2009 shows that the best conditions for plant nutrition is observed on variants Loess since 1971, Vermicompost, 27 ton ha-1. Key words: Physical and chemical absorbing power, nutrient status, soil formation, reclamation, loess, replantosols, vermicompost.

The level of soil contamination with heavy metals in Almaty Kazakhstan 13 января, 2017

Almaty is the largest metropolitan city in Kazakhstan and is included among the most important financial, cultural and scientific centers of Central Asia. During the recent years, because of the high rate of urbanization and increasing traffic flow, the issues concerning the detrimental effect of the automobile transport on the megalopolis environment becomes particularly important. Several studies were carried out in this area, which have suggested ways to solve the problem. Though, the soil of the megalopolis, as an integral environmental component, and the level of its contamination by heavy metals (pollutants) is investigated still insufficiently. Therefore, we have conducted studies to determine the level of soil contamination with heavy metals. The research has shown that the amount of heavy metals in the soil of Almaty does not yet exceed permissible limits, though their amount in the soil continue to grow.

Advances in Eco-Efficient Agriculture: The Plant-Soil Mycobiome 16 февраля, 2017

Abstract: In order to achieve a desirable ecological and sustainable agriculture a thorough understanding of the plant-soil mycobiome is imperative. Commercial industrial agriculture alters greenhouse gas emissions, promotes loss of plant and soil biodiversity, increases pollution by raising atmospheric CO2, and releases pesticides, thus affecting both terrestrial and aquatic ecosystems. Diversified farming systems, including perennial cultivated pastures, are among worldwide strategies that aim to reduce terrestrial greenhouse gas emissions and deal with threats to global sustainability. Additionally, stimulation of soil microbes and appropriate soil management can influence soil interactions as well as the rates of organic matter decomposition and the release of gases. Agricultural soil microbial communities play a central role in ecosystem processes and are affected by biocontrol agents, biofertilizers, and exposure to pesticides, the extent to which is yet to be fully elucidated. Intercropping different plant species is beneficial, as this can increase carbon fixation by plants, transferring carbon to the soil, especially via mycorrhizas, thus modifying interplant interactions. This review focuses on agro-ecosystems, showing the latest advances in the plant-soil interface (the mycobiome) for an eco-efficient agricultural production.
