The biological activity of the arable layer of farmland depends on the physico-chemical properties of plant protection products used in agriculture, and also determines the behavior of xenobiotics in soil. We have investigated the degradation of herbicides preparations depending on soil properties. Ranking techniques was investigated the influence of independent factors (the content of the clay fraction and humus, pH, CEC, etc.) On the dependent variable (the change of the rate of decomposition of the herbicide - k). The result set different contribution of soil conditions on the degradation of the active substances in the soil herbicide formulations (Table. 1). For imidazolinone herbicides observed binding activity of their protonated molecules soil absorbing complex, regardless of the content of humus in acidic soil. Indicator for sorption imazamox ranged Kd = 1,5-2,4, and in neutral or alkaline soils not exceed Kd = 0,5-0,8. For imazethapyr regardless of the acidity of the soil and humus content index Kd ranged 0,08-0,76 and determines the differences in the mineralogical composition of the soil. Found high rates of sorption for atrazine, imazethapyr and other herbicides in the case of worsening of the mechanical composition of the soil (clay mineral content greater than 42%). In general, increasing the rate of degradation studied herbicides (benzoic acid derivatives tiadiazinony, sulfonylureas, imidazolinones, chloroacetamides) associated with the value EKO, humus soil and silt. So, especially the influence of different factors on the degradation of herbicides in agro-ecosystems is important to know. With the right choice of adaptive strategies of agriculture can reduce environmental risks in the system of soil-herbicide.

С помощью метода денатурирующего градиентного гель-электрофореза амплифицированных фрагментов 16S рДНК эубактерий (праймеры 341F и 907R) оценили генетическое разнообразие бактериального сообщества в образцах почвосубстратов, отобранных на территории нефтяных скважин Западной Сибири (Тюменская область, Ханты-Мансийский автономный округ) и загрязненных нефтью и буровыми отходами. Даже в крайне загрязненных почвах, содержащих 50-100 мг нефтепродуктов в грамме, обнаружено по меньшей мере 15 доминантных видов бактерий. В целом по всем изученным образцам количество выявленных полос ДНК не коррелировало с уровнем загрязнения анализируемого субстрата. Также не обнаружено одинакового для всех исследованных образцов доминантного штамма. Не выявлено ни одного образца с абсолютно уникальным составом бактериального сообщества; всегда присутствовали компоненты, характерные, как минимум, еще для одного образца. Проведенные исследования еще более подчеркнули актуальность детального изучения биоразнообразия почвенных экосистем нашей страны, так как понимание закономерностей формирования его состава и структуры сообществ почвенных микроорганизмов является необходимым для поддержания здоровья окружающей среды и населения.

The textbook is recommended for the univesities students for the course "Biology of the Soils".

Effect of environmental pollution with a cationic surface-active substance on algae and Fagopyrum esculentum sprouts. – The Soviet Journal of Ecology [ISSN 00967807; later the journal was entitled: Russian Journal of Ecology]. 1990. Vol. 21. No.2, p. 79-81. http://scipeople.com/publication/70248/ 3 tables. Bibliogr. 10 refs. [in collaboration: Ostroumov S.A., Tret’yakova A.N. ). [At that moment of time the journal was published by Plenum Publishing Corporation, 233 Spring St., N.Y., N.Y. 10013; the reference number of the publication published at the first page of the paper: 0096-7807/90/2102-0079]. The effects of environmental pollution with a cationic surface-active substance (surfactant tetradecyltrimethylammonium bromide TDTMA) on certain cyanobacteria and algae - cyanobacteria Nostoc muscorum Ag, strain 33 isolated from the soil in the Kirov Oblast (Region); green algae Bracteacoccus minor (Chodat) Petrova, strain 200 and strain 219 (the strain 219 was isolated from the volcanic ash collected next to Tyatya Volcano, island of Kunashir) - was investigated. Their sensitivity to that surfactant TDTMA was compared with the sensitivity of a test based on the use of terrestrial plants. The algal experiments were performed with aquatic and soil cultures. The experiments with terrestrial plants used the earlier-developed method with seedlings of Fagopyrum esculentum Moench. TDTMA at concentrations 1 mg/L and above produced some negative effects on cyanobacteria and algae in aquatic cultures. TDTMA at concentrations 50 mg/L and above produced some negative effects on cyanobacteria and algae (diatoms) in soil cultures. TDTMA at a concentration 100 mg/L produced some negative effects on all organisms tested in the soil cultures. TDTMA at a concentration 100 mg/L decreased the number of cells per 1 g of soil; the decrease was observed for cyanobacteria, green algae, and diatoms. The experiments revealed the higher sensitivity of the test with the aquatic algal cultures.
