Background Content

The paper uses the materials of local agroecological monitoring of arable soils of the Belgorod region on the content of manganese, zinc, and cobalt in haplic chernozem of the steppe part of the Belgorod region. The content of manganese, zinc and cobalt in the arable horizon was 1.42, 1.22 and 1.23 times higher than in the parent rock, respectively. A strong correlation was established between the total contents of zinc and cobalt in the soil profile (r=0.77), and the bonds of manganese with zinc and cobalt had the strength of an average value (r=0.59 and r=0.55). The content of mobile forms of the studied trace elements in haplic chernozem is at a low level. The main reason for the shortage of mobile forms of manganese, zinc and cobalt is their low background content in virgin soil.

The Impact

The availability of suitable water is an important factor for increasing the cultivated areas and sustainability in arid (i.e., less than 200 mm precipitation per year) and semiarid regions (i.e., 200–700 mm precipitation per year). Therefore, this study aimed to analyze the impact of treated wastewater (TWW) and groundwater (GW) as well as synthetic fertilizers (50% and 100% of the recommended NPK dose; 150–150–60 kg N–P2O5–K2O ha−1) on the growth, biomass, energy traits, and macro and trace elements of maize (Zea mays L.), sorghum (Sorghum bicolor L.), and pearl millet (Pennisetum glaucum L) grown in old cultivated (first location; L1) and virgin soil (L2 and L3) as potential bioenergy crops. The soil in L1 has been irrigated with treated wastewater for the last 15 years and continued to be irrigated with treated wastewater in this investigation. The virgin soil was divided into two parts: the first part was irrigated with TWW, and the second part was irrigated with GW. The experiments were laid out in a split-plot with a randomized complete block design with water treatments (TWW in old and virgin soil, and GW in virgin soil) in main plots, and the two treatments of fertilization (50% and 100% of the recommended NPK dose) were distributed randomly in subplots. Compared with the crops irrigated with GW, the crops irrigated with TWW, whether grown on old or virgin soil, showed higher plant height, total chlorophyll content, leaf area per plant, total biomass, energy content, and gross energy with low ash. They also contained higher (but lower than permissible limits) concentrations of macro-elements (NPK) and trace elements (Fe, Mn, Cu, Zn, Cd, Pb, Ni, and Co). In addition, the application of a 50% recommended dose of NPK with TWW showed equivalent results to a 100% recommended dose of NPK on all measured parameters with few exceptions. In conclusion, the TWW can be used to irrigate field crops allocated for bioenergy production in arid regions because it does not harm the plants and environment. In addition, the 50% recommended dose of NPK fertilizer exerted no negative effects on the growth and energy production of field crops, thereby protecting the environment and reducing the leaching of excessive fertilizers into GW.

The article highlights the results of the research content of mobile forms of certain trace elements in the water for watering sheep, pasture soils and feed of «Radvan Nowa» farm, Beregy village, Pustomyty district, Lviv region. The aim of research was to examine the actual content of certain trace elements (Cu, Fe, Mn, Zn, Co, Pb, Ni, Cd), determine the deviation of studied mobile forms of trace elements from the maximum permissible concentration (MPC) and to establish the suitability of soil and water in the area for livestock. Also determine the trace elements availability of feed on the farm. Reseived results indicate that the water in this sector meets sanitary standards for the content of trace elements studied and can be used for watering sheep without any reservations and ground land suitable for future use and livestock. The content of trace elements in the soil – water – feed on the «Radvan Nowa» farm, Pustomyty district, Lviv region is the insufficient level that makes it impossible to use the available forage in feeding sheep without further introduction of corrective diet supplements and premixes. The lowest content in the feed was Copper, discovered that in the rough and succulent feed was at an availability of 21.1% from the norm, and in grain feed grain – 6.5% of normal. The highest level of availability of feed was Zinc, observed that in the rough and succulent feed average content 61.8% of normal and the grain was at 76.4%. Further findings will be used to correct diets and explore new trace element supplements for lambs for fattening in the summer.

The data on the content and reserves of trace elements (Mn, Cu, Zn, Co, Mo, B) in soils, reveals patterns of their distribution and quantitative characteristics of relationships in the “soil-plants” system in agrocenoses of the Omsk Irtysh Land have been systematized in the article. The assessment of trace elements in soils and plants has been carried out from the ecological and agrochemical positions. The peculiarities of the intake and accumulation of trace elements in plants depending on zonal soil and climatic conditions have been revealed. Indicators for evaluating the potential of trace elements entering plants have been proposed, and its comparison for diff erent trace elements in the “soil-microfertilizerplant” system has been given. The use of this indicator in calculating and normalizing fertilizer doses and predicting the accumulation of trace elements in plants has been justified. The regularities of the distribution and shape of boron in diff erent types of soils of saline complexes have been studied. For the fi rst time a comprehensive assessment of the effect of high boron concentrations on crop productivity was carried out. A system of indicators for diagnosing the toxic eff ect of the element on plants and a scale of their borostability has been developed. The factors affecting the intake of boron in plants and their resistance to excess of the element have been revealed. Quantitative parameters of the eff ect of chemical reclamation on the boron content in the “soil-meliorant-plants” system have been obtained. The scheme of soil-geochemical zoning of the territory of the Omsk region reflecting the availability of trace elements in the soil has been developed. New data on the availability of trace elements in the main arable soils of the surveyed territory have been presented. The values of optimal levels of trace elements for agricultural crops were corrected. The economic and bioenergetic effi ciency of methods for optimizing plant nutrition with trace elements under the environments of agrocenoses of the Omsk Irtysh Land have been revealed.

Trace elements with a low mobility and with a low transfer are Cu, As, Be, V, Cr, Hg. Copper has at low mobility an increased transfer quotient (content plant/soil). The lowest mobility and transfer show Cr and Hg. Only at the very high contents or increased mobilities of trace elements, which accompany the anthropogenic contamination, soil critical loading for crops can be attained. Because of the amount of the examined extremes, it was not possible to derive the proper critical values. Therefore we were able to assess only critical protective values. They represent minimum total contents of trace elements or their mobile forms, which eliminate risks.

Inner Ear Development

Manganese, zinc and copper are essential for normal prenatal and neonatal development. Manganese deficiency causes skeletal abnormalities, congenital ataxia due to abnormal inner ear development, and abnormal brain function. Depression of mucopolysaccharide synthesis and manganese superoxide dismutase activity may be fundamental to ultrastructural and other defects. In copper deficiency, neurological and skeletal abnormalities are due to impairment of phospholipid synthesis and collagen crosslinking, and possibly to low activity of copper metalloenzymes. The fundamental defect leading to the extremely teratogenic effects of zinc deficiency is related to depressed synthesis of DNA. In the neonatal period, poor survival and growth and depressed function of the immune system are salient features. Developmental patterns of trace element concentrations in various tissues suggest that important changes in metabolic regulation of trace elements may occur during the neonatal period. This hypothesis is being investigated by studies of molecular localization of trace elements in certain neonatal tissues, in conjunction with similar observations in milk.

The study of five soil profiles developed on carbonatic sediments of Tertiary Miocene origin has been carried out. The topography of the area was basically flat and the traditional uses of the soils are the cultivation of dry cereals and grapevine. The geochemical characterization of the aforementioned profiles involves a study of the contents of major and trace elements among other pedologic aspects (texture, pH, organic matter, etc.). The results of this study also indicate a superficial enrichment of trace elements due to the leaching of Ca and moderate biological and anthropic activity. We can consider strontium, Sr, as the trace element that characterizes these limy soils (435 mg/kg average content in total soil and 708 mg/kg in the original rock). These contents are similar to the average value in Castilla-La Mancha of 380 mg/kg and are higher than the average in world soils of about 200 mg/kg. High levels of dangerous or pollutant elements (Cd, Hg, Pb, Cu, Zn, or Ni) were not detected. The majority of trace element anomalies are related to calcareous material and the leaching of calcium carbonate (Ca), while the influence of the anthropogenic factor is secondary. Soil quality does not indicate toxicity although surficial enrichment suggests a weak threat from consuming crops.

A portable raised soil bed integrated with a self-regulated irrigation system was designed, developed and evaluated. The system is most suited to urban settings where arable soils are scarce to locate and most times too expensive to purchase. The system was evaluated with Palm fruit fibre. Palm fruit fibre filled to thickness of 0.15m when saturated was observed to release moisture throughout the entire 0.20cm thickness of the overlaying soil at an application efficiency of 65%, fibre efficiency of 18% and overall efficiency of 12%. It was established from the soil moisture data recorded at different depths in the soil profile that the system provided subsurface irrigation sufficient for vegetable growth and is also efficiently self-regulated as no case of moisture overflow or flooding at the surface of the soil profile was recorded.
