Technological components of cultivation systems of the soil, especially tillage and all interventions from surface caused by harvesting, harvest transport, maintenance cultivation, have a great impact on soil condition in general, but especially on the physical state of soil, and also have a great impact regarding aeration conditions from the surface and from soil profile. Intensity effects on soil depend on the one hand of the natural conditions in which the soil formed and weather conditions from crop growing season and on the other hand depend on anthropogenic factor generated by the technological system. Because changes in soil aeration are extremely dynamic, determinations regarding characterization of air movement and air content should be made in dynamic during the entire period of air stress. The data obtained are useful in establishing optimal conditions for application tillage systems. Also, knowing aeration conditions specific for different cultivation allows to set necessary need for drainage and to use appropriate agricultural works. Therefore, especially in irrigated areas were more strongly manifested physical processes of soil degradation at surface. Experiments were performed in the south areas from Romania on preluvosoil from Tancabesti/Periş using an apparatus for determining permeability named Eijkelkamp model.

The paper presents the process of developing long-term action bioenhancers from protein waste originating from tanneries and their application in agriculture for plant growth and remediation of degraded soils. Conditioning the soil consists in improving the physical characteristics through the use of substances of various origins, known in the literature as soil conditioners – soil conditioning agents. The main objective of the paper is to improve soil structure on the surface of the germinative bed using multi-compound systems of biopolymers and thus providing better conditions for plant spring, growth and development, especially in species in which seed is inserted into the soil at shallow depth (up to 4 cm) and using structurally stabilized soil. The aim was to obtain state-of-the-art bioenhancers, with the mission of potentiating the transfer of nutrients obtained by means of the protein fertilizer to the plant and fruit, resulting in metabolism stimulation, speeding the productive phase, stimulation of the plant's self-defense system and optimization of mechanisms responsible for the health of fruits. The most remarkable advantage of using protein bioenhancers, obtained from protein waste is the positive impact on the development and health of the plant, as well as on its resistance to stress factors (drought, salts and pesticides). After the experiments, it can be concluded that protean bioenhancers samples gave good results both in terms of improving soil quality, and plant growth in high culture. © SGEM2015.

Following the accident at the nuclear power plant in Chernobyl a number of different remedial actions were developed and implemented in Belarus, Russia, and Ukraine. Recommendations on the application of countermeasures and remedial actions were published by the IAEA as "Guidelines for agricultural countermeasures following an accidental release of radionuclides" in 1994. Since then, new information on the behaviour of radionuclides in the environment and effectiveness of countermeasures in the long term has been obtained and reviewed by many projects, including the Chernobyl Forum. Additionally, new approaches to derive remediation strategies were developed and successfully implemented in the most affected countries. This paper describes a justification of the remediation strategies suggested for rehabilitation of the areas most affected by the Chernobyl accident based on this experience. © 2010 Elsevier Ltd.

Radioactive contamination of the environment following the Chernobyl accident still provide a substantial impact on the population of affected territories in Belarus, Russia, and Ukraine. Reduction of population exposure can be achieved by performing remediation activities in these areas. Resulting from the IAEA Technical Co-operation Projects with these countries, the program ReSCA (Remediation Strategies after the Chernobyl Accident) has been developed to provide assistance to decision makers and to facilitate a selection of an optimized remediation strategy in rural settlements. The paper provides in-depth description of the program, its algorithm, and structure. © 2010 Springer-Verlag.

Most tanneries and leather goods manufacturers are facing serious problems regarding waste disposal, the more so as their storage in landfills leads to negative effects on the ecosystem. Using untanned wastes is of particular interest because it offers the opportunity to eliminate nearly all wastes from fleshing, while obtaining qualitatively and economically valuable products. Organic biopolymers are a source of raw material for agriculture, whereas the composition of protean wastes provides sufficient elements to improve the composition and remediation of degraded soils and plants can exploit some elements, such as nitrogen, calcium, magnesium, sodium, potassium etc. As a result of the existing large quantities of organic waste, it is known from technological practice that from processing one tonne of raw hide, 75% is discarded, of which 50% can be used as organic fertilizer to repair poorly productive or unproductive land areas (sandy, salty, eroded etc.). This scientific paper presents the characterization of protean biopolymers by methods specific for morpho-structural analysis (UV-VIS, IR spectroscopy, thermal analyses, X-ray diffraction, microscopy, etc.). Protean biopolymers were obtained by means of an innovative bioenzymatic procedure of processing protean waste, which in combination with other polymers (polyacrylamide, acrylic, maleic, cellulose, starch, etc.) will be used in agriculture.

This paper is a synthesis of innovative approaches and the results obtained in their research projects in Romania. The results presented refer to the completion of the reference database in the soil physics domain because the air permeability of soils was only partially studied and researched. In addition, this paper further asserted experiments on soil aeration process treated with processed organic compost and the importance of air in the soil. To achieve the objectives of the work case studies were conducted, cases which took into account both air movement in the soil, characterization based on the determination of soil permeability to air, and air content in pilot experimental blocks. The data obtained were used for unifying methodology for the Soil Monitoring System in Romania with a physical assimilation of extreme importance that provides clear indications on irrigation hidromodule and drainage of agricultural land. © SGEM2015.

The paper refers to obtaining protean biopolymers from Ti - tanned leather waste and it also to studying the levigation ability of nutrients for soils treated with titanium-containing biopolymers. Using tanned waste is of particular interest because it offers the opportunity to eliminate all wastes from tanning, while obtaining qualitatively and economically valuable products. Organic biopolymers represent a source of raw material for agriculture, because the composition of protean wastes provides enough elements to improve composition and rehabilitation of degraded soils, and plants can capitalize some elements: nitrogen, calcium, magnesium, sodium, potassium, titanium etc. The wastes used for this innovative procedure for obtaining biopolymers, are obtained from wet white tanned leather through a new technique based on Ti-Al tanning agents. The aim of protein waste hydrolysis is to obtain new products, state-of-the-art protein fertilizers and soil improvers designed to potentiate the transfer of nutrients obtained from the protein soil improver to plant and fruit, with the effect of stimulating the metabolism, speeding up the productive phase, stimulating the defense system of the plant and optimizing mechanisms responsible for the health of the fruit.

The aim of the present study was to describe the biochemical changes induced in regenerants of Fragaria X Ananassa Duch. by the in vitro treatment with fungal elicitors isolated from Trichoderma viride, Penicillium chrysogenum and Botrytis cinerea strains. We combined anatoxinic serum from these three microorganisms to activate different defense signaling pathways in our in vitro system. Strawberry regenerants responded in a complex way to treatments with fungal elicitors with gradual forms of stress, up to foliar necrosis. The enzymes involved in the metabolism of reactive oxygen species (ROS) expressed different activities in the treated variants compared to the control, 24 hrs after the last treatment: superoxid dismutase (SOD) activity increased, while catalase (CAT) and peroxidase (POX) activity decreased, suggesting a significant ROS accumulation, with complex and opposite effects on plant cells, including the activation of hypersensitive cell death. The tested mixture of anatoxinic sera from the three microorganisms acted as a strong external stimulus in our in vitro system. © 2010 University of Bucharest.

Haematuria-inducing areas in the northern and central parts of the Eastern Carpathian Mountains are characterised by the mesozoic-crystalline, neogene eruptive and transcarpathian flysch zones. The rocks have high concentrations of some metals and radioactive elements, some of them bearing polymetallic sulphides. The soils are strongly or moderately acid and oligomesobasic. They have a deficiency of soluble phosphorus and molybdenum, but up to 4.9 times the background content of metallic elements in non-affected zones. The waters have a pH around 7, a low content of salts (0.09-0.62 g L(-1)), but metal levels in excess of 10 times that of the background level. Pasture vegetation has a low nutritional value, and includes up to 12% of poisonous plant species. It is characterised by low total concentrations of P, Mo, N and K, and high total concentrations of metallic trace elements, including high values of Zn and excessive values of Fe, Mn, Pb, Cr, Ni, Cd and Al. Besides clinical symptoms specific to haematuria, sick animals have abnormal blood and urinary compositions and specific morphopathological features. High concentrations of metallic elements were detected in renal calculi. The correlation of the geochemical and biogeochemical features of the haematuria-inducing areas, together with the results of the epizootological, clinical, paraclinical and morphopathological research emphasises that chronic cattle haematuria is a disease with numerous causes, but is primarily a biogeochemical problem in the area studied, making it an ecosystem disease.
