Nickel is a kind of rare metal which is widely distributed in the earth's crust, and is mainly used in manufacturing alloy. Nickel is a trace element essential to animals and plants growth and development, but high concentration of nickel will hamper the growth of plants and animals, and even produce toxic effects. This paper summarizes the physical and chemical properties of nickel, the sources of organisms exposed to nickel and the influence of different concentrations of nickel on animal and plant, and summarizes the relevant research progress.

Energized water production: Underground water, which was not con-taminated with heavy metal ions, chemicals, and much nitrate, etc. => 1) filtering through reversed osmosis pressure filter, 2) nano-sized mineral system with specific stone powder, 3) far red light expositing system, 4) magnetic field treatment, 5) oxygen supply system => energized water (EW). Physical and chemical properties: EW showed higher pH level, electrical conductivity (EC), energy levels by Killian camera and oxygen concentration; however, lower ORP, cluster size as much as 79 Hz by NMR in comparison to underground water, as control. Bioassay of sprouting vegetable plants: In barley germination test, EW showed higher germination rate, strong top/root growth, especially outstanding differentiation of roots in comparison to control. After 2 weeks, the control barley seedlings showed significant symptoms of senescence in root tissue. Also, bean sprouts greatly increased growth in epicotyls and hypocotyls, and development under EW conditions. The roots of control plants showed discolored and mal flavors and gradually decayed in room temperature. With EW supply, vegetable seeds and sprouting plants showed better growth and development of top and root parts. In conclusion, EW influenced the plants to have higher biodynamic potentials for seed germination and growth and development of new plant tissues.

Environmental Context.Agrochemicals have contributed greatly to modern agriculture, allowing better yields and lower costs. However, their extensive use has led to frequent contamination of underground and surface water. A better knowledge of the fate of pesticides from the sprayer to the water that would take into account the diversity of the physical and chemical properties of the various molecules and environmental conditions should help in the challenge of protecting and restoring natural water quality. Abstract.The intensive use of terbumeton (N-(1,1-dimethyl)-N′-ethyl-6-methoxy-1,3,5-triazine-2,4-diamine) has resulted in its widespread presence, together with its main metabolites, in surface- and groundwater. To estimate the fate of these compounds, their adsorption and desorption properties were studied in vineyard soils. The values of the organic carbon normalized adsorption coefficient (KOC) for terbumeton (34.6 and 39.2 L g−1) were significantly higher than those of its metabolites (between 6.8 and 21.1 L g−1). Terbumeton exhibited a higher adsorption capacity and a lower desorption potential as compared with the metabolites. An important hysteresis was observed in all cases. The Freundlich isotherms exhibited a linear shape, which was interpreted as non-specific interaction. The influence of copper(II), a ubiquitous metal cation in vineyard soils, on pesticide sorption was also studied. Copper significantly decreased the amount of adsorbed terbumeton when present in a high concentration (2 ×10−4 M).

Continuous cropping obstacle is a big problem of Strawberry planting. Continuous cropping obstacle leads to the accumulation of phenolic acids, imbalance of soil microorganism, deterioration of physical and chemical properties, resulting in sharp decline in Strawberry yield and quality. At present, the prevention and cure of continuous cropping obstacle of Strawberry is an urgent problem to be solved. The pathogen does not produce drug resistance, is safe to fresh fruit and does not pollute the environment.

Soil plays an important role for sustainable agricultural development which is a widely accepted fact. The composition of soil makes perfect recipe for proper growth and development of growing plants. Mainly the texture and contains of the soil give an idea about overall productivity of any type of soil. The present case study was conducted on the physical and chemical properties of soil at Rajgurunagar (Khed) Tehsil, Pune District (Maharashtra) state of India. The study has been conducted in 5 different localities of different directions for better understanding of nature and composition of soil. Rajgurunagar(Khed) is well known for upcoming developing region due to accumulation of various industrial companies such as SEZ, MIDC and many more. The effect of industrialisation on hydrosphere, atmosphere and lithosphere is noticeable in this Tehsil as an effect is seen on plant growth and development and is affecting on abundance, density of many plant as well as animal species. The total land area is unmanageable for agricultural development purpose. The impact of environmental factors on the soil attributes such as soil particle size which are the product of high degree of soil pollutants, organic matter content which show variability at different localities and other chemical constituents which indicate high degree of salt presence. The control measures are also indicated in a given study to overcome challenging and problem associated conditions.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.
