Leachate Water

This study aimed at assessing the effect of how submontane soils are managed on the quantity and quality of leachate water, as well as on the load of nutrients leached with it. The quality of leachate water moving through the soil profile at the depth of 0–30 cm was investigated. The quality of leachate water from six research variants was analyzed in three periods: intensive growing, inhibited growing, and the non-growing season. It was established that the type of flora had a significant effect on the amount and chemical composition of water flowing through the soil profile. The highest loads of minerals were leached with leachate waters from arable land. Contrary to the common opinion, unused meadow had the best quality of leachate waters. On account of the quality of leachate waters in submontane and montane areas, it is recommended to reduce plow tillage in these areas. It is also recommended to use these areas as meadows and pastures, with moderate fertilization and rational use, i.e., two mowings or three grazings during the growing season. The study emphasizes how important the management of the use of submontane and montane areas is for the quality and quantity of leachate waters.

This article presents the study results of the change dynamics in the chemical composition of water in Lake Iskanderkul and the rivers flowing into it, as well as the comparison of water quality in the water bodies of the Iskanderkul Basin and several mid-stream tributaries of the Zarafshan River. It was established that the chemical composition of water in Lake Iskanderkul and its tributaries meets the requirements of the corresponding state standard (GOST 2874-82 “Drinking Water”). However, in terms of dissolved oxygen, copper, zinc, lead and iron the water in Lake Iskanderkul does not satisfy fish farming requirements. The main water pollution sources in the area include such natural phenomena as floods, avalanches, mudslides, and rock dissolution.

In recent years, it has been shown that biostimulants can efficiently enhance plant metabolic processes, leading to an increased production of essential oil (EO) in aromatic plants. The present study aimed to evaluate the effects of two different commercial biostimulants composed of amino acids and seaweed extract, normally used for food organic crops, on the production and composition of EO and hydrosol of Lavandula x intermedia, cultivar “Grosso”. The products were applied during 2020 growing season on lavender crops in three different locations of the Northern Italian (Emilia-Romagna Region) Apennines. Plants were harvested and EOs extracted by steam distillation and analyzed by gas chromatography. Both biostimulants affected the yield of EO per plant (+11% to +49% depending on the treatment/farm combination) without significantly changing the chemical composition of EOs and hydrosols. Conversely, the composition of EOs and hydrosols are related to the location, and the main compounds of “Grosso” cultivar, limonene, 1,8-cineole, cis-ocimene, linalool, camphor, borneol, terpinen-4-ol, and linalyl acetate, show different ratios at the experimental test sites. The differences might be due to the sunlight exposure and various maintenance of the crops over the years. In conclusion, these results suggest that the employment of biostimulants on lavandin crops do not endanger the quality of the EO while increasing biomass production and promoting the sustainability of the crop.

In the present study, the chemical composition of water extracts of Chinese and Vietnamese cassia (Cinnamomum cassia) were compared using multivariate analysis of LC-MS data. By principal component analysis of the LC-MS data, 6 compounds, cinnzeylanine (1), cinnzeylanol (2), anhydrocinnzeylanol (3), cinncasinol A (4), epicatechin (5) and procyanidin B2 (6), were identified as the marker compounds to characterize Chinese and Vietnamese cassia. It was clarified that Chinese cassia contains relatively larger amounts of epicatechin and procyanidin B2. On the other hand, Vietnamese cassia is characterized by a relatively larger amount of diterpenes. As catechin derivatives and diterpenes have different types of activity, it is important to choose the cassia that best suits the product for which it is to be used, whether in food or in herbal medicine.

Final Effect

The common reed (CR) is one of the plants which grows in some area of Iran and other world countries especially in coastal wetlands. Feed resource restriction is the most problem in animal production in some area and native plants have a key role. Ensiling may improve the quality of crop or decrease by high fermentation. These effects depend on stage of growth, chemical composition, dry matter and nutrients of plant, and final effect is not as same as for all crops. For understanding the effect of ensiling on quality of each plant must be investigate. For this reasons goals of this experiment was investigation on various methods of utilization of CR for finishing male calves and comparison with alfalfa.

The analysis of the use of the land fund of the Krasnodar Territory and the analysis of the rational use of land resources were conducted, using the following coefficients: coefficient of arable land, coefficient of plowing of the territory, and territory development coefficient. The paper discusses the techniques and methods of statistical analysis of the distribution of the land fund by categories of land in the Krasnodar Territory for 2005-2019. Since the area of land by categories changes in dynamics, the indicators of the growth rate, increase, and average values of the series were used. This gives an understanding of how intensively the land areas of the Krasnodar Territory change. The analysis of the use of the land fund of the Krasnodar Territory is necessary in order to determine the possibilities for a more rational and effective use of it, as well as to preserve and improve the quality of the land. Therefore, it is relevant.

A fastening of sleeper is an important part to bind rail, sleeper and foundation under the track, which requires enough strength, elasticity et al.. This article focuses on the common occurrence of fracture on a casting fastening baffle by metallographic analysis of the materials of different part in the casting, and reaches the conclusion that the unevenly distribution of chemical composition is due to the different cooling rate of different wall thickness. The low carbon content in thin wall and the lack of pearlite with high strength in matrix structure aggravates the danger of the emergence of cracks. Then a solution is put forward, which is to improve the structure of the casting and reasonably arrange the inner runner when casting.
