With such situations, it seems clear that a reduction of food wastage at global, regional, and national scales would have a substantial positive effect on natural and societal resources. Food wastage reduction would not only avoid pressure on scarce natural resources but also decrease the need to raise food production by 60 pe...
This study focused on studies of pesticide residues in organic product. With increasing health and environmental awareness, organic farming has become an integral part of the agricultural policy in many countries. It is the less harmful to human and environment. The target of organic farm is not high quantity of production, but is the high quality. The market value of organic products in Europa...
Previous studies have demonstrated that the toxic effects of 2,4,5trichlorophenol (2,4,5-TCP) are greater in agricultural soils than in forest soils; therefore these effects appear to be influenced by the total C content and soil pH. Agricultural soils (usually low in organic C) contaminated with 2,4,5-TCP may be able to be remediated by the addition of organic waste products. To test this hypo...
© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim 3394 wileyonlinelibrary.com organic synthesis increases the production costs of the compound immensely due to limiting yields of sequential reactions, and thus small improvements in recovery can translate into tremendous economic benefi ts. [ 2 ] Similarly, many renewable energy pathways involve the reduction of stable molecules to form charged ...
Biaryl compounds are versatile building blocks in the synthesis of natural products, pharmaceuticals, agricultural chemicals and π-conjugated organic materials. This review describes a recent progress for the biaryl cross-coupling reaction of heteroaromatic compounds using hypervalent iodine reagent. Our novel biaryl coupling reaction is a unique method for constructing various heteroaromatic b...
The term, biosolids, is generally used to refer to those waste products that have been stabilized by treatment of the sewage sludge for beneficial reuse through appropriate management (Davis, 2002). The agronomic and environmental benefits from the organic material and fertilizing elements contained in the biosolids are essential for maintaining soil fertility. This has been a major reason for ...
The main purpose of this research is review of principles, concepts, problems and solutions of soil ethic. In this research by descriptive method and Delphi technique was used for identifying soil ethical concepts, soil ethical principles, problems and difficulties of soil ethics in Iran and al around the world and suggestions for improvement of soil ethics in Iran. The population of this re...
The definition of soil quality encompasses physical, chemical and biological characteristics, and it is related to fertility and soil health. Many indicators can be used to describe soil quality, but it is important to take into account sensitivity, required time, and related properties, than can be explained. Properties related to organic matter content, such as C/N ratio, organic carbon fract...
Although activated carbon adsorption is an efficient process in water treatment applications, high costs involved in both the production of carbon and the operation of adsorption units have caused to search alternative adsorbents. Agricultural by-products are a group of alternative adsorbent, with only one or several adsorption cycles, which is available locally in a cheap and abundant manner. ...
Secondary phenolic metabolites play an important role in plant defense mechanisms, and increasing evidence indicates that many are important in human health. To date, few studies have investigated the impact of various agricultural practices on levels of secondary plant metabolites. To address this issue, the total phenolic (TP) content of marionberries, strawberries, and corn grown by sustaina...
