Stable isotope geochemistry is a branch of geology that investigates the age of natural materials, their origin and the processes they have undergone since formation [1]. Stable isotope analysis is also used in biogeochemical studies to monitor element cycling in ecosystems [2] and to identify geographical/regional differences for food provenance and archaeology. Of the elements of interest in ...

BACKGROUND Sale of organic foods is one of the fastest growing market segments within the global food industry. People often buy organic food because they believe organic farms produce more nutritious and better tasting food from healthier soils. Here we tested if there are significant differences in fruit and soil quality from 13 pairs of commercial organic and conventional strawberry agroecos...

All plants must obtain a number of inorganic mineral elements from their environment to ensure successful growth and development of both vegetative and reproductive tissues. These minerals serve numerous functions: as structural components in macromolecules, as cofactors in enzymatic reactions, as osmotic solutes needed tomaintain proper water potential, or as ionized species to provide charge ...

The selective enrichment behavior of a labile substance, such as hydroxides, to the surface of particular mineral particles in river water was clarified by scanning electron microscopy/energy dispersive X-ray microanalysis (SEM-EDX). Individual particles other than diatom collected on a 0.45 microm filter from the Fuji and Sagami rivers, central Japan, were analyzed by SEM-EDX and classified in...

Extraordinary importance of Date-Palm, Phoenix dactylifera especially ‘Piarom’ variety and also undeniable effect of nitrogen and phosphorus on yield and quality of this product, caused this research to be accomplished. The research was performed during two years on 72 (4*3*3*2=72 trees) fruitful, 12 years old trees in Hormozgan province. Treatments were consisted of four levels of nitrogen (0,...

Dietary elements, commonly known as dietary minerals are chemical elements required by living organisms other than the elements present in the common organic molecules. Dietary fibre and minerals are important for healthy functioning of the human body. The mineral nutrition is an important aspect and its pivotal role in human life provides healthy growth. The present study was undertaken to ana...

River-lake systems in Central Europe represent the majority of surface water system forms. In these lakes play an important role river quality. Published reports on quality waters indicate progressive deterioration their quality, resulting mainly from increasing eutrophication. This study analyzed content two biogenic elements—nitrogen and phosphorus—and mineral forms G?uszynka river, represent...

Inorganic elements (metals, non-metals, transition elements, and electrolytes commonly called “minerals” in nutrition science) are critical to all life processes as enzyme cofactors, stabilizers of proteins, structural components of tissues, second messengers, regulators of acid-base balance, participants in redox reactions, and for the maintenance of cellular electrical potential. For this rea...

Effects of bio-nitrogen fertilizer (bio-N), as a partial alternative to mineral-nitrogen fertilizer (mineral-N), on growth, yield and yield quality of broccoli plants were investigated. Bio-N was applied at 1, 2 or 3 doses in combination with 65% of the recommended dose of mineral-N (bio-N1, bio-N2 or bio-N3 + 2⁄3mineral-N). However, 100% of the recommended dose of mineralN was applied as a con...
