nowadays, organic fertilizers play an important role in agriculture. they are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. they provide high yield, better quality products and a shorter period of harvesting crops. in this study, the mineral elements: primary macronutrient (n, po3- and k+), secondary macronutrient: (ca2+, mg...

BACKGROUND Although kissra and hulu-mur are well known millet-based foods in Sudan, the effect of fer- mentation and methods of preparation on their chemical compositions has not been thoroughly investigated. The aim of this study was to investigate the method of preparation and the composition of kisra, and hulu-mur. METHODS The effect of fermentation and method of preparation on the composi...

The aim of this review is to examine the hypothesis that organic matter decreases the adsorption of radiocaesium on clay minerals. The factors that determine radiocaesium mobility and bioavailability in soil are briefly outlined to show why a relationship between soil organic matter content and enhanced Cs bioavailability is paradoxical. In all the investigations reviewed the ionic compositions...

In the southeast of bam, there is a collection of volcanic rocks with andesite, basalt and trachy andesite composition. The texture of these rocks are often porphyritic with microlithic, porphyric cavity, and sometimes glomerulophorphuri, sore throat trachytic. Main minerals include Olivine, Clinopyroxene, Plagioclase and secondary minerals including opaque minerals, Iodenzyte, secondary Biotit...

Minerals are defined as naturally occurring, inorganic, solids with a definite chemical composition and a regular, internal crystalline structure. The keys to this definition are the chemical composition and the crystalline structure. Different chemical compositions result in different minerals. A good example is the mineral plagioclase. Plagioclase is a member of the feldspar group, but there ...

BACKGROUND Multivitamin/multimineral (MVM) supplements are commonly consumed by the general population, but little is known regarding their composition and compliance with local regulations. We assessed the composition and compliance with regulations [no indication in the label of vitamin/minerals amounting <15% of the acceptable daily intake (ADI)] of MVM available in Switzerland. METHODS Th...

Crops diversity and maintaining and enhancing the fertility of agricultural lands are basic principles of organic farming. With a wider range of crops in agroecosystem can improve the ability to control weeds, pests and diseases, and the performance of crops rotation and food safety. In this sense, the main objective of the research was to study the productivity and chemical composition of some...
