Plant Nutrient | Essential Elements

Magnesium is also an essential nutrient for animals. If forage crops, commonly grasses, are low in magnesium, grazing animals may develop hypomagnesia, sometimes called grass tetany. For this reason, many studies have been conducted on magnesium

Types of Glass

In the 19th century German Scientist Otto Schott (1851-1935) used scientific methods to understand the effect of different chemicals that can be used to make the different types of glass. Otto Schott teamed up with his German colleague Ernst Abbe (1840-1905) one of the owners of Carl Zeiss to make further technological advances in the understanding of glass.

The history of aluminium industry

The USSR stepped up the tempo of their aluminium production through the use of hydroelectric plants in Siberia and in doing so, became the world''s aluminium market leader. In the mid-1960s two giants of the aluminium industry, the Bratsk and Krasnoyarsk aluminium smelters, which each had the capacity of 1 million tonnes of metal per year, were commissioned in Siberia.

Handbook of Plant Nutrition

 · Since organs of plants vary in composition and since the proportions of organs vary with the nitrogen status of plants, a particular organ of a plant is usually chosen for analysis. Conducting tissue, such as that of stems or petioles, may provide the best index of the response of plants to nutrient applications or the best index of the nutrient status at a given time in growth.

Catalase function in plants: a focus on Arabidopsis …

Although some bacterial catalases use manganese as the redox-active co-factor, all known eukaryotic forms are haem-based (Zamocky et al., 2008). The best-characterized type of haem-dependent catalase is found in diverse organisms, including prokaryotes, fungi, animals, and plants, and is composed of ''typical'' or ''monofunctional'' catalases ( Chelikani et al., 2004 ).

Top five mining companies across Australia profiled

 · The discovery of copper soon took over as the nation''s top export, but it was the discovery of gold in 1851, near Ophir in New South Wales, that triggered the real mining frenzy. With about 350 operational mines, Australia produces 19 minerals including iron ore, bauxite (aluminium ore), lithium, lead, gold, diamond, zinc and uranium.

Essential micro-(trace) elements | SpringerLink

Abstract. For nearly half a century following the classical researches with water cultures of Sachs and Knop in 1860 it was generally accepted that for the vast majority of plant species, if not all, ten elements, and ten elements only, were essential for healthy growth. The ten elements were carbon, hydrogen, oxygen, nitrogen, phosphorus ...

Plants need to endure different abiotic stresses and polyphenols accumulate in response to these stresses helping plants to acclimatize to unfavorable environments [25,26]. Hence, the concentration of phenols in plant tissue is a good indicator to predict the extent of abiotic stress tolerance in plants which varies greatly in different plant species under an array of external factors.

Herbal medicine

Plants have chemical defense mechanisms against predators that can have adverse or lethal effects on humans. Examples of highly toxic herbs include poison hemlock and nightshade. [45] They are not marketed to the public as herbs, because the risks are well known, partly due to a long and colorful history in Europe, associated with "sorcery", "magic" and intrigue. [46]
