The physical and chemical properties of biochar that has been aged in soil or compost, or passed through the gut of animals, are different from fresh biochar. The properties of aged biochars depend also on the type and properties of soil, microbial dynamics, tillage methods, type of plantsgrown, type of fertiliser added and other environmental factors (e.g. rainfall, temperature).
Alkaline earth metal — Wikipedia Republished // WIKI 2
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.

In conclusion, dialysis vintage >6 years, calcium phosphate products >55 (mg/dL)(2), and cinacalcet use before kidney transplantation are strong predictors of persistent hyperparathyroidism. High-risk patients should be evaluated for parathyroid enlargement, and parathyroidectomy must be considered before kidney transplantation.
Properties of Brass Metal | Our Pastimes
The properties of brass vary according to the ratio of copper (55 to 90 percent) to zinc (10 to 45 percent) and the addition of small amounts of other metals such as tin, aluminum, lead and nickel. A good conductor of heat and electricity, brass is valued for its strength and malleability, which means it is both durable and easy to shape and stamp when making hardware and decorative objects.
Chapter 1 - The Alkaline Earths as Metals - Elsevier
Calcium is found in “Chalk”, “Limestone”, “Gypsum” and “Anhy-drite”. Magnesium is the eighth most abundant element in the Earth’s crust, and calcium is the ﬁfth. Some of the physical properties of the alkaline earth metals are shown in Table 1.3. The metals of
Calcium | Ca (Element) - PubChem
The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.
