The Serengeti volcanic grasslands are an edaphic plant community that grows on soils derived from volcanic ash. The eruption of the now-extinct Kerimasi volcano 150,000 years ago deposited huge amounts of fine whitish-grey ash. More recent eruptions of the Ol Doinyo Lengai volcano deepened the ash deposits.
Ash is the solid remnants of fires. [1] Specifically, ash refers to all non- aqueous , non- gaseous residues that remain after something burns . In analytical chemistry , to analyse the mineral and metal content of chemical samples , ash is the non- gaseous , non- liquid residue after complete combustion.
Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant. It is largely composed of calcium compounds, along with other non-combustible trace elements present in the wood, and has been used for many purposes throughout history.
Eucalyptus regnans or mountain ash of Australia also shows a unique evolution with fire, quickly replacing damaged buds or stems in the case of danger [citation needed]. They also carry their seeds in capsules which can be deposited at any time of the year [citation needed]. During a wildfire, the capsules drop nearly all of their seeds and the ...
Fraxinus angustifolia subsp. angustifolia has become a weed in many parts of Australia, where it is known as Desert Ash. It has been widely planted as a street and park tree, and has spread to native bushland and grasslands, as well as stream banks and drainage lines, out-competing native plants for moisture, light and nutrients.

Mountain ash does not like heat and humidity; it grows well only in cooler climates from Zones 2 to 6. Although its native range extends to the Carolinas and Georgia, it only grows there at high ...
A crucible and tongs, on a green mat. The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains. The residues after a sample is completely burnt - in contrast to the ash remaining after incomplete combustion - typically consist of oxides of the inorganic elements present in the original sample.
Lime can improve crop yield and the root system of plants and grass where soils are acidic. It does this by making the soil more basic, allowing the plants to absorb more nutrients. Lime is not a fertilizer but can be used in combination with fertilizers. [3] [4] Soils become acidic in several ways.
