Soil acidity affects a plant's ability to absorb nutrients. Alkaline soil has a pH of more than 7.0 -- A soil with a pH between 7.5 and 8.0 is mildly alkaline; 8.0 to 9.0 soils are moderately alkaline; and above that, soil is considered highly alkaline. Plants growing in alkaline (or basic) soil are less able to absorb phosphorus, iron, and manganese. Areas tending to experience drought will often have alkaline soils. In addition to adding organic material, soil can be made less alkaline by adding elemental sulfur.

According to Webster, "1 : a soluble salt obtained from the ashes of plants and consisting largely of potassium or sodium carbonate; broadly : a substance (as a hydroxide or carbonate of an alkali metal) having marked basic properties." Also, having a high carbonate hardness or kH. However, it is sometimes erroneously used to mean water having a pH of above 7.

Having a pH of 7.0 or greater.
Alkaline batteries are an efficient battery type that is both economical and reliable. In alkaline batteries, the hydrous alkaline solution is used as an electrolyte. The most common use of this solution is in a manganese-dioxide primary cell with potassium hydroxide as an electrolyte. During cell discharge, the oxygen-rich manganese dioxide is reduced and the zinc becomes oxidized while ions are being transported through the conductive alkaline electrolyte.
Having a pH greater than 7.0. Liquids are caustic and bitter.

Alkaline substances have a pH over 7.0. They may be added to a material to neutralize acids or as an alkaline reserve or buffer for the purpose of counteracting acids that may form in the future. A buffer may be added during the manufacturing or during the process of deacidification. While a number of chemicals may be used as buffers, the most common are magnesium carbonate and calcium carbonate.

In our context, a substance having a pH above that of neutral water (7.0) when in solution. Signified as pH (potential of Hydrogen), alkaline fluids, such as the blood (pH about 7.4), have the ability to neutralize acids (solutions below pH 7.0). Metabolic wastes are acids, and the alkaline reserve of the blood neutralizes them until they are excreted.

sometimes water or soils contain an amount of alkali (strongly basic) substances sufficient to raise the pH value above 7.0 and be harmful to the growth of crops.
Term that describes a certain pH factor. The pH factor stands for a concentration of hydrogen ions. The more hydrogen ions present, the more acidic the condition. The pH scale reaches from 1 (= very acidic) to 14 (= very alkaline). Pure water has a pH value around 7 and is neutral. Our blood has a pH value of 7.35 (compare also acid-alkaline balance).
Having a relatively low concentration of hydrogen ions, giving water a pH greater than 7.

On the pH scale, a base (opposite of an acid); any substance that combines with hydrogen ions protons); a hydrogen ion acceptor.
A reference to the level of acidity within a chemical environment. When pH greater than 7, the environment is alkaline. When pH less than 7 it is acid.

Term used to describe a material that has a pH of greater than 7.0 in water.
Alkaline metals are from Group 1 (lithium, sodium, potassium, rubidium, cesium, francium) of the Periodic Table. For example, sodium hydroxide (NaOH) is an alkili. They are highly reactive in water. Commonly used interchangeably with base; this is erroneous. All alkalis are bases but not all bases are alkaline! Ammonia is not an alkili, but when dissolved in water it forms one - ammonium hydroxide. Take care to refer to measuring whether something is a base, or to measuring a substance's pH, rather than measuring "alkilinity".
The condition of water or soil which contains a sufficient amount of alkali substances to raise the pH above 7.0.
A highly basic, as opposed to acidic, subtance. For example, hydroxide or carbonate of sodium or potassium.
