Soil Preface Flashcards
A chemical term referring to basic reaction where the pH reading is above 7.0, distinguished from acidic reaction where the pH reading below 7.0
Alkaline
A substance containing hydrogen that dissociates to form hydrogen ions when dissolved in water term applied to any substance with a pH less than 7.0
Acid
A substance which gives off hydroxyl ions when dissolved in water, as contrasted with an acid, which gives off hydrogen ions
Base
The property or power of conducting heat, electricity, or sound
Conductivity
To supply the necessary mineral and organic nutrients to soil or water to aid the growth and development of plants
Fertilize
A mineral calcium sulfate, combined with water of hydration. In arid regions, large tonnages are used to treat sonic soils
Gypsum
A colorless, odorless, flammable gas, The lightest of The elements, that combines chemically with oxygen to form water
Hydrogen
The ion OH-
Hydroxyl
An atom or a group of atoms carrying an electrical charge, which may be positive or negative
Ion
The artificial application of water to soil for the purpose of increasing plant production
Irrigation
The removal of soluble constituents from soils or other materials by percolating water
Leaching
Strictly, calcium oxide, CaO, but as commonly used in agricultural terminology, calcium carbonate, and calcium hydroxide, are included. Agricultural lime refers to any of these compounds , with or with magnesium carbonate, which are used as amendments chiefly for acid soils
Lime
An element or compound in a soil that is essential for the growth of a plant.
Nutrient
Produced by plants and animals; of plant or animal orgin
Organic
A numerical measure of acidity or hydrogen ion, acidity of a substance such as food or soil. the neutral point is pH 7. All pH below 7 are acid and all above 7 are alkaline
