Equivalent (chemistry)

An equivalent (symbol: equiv) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount of another substance in a given chemical reaction.

Flocculation

Flocculation, in the field of chemistry, is a process wherein colloids come out of suspension in the form of floc or flake, either spontaneously or due to the addition of a clarifying agent.

Hydraulic conductivity

Hydraulic conductivity, symbolically represented as K, is a property of vascular plants, soils and rocks, that describes the ease with which a fluid (usually water) can move through pore spaces or fractures.

Infiltration (hydrology)

Infiltration is the process by which water on the ground surface enters the soil.

Magnesium

Magnesium is a chemical element with symbol Mg and atomic number 12.

Residual sodium carbonate index

The residual sodium carbonate (RSC) index of irrigation water or soil water is used to indicate the alkalinity hazard for soil.

Soil conditioner

A soil conditioner is a product which is added to soil to improve the soil’s physical qualities, usually its fertility (ability to provide nutrition for plants) and sometimes its mechanics.

Soil structure

Soil structure describes the arrangement of the solid parts of the soil and of the pore space located between them.
