meq

A meq is a milliequivalent which is an expression of concentration of substance per liter of solution, calculated by dividing the concentration in milligrams per 100 milliliters by the molecular weight.

Portions of the southern boundary of ecoregion 50 roughly correspond to the southernmost extent of lakes with alkalinity values less than 400 meq/l (Omernik and Griffith 1986).

An analysis of soil nutrients is often expressed in terms of milliequivalents per 100 g of soil (meq/100 g).

Chapter 3 1996

The most productive sites had at least 19-26 cm of well-drained topsoil with at least 3-8% organic matter and an exchangeable potassium of 0.36 meq/100

Chapter 8 1996

C.lloidal organic matter (humus) has C. E.C.of up to 200 meq/100 g.

Chapter 9 1995

However, soils with C. E.C.as low as 4 or 5 meq/100 g can grow irrigated crops provided that sufficient fertilizer is applied and that the interval between irrigations is short.

Chapter 9 1995

The "1: 1" clays such as kaolinite have C. E.C.of 10 to 15 meq/100 g.

Chapter 9 1995

The sum of all the negative charged sites on clay and organic matter in a soil is called the Cation Exchange Capacity (CEC) and is expressed as meq/100 g.

The CEC is expressed in milliequivalents per 100 grams (meq/100g) of soil.
