| - | **AGLIME- **Also know as "agstone". Calcitic or dolomitic limestone that is crushed and ground to a graduation of fineness that will allow it to neutralize soil acidity. Usually material is ground to pass sieves from 8- to 100- mesh range or finer. | + | **AGLIME- **Also know as "agstone".

| - | **DOLOMITE- **Limestone that contains magnesium carbonate (MgCO<sub>3</sub>) in an amount //approximately equivalent// to the calcium carbonate content in the stone. Limestone containing magnesium carbonate in lesser proportions is referred to as magnesian limestone or dolomitic limestone. Pure dolomite is 54.3% CaCO<sub>3</sub> and 45.7& MgCO<sub>3</sub> or expressed another way, is composed of 30.4% CaO, 21.8% magnesia (MgO), and 47.3% CO<sub>3</sub>. | + | **DOLOMITE- **Limestone that contains magnesium carbonate (MgCO<sub>3</sub>) in an amount //approximately equivalent// to the calcium carbonate content in the stone.

| - | **EFFECTIVE CALCIUM CARBONATE EQUIVALENT- **An expression of aglime effectiveness based on the **combined** effect of **chemical purity (CCE**) and **fineness**. It is required for labeling purposes in some states. Determined by multiplying CCE by a set of factors based on the fineness of grind of the limestone. Also referred to as effective neutralizing value (ENV), total neutralizing power (TNP), effective neutralizing material (ENM) and, in one state, as the &quot;lime score&quot;. | + | **EFFECTIVE CALCIUM CARBONATE EQUIVALENT- **An expression of aglime effectiveness based on the **combined** effect of **chemical purity (CCE**) and **fineness**.

| - | **FLUID LIME- **Also known as &quot;liquid lime&quot;. This product is made by mixing very finely ground limestone (100% passing a 100 mesh sieve and 89-90% passing a 200 mesh sieve) with either water or liquid nitrogen fertilizer along with a suspending agent (attapulgite clay) and applying with a liquid fertilizer applicator. | + | **FLUID LIME- **Also known as "liquid lime".

| **GYPSUM- **A hydrated form of calcium sulfate (CaSO<sub>4</sub>). It supplies calcium to the soil, but it is a neutral substance and does not correct soil acidity; therefore it is not a liming material. | **GYPSUM- **A hydrated form of calcium sulfate (CaSO<sub>4</sub>).

| **HYDRATED LIME- **Produced by adding water to burned lime or by absorption of moisture from the air. It has the same characteristics and limitations as burned lime. | **HYDRATED LIME- **Produced by adding water to burned lime or by absorption of moisture from the air.

| - | **MAGNESIUM OXIDE (MgO) - **The chemical compound composed of magnesium and oxygen. It is formed from MgCO3 by heating to drive off the carbon dioxide, or in mixture with CaO by heating magnesian limestone or dolomite. Also known as magnesia, it occurs in nature as periclase. | + | **MAGNESIUM OXIDE (MgO) - **The chemical compound composed of magnesium and oxygen.

| - | **SOIL pH- **An expression of the degree of acidity or alkalinity of a soil, measured on scale of 1 to 14. Readings from 1.0 to 6.9 indicate that a soil is acid (sour); from 7.1 to 14.0 that it is alkaline (sweet). A reading of 7.0 is neutral. The term &quot;pH&quot; refers to negative logarithm (p) of the hydrogen ion (H) concentration in soil solution. | + | **SOIL pH- **An expression of the degree of acidity or alkalinity of a soil, measured on scale of 1 to 14.
