Grassland
Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs.

Porosity
Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%.

Sesquioxide
A sesquioxide is an oxide containing three atoms of oxygen with two atoms (or radicals) of another element.

Soil horizon
A soil horizon is a layer parallel to the soil surface, whose physical characteristics differ from the layers above and beneath.

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

Soil type
In terms of soil texture, soil type usually refers to the different sizes of mineral particles in a particular sample.
