Jan 24, 2023 · Soil texture is an important soil characteristic that influences many aspects of soil quality. The textural class of a soil is determined by the percentage of sand, silt, and clay. Soils are usually made up of a mix of the three particle sizes.
Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...
Soil is the outer loose layer that covers the surface of Earth. Soil quality is a major determinant, along with climate, of plant distribution and growth. Soil quality depends not only on the chemical composition of the soil, but also the topography (regional surface features) and the presence of living organisms.
The texture of the soil determines its porosity and permeability. Soil porosity is a measure of the volume of pore spaces between soil grains per volume of soil and determines the water and air (oxygen) holding capacity of the soil. Coarse grains with large pores provide better aeration and fine grains with small pores provide good water retention.

Sep 19, 2011 · Published Soil Quality Definitions. There have been many definitions of soil quality since the introduction of the term by Warkentin and Fletcher (1977). Two of the most concise definitions of soil quality are: "Fitness for use" (Larson and Pierce, 1991) and "the capacity of a soil to function” (Karlen et al., 1997).

A typical loam soil is made up of about a 20:40:40 mixture of clay, silt and sand. If the percentage of sand is a little higher, the soil is called a sandy loam, and if the percentage of silt is a little higher the soil is a silty loam. The texture of the soil determines its porosity and permeability.
