Loamy Sand

Loamy Sand

 

an unconsolidated sandy-clayey sedimentary rock containing 3–10 percent by weight clay particles with diameters less than 0.005 mm. In soil science, loamy sands with clay percentages near the upper limit are called heavy, and those with clay percentages near the lower limit are called light. Loamy coarse sand, loamy fine sand, and loamy very fine sand are distinguished, depending on the grain size of the constituent sand or silt (aleurite). The mineralogical composition of loamy sand varies: all contain considerable quantities of quartz, and the more clayey types contain clay minerals, such as kaolinite and montmorillonite. The term “loamy sand” is usually applied to continental deposits; marine deposits of corresponding composition are classified in a group of sands that have different proportions of clay.

However, given the importance of soil properties on the nature and concentration of soil P pools, it is of interest to assess whether the changes in P pools observed in the loamy sand are generally applicable or whether they are related to soil properties.

Noteworthy points of the article include the following: 1) clay loam soil contained 19 percent more soil organic carbon in 30 cm depth; 2) permanent pasture contained six percent more soil organic carbon pool than forest in clay loam, but 55 percent less in loamy sand; and 3) plowing of pastures drastically decreased the year's soil organic carbon pool in clay loam soil, but increased it in two years for loamy sand soil.
