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.

Soils with >50% sand were classified as "light" and included sandy loam and loamy sand. There were no consistent differences between soils supporting native vegetation and crested wheatgrass across all site pairs (n = 24) for pH (P = 0.64), electrical conductivity (P = 0.21),% sand (P = 0.78), % silt (P = 0.12), or % clay (P = 0.34).
The three soils used in this study were the Talparo series (clay loam), Piarco series (silt loam) and Arena series (loamy sand).

The survey was conducted from January to December, 2016 by applying line transect technique in eight types of soil (sand, loamy sand, sandy loam, sandy clay loam, loam, clay loam, silt loam, silty clay loam) to determine six soil properties (plant biomass, saturation, electrical conductivity, pH, organic matter, phosphorus and potassium) in Pothwar Plateau (250 km long and 100 km wide).
The major objective of this study was to investigate the wetting pattern of two generally used emitter types (inline and online) on different soils (loamy sand, sandy loam, silt and clay) of Peshawar valley and compare the observed values with model simulation using Drip Irrigation Water Distribution Pattern Calculator (DIPAC) and Drip-Irriwater models.
The soil of the experimental sites was loamy sand and showed limitations regarding pH, P content and thickness (Table 1).
The soil of experimental field was loamy sand in texture, having low in organic carbon (0.41%) and nitrogen (242 kg [ha.sup.-1]) and medium in phosphorus (32 kg [ha.sup.-1]) and potash (263 kg [ha.sup.-1]) with pH 7.5.
Soil at Clayton during 2011 was a combination of a Rains sandy loam (fine-loamy, siliceous, semiactive, thermic Typic Paleaquults), Varina loamy sand (fine, kaolinitic, thermic Plinthic Paleudults), a Wagram loamy sand (loamy, kaolinitic, thermic Arenic Kandiudults), and Norfolk loamy sand (fineloamy, kaolinitic, thermic Typic Kandiudults).
For this reason, in the present study, the comparison between soil hydraulic functions was developed with similar soil textures, taking into account sand, sandy loam, and loamy sand data, as can be seen from Figure 5(a).
A field trial was successively conducted on a loamy sand soil at Ismailia Agricultural Research Station cultivated with wheat (Triticum aestivum L., cv Sakha 69) at winter 2013.
