Discovering the Properties of Soils

Discover the nature of the soil "The soil creates a foothold, it is the source of water and nutrients, biological and chemical substances act on the roots.The nature of the soil is related to the functional relationship with the plant species There is a relationship only "(Stone 7). The soil scientist must reexamine the hypothesis to explain the scientific method, the process of hypothesis, the verification of hypothesis by experiment, guidance of conclusion, and change of soil properties. Soil scientists also use this method to describe the soil of the natural environment.

Various laboratory tests can be carried out on the soil in order to measure various soil properties. Some soil properties are inherent in the composition of the soil matrix and are not affected by sample interference but other properties depend on the soil structure and composition and for relatively undisturbed samples Only effective testing can be done. Several soil tests measure the direct nature of the soil, while others test "exponential properties" that provide useful information on the soil without directly measuring the desired properties.

IS can provide information necessary for assessment and monitoring of soil erosion (Shoshany et al., 2013). The effect of soil erosion can be explained by some features of soil surface condition and nature. These include chemical properties (pH, SOC, texture, free iron oxide, CaCO 3) and soil properties of physical (structure, texture, coarse debris), ground cover plants (fine granular minerals to coarse debris, plant debris And vegetation take into account the dimension of space and time (Pinet et al., 2006; Boardman, 2007). These soil spectral properties are readily available in the Mediterranean, where wide area bare fields are usually found (Bartholomeus et al., 2007; Gomez et al., 2012).

The soil category is a group of soils within subgroups that describe the physical and chemical properties that affect soil reactions for agricultural management and engineering applications. The main properties used to distinguish soil families include texture, mineralogy, pH, permeability, structure, concentration, local precipitation patterns, and soil temperature. Depending on the soil, the proportions of silt, sand, coarse debris such as gravel, pebbles, rocks etc. are also specified in the standards. Approximately 4,500 soil departments are recognized in the United States.
