III. Determination of Earth Resistivity in Multilayer Soil Model Uniform soil model (single-layer soil model) and the two-layer soil model are the most commonly used soil models for resistivity analysis. When there is a little variation in apparent resistivity, that model can be considered as a homogeneous/ uniform soil model.

Soil compaction is a major global issue associated with modern, mechanical agriculture. The use of heavy machinery and other modern agricultural approaches can have significant impact on soil and soil based processes. Soil compaction is defined as a process where soil grains are rearranged to reduce void space, thereby increasing bulk density.

soil moisture (w S) at shallow soil depths (approximately 2- 5 cm) (Newton, Black, Makanvand, Blanchard, & Jean, 1982; Raju et al., 1995). This is due to the fact that the soil moisture dependence of the transmission coefficient across the air-soil interface predominates the soil moisture dependence of the total energy originating from the soil

nutrients. Particularly, soil air is needed by many of the microorganisms that release plant nutrients to the soil. An appropriate balance between soil air and soil water must be maintained since soil air is displaced by soil water. Achieving Balanced Nutrition Several nutrients compete with each other over uptake by the plant, so keeping

This issue of Soil Horizons shows how our traditional approaches to soil science, collecting data, research - and even the way we view soil - have changed. Rapid advances in technology are opening many new soil research opportunities, and these advances are combining with the

Soil organic matter content is key for a healthy and high-quality soil. This brochure highlights methods to improve soil organic matter content which can help ensure adequate soil functionality and soil fertility. It also offers a number of solutions for common soil challenges, which are especially critical in Mediterranean regions.

SUGGESTED SOIL TYPES AND TESTS Soil Selection Soils for the soil microbiology section should be chosen to represent as diverse a range of soil types as possible. Some suggestions for locating diver-gent soils include: Plowed agricultural land and adjacent, unplowed land. Mountain soil and valley soil.

Laboratory Services tests soil samples to determine how effectively the soil can grow the crop. By measuring the soil’s pH level and plant-available nutrients, lime and fertilizer recommendations can be given. Specific crops require specific nutrient levels. The soil test is divided into four main sections, as shown on the Sample Soil Test .

The Munsell Soil Color Chart is the only system that should be used to describe soil colors. When describing soil colors, soils should be moist (not dripping wet) and should be colored in the field soon after opening up the soil pit. Hold the soil in the opening next to the color chip to compare the color. The soil color is described by hue (the

acidic, respectively. A soil with a pH of 6.0 is ten times more acidic than a soil of pH 7.0. Changes in soil pH dramatically affect the availability of nutrients to growing crops. The pH meter is the preferred method for determination of soil pH. The flow of basic image processing techniques for determination of pH in the soil is shown below:

Hence, soil quality cannot be assessed with one variable but with a combination of these factors (Barrios et al, 2006) showing the state of soil (Dumanski and Pieri, 2000). Soil microbial functional diversity is a good indicator of soil quality, as it is integrative of
