To determine the type of soil found in a farm/field, and a sand dune, we need to understand the concepts of zonal, azonal, and intrazonal soils.
Zonal soils are those that have developed in response to the dominant soil-forming processes of a specific climate and vegetation. These soils typically have well-developed soil horizons and are influenced by factors like rainfall, temperature, vegetation, and topography. Zonal soils are further classified into various orders, such as Alfisols, Spodosols, and Aridisols, based on their specific characteristics.
Azonal soils, on the other hand, are found in areas where the soil formation processes are not strongly influenced by the prevailing climate and vegetation. They typically occur in areas of recent geological activity, such as floodplains, alluvial fans, and glacial deposits. Azonal soils do not exhibit the typical soil horizons seen in zonal soils and have different characteristics, such as high levels of organic matter or lack of distinct soil layers.
Intrazonal soils are intermediate between zonal and azonal soils. They occur in localized areas within a zonal soil region, where special conditions exist that deviate from the dominant soil-forming processes. Intrazonal soils may result from factors like excess moisture, poor drainage, or specific parent materials. They often exhibit distinct characteristics that are different from the surrounding zonal soils.
Now, applying this knowledge to the specific cases mentioned:
1. Farm/Field soil: The type of soil found in a farm/field is most likely zonal soil. It develops over time under the influence of climate, vegetation, and other factors such as human activities (e.g., cultivation, irrigation, and fertilization). The specific soil order would depend on the prevailing conditions in that area, such as temperature, rainfall, and vegetation.
2. Sand dune soil: Sand dunes are typically associated with desert or coastal environments. The soil found in sand dunes is generally considered azonal. These soils are often formed from wind-blown sand deposits and lack the distinct soil horizons found in zonal soils. They have unique characteristics, such as high sand content, low organic matter, and limited nutrient availability due to leaching caused by wind and minimal vegetation cover.
Remember that soil classification can be complex, and the specific soil types can vary based on the region and local conditions. Soil experts and soil surveys conducted by agricultural and geological institutions are valuable resources for obtaining accurate information about soil types in specific areas.
