The enrichment factor can also be used to talk about the level of radioactive isotopes in uranium, or the level of minerals in soil. [1] The same concept is used in Bioinformatics for gene analysis, to measure the added value of a search tool over another one or over the homogeneous distribution in the genome population.
Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order within soils.
Food enrichment specifically means adding back nutrients lost during food processing, while fortification includes adding nutrients not naturally present. [1] Food manufacturers and governments have used these practices since the 1920s to help prevent nutrient deficiencies in populations.
Burial of food can preserve it due to a variety of factors: lack of light, lack of oxygen, cool temperatures, pH level, or desiccants in the soil. Burial may be combined with other methods such as salting or fermentation. Most foods can be preserved in soil that is very dry and salty (thus a desiccant) such as sand, or soil that is frozen.
Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment.

Biocrust influences a soil's microtopography, carbohydrate content, porosity, and hydrophobicity which are the major contributing factors to soil hydrology. The relationship between biocrust and soil hydrology is not fully understood by scientists. It is known that the biocrust does play a role in the absorption and retention of moisture in the ...
Intensive farming methods to satisfy high food demands with high crop yields and growing crops in monocultures can deplete the soil nutrients and damage the soil microbiome. These factors can affect the consistency and quality of the soil resulting in increased erosion. Surface runoff from farm fields is a type of nonpoint source pollution.
food security - food produced in sufficient quantity to meet the full requirements of all people i.e. total global food supply equals the total global demand. For households it is the ability to purchase or produce the food they need for a healthy and active life (disposable income is a crucial issue).
