Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.
This observation follows the concept of resource competition and fitness maximization. [ 9 ] Due to the law of the minimum paradoxes, if we observe the Law of the Minimum in artificial systems, then under natural conditions adaptation will equalize the load of different factors and we can expect a violation of the law of the minimum.
Although broader and more generally useful concepts of soil were being developed by some soil scientists, especially Eugene W. Hilgard (1833–1916) and George Nelson Coffey (1875–1967) in the United States and soil scientists in Russia, the necessary data for formulating these broader concepts came from the field work of the soil survey.

A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
In terms of soil chemistry, it places particular emphasis on plant nutrients of importance to farming and horticulture, especially with regard to soil fertility and fertilizer components. Physical edaphology is strongly associated with crop irrigation and drainage. Soil husbandry is a strong tradition within agricultural soil science.
William Albert Albrecht (September 12, 1888 – May 19, 1974) [1] [2] chairman of the Department of Soils at the University of Missouri, was the foremost authority on the relation of soil fertility to human health and earned four degrees from the University of Illinois at Urbana–Champaign.
Granger’s family and team have since confirmed that the 81-year-old rep is indeed at an independent living facility but denied reports that she is residing within the facility’s memory care ...
Soil acidification refers to the process by which the pH level of soil becomes more acidic over time. Soil pH is a measure of the soil's acidity or alkalinity and is determined on a scale from 0 to 14, with 7 being neutral. A pH value below 7 indicates acidic soil, while a pH value above 7 indicates alkaline or basic soil.
