North Carolina State University's College of Agriculture and Life Sciences (CALS) is the fourth largest college in the university [1] and one of the largest colleges of its kind in the nation, with nearly 3,400 students pursuing associate, bachelor's, master's and doctoral degrees and 1,300 on-campus and 700 off-campus faculty and staff members.
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.
A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
Biofertilizers are cost-effective and ecofriendly in nature, and their continuous usage has been shown to enhance soil fertility. [20] Besides promoting growth by multiple mechanisms , biofertilizers produces substances suppressing phytopathogens , guarding plants from abiotic and biotic stresses and detoxification of belowground pollutants ...
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.
It is a source of organic matter. Soil with higher levels of organic matter are less likely to compact, which improves the soil aeration and water drainage, as well as assists in supporting soil microbial health. [31] [11] It is sometimes credited as being the most widely use organic fertilizer and by volume is the top organic amendment.

Soil chemistry is the study of the chemical characteristics of soil.Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]
