In 1978, Swiss soil biologist Dr Otto Buess wrote an essay "The Health of Soil and Plants" which largely defines the field even today. The underlying principle in the use of the term "soil health" is that soil is not just an inert, lifeless growing medium, which modern intensive farming tends to represent, rather it is a living, dynamic and ...
This makes it crucial that the fields have enough nitrogen in the soil to grow a prosperous crop. [5] However, excess nitrogen in the soil can also be harmful to potato production, influencing how well the roots are able to develop, and delays can occur in tuber initiation during the tuberization stage of potato growth.
Ultisol, commonly known as red clay soil, is one of twelve soil orders in the United States Department of Agriculture soil taxonomy. The word "Ultisol" is derived from "ultimate", because Ultisols were seen as the ultimate product of continuous weathering of minerals in a humid, temperate climate without new soil formation via glaciation .
Although the United States has many sites with contaminated soils, it has been a leader in defining and implementing standards for cleanup. [4] Each year, thousands of sites complete soil contamination cleanup, some by using microbes that “eat up” toxic chemicals in soil, [5] many others by simple excavation and others by soil vapor extraction, air stripping, or solvent extraction, with ...
The darkened surfaces of biological soil crusts decreases soil albedo (a measure of the amount of light reflected off of the surface) compared to nearby soils, which increases the energy absorbed by the soil surface. Soils with well-developed biological soil crusts can be over 12 °C (22 °F) warmer than adjacent surfaces.
The soil is very light, so windbreaks are necessary to protect these fields in dry weather. It also can catch fire and burn underground for months. Oxidation also removes a portion of the soil each year, making it progressively shallower.

Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
