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 ...
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 .
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.
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.

According to a 2024 report: "39% of people living in America—131.2 million people—still live in places with failing grades for unhealthy levels of ozone or particle pollution." Analyzing data from 2020 to 2022, the American Lung Association found the number of people living in counties with a failing grade for ozone declined, this year by 2 ...
If so, a soil ball 12 to 14 inches in diameter and 10 or 12 inches deep would be ideal. Use a sharpshooter spade to cut the roots and form the ball of soil but do so gently and patiently.
One third of the globe's land has degraded soil; [1] especially the tropics and subtropics with around 500 million hectares. [1] Soil degradation occurs due to physical, chemical, and biological forces. [5] These forces can be natural and anthropogenic. [5] [1] Tilling is a physical example which causes erosion, compaction, and decreased ...
