Soil can harbor pathogens that cause diseases in humans. Soil-borne bacteria may lead to gastrointestinal, wound, skin or respiratory illnesses. Systemic fungi acquired from contaminated soil can also cause disease. However, healthy soil with high biodiversity plays an important role in controlling pathogen populations and reducing disease outbreaks. Dermal exposure to soil contaminants can cause skin diseases and systemic effects if the contaminants enter the bloodstream. Soil is a finite resource critical to human health, as it enables food growth and supports air and water quality. Without healthy soil, food cannot be grown.

2. Soil borne disease in humans
In addition to tetanus, anthrax, and botulism,
soil bacteria may cause gastrointestinal,
wound, skin, and respiratory tract diseases.
The systemic fungi are largely acquired via
inhalation from contaminated soil and near-soil
environments.

3. Soil borne organisms improve human life
Healthy, biodiverse soils are crucial for
human health and wellbeing from several
reasons, for example: biodiversity has been
shown to be important in controlling
populations of pathogens; healthy, well-
covered soils can reduce disease
outbreaks; carbon-rich soils may also
reduce outbreaks of human and animal
parasites.

4. Infectious diseases commonly spread
through the direct transfer of bacteria, viruses
or other germs from one person to another.
This can happen when an individual with the
bacterium or virus touches, kisses, or coughs
or sneezes on someone who isn't infected

5. Dermal exposure to soil contaminants can
cause skin diseases, such as dermatitis
caused by irritation or allergies, hives, acne or
even cancer. But systemic effects can also be
observed if the skin barrier is bypassed, such
as when contaminants enter and spread
through the circulatory system.

6. Soil is a finite resource, meaning its loss and
degradation is not recoverable within a human
lifespan. Soils affect the food we eat, the water
we drink, the air we breathe, our health and
the health of all organisms on the
planet. Without healthy soils we wouldn't be
able to grow our food.
soil fertility affect humans

7. Heat. Heating the soil is very effective and
the soil can be used immediately after
cooling, unlike chemically treated soil. Many
plant pathogens are killed by short
exposures to high temperatures. Most plant
pathogens can be killed by temperatures of
140°F (60°C) for 30 minutes.
