    en.wikipedia.org/wiki/Environmental_impact_of...

    The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.

  3. Agricultural pollution - Wikipedia

    en.wikipedia.org/wiki/Agricultural_pollution

    Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts. Bad management practices include poorly managed animal feeding operations, overgrazing , plowing, fertilizer, and improper, excessive, or badly timed use of ...

    Such management may help attenuate the undesirable cascading effects and eliminate environmental Nr accumulation. [1] Human activities dominate the global and most regional N cycles. [36] N inputs have shown negative consequences for both nutrient cycling and native species diversity in terrestrial and aquatic systems.

  7. Environmental impact of pesticides - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Other agrochemicals, such as fertilizers, can also have negative effects on the environment. The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas.

  8. Eutrophication - Wikipedia

    en.wikipedia.org/wiki/Eutrophication

    Manmade, or cultural, eutrophication occurs when sewage, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment. [3] Such nutrient pollution usually causes algal blooms and bacterial growth, resulting in the depletion of dissolved oxygen in water and causing substantial environmental degradation. [4]

  9. CO2 fertilization effect - Wikipedia

    en.wikipedia.org/wiki/CO2_fertilization_effect

    Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]
