What are the negative impacts of agriculture on soil? Name two ways in which
these impacts can be reduced
Answers
Answer:
Soil Tillage, Climate Change and Soil Carbon Sequestration
Unsustainable agricultural techniques which cause erosion, such as excessive tillage, and which do not improve soil health (e.g., soil microbes and organic matter), hasten the release of carbon dioxide into the atmosphere.
Answer:
Soil and plant health is interrelated with animal/human health. Whatever pollutants and contaminants added incidentally to soil may affect the plant -animal/human system.Advanced machinery and equipment and improved plant varieties are used,commercial fertilizers,pesticides,animal manures etc are added to soil every season/year.These practices over time may affect the soil health and also may affect the water quality in wells and near by water bodies.The soil biodiversity of the area may also get affected.
Prevention
soil compaction, deep root removal, tillage, synthetic fertilizers, insecticides, fungicides, and herbicides all damage the soil by reducing air pore size, altering drainage, erosion, eliminating healthy populations of mycorrhizae and beneficial worms, insects and bacteria, as well as providing a good environment for pest species to thrive without natural competition.
