Pollution. Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution (from a ...
Soil pollution can be caused by the following (non-exhaustive list): Contaminated by rocks containing large amounts of toxic elements. Contaminated by Pb due to vehicle exhaust, Cd, and Zn caused by tire wear. Contamination by strengthening air pollutants by incineration of fossil raw materials.
The environmental impact of agriculture involves impacts on a variety of different factors: the soil, water, the air, animal and soil variety, people, plants, and the food itself. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss ...
Potato field with soil erosion. In addition to the usual types of land degradation that have been known for centuries (water, wind and mechanical erosion, physical, chemical and biological degradation), four other types have emerged in the last 50 years: [12] pollution, often chemical, due to agricultural, industrial, mining or commercial ...
The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sectors contribute between 13% and 21% of global greenhouse gas emissions. [2] Emissions come from direct greenhouse gas emissions (for example from rice production and livestock farming). [3] And from indirect emissions.
Agricultural waste are plant residues from agriculture. These waste streams originate from arable land and horticulture. Agricultural waste are all parts of crops that are not used for human or animal food. Crop residues consist mainly of stems, branchs (in pruning), and leaves. [1] It is estimated that, on average, 80% of the plant of such ...
Modification of agricultural practices is a recognized method of carbon sequestration as soil can act as an effective carbon sink. [ 57 ] Soil management techniques include no-till farming , keyline design and windbreaks to reduce wind erosion, reincorporation of organic matter into the soil, reducing soil salinization , and preventing water ...
Soil compaction, also known as soil structure degradation, is the increase of bulk density or decrease in porosity of soil due to externally or internally applied loads. [1] Compaction can adversely affect nearly all physical, chemical and biological properties and functions of soil. [2] Together with soil erosion, it is regarded as the ...
