Concentrations of carbon and nitrogen were significantly higher in these ponds than farther upstream of this site. These results indicate that the beavers' activity contributes to reducing the effects of soil erosion and pollution in agricultural landscapes. [15]
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

As litter decomposes, nutrients are released into the environment. The portion of the litter that is not readily decomposable is known as humus. Litter aids in soil moisture retention by cooling the ground surface and holding moisture in decaying organic matter. The flora and fauna working to decompose soil litter also aid in soil respiration.
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 .
[1] [2] [3] Environmental conditions play a key role in defining the function and geographic distributions of plants. Therefore, when environmental conditions change, this can result in changes to biodiversity. [4] The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6]
As part of sustainable development, it pays close attention to preserving limited resources, reducing waste, and preventing air, water and soil pollution. Compost, fertilization, integrated pest management , using the right plant in the right place, appropriate use of turf and xeriscaping (water-wise gardening) are all components of sustainable ...
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
[9] [10] It is also provides many benefits to the ecosystems it is a part of, for example it provides valuable nutrition for grazing animals and helps prevent soil erosion. [ 11 ] [ 4 ] Leadplant may also be used in landscaping and gardening purposes due to its nitrogen fixing qualities and ability to help prevent erosion. [ 12 ]
