Agricultural runoff by scarcity, migration contains harmful components of fertilizers and pesticide causing huge impact on environment. [Diagram showing runoff process with eutrophication and local body impact] Big O landslide: Agricultural runoffEnvironmental Pollution 1) Eutrophication of lakes, river streams (algae growth, water BOD, COD disrupted, i.e. biological oxygen demand) 2) Invasive Alien species can also grow 3) Marine life that breathes, consume food and water also affected due to chemical components
4Microplastics in the water bodies and environment sources. 5) Runoff when evaporated leads to sedimentation of saline deposits causing soil salinity, affected by 'calcification' 6) Leaching of runoff in ground can contaminate groundwater 7) Destruction of ecological characteristic of land, waterbodies 8) Finds itself in 'food chain' and thus 'residues' can be 'bioaccumulated' causing human environment damage. Measures to mitigate the impact: 1) Creation of 'embankments' so that runoff can be collected / stopped by step cultivation 2) Channeling of Agriculture land so that water collected in drainage basins and not fresh source.
3Collection of runoff and treatment of water 4) Using misconfiguration to reduce the quantity of runoff (almost negligible) 5) Promoting Organic farming, Natural farming (Subash Palekar zero budget) (ensure runoff will have no chemical beneficial soil features as herbicides as leaves and residues) 6) Awareness among farmers to use only optimum amount and not overuse by Ideal NPK ratio is inverted with overuse of urea. Thus, above steps can be taken to preserve ecological sanity of ecosystems and mitigate harmful effects of runoff.
