põllumajandussaasteained

Põllumajandussaasteained refers to substances originating from agricultural activities that can negatively impact the environment. These can include excess nutrients, pesticides, herbicides, sediment, and animal waste. Nutrients, particularly nitrogen and phosphorus from fertilizers and manure, can leach into waterways, causing eutrophication, which leads to algal blooms and oxygen depletion. Pesticides and herbicides, used to control pests and weeds, can contaminate soil and water, harming non-target organisms and potentially entering the food chain. Sediment runoff from cultivated fields can silt up rivers and lakes, affecting aquatic habitats. Animal waste from livestock operations can also contribute to nutrient and pathogen pollution. Practices such as intensive farming, improper manure management, and inadequate erosion control can exacerbate the problem. Addressing põllumajandussaasteained involves implementing sustainable agricultural techniques like crop rotation, cover cropping, integrated pest management, and precise fertilizer application. Conservation measures such as buffer strips along waterways and improved drainage management are also crucial.
