There is a huge amount of guidance out there.However, we thought it would be useful to include on this page some key points in relation to nutrients, sediment and pesticides.


Nutrients and sediment


Diffuse pollution can be in the form of sediments and nutrients such as nitrates and phosphorus.These nutrients can result from agriculture and also a number of other sources such as sewage treatment works, transport and industrial sites and can lead to the nutrient enrichment, and oxygen depletion of a watercourse which can have adverse effects on the aquatic ecosystem.††


Some basic actions include:


-        Ensure manures are used appropriately by analysing what nutrients are present so that land is not overloaded with nutrients that can leach or runoff easily.

-        Maintain your soil structure at a good standard (see the EA Think Soils booklet for further advice), this will promote rain infiltration into soil which in turn will avoid soil runoff and erosion and therefore the sedimentation of watercourses will be reduced.


Avoid compaction from machinery and livestock by reducing the number of passes carried out over land, reducing tyre pressures to spread the load weight and reducing stock numbers on vulnerable fields that are close to watercourses.



Keep key pesticide handling in mind, including:


-        Avoid spraying/pelleting within 6 metres of all watercourses

-        Avoid spraying/pelleting when heavy rain is forecasted in the next 3 to 5 days

-        Avoid spraying/pelleting when field drains are flowing

-        Clean up spills quickly and responsibly by disposing of waste correctly i.e. donít wash spills down the closest drain

-         Wash down sprayer equipment in fields where possible

-         Brush down pellet applicators in fields away from watercourses and gateways to avoid carrying pellets onto hard surfaces where runoff can occur easily.
