Techniques to pervert Eutrophication 

 The main causes  of most of the algal bloom peaks are greatly attributed by the poor agricultural techniques used. Due to these poor practices he nutrient enrich run off can enter water bodies an encourage algal bloom peaks.This issue places a great impact on communities' fishing, tourism and water sources where contamination is imminent.  some techniques to minimize  the amount of run off:

• Terracing, a well known  agricultural technique can be used, where the sloping lands are cut in sequence into flat platforms where they would now plant crops on. This reduces the runoff from irrigation as water is not given as much energy flow faster on flat land than on slopes making it easy to reduce the amount of runoff.

• Contour farming like terracing minimizes the amoun to runoff on a slope, this is done by rather than attempting to growing crops up the slope crops are grown with the contour or across a perpendicular plane.
  

• The reduction in the amount or rather keeping to recommended dosages of fertilizer can help stop the amount of nutrient in the runoff where the soils are not over saturated with these nutrients hence making it easy to wash away large amounts of nutrients in the runoff.      

• The use of Crop Rotation where different types of crops are planted on the same plot of land is beneficial to the soil this way the soil remains strong and fertile as different nutrtients in is is used and replaced making it less susceptible to runoff and erosion. 

• In agriculture the management og livestok is key therefore whem leaving livestock to graze on lands it is key not to allow them to overgraze. this is because overgrazing increases soil erosion as the soil becomes more exposed to the elements. Along with the obvious erosion of the soil all the added nutrients that these animals would have added to the soil with their "natural fertilizer" would be easily washed away as the now exposed soil is now susceptible to any water action that may affect the soil.
