Nitrogen cycle

Nitrogen cycle- how it works

Bacteria process 1- Ammonification

Ammonification-enzymes

Nitrification

What type of reaction is nitrification

Denitrification

Nitrogen fixation

Azotobacter

Rhizobium

Last one on nitrogen fixation I promise

Plants without mutualistic nitrogen fixing bacteria...

Nevermind I lied- more nitrogen fixation

Nevermind I lied- more nitrogen fixation p2

Non biological processes that impact the nitrogen cycle

Human impact on nitrogen cycle

Ploughing

Draining land/ artificial nitrogen fixation

Large amounts of animal waste

Slurry/ biosolids

Fields of legumes

Effects of fertilisers on habitats

Problems caused by excess nitrates in soils

Problems caused by nitrates leaching into rivers-

Fertiliser leaching P2

Fertilising leaching p3
