"Leaf decomposition by bacteria ensures the release of nitrate ions into the soil."

Explain how other bacteria can reduce the availability of nitrate ions to plants?

Ok, what would I write for a two marker? There's a real lack of explanation in my text book!

Denitrifing bacteria such as Pseudomonas convert nitrate in the soil to N2 gas.

Although it seems like there should be more for two marks...

Denitrifying bacteria converts the nitrates in the soil into nitrogen gas and this is released into the atmosphere by a process called denitrification.

I disagree with the answers above; denitrification is the process by which nitrates are removed by denitrifying bacteria from the soil as they convert nitrates into nitrogen gas which is released into the atmosphere. I believe you're referring to nitrification whereby ammonia (produced during ammonification when saprobiotic bacteria decomposes organic matter into ammonia) and oxygen is combined by nitrifying bacteria such as nitrosomonas which produces the nitrites. The nitrites are converted into nitrates by nitrobacter.

Edit - just realised this post is from 2012 lmao
