Update on the whole-stream nitrogen additions

This year we're adding nitrogen to the two cold and two warm streams. Six hundred kilos of ammonium nitrate fertilizer will do the job, delivered by the same float-valve drippers we used last year to add phosphorus. 



It's now mid-June and still early days for our nitrogen additions, but we're already playing spot the difference. Here are two shots taken two days ago of one of our warm streams. The left photo is just upstream of the nitrogen dripper, while the other shot is just downstream. Note the particularly lurid green clumps of Cladophora that start directly below the dripper.


Our isotope additions to the four streams will start in the next few days (depending on weather!), so watch this space.
