During the last year I have started using diluted urine in the garden and on compost piles. I have several piles of compost. One of them is primarily leaves. I occasionally take leaves from this pile and add to the others if needed, but any excess leaves always go on this pile. Anyway, a friend was over at the house the other day and I mentioned using urine. He said that was good but to not us it on the leaves only pile. He didn't know the reason but said that he read or heard it somewhere that urine and leaves were a bad combination. Is that good advice or bad info?

I don't think it really matters. Urine is a concentrated source of nitrogen and has some phosphorus, potassium, etc., and using it on leaves should just make them decompose quicker and enrich the resulting compost's nitrogen content.

I've been using a "sawdust urinal" for nearly a year now, throwing the stuff into my regular compost heap.  It's great stuff!  Fill a 5 gallon bucket with sawdust or small wood chip or other loose organic material, relieve yourself as needed, and keep covered with a lid.  Empty when full.

The only problem would be from adding too much urine at one time.  If the pile smells like piss, add more leaves, or some dirt (soil), or finished compost, and mix well.

Check out Joe Jenkins "The Humanure Handbook" and website for more information on composting human "waste".

If you read the ingredient list on most commercial fertilizers you will see that most of the Nitrogen comes from a variety of ureas.  Applying urine to living plants will usually kill them (plus add too many salts to the soil).  Adding it to compost will both speed up the process and provide a more nutritional end product.

Sometimes I do water my compost pile with a urine/water mixture in a ratio of 1:10. That whay you can also water plants directly. But not often. It is still a very potent nitrogen source.

Before I started using the Jenkins sawdust toilet I used rabbit urine directly on plants.  I would dilute it by at least 50%. largely to extend it.  In winter with most plants dorment I use it on compost to make a hot pile.  I have yet to incorperate a urine diverter in my bucket system, and straining is a pain so do not use human urine that way, yet.  When working the garden I do not hesitate to pee on root plants or the base of  taller edible plants.  Never had a problem with burning or anything compared to other less urinated plants, only posative results.
 
I agree. Here's the link: http://stoves2.com
