Frogs have an anti bacterial bio film on their skin

Frogs have an anti-bacterial bio-film on their skin.  In fact there is an ancient Russian practice of placing a frog in milk to keep it fresh longer.    My bioponic systems are teaming with frogs and tadpoles.  Nitrification continues but it makes me wonder if Im deriving a special advantage from the frogs that may help prevent diseases such as bacterial canker, soft rot, leaf spot, and wilt.  I rarely experience these problems, so maybe its a gift from the frogs.  At night their singing it very loud but I like the sounds of nature..

Using Humona human urine for Fertilizer

When I read this article I felt validated.  Ive been promoting the use of urine and weed tea as a replacement for fertilizer created from petroleum.  Urine contains nitrogen and phosphorous as well as many other trace elements necessary to plants.

In order to sanitize urine, it can either be stored for 30 days in a sealed tank at room temperature, or heated for 30 minutes in a solar pasteurizer.

I work at home so I was able to save about 70% of the urine I produced, and in 2013 I easily filled a 55 gallon drum.  This will drum remained sealed for at least 3 months. 

Since the urine is added the systems water and the water wickes up through the soil I see no possibility of contamination, but others may not feel comfortable so I will let the humona (human urine) age for their peace of mind.
