Nutrient Imbalance

Nate Storey has done it again!

Figuring out nutrient imbalance is in my opinion the most difficult thing about aquaponics.  Nate really lays it out in an easy to understand method for us to determine a course of action when our plants begin to look a bit peeked. I would post the link  to the KEY he has developed for diagnosing these problems right here, but I feel that you should go to Nates site and find his offer.   When asked to register just do it.  You will be pleasantly surprised.

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.
