Measuring Nitrogen Levels

Hello,

We have built several biogas digesters at Living Energy Farm (.org). We recently completed a new digester with solar heat in a 2000 gallon tank. We are using farm waste and human waste. I am wondering if anyone has any suggestions about how to measure the nitrogen levels in our tank (or from the effluent?) I am wondering how much human waste we should put in there. We could have 12 people putting their waste in there daily, but I am not sure if that is appropriate. Any advice welcomed.Thanks,

Alexis
