I store urine in closed big plastic jugs till application , but sometimes it is a couple weeks before I transfer from the separator toilet, which is not sealed. I just wasn't sure how quickly the volatilization happened.<br />Steve Carrowhttps://www.blogger.com/profile/11706114439618856525noreply@blogger.comtag:blogger.com,1999:blog-471462053585171190.post-57610057960980631572021-01-21T10:29:47.024-08:002021-01-21T10:29:47.024-08:00"There are questions on how much to dilute be..."<i>There are questions on how much to dilute before application</i>"<br /><br />One problem is that urine alone is not a balanced fertilizer, being primarily nitrogen. If that's all you use, you'll end up with a lot of foliage, and not so much fruit.<br /><br />Fortunately, a simple solution exists. If you heat with wood, you have wood ash, which has no nitrogen, but is high in potassium and phosphorous.<br /><br />We make a slurry with wood ash and water, stir it up well, and let it sit until the ash settles.<br /><br />Then carefully decant the liquid part and mix it with urine. But that is still pretty potent, at about 10:10:10, which may "burn" plants if you apply it directly. It is also very basic, which will disturb the pH balance of your soil if used directly.<br /><br />So dilute that about 1:9 with water, and you'll have a lovely 1:1:1 fertilizer that can be used full-strength as irrigation water. (If your soil is already basic, add a bit of vinegar before using.) We pump it through drip line to apply it directly to plants.<br /><br />"<i>how to minimize loss of nitrogen from ammonia volatilization</i>"<br /><br />Sealed containers keep the nitrogen in! It will slowly change to urea, which is still bioavailable as fertilizer.<br /><br />We use 200 litre (55 gallon) drums with tight-fitting lids or bungs, and have used it several years after "bottling" it.Jan Steinmanhttp://www.ecoreality.orgnoreply@blogger.com
