The headline is a bit silly: Sustainable Fertilizer: Urine
And Wood Ash Produce Large Harvest. In fact the article
that follows says that urine alone produces a bigger

But the scientific paper says that the dry biomass from
urine+ash is significantly bigger than from urine alone. So
the "bigger harvest" you mention is mostly water.
