Another day, another defense of biosolids. #sewage sludge

I use biosolids and love it -especially on our tomatoes. We've studied the science of biosolids for decades alongside demonstrating safety. They even have amazing protective powers (http://biosolidsgrow.blogspot.com/2011/08/sewage-sludge-has-super-powers-that.html). They are the a local, sustainable, renewable option (critical as we are running out of phosphorus) alternative to synthetic (including petrochemical) fertilizers. Biosolids that go back to farms and gardens also help fight climate change by sequestering carbon that can generate carbon credits (not true when it's burned as a fuel). It is critical to understand that presence does not mean the plants will uptake that material (peer-reviewed science here showing that use of biosolids REDUCES metals uptaken in plants compared to control (that took up More metals!) http://biosolidsgrow.blogspot.com/2011/08/sewage-sludge-has-super-powers-that.html. Finally, if you think buying something else without sewage sludge in it is the answer, think again. Here you'll see that biosolids compost has the same amount stuff as other organic amendments - actual data included (http://biosolidsgrow.blogspot.com/2011/08/what-contaminants-lurk-in-sewage-sludge.html). But, biosolids has lots and lots of good stuff inside too cause it comes from us and all the vitamins and great food that we eat. The plants love vitamins and grow like crazy cause it's good stuff!  Even has probiotic powers!
