Dear Tia A, There are several Studies conducted on using the Domestic Sludge as Soil Conditioner or by adding some NPK (Nitrogen, Phosphorous and Potassium) to give it complete Fertilizer Qualities. Many part of the world it is being used after some basic treatments: A few excerpts are for your consideration as follows; A Joint Study/Research Conducted by: Nuclear Institute of Agriculture (NIA), Tandojam, Sindh, Pakistan National Centre of Excellence, University of Sindh, Jamshoro, Sindh Pakistan, Department of Botany, University of Karachi, Karachi, Pakistan. "The high nutrients and organic matter contents of sewage sludge make it an excellent fertilizer to enhance soil fertility and crop production. However, presence of metals is a major problem for such a utilization of sludge. It may be concluded that application of sewage sludge was good for improving crop yield but it was also a source of metals. Therefore monitoring of metals, in soils as well as in plant parts, should always be carried out in case of continuous use of sewage sludge." [Reference: Pak. J. Bot., 39(7): 2511-2517, 2007.] ========================== By USEPA, please read Fertilizers Made From Domestic Septage and Sewage Sludge (Biosolids) on the following link: http://www.epa.gov/agriculture/tfer.html Another Detailed Link http://nepis.epa.gov/Exe/ZyNET.exe/30004O9U.TXT?ZyActionD=ZyDocument&Client=EPA&Index=1995+Thru+1999&Docs=&Query=&Time=&EndTime=&SearchMethod=1&TocRestrict=n&Toc=&TocEntry=&QField=&QFieldYear=&QFieldMonth=&QFieldDay=&IntQFieldOp=0&ExtQFieldOp=0&XmlQuery=&File=D%3A%5Czyfiles%5CIndex%20Data%5C95thru99%5CTxt%5C00000003%5C30004O9U.txt&User=ANONYMOUS&Password=anonymous&SortMethod=h%7C-&MaximumDocuments=1&FuzzyDegree=0&ImageQuality=r75g8/r75g8/x150y150g16/i425&Display=p%7Cf&DefSeekPage=x&SearchBack=ZyActionL&Back=ZyActionS&BackDesc=Results%20page&MaximumPages=1&ZyEntry=1&SeekPage=x&ZyPURL And Another Link http://www.fao.org/docrep/T0551E/t0551e08.htm I hope this details are sufficient for your satisfaction.
