求翻译：All across the country in the 80s,similar projects got underway, yet the focus was not necessarily on soil organic matter and certainly not on organic farming. The concept beneficial re-use began to be used widely; around the same time sludge was re-coined biosolids, and the national Waste water Federation became the Water Environment Federation. Not surprisingly, from where we stand now, many look back to the 80s as a time of enthusiasm as matched only by confusing and poorly informed efforts. It is a droll reminder of the recent small beginnings of the era that a researcher at a New England Department of Agriculture had to call all around the Northeas to discover if any laboratories could perform C:N ratio analysis in order to formulate a compost mixture(personal communication, Bill Seekins).是什么意思？
