B—Lancaster Farming. Saturday, June 19.1971 Speakers See 'Recycled Nutrients' as Pollution Solution The concept of waste recycling was the center of attention at the Wednesday afternoon session of the Pennsylvania Poultry Fed eration meeting Dr. Charles L Hosier, dean of earth and mineral sciences. Penn State University, began the dis cussion with a description and slide preesntation of how only minor changes in atmospheric conditions could lead to serious changes in rainfall in the U S , leading to drought and severe crop reductions He indicated that manmade and growing pol lution levels in the atmosphere can lead to disastrous weather conditions, including drought He was particularly critical of state laws which ban study of weather He said this study may be necessary in the future to off set some of the problems which ere being caused by growing levels of pollution Pointing to other countries which once had highly developed end wealthy civilizations, Dr Hosier said the same thing could happen to the U S. if the environ- Is your Insurance earning its keep Is it up to date?

Dr. Howard Zindell, Michigan State poultry science depart ment, spoke on work in Michigan to convert animal waste into an important protein source Predicting that within five to 10 years “every state will have a law against spreading manure in its present form on the land,” Dr Zindell said a feasible alter native now appears to be to dry the manure and recycle it in poultry and animal operations. Studies show that dried poul try waste has about 33 pei cent crude protein which breaks down into about 12 per cent usable protein for poultry, a figure still higher than corn Experiments so far show that best gams are achieved from a combination of one-half urea and one-half recycled nutrients, he said The process is called “re cycled nutrients” because it de scribes without offending, he ex plained.

He indicated that pre-drying, such as the work being done at Cloisterdale Farms at Ephrata, is a help, since wetter manure reduces the capacity of the dry er.
