Good clean muck
Good clean muck When manure is spread on fields, unhealthy
parasites can often find their way into streams and contaminate
them. Researchers looking for a solution to this problem are now
considering using a pasteurisation process which mixes recycled
materials, such as cement, lime kiln dust, coal ash, and gypsum
with the manure. This combination sets off a chemical reaction
which produces heat, ammonia, and a high-ph environment which could
kill the bugs infecting the streams. 2 OCTOBER 1999, P. 13
