Proposed rule for farms aims to improve Lake Erie

Ohio's lawmakers are moving toward taking on the algae that has plagued Lake Erie in recent years.

New legislation recently approved in the state House would ban farmers in much of northwestern Ohio from spreading manure on frozen or saturated fields.

Farmers also would need to hold off if are in the forecast. Another provision would set new rules on the dumping of dredged sediment in the lake.

Both the and the dredging are thought to contribute to the that produce the kind of dangerous toxins that left residents around Toledo and in southeastern Michigan without water for two days in August.

The proposals addressing the algae problem still need approval from the Ohio Senate and Ohio's governor.

Anaerobic digestion and nutrient management programs are absolutely necessary. New organisms living in the high mesophilic range produce up to 700 Btu/ft3 of biogas. The residue is nutrient stabilized for the solids, with cellulosic materials serving as substrates for the beneficial bacteria.

Urine and excess Nitrogen go through a lagoon nitrification/denitrification process, and return it to the land, eliminating the pollution from the excess.

Every seven cows produce sufficient methane to supply a complete household continuously.

We have been doing this since my thesis started in 1980.
