Effective approach to effluent control in intensive animal manaqement

摘要

Effluent management has become a major concern on Australian farms where animals are confined for any purpose. Recognising this, BioAg Pty Ltd, a Riverina based biological fertiliser manufacturer, began to work on ameliorating the problem two years ago, first in the dairy sector where farmers have a legal obligation to contain, manage and dispose of livestock effluent within property boundaries in a manner which prevents the pollution of surface and groundwater. Moreover, increased herd size and urban encroachment have brought the issue under much greater public scrutiny. Trials have shown that the digestion product Digest-it, liquefies the sludge in dairy ponds and lagoons and eliminates odour by fostering aerobic digestion of organic matter.
