Treating effluent while the sun shines

Handling the challenges of effluent management could become easier with a new product that allows dairy farmers to treat their effluent systems as a routine part of weekly milking shed maintenance.

The product comes in a liquid form and can be added to the effluent system through the existing drain in the dairy yard, says Richard Kettle of AHD Nutrition Division.

The core microbial technology is known as a photoautotroph, he says.

"In 'farmer' terms, this product has bacteria that activate and do their work when the sun is shining. Particularly effective in an effluent pond system where there is large reflective surfaces and sunlight.

"Biostack also holds onto micronutrients like nitrogen and phosphorus during dormancy. This means that when you pump effluent on the paddock or emerging crops you are taking the micronutrients to the plant, fostering additional growth."

The bacteria have a shelf life of three years when unopened; once the containers are opened it must be used within a six month period.

Kettle says Biostack users would notice a reduction in odour within two weeks of using the product and there will be little to no crusting on the pond surface. He says the product has the ability to break down both surface and bottom solids and effluent is easier to pump.

Kettle says farmers will notice an improvement in paddock performance after irrigation.

"Local experience has shown that some effluent ponds are under capacity and have massive sludge build up, even to the extent of a crusted top layer.

"A different approach with Biostack will be required in this instance. The product has shown to work under these heavier burdens, but the timeframe is longer. The photoautotroph bacteria will work incredibly well when it is utilised in a functioning manure pond system."

Biostack comes in two formulations, BiostackSL for sludge breakdown and non lactating period pond maintenance and Biostack AP for ongoing pond maintenance.
