“Innovation” is a buzzword thrown about to the point of cliché. What it is varies with the circumstance.
For tech professionals, innovation could be an updated app or a streamlined solution. For teachers, it might be the newest way to engage students remotely. For those in health care, it may be a vaccine or more-effective treatment.
On dairy farms, innovation can look like … entomological wastewater filtration and effluent subsurface drip irrigation. Neither are buzzwords. Both are examples of how dairy is innovating its way toward a more sustainable future.
Royal Dairy in Royal City, Washington, wanted to enhance its waste-management system and reduce GHG emissions. Seeking solutions, Austin Allred, owner of Royal Dairy and a member of Northwest Dairy Association, piloted and adopted the BIDA® System developed by BioFiltro. The international wastewater filtration company uses worms within a passive aerobic system to clean wastewater from the dairy for irrigation. By investing in this technology, Royal Dairy has reduced its Total Suspended Solids (TSS) by 99% and reduced total Nitrogen (TKN) by 83%. As an added benefit, it also creates a rich fertilizer from the worm castings.
Another sustainability solution is found at De Jager Dairy North and California Dairies Inc., member McRee Dairy, both near Chowchilla, California, where drip irrigation is leading toward a future of better harvests and reduced emissions.
The two dairies partnered with Israeli company Netafim and Sustainable Conservation to develop and test a sub-surface irrigation system that delivers liquid dairy cow manure as a fertilizer close to the crop’s root system. This results in needing up to 35 percent less water while maintaining or even increasing crop yields in addition to reducing irrigation-related greenhouse gas emissions by 70 percent – saving costs and building resilience against droughts projected to worsen with climate change.
