In this series for Thursdairy, we talked to Dr Laura Stocker, Dairy Executive officer at WA Farmers and conservation dairy expert about how dairy-effluent can create a win-win-win scenario for the farmer by efficiently returning nutrients to pasture, protecting waterways from pollution, and saving farmers money on fertilizers.
Every living thing has to process food for nutrition. However, we can’t use 100% of everything we eat and thus we have waste created from digestion.
Dairy cows are no different.
The demands of modern dairy requires cows in large numbers to create a volume of milk that is economic for the farmer.
Thus, when you put a lot of cows together you get A LOT of waste.
This effluent, mainly a mixture of manure, urine, and wash-down water isn’t the most appealing brew at first glance.
But… its packed-full of nitrogen, phosphorous, potassium and other micro-nutrients.
The question arises, what do you do with it all?
Tune in next week as we follow the flow of this story!
