Family founded, family operated.

Dairy farming has been a De Jong tradition since Donald’s parents, William and Ina, came to America from Holland over 60 years ago.


The Varcor system transforms cow poop into clean water and dry organic fertilizer, reducing greenhouse emissions and creating a closed-loop farm system.

It will revolutionize animal agriculture forever, as it provides a clean water supply and natural fertilizer that’s economically viable and not dependent upon the petrochemical industry. Not only does the Varcor create clean water, it also generates dry NPK powder that also contains all the micronutrients that plants require. It’s a game-changer, indeed.
