What our customers say
More milk from our own forage, without the hard work
“Our old silos were worn out, and covering them always took a lot of effort. With the new bunker silo and the Agridek system, that tough job is a thing of the past — we finally have the labour-saving solution we were looking for.”
Dairy farm Joustra – Buitenpost
Consistent quality for 1,200 dairy goats with smart forage storage
With 2,500 silage bales in our organic system, we needed a new storage solution. The lasagna pit saves both space and money — and ensures a consistent feed supply. The design was well thought out, which gave us confidence from the start.
Goat farm Trix
Effortless ensiling — in both small and large quantities
For our medium-sized farm, this system is ideal. We feed the same ration all winter and need to plan less labour. Covering is quick and hassle-free, which brings a great sense of calm and saves us a lot of time.
Jos Faassen – Dairy farm Noordzigt
Working faster with fewer people thanks to a lasagna pit
We’ve been using the lasagna pit for ten years now, and the system fits perfectly with the way we farm. One person can handle the covering with ease — no tight planning needed. This keeps the quality consistent and lets us ensile small quantities whenever it suits us.
Pier Jan Noordmans - Organic dairy farm
Easy covering of a wide silo for 500 cows
Covering the silos used to be hard work. Now, it’s effortless — and faster than we expected. The system is robust, easy to operate, and fits perfectly with our large feed storage. It’s truly an investment that pays off every single day.
