Dairy farmers Thom and Meinte Miedema have optimized their feed storage in combination with a covering system. Via Bosch Beton, they got a tailor-made solution with a gutter silo made of new LA retaining walls with an extra long heel. The Agridek covering system runs over the long heel without the need for additional coating. This saves extra costs for earthwork and paving.
Thom Miedema and his cousin Meinte have a dairy farm with 115 dairy cows and around sixty young cattle in Blessum, Friesland. The dairy farmers make the silage in-house, in the form of a lasagna pit and until recently on a concrete slab. For Miedema, this meant that the pit had to be opened and closed up to twelve times a season.
In addition, the Frisian dairy farmers had to deal with a lack of stocks of forage in the winter. The wish was to optimize the storage and provide it with a covering system.
Perfect lasagna pit
“Together with the dairy farmers, Bosch Beton went in search of a silo that was tailored to the company’s needs,” says Douwe Bijlsma, sales representative for the Netherlands at Bosch Beton. “The starting point was that Miedema can better store its high-quality forage. In the new silo, in combination with the Agridek feed concept, the first to last cut is ensiled horizontally, which creates a perfect lasagna silage.’
By combining the energy from the first cut, the structure of the summer cuts and the protein in the last cuts, the farmer saves on by-products, explains Bijlsma. “During the feeding period, the feed is cut vertically. Miedema can offer the cows a complete and constant ration every day.’
Bosch Beton used the new LA300H retaining walls for the new feed store. Thanks to the extra long heel, these walls are particularly suitable for silos with a cover system, says Bijlsma. “We are increasingly seeing a combination of chute silo walls with a permanent covering system. The system runs over the stable heel along the silo walls during covering and silage. Further curing is therefore no longer necessary. It saves extra costs for earthworks and paving.’
The size of the silo is 50x12x3 meters, the warehouse is made of asphalt. To make it complete, Bosch Beton also installed the Bosch Beton duo gutters. These are innovative gutters of our own design, in accordance with the Danish Water Board’s decree, says Bijlsma. ‘The gutter has two drainage pipes: one for clean water and one for pressed juice. The concrete housing protects the drain pipes. As a result, the gutter can be driven over by heavy vehicles without the pipe breaking or being damaged.’

Other advantages are that the gutters can be placed on clean water or dirty water/press juice due to the removable colored lids depending on the situation. With matching start or end flashes, a one-off connection can be made to the press juice pit/fertilizer cellar or, with clean water, to the ditch. In addition, the user can change the drain at any time by simply changing the lid.
Thom and Meinte Miedema chose an Agridek cover system with an Agridek Permanent cover, a galvanized Agridek portal system type 1 with control platform and a complete water management system for the silo. The robust portal system runs around the walls, says Jan Sake Bosch, general manager and sales advisor at Gridek.
‘Thus, the system can easily be driven outside the silo and driven completely through the silo under silage. The combination with the Bosch Beton walls with a longer heel provides the right stability and space to drive over them. It works perfectly. The customer saves on foundation work, and the machine has a stable surface,’ explains the Agridek director.
Great ease of working
Covering the silage can be achieved by one person in half an hour with the covering system. ‘It makes work enormously easy and makes it easier for the milk producer to ensilage twelve times a year,’ says Jan Sake Bosch.
‘The livestock farmer pulls the tarpaulin with integrated water hoses over the silage with an unrolling machine’, continues the Agridek director. “The hoses are then filled with spring or ditch water and in winter with brine. The hoses are automatically filled and kept under pressure by a sensor. When you need to feed, roll up the blanket a little at a time with the machine. The water in the hoses automatically returns to the storage tank.’
According to Jan Sake Bosch, the fantastic thing about this project is that Miedema, Bosch Beton and Agridek have jointly considered the roughage ration. ‘Everything is based on getting the maximum value out of forage. In this system, the twelve layers of silage can be easily ensiled, so that the silage becomes much harder than a traditional silage. The roughage is palatable, which means that the cow’s dry matter intake is high. The farmer thus saves on his feed costs and can thus earn back the system.’
