It all starts with the soil. The soil in our region is the perfectly suitable heavy clay soil for celeriac (Sluis, the Netherlands). These soils are analysed and selected with great accuracy. We start planting the early celeriac in March and the rest around the end of April and May.
Our celeriac plants, which are raised by a plant breeder, are planted with a full automatic robot transplanter. This transplanter plants 6 rows at one time, which gives us high capacity combined with extreme accuracy. We plant between 70.000 and 90.000 plants per hectare.
After the plants are planted, in most cases, they are irrigated immediately to give them a good start. We try to let them grow gradually and implementing an minimalistic chemical use policy, to obtain as little residue as possible. Every detail counts. For example, our celeriac is continuously monitored by leaf juice extract tests to obtain the correct values up to cell level.
