Flick through some recent issues of profi and you will spot several tine cultivators designed to work ultra-shallow. The Koralin is of the same ilk but mixes discs with fewer tines to move just 2-3cm of dirt. We tested one of the early units across 1,000ha
The probability of a glyphosate ban in many countries, along with current fuel prices, will have many farmers questioning their crop establishment approach. The former is the main reason why there is a plethora of ultra-shallow cultivators hitting the market, with the Lemken solution being the Koralin, which uses its full working width to encourage weed seeds to germinate and uproot any growing plants.
Unlike several other machines that rely on a myriad of tines, the chaps from Alpen have opted for two rows of discs followed by wide point
tines. A special feature of the Koralin is its depth control system. The topsoil cultivator utilises five support wheels as well as the pair of transport wheels, and these don’t leave a trace in the field. Our 6.60m wide test machine is the smaller of the two models currently in the Koralin range; the other is 8.40m. A 12.40m model is on the cards, with pre-production machines undergoing testing. In the wet summer of 2021, we used the Koralin 9/660 to work mainly cereal and oilseed rape stubbles.
