Pöttinger has unveiled SYNKRO stubble cultivators and TERRADISC compact disc harrows for modern stubble cultivation
Farmers are recommended to carry out stubble cultivation right after the harvest. This saves precious water, which is necessary for weeds and volunteer seeds to germinate. Shallow incorporation of the volunteer seeds (cereals, oilseed rape and weeds) into the upper soil layer (approximately five cm) with combined consolidation creates ideal conditions for rapid germination.
Water losses can reach 10 to 15 litres per sq m. By incorporating straw into the top layer of soil, the straw starts to degrade. In addition, the soil surface is protected against further drying out. Mechanical weed control is also regaining importance. Multiple cultivation passes create several waves of germination so weeds can be controlled mechanically - a sustainable solution.
TERRADISC compact disc harrows are low draft and ensure reliable cutting through of harvest residues without clogging. The ideal working depth starts at three to four cm and can be adjusted according to the volume of straw. Even on hard and dry soils, the TERRADISC can be used without any problems. Thanks to their solid construction and the aggressively set concave discs, Pöttinger compact disc harrows enter the soil perfectly.
The two or three row SYNKRO stubble cultivators are an alternative to the compact disc harrow. SYNKRO stubble cultivators are designed for a superior mixing effect, regardless of whether you prefer very shallow or deeper cultivation.
For stubble cultivation, Pöttinger recommends the knife ring or CONOROLL rear rollers, which optimally consolidate the mixture of soil and straw. Thanks to the standardized mountings, other rollers - rotopack, cage roller, double bar cage roller or pack ring roller - can be added quickly and easily to the SYNKRO or TERRADISC.
With the TEGOSEM catch crop sowing unit you can combine soil cultivation and sowing a catch crop in a single pass. That is how you can save time and costs. The TEGOSEM can be combined with PÖTTINGER TERRADISC disc harrows as well as with SYNKRO stubble cultivators.
