What are the pros and cons of different Reduced Cultivationing drills? Which one is best for me?
Tine cultivator drill: Good on cost and flexibility Does not leave slots Less wear Potentially very accurate depth of drilling control Can handle higher volumes of surface trash. Disc cultivator drill: Minimal soil disturbance and therefore opportunity for further weed germination Most expensive Does not cope as well in wet, can leave slits which favours slugs and can push straw into the slit which leads to poor soil seed contact and hence emergence. Disc direct drill: Traditional direct drill. Cheaper that disc cultivator drill and as good with similar issues. However, no soil movement or consolidation at all so can leave straw in slit giving very anaerobic conditions if wet which kills crops. Can also lead to greater compaction. Normal coulter drill: Unsuitable in presence of a lot of straw or clods. Disc coulters better way into a reduced cultivation system.
