[QUOTE="Philip Hedeng, post: 3730694, member: 40228"] Hi again. From what I see in my no-till OSR field now, rape is not perhaps a lazy rooter, but it's vulnerable to compaction. It grew slowly in the autumn even as it was record warm. On clay it was attacked by slugs for quite a while and took some plants with them. Overall the establishment was poor there but I can't blame just the slugs, there was something else that seemed to lower germination on that soil. When winter arrived it was still fair for the most part. Then as winter ended and spring growth kicked in we saw an awful lot of plants dead. Some small and with thin stems but also large plants, all right next to living plants. Some had poor root systems with roots only along the slot, but there were others with a tap root as well. Some have regrown but a lot are dead. 40 seeds/sq meter drilled (will have to go higher if I do it again). 230 kg NPKS 17-5-10-5 +Mg+B in the slot with seed (will perhaps try MAP in the slot next time. AS mixed in sprayer with night application against slugs and compliment for more N is also considered.) 4 kg Sluxx HP released right behind the slot A lot more Sluxx after emergence This field was not ready for this establishment method, at least with this drill that probably smeared the slot a bit because we used a lot of pressure through that 30-40 % clay and even if it was moist at drilling the weather turned a lot drier afterwards with soil becoming hard to penetrate. My theory now is that a lot of the plants tried to penetrate compacted layers or generally tight soil and that energy forced the plants upwards instead, exposing the growing tip to cold weather. The energy required for penetrating the soil also made it slower to grow above ground I guess. There's a vast difference to the crop depending on which part of the field I look at. Where soil is lighter the crops is at least OK to look at now, but on clay... I just have to see it through. Or close my eyes. Drill is a double disc box drill with gauge wheel at the side and a rubber closing wheel after. Companion crops is another hot topic; sacrificing something else than the cash crop to penetrate through the soil. Berseem clover is the best candidate? Going in after grass ley this year. [/QUOTE]
