[QUOTE="Warnesworth, post: 6873211, member: 3357"] I'll chip in if I may... Slot closure - this is always tricky at best with a disc drill which is why Steve & I at Soil First Farming always harp on, to the point of boredom, about tine drills being a better option early on in your voyage into CA. What do we need to close the slot - tilth. What do we not have in the early years of zero till - tilth. Which is more likely to create a little tilth, a disc or tine? Now [USER=44728]@Two Tone[/USER] 's trial field, one side of the field was too wet, the other too dry, almost. Again both instances where a disc drill is most likely to fall down. We find that tines have a much wider window of drilling opportunity. Rolling will help in good conditions but is never perfect if the soil conditions were not good at the point of drilling. Once you are a few years into a CA system and the top few inches of soil are increasing in SOM and becoming more friable this problem starts to reduce. This field was ploughed last autumn so never a great starting point and this showed with the depth the wheels were sinking on the wetter areas. Mg: yes there could be a soil mag issue here (I have some soil analysis from the neighbouring field so will check that) and mag will certainly show in extremes of wet (sticky) and dry (soil contraction/cracking/slot opening).
