[QUOTE="Richard III, post: 1751784, member: 933"] I pretty much agree with Silliam, a drills job is to get a seed into the ground in such a way that it will germinate and not be hollowed by a slug. There are however a couple of ways a drill can influence yield a little after that, sometimes a degree of soil mineralisation through soil movement can benefit establishment and conversely sometimes lack of soil movement can aid weed control. When looking at drill trials there are often confounding factors that get in the way of judging which is the best drill. Sam Moore likes to point out that his old Moore drill produced better results than a 750a in a trial in Germany, this was apparently due to his drill mineralising more N than the 750a. Another issue is that the optimum plant stand for a field is impossible to know at drilling time, sometimes thinner crops can yield better than thicker and vice versa. If the chosen drilling rate turns out to be above the optimum for the year, a drill with a poorer establishment rate can give a higher yield, but is it a better drill? Trials are great to see how different drills cope in different soils and conditions, but after measuring the resulting plant stands, I'm not sure it is worth monitoring much further. [/QUOTE]
