Hi Phill There was more to the story than I told the first time. We do all our NPK before planting, and weed control at planting because we don't have the option of going back. The catch? We're laying transparent plastic over the corn as it's planted. I don't know if you got down to AgriFest in Canning this year, but our planter was on display down there, along with a small demo that AgriPoint had done with the machine. The planter was developed and marketed by Samco. Basically, once that plastic is down, we walk away, and we don't come back until we roll in with the chopper. This system is catching about 300 CHU for us, building more starch, and more tonnage. Only downside is the cost. This year the plastic ran 175/ac. Next year we're hoping to see it under 150, and probably 120. However, even at 175, it should pay. The jury is still out on that.... We'll probably look at some other weed control options next year too, but it's still going to be pre-emerge. There's just no way to go back in as the corn basically springs up to near waist high once it breaks the plastic, and the plastic will continue to linger for a good part of the summer. Anyhow, for anyone that's interested, check out the link... Rod
