no-till update

running about took me past the no-till bean field ( and the first photo tells me my call is correct...and you can see one of [ beans are dicot ]the cotyledons turning yellow as it shrinks )...the corn cobs on the ground are slowly decomposing...according to figures from iowa state university there is bout 6.96 pounds of nitrogen per ton of corn cobs...along with mall amounts of other nutrients....so the cobs are doing something to feed the beans...the weeds aren't and there are quite a few of them mixed in with the beans...there were a lot in the corn crop last season as well ( although i still dispute farmers classification of lamb's quarters as "weeds" ) i have to think this is a function of the fields location...it is with in the city limits of a municipality ( we are on the rural suburban nexus here ) and is probably subject to municipal ordinances concerning chemical applications ( although this does not seem to impede chemlawn, tru-green, or the odd weekend warrior with a spreader from dousing lawns with copious amounts of nitrates and herbicides...what would the difference be ? )...whatever the issue this is still a no-till field as you can see by the rows of beans between the upright corn stalks...i did not find any volunteer corn today...there won't be many but they will be easy to find in another month or so...haven't found the farmer to talk about the reasoning behind the no-till choice yet either...no word from the soybean alliance...their continued silence is a clear indication of a dead end in that search...more thought required.
