I rest my case... you should really stop trying to argue your point, you were wrong yesterday and you're wrong today... its not going to change the fact that your argument is based on flawed education. you should proceed to argue for the case of not littering inorganic material because you'd find that most of us here are in agreement with that. and yes, vineyards do not want any litter on their place because they control the Ph as well as other factors in the soil, and they generally only grow one variety of grape in order to get their perfect wine, they don't want other grape seeds contaminating their crop
