I cannot find the article but I’ve read recently some young farmer pontificating about the benefit of root crops (potatoes in his case) as part of his armoury against grass weeds. Basically he was renting land out to a potato grower because he believed it helped his war against grass weeds. Now obviously there’s chemistry available to root crops that’s not available to cereals but surely mixing up about 14 inches of soil to get the potato seedbed makes the issue worse by mixing grass weeds through the entire usable soil profile. Or is he right? The combination of ploughing, battering the soil into a very fine tilth and then root crop herbicides works? Also I guess with regards to potatoes they shade out other competition quite quickly as well. Any views?
