One management challenge that is increasingly plaguing many of us as we attempt to “master” the art of direct-seeding or no-till is managing field borders. Many growers have resorted to spraying edges with Roundup. This has resulted in killing native cover grasses.
It’s becoming increasingly difficult to keep China lettuce, cheat grass, Italian rye, bedstraw and a host of other obnoxious weeds from encroaching into the fields. If fences are still on field edges, the problem is magnified.
A leader from the Australia Zero Tillage Association participating in a Direct Seed Association tour several years ago warned us we were heading for a disaster relying too heavily on Roundup. But few seem to come up with alternatives that have long-lasting effectiveness.
Is there a library of management strategies published anywhere in the annals of no-till literature on this topic? Maybe this should be a subject of focus at the next National No-Tillage Conference. How many of you may be seeing a problem with weed control on field edges?
