Some no-tillers are checking less often while relying on Roundup Ready and insect-resistant crops, but experts worry about the emergence of new problems.
Many no-tillers scout their fields less intensely than they did before Roundup Ready and insect resistant crops became popular. And although the decrease in scouting may vary from farm to farm, the consultants and growers contacted by No-Till Farmer caution that the trend could bring big problems.
Many no-tillers are thinking about short-season crops, forage and ground covers, and some of those growers turned to Farmer’s Forum, the online bulletin board at www.no-tillfarmer.com, for advice from folks with experience in similar situations. Here are highlights from their discussions.
The whole world changed for me 18 years ago. Thanks — or no thanks — to big farming and a bad economy, I lost nearly everything I owned — a 4,000-acre operation including land, equipment, 500 beef cows, trucks, cars, personal tools and anything else that the bankers could find in the sheds to auction off.
With fewer new herbicides coming on the market each year, no-tillers are paying much closer attention to developing more effective weed-management plans. As a result, no-tillers are intently studying how various herbicide and tankmix combinations perform in their fields.
During a symposium on glyphosate-resistant weeds held during the annual early winter meeting of the North Central Weed Science Society in St. Louis, Mo., university researchers confirmed the development of glyphosate-resistant waterhemp.
If you're interested in harvesting top yields with Roundup Ready no-till corn and soybeans, it’s likely that you’ll have to add residual herbicides to the weed-control mix.
When marion calmer, a no-tiller from Alpha, Ill., says that he does on-farm research, he really means it. Calmer has conducted research since 1985, working with an average of 380 no-till corn and soybean plots each year.
Some zero-tillers in Manitoba are taking a sober second look at herbicide-tolerant crops and the impact they might have on the economics of their no-till systems.
A recent study by Virginia Polytechnic University educators sheds some light on the true cost of no-till weed control. Besides looking at herbicide costs, the study took a close look at the role that manure application rates have in determining weed-control costs.
