De-inking paper sludge amendment affects weeds in the presence or absence of herbicide in a soybean-corn rotation
The application of de-inking paper sludge (DPS), a C-rich but N-poor soil amendment, can sometimes decrease plant growth. This property needs to be investigated to develop the knowledge and management methods necessary for potential weed control. Today, there is no information on the effectiveness of using DPS to control weeds within a soybean [Glycine max (L.) Merr.]-corn (Zea mays L.) rotation. ...

Long-term agronomic performance of organic and conventional field crops in the mid-atlantic region
Despite increasing interest in organic grain crop production, there is inadequate information regarding the performance of organically-produced grain crops in the United States, especially in Coastal Plain soils of the mid-Atlantic region. We report on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yields at the USDA-ARS Beltsville Farming Systems Project ...

Making Better Herbicide Decisions with Weed Density Mapping
Proper weed control early during the growing season is essential for reducing nutrient competition, gaining optimal crop health, and preventing yield loss. Weed management in corn and soybeans can be an extremely difficult problem to tackle and, if left unmanaged, can cause nearly a 52% corn yield loss and 49% yield loss in soybeans according to research conducted by the Weed Science Society of ...

Organic and conventional production systems in the wisconsin integrated cropping systems trials: i. Productivity 1990–2002
During the last half-century, agriculture in the upper U.S. Midwest has changed from limited-input, integrated grain–livestock systems to primarily high-input specialized livestock or grain systems. This trend has spawned a debate regarding which cropping systems are more sustainable and led to the question: can diverse, low-input cropping systems (organic systems) be as productive as ...

Reduced soil tilling helps both soils and yields
Agriculture degrades over 24 million acres of fertile soil every year, raising concerns about meeting the rising global demand for food. But a simple farming practice born from the 1930's Dust Bowl could provide a solution, according to new Stanford research. The study, published Dec. 6 in Environmental Research Letters, shows that Midwest farmers who reduced how much they overturned the soil -- ...

ASA Survey Shows Herbicide Strategy Compliance Difficult for Farmers
The Environmental Protection Agency has proposed several pesticide registration plans that could significantly affect farmers’ abilities to utilize herbicides. EPA is responsible for approving registrations on pesticides in the United States and has consistently been found by courts to have not properly evaluated the registrations’ effects on endangered species. In order to meet ...

Why consider pre-emergent herbicide?
Resistant weeds, dicamba training, new EPA rules and regulations, and ag companies being bought or merging together have been a few of the topics found in many ag media and publications this winter. In summary, things are continually changing in agriculture and will continue to change. One of those changes that many, if not all growers, have experienced is how to deal with weed resistance. ...

Look to Ag leader to help you comply with new Dicamba rules and regulations
Sometimes, rules and regulations come along to change how you manage your farm. The federal government’s recent action on the common herbicide ingredient dicamba is one such example, and resilient farmers may need to make some changes to comply with new regulations laid out by the U.S. Environmental Protection Agency (EPA) in October 2017. That’s when EPA ruled that three crop ...

Controlling Barnyardgrass with Corn Hybrid Selection
Barnyardgrass is a summer annual grass weed with a global impact on corn production. Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

Fall Tillage Practices And Cover Crops
In my area of Iowa, primarily in Mitchell County, the adoption of strip-till has been huge. There were three or four people that started in the early 2000s, along with my dad, that were pretty vocal about what they were seeing and what kind of benefits they were getting from reducing tillage and going to a strip-till pass. I would love everybody to switch to strip-till and then to no-till down ...

2020 Planting Prep: How Hydraulic Downforce Can Help
What conditions will you face during spring planting? With 2019’s extreme weather patterns, what comes next is anyone’s guess. That’s why it’s smart to prepare now. Planting into wet soil is completely different from planting into dry, compacted soil. Yet the fundamental challenge is the same—putting seeds in the right place, at the right time, and at the right ...

The developing world is awash in pesticides. Does it have to be?
Herbicides, insecticides and fungicides threaten the environment and human health in many parts of the world. But research is pointing to a better approach. In today’s globalized world, it is not inconceivable that one might drink coffee from Colombia in the morning, munch cashews from Vietnam for lunch and gobble grains from Ethiopia for dinner. That we can enjoy these products is thanks, ...

Family farms can be competitive by focusing on conservation and stewardship
While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...
