Sub-Surface Drip Irrigation a Possible Solution for some Georgia Peanut Farmers

Sub-surface drip irrigation gets implemented in a field at Stripling Irrigation Research Park in Camilla, Georgia. Image credit: Wes Porter/UGA.Drip irrigation systems have long helped Georgia vegetable farmers grow high yielding crops. Sub-surface drip irrigation can help some Georgia peanut farmers water their crops more efficiently, according to a University of Georgia Cooperative Extension expert. And, it won't interfere with peanut digging equipment.

While not suitable for all peanut fields, sub-surface drip irrigation could be used in smaller fields with irregular shapes where pivots are unable to reach or in plots with dry corners. Read more

Australian Seed Destructor Could be Answer for Midwest Farmers

It’s a piece of equipment that probably isn’t on many Midwest farmers’ radars at this time, but could eventually be a new tool against the growing herbicide-resistant weed problem, said a University of Illinois crop scientist.

With the effectiveness of many herbicide options being compromised due to the evolution of weed resistance and no new products on the immediate horizon, Aaron Hager said now is the time to look at non-chemical tactics that can be integrated into a management system. Read more

Cornfield’s ‘Cool’ Block O Designed to Spur Conversations on Precision Ag Potential

This cornfield bordering I-70 at The Ohio State University’s Molly Caren Agricultural Center in London, Ohio, was planted with two hybrids of different maturity dates and tassel colors. Taken July 23, the image shows the Block O hybrid has not yet tasseled, causing it to appear deeper green than the other hybrid. The project demonstrates technology newly available this year allowing the planting of two different hybrids in the same field to maximize yields.

Ag's Next Frontier? Growing Plants in Space.

Space may not be the final frontier for Anna-Lisa Paul and Robert Ferl; they want to grow plants there. Because, who knows, we may one day try to live on Mars, and to survive, we’ll have to grow our own food.

Thus far, experiments by the two pioneering scientists have proven so successful that, earlier this month, NASA recognized their research with one of its three awards in the category of the Most Compelling Results. Paul and Ferl have been conducting plants-in-space research for 20 years. Read more

Adapt-N Changes When We Apply Nitrogen

Nitrogen management in corn is an important consideration for corn producers. With the rising costs of inputs and concerns of the overuse of fertilizers, now more than ever it is vital that growers maximize their bushels per acre with the least amount of inputs as possible.

Plant Breeder Boosts Soybean Diversity, Develops Soybean Rust-Resistant Plant

Research geneticist Ram Singh crossed soybean with a related wild, perennial plant from Australia, introducing new genetic diversity to the soybean plant. Photo by L. Brian Stauffer.It took decades of painstaking work, but research geneticist Ram Singh managed to cross a popular soybean variety (“Dwight” Glycine max) with a related wild perennial plant that grows like a weed in Australia, producing the first fertile soybean plants that are resistant to soybean rust, soybean cyst nematode and other pathogens of soy.

Irrigation Pressure Regulation

Our team has traveled all over the USA and across the globe, and noticed two strange things when it comes to pressure regulation: some growers will tell you that it’s the best way to save water and energy, while others will claim it’s nothing but a waste of time and money unless you have sloped fields.

Automatic Section Control Technology - Precision Row Crop Planting

Automatic section control (ASC) technology for planters has gained interest among growers because of its potential savings and other benefits. Automatic section control is also referred to as auto-swath or row clutches when talking about planters. As the name suggests, this technology improves planting efficiency by automatically turning OFF planter sections or individual rows in areas that have been previously planted (e.g., headlands or point rows) or areas designated as no-plant zones (e.g., grassed waterways, terraces, outside a field boundary).

Precision Ag Company Launches New Web, Mobile App To Control Pests, Disease & Improve Soil Nutrients

Spensa Technologies Inc., a precision agriculture company in Purdue Research Park, has launched a new Web and mobile enabled application to help growers and consultants more efficiently scout insects, weeds and disease, identify agronomic issues and nutrient deficiencies. 

The new application, called "OpenScout," helps field and crop advisers to more easily identify and document the locations of insects, weeds, disease, nutrient deficiencies and general agronomic issues and assign a severity in a more precise manner so growers can strategically mitigate problems before they spread.

Robotic Orchard Bins To Be Tested By WSU Scientists

The manually operated research prototype of a self-propelled bin carrier created by WSU researchers.Washington State University researchers were awarded a $1 million federal grant to develop an intelligent bin management system supported by a robotic self-propelled fruit bin carrier in tree fruit orchards.

“This grant gives us the chance to convert what we thought would work into something that orchards can use,” said Dr. Qin Zhang, who will lead the research. “It’s one aspect to help address the overall labor shortage that orchards are dealing with.” Read more
