High Rye Seeding Rates Prove Effective for Weed Suppression

A new Weed Science Society of America research article shows a generously seeded cereal rye cover crop helps reduce weed pressure for organic no-till soybean production

WESTMINSTER, Colo., July 14, 2026 /PRNewswire/ — A Weed Science Society of America (WSSA) journal, Weed Science, recently published a research article showing that a cereal rye cover crop helps reduce weed pressure for organic no-till soybean production, particularly when seeded at higher rates. The two-year research study reviewed field experiments conducted during the 2021-2022 and 2022-2023 growing seasons near Rock Springs, Pennsylvania, at the Pennsylvania State University Russell E. Larson Agricultural Research Center.

“The aim of this study was to compare the magnitude of weed control and soybean yield under different cereal rye densities within the soybean phase of cover-crop based organic rotational no-till production,” states Laurel Wellman, a Ph.D. student in plant sciences at Pennsylvania State University, and the study’s corresponding author. “Our results indicated that all cereal rye seeding rates reduced weed biomass compared to the unseeded cereal rye control plots, and that the higher cereal rye seeding rates reduced weed biomass significantly more than the lower seeding rates.” 

In two experiments, the researchers evaluated rye cultural management strategies for rye biomass, weed suppression, and soybean yield. They tested: 

four rye seeding rates (0.5-3 bu. acre) and two sowing arrangements (grid vs. row sowing)fall-applied poultry litter (0, 1.5, 3 tons acre) with two soybean planting dates (planting green or standard planting). 

“Increasing cereal rye seeding rate did not lead to increased rye biomass but did increase weed suppression,” points out Wellman. “Soybean yield was unaffected by rye seeding rates, and sowing arrangement did not affect any response.” 

Interestingly, “while fall poultry litter significantly increased rye biomass, weed suppression was unaffected,” she adds.

During one of the two cropping seasons studied, planting green reduced soybean establishment and yield, note the researchers. However, they also state that “these results highlight the limitations of organic no-till soybean production within grain crop rotations in the Northeastern U.S. when using cereal rye as a stand-alone weed suppression method. Increasing cereal rye seeding rates or applying fall fertility could be effective cultural practices when integrated with other weed control tactics to supplement weed suppression by rye surface mulch.” 

Overall, and perhaps most importantly, notes Wellman, the study “indicates that higher cereal rye seeding rates improved weed suppression independently of cereal rye biomass.” 

More information about the study is available online in the article: “Cultural management of cereal rye for weed suppression in cover crop-based organic rotational no-till soybean.” The research article is among others recently featured in Weed Science, a Weed Science Society of America journal, published by Cambridge University Press. Wellman can be contacted about the study at lew5444@psu.edu.

State Grid Changzhou Power Supply Company Commissions the City’s First Whole-Village Photovoltaic Project

Published

on

By

CHANGZHOU, China, Nov. 9, 2026 /PRNewswire/ — On November 5, Changzhou’s first whole-village photovoltaic (PV) project was officially commissioned in Heshu Village, Lijia Town, Wujin District. Rooftops of 40 households and the village’s corridors accommodate a total of 1.08 MW of PV capacity, yet from a distance, almost no trace of the installation can be seen.

This “invisibility” is by design. Heshu Village’s rural houses were delivered under unified planning and construction in November 2022. The village is a pilot for Jiangsu Province’s homestead system reform and a national demonstration village for rural governance. Its neat eaves and ample rooftop area provided favorable conditions for whole-village PV development, while also imposing higher requirements on construction.

For the two housing types of 140 square meters and 90 square meters, the contractor designed customized layouts of 36 and 25 modules respectively, with PV panels laid along the roof slope. In conventional practice, the gap between PV panels and tiles is about 20 centimeters; in Heshu Village, it was reduced to 12 centimeters. Down-conductors are routed neatly along walls, so the rooftops look flat from afar and the layout appears orderly up close, without disrupting the original contours of the houses.

“From a distance, it looks like village scenery; only up close can you tell it is a PV power station,” said Zhang Xiongwei, project contact person at State Grid Changzhou Power Supply Company. He explained that, in line with Heshu Village’s Jiangnan water-town character of white walls and dark tiles, the project follows the original roof contours and uses black, low-reflection PV modules so that the PV equipment blends into the rooftops. Power supporting equipment is painted or decorated with colored drawings to fit the surrounding village landscape and merge into the village’s appearance.

According to estimates, the whole-village PV project generates about 1.18 million kWh of electricity annually, equivalent to the annual electricity consumption of 360 ordinary households, and can reduce carbon dioxide emissions by about 700 tons per year. With green benefits secured, the question is how to divide the economic returns. Heshu Village adopted a model of “government promotion, grid support, state-owned enterprise demonstration, village committee organization, and resident benefits”: the state-owned platform Wujin Digital Energy is responsible for investment, construction, and operation and maintenance, and pays rent to residents and the village committee; the village committee convenes general meetings of property owners to promptly respond to residents’ concerns and organize contract signing; and Changzhou Power Supply Company is responsible for technical guidance and the connection of supporting power facilities.

Residents only need to provide their rooftops and can receive a cumulative rooftop rental income of about 33,000 yuan over 20 years. In addition to a three-year roof waterproofing insurance, State Grid Changzhou Power Supply Company has also introduced Yingda Insurance to provide a seven-year extended warranty service. The village collective receives rent for the PV corridors, as well as incentives that give back to rural development, such as village street lighting, Party-building publicity sites, and convenient service venues. The investor earns returns through power generation, with an investment payback period of about 11 years. The project adopts a connection scheme of “800 V low-voltage collection and 10 kV medium-voltage grid connection,” significantly improving power quality and supply reliability and markedly enhancing the project’s ability to interact with the power grid.

The 2026 No. 1 Central Document proposed “advancing the construction of livable, workable, and beautiful villages in accordance with local conditions,” and the National Energy Administration requires “guiding the scientific layout and orderly development of rural distributed PV according to grid carrying capacity.” Heshu Village’s exploration is precisely the implementation of this guidance at the village level. In the future, Changzhou will also explore promoting the simultaneous design and integrated construction of rural self-renewal housing and PV, so that such village landscapes can take root in more rural areas.

UAE becomes first country outside Europe to implement eATA Carnet system

Published

on

By

DUBAI, UAE, Nov. 9, 2026 /PRNewswire/ — The UAE commenced its rollout of the eATA Carnet system on 9 November 2026, becoming the first country outside Europe to adopt the innovative digital solution. The initiative is being implemented through collaboration between Dubai Chambers, the Federal Authority for Identity, Citizenship, Customs and Port Security (ICP), and Dubai Customs.

The system enables ATA Carnets to be issued and processed electronically, replacing paper-based procedures with digital declarations, QR codes, and transaction records. It is designed to accelerate customs clearance, improve transparency, and facilitate international trade and events.

Dubai Chamber of Commerce, one of the three chambers under the umbrella of Dubai Chambers, has served as the UAE’s National Guaranteeing and Issuing Association for ATA Carnets since 2011. The chamber played a key role in preparing for the implementation, working closely with national customs authorities and the International Chamber of Commerce (ICC) on technical consultations, training, and pre-launch testing.

Dubai Chambers is one of only 13 of the ICC’s 1,200 member chambers worldwide to implement the eATA Carnet system.

ATA Carnets allow eligible goods to enter participating countries temporarily without payment of customs duties or taxes, provided they are subsequently re-exported. Valid for up to one year, they simplify customs requirements for exhibitions, commercial samples, and professional equipment, reducing paperwork and the need for separate customs guarantees.

Between the UAE’s adoption of the ATA Carnet system in 2011 and the end of 2025, 63,591 carnets were issued and received, covering goods worth AED 54.4 billion. In 2025 alone, Dubai Chamber of Commerce issued and received 5,960 carnets covering goods valued at AED 5.6 billion, up 11.2% in number and 30% in value year-on-year.

The UAE’s transition follows the June 2026 rollout across 30 European countries. Full global digitalisation of the ATA Carnet system is expected by 1 January 2028.

FREETOWN, Sierra Leone, Nov. 9, 2026 /PRNewswire/ — Agilix Labs has been awarded a grant to use AI and cloud technology from Amazon Web Services, Inc. (AWS) through the AWS Education Equity Initiative to support the Finder Program in Sierra Leone. The program is run by the Future Learning Institute (FLI), which Agilix Labs established in 2025 under an agreement with the country’s Ministry of Technical and Higher Education. On Nov. 10, FLI formally launches the program and opens its second Community Learning Center at Freetown Polytechnic.

A Finder is a young person the community brings its questions to. The Finder uses AI with local judgment, checks the work and brings back something a trader, a farmer or a teacher can use.

The program is for young Sierra Leoneans who qualified for university but couldn’t get a place, including young women, students with disabilities and young people from rural areas and low-income families.

“Our young people know their communities better than anyone,” said Mustapha Turay, President, FLI Centers in Sierra Leone. “I promised myself that whatever education I got in the United States, I would bring it home. We started in Kono. Now Freetown has a center of its own.”

Over the year-long program, learners take on questions from local businesses and community groups and work with AI to answer them. Lessons run on Agilix Dawn, which keeps working when the signal drops. With the grant, learners’ AI work will run on AWS, through Amazon Bedrock.

“We founded FLI to help young people get jobs, starting with those who were ready to learn and had no place to do it,” said Curt Allen, Co-Founder, Chairman and CEO, Agilix Labs. “At our centers, they use AI to serve their own communities. Finder is the job we’re training them for.”
