2017 Farm Journal Midwest Crop Tour – Day 4

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Presented by AgXploreOverall Tour Summary and yield averagesSee Day 1 results from the Farm Journal Midwest Crop TourSee Day 2 results from the Farm Journal Midwest Crop TourSee Day 3 results from the Farm Journal Midwest Crop TourFinal results for the entire eastern leg of this year’s Midwest Crop Tour for Iowa and Minnesota.IowaCorn – 179.79 bushels per acre Soybeans – 1092.92 pods in a 3 x 3 foot square MinnesotaCorn – 191.54 bushels per acreSoybeans – 1019.96 pods in a 3 x 3 foot squareI am on another split route today as we head from Iowa City, Iowa to Rochester, Minnesota and I could not have a better driver for Day #4. I have had the chance to get to know Dick Overby over the years here on tour. He is from Minnesota and is retired from Rain & Hail, LLC. His perspective while driving through his part of the country is second to none and I am looking forward to getting started.1:08 p.m.Our final stop of the day and the 2017 Midwest Crop Tour is in Olmsted County, Minnesota. We are having a heck of a run of really nice corn here in the southern part of the state. This field was no exception as our yield guess here was 239. We did find some early hail damage in the soybeans across the road. The beans we have seen so far have not been all that impressive and hail was the last thing they need. Our pod count here in a 3 x 3 square was 1033.Olmsted County, MinnesotaOlmsted County, MinnesotaOlmsted County, Minnesota12:30 p.m.Corn continues to be outstanding in Minnesota. This stop was in Dodge County. Corn plants were very healthy and we have not seen any agronomic issues in this state. The most surprising fact about this sample is that two of our 3 ears were 14 around. This 20 inch row field takes the day so far at 250 bushels to the acre. Soybeans were not the greatest here. These were also in 20 inch rows but pods were sparse here. Our count was 663 in a 3 x 3 foot square.Dodge County, MinnesotaDodge County, MinnesotaDodge County, Minnesota12:10 p.m.11:40 a.m.Into Minnesota and Mower County. I think our crew was mildly disappointed in what we have seen so far today. Just not the numbers Iowa is known for and well below the area we sampled did just a year ago. This corn was in the early dent stage and it is by far the best we have been in today and the best for me all week. This field’s yield is 248.9. Needless to say our Minnesota driver is pretty please. The soybeans were about what we have seen thus far and the pod count was helped by one plant have 106 pods on it. Our 3 x 3 count here is 1122.Mower County, MinnesotaMower County, Minnesota10:58 a.m.Mitchell County, Iowa is our next stop and corn had great ears but not enough of them. A low pop here will have our yield check at 148. Soybeans are decent but what is concerning farmers in this area is that they have a long way to go and may not be ready until mid-October. An early frost will spell trouble for this field. Our 3 x 3 pod count here is 790.Mitchell County, IowaMitchell County, Iowa10:20 a.m.Now into Floyd County and things here are no good. Major population and pollination issues abound in these two fields. Our corn yield was estimated at 125. Beans were in 30 inch rows and the plant and pod numbers were more representative of 15 inch rows here. Our pod count was 828.Floyd County, IowaFloyd County, Iowa10:00 a.m.After almost a two hour drive into northeast Iowa we made it to our first sample site. Some light showers moved through this part of Butler County just about an hour ago. By the looks of things they have been getting the rains needed to make for a very nice crop year. This is one of the highest population corn I have seen on this tour and if it weren’t for those numbers, this yield would have been mediocre. Our yield guess here is 190. Soybeans were very green and thick. Pod counts for our 3 plant samples were high and even. Our 3 x3 pod count for this field was 1584.Butler County, IowaButler County, IowaButler County, IowaButler County, Iowalast_img read more

Conference offers advice on nutrient management

first_imgShare Facebook Twitter Google + LinkedIn Pinterest With so much focus on fertilizer these days, where and when it’s applied, a conference will be held in January to inform people about the many approaches and technological advances that can make it easier.The 2nd annual Precision University Jan. 11 in London, Ohio, will feature presentations about technology that can help farmers apply fertilizer in a way that prevents it from running off the land and ending up in Lake Erie or other waterways.The conference is being hosted by Ohio State University Extension and the Digital Agriculture program team in the College of Food, Agricultural, and Environmental Sciences (CFAES) at The Ohio State University. OSU Extension is the outreach arm of CFAES.Starting in September 2017, those who apply fertilizer on more than 50 acres of land in Ohio have had to become certified every three years by passing a test or taking a course in how to safely apply nutrients to their land. The certification requirement is aimed at keeping phosphorous and nitrogen in the soil and away from bodies of water, potentially contributing to algal blooms in Lake Erie and beyond.“We’re trying to bring attention to a relevant topic,” said Kaylee Port, precision agriculture program manager for CFAES.“We’ll be sharing best management practices and nutrient technologies to help growers become even better stewards of the land and water,” she said.Precision University will feature experts in nutrient management technology from industry and academia.The “precision” in Precision University has to do with precision technology, cutting-edge machinery that ensures work on the farm is done with accuracy. Precision technology includes having sprayer nozzles of the right type and size, providing accurate direction and pressure for applying fertilizer. Another example is applying phosphorus with a strip till machine that incorporates the phosphorus into the ground. A traditional spreader typically places nutrients on top of the soil, where they have less of a chance to be taken in by the roots and stand a higher risk of running off with rainfall and seeping into nearby waterways.Besides preserving water quality, “if you can more precisely place your nutrients, you’ll get the best bang for your buck with the product,” Port said.Speakers at Precision University will include: Robert Mullen, director of agronomy for PotashCorp, a Canada-based fertilizer company; Tony Vyn, professor of agronomy, Purdue University; Jim Schwartz, director of practical farm research and agronomy for Beck’s Hybrids; Jamie Bultemeier, director of corporate sales, A&L Great Lakes Laboratories, an Indiana-based agricultural testing company; Brian Arnall, associate professor, Oklahoma State University; Dave Scheiderer, owner, Integrated Ag, an Ohio-based agricultural-consulting firm, and Glen Arnold, OSU Extension educator and field specialist in manure nutrient management systems.The event will be 9 a.m. to 3:30 p.m. at Beck’s Hybrid’s, 720 U.S. 40, in London. The cost is $50, which includes breakfast and lunch.For more information and to register, visit:go.osu.edu/PrecisionU.last_img read more

Is it Time to Implement IoT in the Warehouse?

first_imgInternet of Things Makes it Easier to Steal You… Follow the Puck Tags:#Industrial IoT#warehouse automation Small Business Cybersecurity Threats and How to… Megan Ray NicholsTechnical Writer & Blogger The Internet of Things is growing, becoming part of nearly every industry in the world. Many people have IoT devices in their homes already — Amazon Echo, smart appliances, and similar devices. One place where IoT is surprisingly lacking is in the logistics and distribution industry. Is it time to implement IoT in the warehouse? What can supervisors and business owners do to implement this technology as part of their daily operations?What Is IoT?First, what is the Internet of Things? If you ask 10 IT professionals, you’ll get 10 different answers, but for the average user, the Internet of Things is a series of machines and equipment that can communicate with one another. They can gather information, receive information, send it out, or both. Your DVR, smart fridge, and Google Home are all IoT devices.These devices are supposed to make your life easier. You can use a smart fridge to let you know when your food is about to spoil, or an Amazon Echo to play music or reorder something from Amazon. In the manufacturing industry, IoT takes these abilities to a whole new level.Industrial IoTIndustrial IoT is making the lives of individuals in the manufacturing industry easier and more efficient than ever before. Pieces of a production chain can communicate with each other, streamlining the manufacturing process. While even IoT-enabled machines need maintenance, each part of the chain can monitor itself and the equipment around it through attached sensors, alerting maintenance staff to problems before they cause the machine to fail.Supervisors and team members can monitor production in real time, through those same sensors, and catch any hiccups or problems with quality control before they make it through to the packing and shipping department.While this sounds ideal for the manufacturing industry, how can IoT help those in logistics and distribution?Types of Warehouse IoTWhat kinds of IoT can we expect to see in warehouses in the future, as supervisors decide to adopt IoT in their facilities?Autonomous picking robots are already starting to make their way into the industry. Amazon purchased robotics startup Kiva Systems in 2012, and since then, has deployed more than 30,000 picking bots in their distribution centers. Statistics show that 55% of your warehouse labor burden comes from picking. Collaborative robots, or cobots, like these will work alongside a human workforce, rather than replacing them to improve picking efficiency.Autonomous vehicles are also making their way into warehouses, in the form of automatic guided vehicles or AGVs. Imagine a pallet jack that doesn’t require an operator. Instead, it can move to a specific location, pick up the pallet automatically and relocate it safely and efficiently, freeing up team members to complete other tasks. The programming of specialized AGVs could allow them to work with a variety of containers of different sizes and shapes to reduce the risk of lifting-related on-the-job injuries.Warehouse management systems, either cloud-based or in-house, can be tied into an IoT system, allowing the computer to keep track of inventory location and movement in real time. From there, a supervisor or team leader can get a sense of the floor’s productivity and efficiency with a few keystrokes instead of spending hours reading reports.Some of the industrial IoT applications could apply for use in warehouses as well. Any piece of machinery in the warehouse, equipped with those same sensors we mentioned a moment ago, could monitor its health and alert maintenance staff if there’s a problem. Attaching RFID sensors to inventory could allow the IoT system to track inventory movements.The possibilities are endless, so why haven’t logistics and distribution companies started adopting these new technologies?Slow AdoptionThere are a few hurdles that might stand in the way of IoT in the logistics and distribution industry. The largest of these is the cost of initial implementation. The equipment, training, and new crew necessary to add these new devices to a warehouse is expensive, to say the least, which might leave it out of reach for smaller logistics companies.There is also the threat of micromanagement. While efficiency is critical in these settings, there’s a fine line between using technology to make the job more efficient and using it to micromanage the entire process.Amazon earned the ire of its consumers when it released plans to make wearable trackers mandatory for its picking teams. The retail giant claimed they would only use these devices to collect information about productivity on the warehouse floor, but it’s a slippery slope. Collecting information could quickly turn into micromanagement, alienating employees and damaging efficiency. Some experts even called these devices an affront to workers’ rights.Finally, there is the problem of system vulnerability. Any networked system is vulnerable to attack, which could put protected customer or client information at risk. Even if you keep your entire network in-house if someone accesses it from their home office, that opens a door for savvy hackers to slip inside. You should address this problem before introducing any new IoT technologies to a warehouse.Benefits of IoT in the WarehouseWhat are some of the potential benefits of implementing IoT in warehouses?The first major benefit is in the form of inventory management. RFID or Bluetooth trackers can keep track of inventory in real time, from the moment it enters the warehouse to the moment it ships out. If something is running low, an IoT system can alert management, or in some cases, even place an order from a supplier on its own.Efficiency is the most significant benefit of IoT in this setting. Mobile computers, connected to the warehouse management system, enable team members to complete their job from anywhere without having to return to a stationary computer, interrupting their workflow.Using IoT in picking and packaging can help reduce mistakes, preventing orders from being shipped to the wrong customer. It can also cut theft-related losses, either in-house or in transit, by keeping a close digital eye on everything that comes in or out of the warehouse. That could be extremely beneficial for companies that work with high-dollar items like electronics or jewelry.IoT can also make it easier to engage with customers. Since you’ve got an eagle-eye view of your inventory, you can integrate this information into your website. If a customer is interested in ordering a phone, for example, they’re more likely to make their purchase if they know there is one in stock, rather than placing the order and receiving a “your product is out of stock and back-ordered until (date)” email after they thought they had finalized their purchase.Adopting IoTHow can managers and business owners start the process and get IoT set up in their facilities?Start by getting everyone on board. This change is going to affect everyone, so you don’t want to start introducing major technology without informing everyone involved.Next, start talking to some IoT experts. You won’t want to attempt this transition without assistance or advanced preparation. There are plenty of experts out there for you to choose from, so find someone who is compatible and aligned with your company’s culture and goals.Make your changes slowly. If you try to do everything at once, and your system hasn’t perfectly synced, it could trigger a cascade failure and take your entire warehouse offline while you scramble to fix it. Implement one piece at a time, and once you’re sure that works, move on to the next part.In the meantime, offer new training for your employees, and hire some IT and IoT experts to keep on staff to maintain the system once it’s in place.Finally, make sure you maintain the system. Once you’ve had it installed, you can’t merely sit back and enjoy the fruits of your labor. Here is where your IT team comes in. The IoT devices may need some little tweaks or adjustments to make sure they’re operating at optimum levels.Embracing Innovation Will Move the Industry ForwardWarehouses and the logistics industry as a whole have been slow to adopt the Internet of Things, but a change is coming. While these machines won’t ever entirely replace a human workforce, as more commerce becomes digital, these companies will need to adapt to keep up or get left behind as the world changes without them.

Black Church Leadership Makes Call to Action at MLK Prayer Breakfast

Black Church Leadership Makes Call to Action at MLK Prayer Breakfast

first_imgThe District’s Shiloh Baptist Church hosted its 27th Annual Martin Luther King Memorial Prayer Breakfast. The Rev. William Barber II, president of the North Carolina chapter of the NAACP, used the event to call for a new Poor People’s Campaign.In the wake of King’s death in 1968, the Rev. Ralph Abernathy made good on Dr. King’s call for a “Poor People’s Campaign,” bringing about 3,000 people to DC who set up makeshift campsites in the shadows of the Washington Monument.The Rev. William Barber, president of the North Carolina chapter of the NAACP, issued a call for a new Poor People’s campaign during the King Memorial Prayer Breakfast. (Photo by Hamil R. Harris)“We are doing a multi-year campaign to engage more than 100 million people who sometimes never even hear their name or their condition,” Barber said. “We are dealing with the systemic racism, systemic poverty, ecological devastation, the war economy, and the distorted moral narrative that is promoted by Christian nationalism that is contrary to our deepest Christian values.”During his speech Barber reminded those gathered of how Martin Luther King was very unpopular after he spoke out against the Vietnam War on April 4th, 1967 at the Riverside Church in New York City. “He was killed one year to date after that sermon,” Barber said. “[FBI Director] J Edgar Hoover labeled him as the number one enemy of America and there were others in Black leadership who challenged him.”Shiloh Baptist Church Pastor, the Rev. Doctor Wallace Charles Smith, welcomed Barber to a breakfast that took place on the Saturday morning after the federal government was shut down. The fellowship hall was packed with federal workers, former White House appointees, and veterans of the Civil Rights battles that many thought were won in the 1960s.“This demonstrates that the church is fighting on and we will not give up,” Smith said. “Even though the government is shut down, the church is still open . . .”The Rev. Thomas L. Bowen, minister of Congregational Life at Shiloh and director of Religious Affairs for Mayor Muriel Bowser said,” There has never been a time like this and the stakes are raised.”“We are picking up where Dr. King left off. The dream has to be one that uplifts everyone and we have much more work to do,” said Bowen.Barber, co-chair of the Poor People’s Campaign, said during Black History month he will lead a national effort where people will protest in various sites across the country in groups of 2,500. “Fifty years after the Poor People’s Campaign, it is about motor mobilization. It is a launch, we are not commemorating the Poor People’s Campaign, we are reigniting it.”“We need to remember that the real Martin Luther King found himself having to take on a society that had a neurotic sickness and a septic commitment to racism, poverty, and war that was literally destroying the soul of this nation and ripping apart its moral promises,” Barber said. “When Dr. King rendered this diagnosis and committed to raise a Poor People’s Campaign for a moral revolution of values with those who had nothing to lose, he was declared even more an enemy of the state and a threat to the powers that be.”In the same way King became disliked, Barber said, ministers today must be willing to become unpopular if social change is going to come.last_img read more

Scientists consider the possibility of adding aerosols or modifying clouds to slow

Scientists consider the possibility of adding aerosols or modifying clouds to slow

first_img Governments send representatives to climate meetings hoping to establish a consensus regarding carbon emission reductions, and the citizens of the world debate the source or even reality of global warming and what ought to be done about it. Yet the planet continues to warm. Scientists around the globe are convinced that unless something is done soon, the planet could become a miserable place, or worse, we could cause our own extinction. While some progress has been made in limiting carbon emissions, most would agree such efforts are falling short. For that reason, some scientists have begun looking at other ways to prevent catastrophe. Two of the most debated are aerosol injection and cloud seeding.The idea behind injecting aerosols into the atmosphere, as Niemeier and Tilmes point out, is to mimic the cooling that occurs when volcanoes erupt. Along with smoke, volcanoes also emit a lot of sulfur, which is why scientists suggest we do the same artificially. But that might be easier said than done, Niemeier and Tilmes note, because it would involve replicating an eruption the size of Mount Pinatubo every day for approximately the next century and a half.And there are problems with cloud seeding, too, which might be done to disperse cirrus clouds, preventing them from trapping heat—the main problem is lack of precision; doing it wrong could lead to more warming, for example.For these reasons and many more, Pasztor, Scharf and Schmidt suggest taking a very serious look at how to prevent one country, group or even a wealthy individual from striking out on their own with such approaches. Adding a governing body to the equation, they suggest, could prevent these scenarios. More information: Ulrike Lohmann et al. A cirrus cloud climate dial?, Science (2017).

How to govern geoengineering?, Science (2017). DOI: 10.1126/science.aan6794 (Phys.org)—Scientists looking at alternative approaches to staving off global warming have published two Perspective pieces in the journal Science. In the first, Ulrike Niemeier and Simone Tilmes with the Max Planck Institute and the National Center for Atmospheric Research in the U.S., respectively, address the possibility of injecting aerosols into the atmosphere as a means to limit heat passing through. In the second, Niemeier has paired up with Blaž Gasparini with the Institute of Atmospheric and Climate Science in Switzerland to look at the issues involved with attempting to disperse clouds that prevent heat in the atmosphere from escaping back into space. In an editorial in the same journal issue, Janos Pasztor, Cynthia Scharf and Kai-Uwe Schmidt consider how we might govern geoengineering attempts to prevent a reckless few from possibly destroying the planet they are trying to save.
