Importance of sulfur on soybean production

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Kayla Hawthorne, OCJ field reporterSulfur is essential for soybean production, and more evidence is showing that some farmers in the Midwest may be experiencing a sulfur deficiency that is showing up in some fields.According to Mike Hannewald, Beck’s Hybrids precision farming field advisor, prior to the 1990 Clean Air Act Amendments, crops and soil received enough sulfur through rainfall. That may be changing.“Research is showing that we used to get 20 pounds [of sulfur] per acre free through rain falling. And now in the last few years, we’re getting less than five pounds per acre of sulfur,” Hannewald said.The Environmental Protection Agency established the Acid Rain Program under Title IV of the 1990 Clean Air Act Amendments to reduce the emission of sulfur dioxide and nitrogen oxide into the air. According to the EPA, these compounds rise into the atmosphere and mix with other chemicals, including water and oxygen, and form acidic pollutants, which caused acid rain. The rainfall brought sulfur to the soil, which was an unintended benefit for agriculture.Hannewald said cleaning up the air and environment “adds a unique management challenge that we need to work with in agriculture to be able to ensure that we can produce maximum yields.”Farmers now have to determine if their soybean crops need sulfur. According to Hannewald, sulfur is an important nutrient at every stage of soybean production. He said sulfur helps protect seedlings in cool, wet conditions when they are first planted. Later in the season, sulfur assists with nitrogen uptake and efficiency to keep soybean nodules working at their full potential. Sulfur is also critical for ensuring the protein content is maximized. Ultimately, sulfur is needed throughout soybean production to maximize yield.Hannewald explained there are many forms of sulfur that farmers can use to ensure they maximize their soybean yield. The most popular form of sulfur used is probably ammonium sulfate, but farmers can also use elemental sulfur and foliar feeding for their soybeans.“Just some things to keep in mind [are] that you’re getting enough, making sure it’s available when you need it, and getting that timing right so that second half of the growing season, from flowering on, the soybeans have all the sulfur they need,” Hannawald said.last_img read more

Commissioning ERVs

first_imgWe intended to follow the commissioning process described in a Canadian ventilation standard: CSA-F326, “Residential Mechanical Ventilation Systems.”In Canada, ventilation systems can be designed to meet the building code or as an alternative to comply with CSA-F326 (the case for this meticulously designed mechanical system).CSA-F326 requires the installer to certify that the ventilation system installation complies with the standard by filling out “Form A,” which in turn can be considered by building officials as a performance certificate. Our first job was to figure out the Total Ventilation Capacity (TVC), and then to balance the room-by-room air flows. The standard is very forgiving in that it allows for ±15% on the TCV measurement and ±25% on room-by-room air flow rates when compared to design values (1).Few designers or installers of residential ventilation systems plan for commissioning. Typically the HRV or ERV is tucked high into a corner of the basement mechanical room, with flex-duct contorted and crammed on all four stations.Image credit: AHRIThe Air-Conditioning, Heating, and Refrigeration Institute (AHRI) labels the HRV port for entering outdoor air as Station 1; the port conveying fresh supply air to the house is referred to as Station 2; the port bringing stale air to the HRV or ERV is referred to as Station 3; and the port that conveys stale air destined to be exhausted to the exterior is referred to as Station 4.The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) suggests that the best place for flow collar placement is on the warm side (at Stations 2 and 3), before any branches. When it comes to accurate measurements of air flow, doing a transverse with a Pitot tube comes in third. The second-best approach is to use the more convenient insert-type linear flow measuring station. Of course, the best method is to install a four-quadrant flow measuring station, despite the labor involved.The house in question didn’t have ideal places to install our four-quadrant flow sensors. Having recently invested in a pressure-compensated balometer which I hoped would earn its keep, I decided to measure at Stations 1 and 4. RELATED ARTICLES Residential CommissioningCommissioning Our Heat-Recovery Ventilator Cutting the Gordion Knot of HVAC System Commissioning Designing a Good Ventilation System BY GREG LABBE Air Leaks in Homes Insulated With Spray FoamOrigami-Inspired HomesPastiche ArchitectureNew LED Lights on the Scene What’s going on?Because of constrained access to Stations 2 and 3, the flow collars wouldn’t have made sense, so we had to use a Pitot tube, and the numbers were not reliable. So we took apart the ductwork to check whether the inline dampers were OK. There were no adjustable air flow dampers for this ERV.Then we dove into the manufacturer’s manual to change jumpers on the mother board to offset one of the two fan motors. Still the flow rates were impossible. We were getting in some cases over 100 cfm more exhaust air (at Station 4) than outdoor air (at Station 1), and no HRAI ventilation course could have prepared us for what we went through.The technical literature suggested that it was common for an ERV with a heat transfer wheel to mix in extra “purge” air to combat cross contamination — which might explain our difficulties. In this case, the heat transfer wheel was cut into pie-shaped pieces that fit in walled slots that aim to reduce the cross contamination. It should be noted this particular brand of ERV is quite common in high-performance homes in Ontario, and those who have them love them. We’ve had a previous experience commissioning the same model without such a large spread. Deriving the Total Ventilation CapacityIn the end, we derived TVC by adjusting flows room by room, and then simply ensuring the house pressure was neutral at TVC (see Image #7, below.) Having witnessed the build at the bare duct stage, we knew duct leakage wasn’t an issue, though we could have tested for it.The lessons learned included:Ensure that the mechanical designer selects an HVI-certified or AHRI-certified model; andEnsure that the heat exchanger core uses an airtight membrane that prevents cross-contamination. Greg Labbé is co-owner of BlueGreen Consulting Group, a high-performance home consulting firm that works with architects, builders, and homeowners to optimize the energy performance of new and existing homes through detailed energy modeling and site testing. Following a standard for commissioning the systemFortunately, none of the appliances in the home were susceptible to combustion spillage: there were no CO2 sources (wood or fossil fuel appliances) and there were no exhaust-only appliances that depressurized the house (i.e., no bath exhaust fans and no range hood exhaust fan; the clothes dryer was condensing).center_img A defective control boardIn the end, common sense prevailed. Using a watt meter, we diagnosed that something was the matter with the control board. The board was replaced and in the end, flows in and out were within CSA’s spec for the TVC.By design, this meant that air flow at Station 1 wouldn’t equal air flow at Station 4. The ratio between those two air flows is called the Outdoor Air Correction Factor (OACF), which ideally should stay as close to 1.0 as possible.There’s another cross-contamination measurement called the Exhaust Air Transfer Ratio (EATR), which is the ratio of the exhaust air transfer to the supply flow rate. The ERV in question was laboratory tested in general accordance with CAN/CSA-C439-00, “Standard Methods of Test for Rating the Performance of Heat Recovery Ventilators.”The ERV wasn’t listed as HVI-certified (or AHRI-certified if a commercial unit). The OAFC wasn’t available, but the EATR was calculated at 0.09 by the manufacturer, which translates to about 3% of the exhaust air being transferred into the fresh air stream. In other words, if we wanted 100 cfm of fresh air delivered, we’d have to bump it up to 103 cfm; but that wasn’t consistent with our measured findings in the field. This might work in the lab, but not in the field — where we were getting differences of 100 cfm, possibly due to a large OACF, or possibly due to the home’s unique custom ductwork or the added resistance of a pre-heater (see Image #3, below). Footnote1. Discussing the topic of excellence, Aristotle suggested that “It is the mark of an instructed mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness when only an approximation of the truth is possible.” This observation is useful when considering whether to use the garbage bag test or a Flowfinder. It also makes sense to work with the designer to ensure that the flow measuring stations (Stations 2 and 3) are specified in the design and are clear of turbulent features, and to communicate that requirement to the installer (see Image #1 at the top of the page). Though it probably applies more to commercial systems, Venmar suggests, “If OACF is ignored in the selection process, then the prescribed amount of fresh air will not be supplied to the space and poor indoor air quality may result — in addition to creating numerous potential issues with balancing and commissioning.”For a thorough treatment of the calculations and more explanation of the jargon used above, see AHRI’s “How ERVs Work” section; it is brilliant. I’d also recommend downloading and reading NRC’s pdf for insights into the testing process: “Evaluation of IAQ Impact of Balanced Residential Ventilation devices that incorporate HRV and ERV.” What’s the error range?When I spoke with the top scientist at ACIN Instrumenten (the manufacturer of the balometer) in the Netherlands about our proposed method using the FlowFinder Mk II, the scientist suggested that the error of the method could be a bit higher than 3%. Given the alternative, that sounded acceptable and well within CSA-F326 10.2.1′s suggested ±15% for a quick and painless “no-tin-snip and tape” commissioning. This was progress!Stations 1 and 4 were the same shape. We taped the cardboard flange to the perimeter of the vent in order to get a reasonably good seal with our balometer. The backdraft dampers were not in the hood, but in the duct. Three sequential measurements were taken to account for potential errors due to wind.Armed with flow-measuring stations, Pitot tubes, and our new balometer, we started measuring to find where our TVC might be on the variable-speed control board. This would then allow us to adjust flows room by room — except that the flows in and out of the house were off. Way off. We were recently called to commission a fully ducted energy-recovery ventilation (ERV) system in a newly constructed, “near passive” house.Commissioning an ERV usually involves dialing in the specific ventilation rate on the variable control knob, and then adjusting air flows room by room according to the intended mechanical design. We also needed to ensure that the system didn’t change the pressure in the house with respect to the outdoors. At risk of stating the obvious, mechanical ventilation systems will either pressurize or depressurize a home if not commissioned properly. (See Image #2 at the bottom of the page.)What we thought was going to be a straightforward job turned into a multi-day time-gobbler that taught us a few lessons.last_img read more

How U.S.-China Tensions Could Affect Your Next Smartphone

first_imgOn Monday, the U.S. House of Representatives Select Committee on Intelligence report explicitly called out Chinese electronics corporations Huawei and ZTE as potential national security threats for the United States. The recommendations to avoid products and components from those companies could have wide-ranging effects on U.S. technology companies and buyers. China’s Hard-Core RepThe report drafted by the Committee, recommended “…[t]he United States should view with suspicion the continued penetration of the U.S. telecommunications market by Chinese telecommunications companies” as a backdrop to dealing with all Chinese firms in that sector, and specifically called out ZTE and Huawei.“Private-sector entities in the United States are strongly encouraged to consider the long-term security risks associated with doing business with either ZTE or Huawei for equipment or services,” the report stated.Both Huawei and ZTE have been linked by U.S. investigators as having close ties to the Chinese military, and both companies were accused earlier this year of selling equipment that would relay data back to China… allegations both companies have strongly denied.Huawei and ZTE both vehemently denied today’s report’s conclusions. “We have to suspect that the only purpose of such a report is to impede competition and obstruct Chinese ICT companies from entering the US market,” Huawei said in a statement to the press.Given the lengths that technology companies will go to to protect their markets in the courtroom, it is not so far-fetched to assume that some well-placed lobbyists could exert some influence on House Committee members and paint ZTE and Huawei as bad actors. And that could be what’s going on here.But where there’s smoke, there’s often fire, and as noted, this isn’t the first time suspicions have been raised about relying too much on components from our strategic competitors. For example, a number of private and public officials have long made it a standard practice to take extreme care with their electronics when visiting mainland China to avoid having their privacy and security compromised.The Complex Western Pacific ClimateRocky relations with the increasingly powerful and assertice People’s Republic of China in a U.S. election season further complicates an already tense trade and political situation throughout the Western Pacific. Since the end of World War II, the U.S. has projected a very strong presence in that part of the world, particularly in its relationships with Japan and South Korea, and keeping a balance in trade, resource and security interests in that region of the world remains challenging.The political complexities in a region where billions of dollars of electronics are designed and manufactured (electronics that Americans consume voraciously and that underpin much of our computing and communciations device and infrastructure), are very much a part of the reason why the U.S. is renewing its efforts to establish a presence in Western Pacific, to give all nations in East Asia a clear signal that America is not going away. While the U.S. publicly denies that it’s trying to “contain” China, there is little doubt that that’s exactly what it’s trying to do.Watching The Ripple EffectToday’s Committee report will most certainly cool U.S.-Chinese relations, though listening to both U.S. Presidential candidate’s stump speeches would probably have the same effect. If the rhetoric continues, each side might be tempted to start a more aggressive form of conflict, such as a trade war.If U.S. companies abide by the recommendations of the report, it will be hard to tell what the immediate effects will be. It could prompt re-examining existing agreements with Huawei, ZTE and U.S. partners and would be even more likely to affect deals still in the planning stages.Both companies make parts used to build electric power grids and banking and finance systems, not to mention parts for consumer devices. If any of those parts were critical to the manufacture of other companies’ finished products and were blocked by participation in this embargo, it could create a scarcity that would bump up prices right before the U.S. holiday shopping season.And there’s no telling what China might do in retaliation. The complexities of the Asian markets are layered with many nuances, and the chain of cause and effect can be just as complex.One possible first volley in such a push back could be a slow-down or cancellation of Beijing-vased Lenovo’s recently announced plans to build a new computer manufacturing facility in Whitsett, North Carolina . If that deal’s status changes, it would be a stinging financial and political blow to that region.There is no sign yet that the Lenovo deal, or any other recent U.S.-Chinese deal, will be altered, but it is a possibility. But even if China chooses not to respond directly, U.S. participation in this recommended embargo will undoubtedly affect the global elecronics market and put further stress on gobal economies. Image coutesy of Shutterstock.

Enbridge reports improved second quarter earnings amid asset sales

first_imgCALGARY, A.B. – Pipeline operator Enbridge Inc. reports better-than-expected second-quarter earnings of $1.07 billion, as it worked to sell a number of non-core assets to help eliminate debt.The Calgary-based company’s profit amounted to 63 cents per share and compared with $919 million, or 56 cents per share in the second quarter of 2017. Both quarters included the impact of a number of unusual items.Adjusted earnings came in at 65 cents per share, up from 41 cents in the year-earlier period and beating analysts expectations for 53 cents per share, according to Thomson Reuters Eikon. During the quarter, the company announced agreements to sell $7.5 billion worth of non-core assets, significantly above its original $3 billion target.Enbridge said in May it would gain nearly $3.2 billion by selling renewable power facilities and natural gas gathering and processing assets in the United States.It also received positive news on its Line 3 replacement project, with a Minnesota regulator approving its plan.The company says it is on track to achieve its 2018 guidance and expects about $7 billion worth of new projects to be introduced over the course of 2018, the majority of which will come online in the second half of the year.last_img read more
