Planter in-cab display terminology

first_imgShare Facebook Twitter Google + LinkedIn Pinterest The planting operation is arguably the most important field operation since it establishes maximum yield potential of a seed when placed in the soil. In terms of planting performance, four factors of focus to maximize yield potential and are at the control of the planter operator are 1) population, 2) uniform spacing, 3) uniform emergence, and 4) planting timing and field capacity. Three of these four important factors, population, seed spacing uniformity, and field capacity (ac/ar) can be directly monitored during the planting operation from the in-cab display.This and other information is provided by new in-cab displays providing the operator real-time feedback. Precision planter technology can help monitor and ensure population and spacing expectations are being met during field operations. This real-time feedback also provides opportunity to the operator to make timely adjustments or most importantly make sure seed is being placed properly to maximize yield potential. Many planter displays today provide additional meter, planter and tractor parameters that can be valuable feedback to the operator along with data (e.g. as-planted data) for post-planting analyses.One issue with in-cab planter displays is determining what all this information means and how it can be utilized to its potential. Each planter or in-cab display manufacturer uses different terminology. To help with understanding the information being provided by today’s displays, a group of university and industry professionals are working on a publication that lists the terms and associated definitions so users can better understand all this data being displayed and collected. The first list of terms is currently being reviewed by the group and should be published later this year.Here are a selected few terms and definitions related to the four factors of attention at planting:Plant population (also referred to as population, planted population or target population): A general term that indicates the target or actual number of seeds planted per acre.Live population (also referred to as emerged population or live stand): A general term indicating the population or number of seeds per acre that emerge. Live population and planted population are used to determine the percent of seeds emerged which is commonly referred to as “Emergence percent.”Singulation: the percentage of seeds properly singulated by a seed meter. The singulation value takes into consideration seed skips and multiples. The higher the singulation value the better and it is typical to have singulation values of 97% or higher for precision planters.Spacing (seed spacing): the distance between two successive seeds in the row. The spacing is measured for an individual row using a seed tube sensor during field operation. Seed spacing is commonly used to evaluate planter performance by the operator as it represents the ability of the meter and delivery system to consistently deliver seed at a preferred spacing to the seed furrow. Variability in seed spacing expressed as standard deviation or Coefficient of Variation (CV) is typically used to monitor planter performance.Seed spacing standard deviation: computed as the variation in spacing between consecutive seeds. This variation can be used to evaluate planter performance. A standard deviation of two inches or less represents an attainable variation in spacing by most planters. But one should remember a standard deviation of two inches is different for varying populations.Plant spacing: the distance between two successive emerged plants in a row. This is typically measured over a known distance to determine final mean plant spacing and evaluate plant spacing uniformity expressed as standard deviation or Coefficient of Variation (CV).Ride quality (also referred to as ride dynamic or good ride): indicates the level of vertical movement (e.g. bouncing) by a row unit. Displayed commonly as a percentage of time when ride quality is sufficient to not impact seed spacing. A 100% good ride (e.g. no vertical movement thereby a smooth operation) represents optimum row unit ride quality and 0% represents the poorest ride quality.Applied down force: the amount of weight applied by the planter row unit and downforce system, either pneumatic or hydraulic, onto the row unit for coulter or pair of disc to achieve right depth and gauge wheel to carry enough load for desired soil compaction during the planter operation in the field.Down force margin: margin represents the amount of extra down force applied to row units, over and above what is required for opener disks to penetrate the soil and achieve full planting depth. The extra down force comes from the weight of the row unit and meter, weight of seed in the seed hoppers, and the down force system.Once the publication is reviewed, it will be provided online through the Ohio State precision agriculture website, www.OhioStatePrecisionAg.com. Dr. John Fulton, Associate Professor, can be reached at 614-292-6625, or fulton.20@osu.edu.

New American Home 2010 Takes a Bow

first_imgBack in August, we noted that the New American Home 2010, originally scheduled for completion well before January’s International Builders’ Show in Las Vegas, was stuck in construction limbo because the lender for the project’s builder, Domanico Custom Homes, fell victim to the credit crunch.The project was about 60% complete by the end of August, and about 75% done by the time the IBS kicked off on January 12, which meant the building was far enough along to make it tour-worthy. In any case, the incomplete structure – for builders and remodelers at least – may be more interesting than one with all fixtures and finishes in place.Built to the National Association of Home Builders’ Green Building Standard and the Department of Energy’s Energy Star Homes standard, New American Home 2010 is designed to be a showcase of energy efficiency. Among its features: an unvented, air-sealed attic with R-30 spray foam insulation on the underside of the roof deck, R-23 ICF exterior walls with an R-7 exterior finish and insulation system, an HVAC system offering 95% annual fuel utilization efficiency, airtight ductwork, an energy recovery ventilator, solar hot water, a tankless water heater, and a 10.5 kW solar power system.NAHB has highlighted Domanico’s frustration with the credit squeeze as an illustration of industrywide concerns over acquisition, development and construction lending. NAHB also sees the project as a nod to downsized expectations in some segments of the luxury housing market, noting, for example, that New American Home 2010 is, by the standards of other homes presented in the series, relatively small. In fact, this five-bedroom single-family, with 6,078 sq. ft. of interior space, is ideal for a family of eight or nine, and it puts its energy efficiency and renewable-energy components on high-profile display. As green-construction advocates will point out, though, it loses green cred by virtue of its scale. Along with the exterior photo we’ve shown before, we’ve included here some progress photos and descriptions from a DOE press release issued in December.last_img read more

Integrity In Your Pipeline

first_imgOne surefire way to miss your goals is to have a pipeline that lacks integrity. The lack of integrity isn’t intentional. No one is really lying about their pipeline. Mostly, there is just a lack of rigor around opportunities. Here are a few of the root causes that you need to remove if you want a pipeline you can believe.Bad Dates: No client will ever tell you that they need to close a deal on the last day of the month, the last day of a quarter, or the last day of the year. Those as “salespeople dates” used as a placeholder for the date by which they believe they can wrap up a deal. A client may, however, want to go live on the first day of a quarter or a year, in which case, their contract will likely need to be signed some time before, allowing time to get through the process.Too Old: Problems don’t age well, and neither do deals. The age of a deal can tell you whether you are looking at something you have a shot of winning. If the deal has been in the pipeline long enough to have its third birthday or has covered two Presidential elections, it’s not something you want to bet on in most cases.Bad Deals: If a deal should have been disqualified, it doesn’t belong in your pipeline. A fast “no” to bad deals is much better—and much healthier—than a slow “no” to those same deals.Wrong Stage: Some of the aging deals in your pipeline may become your client someday. You may have deals that look they have progressed to the point where your prospect will make a decision even when that decision is still far away. The optimism that causes one to believe they are going to win a deal might be well-founded. That said, just because you gave a prospect a proposal don’t mean they are prepared to sign a contract. If you skipped some of the commitments in this book, you may need to go backwards to go forward.A pipeline that lacks integrity can give you a false sense of confidence, causing you to believe that you are closing to your goals than you are. A bad number that is true is less damaging that a good number that is false. It can also prevent you from recognizing what you need to do to produce the results you want. Essential Reading!

Disappointing start for India at Jr NBA World Championships

first_imgOrlando (US), Aug 8 (PTI) In a dismal start for country at the inaugural Junior NBA World Championships, the Indian boys and girls teams lost their respective pool matches on the opening day of the Under-13 and Under-14 basketball tournament, here. The Indian girls, representing the city of Bengaluru, were hammered 11-57 and 28-75 by Asia Pacific and Europe respectively in their two pool matches of the international category at the ESPN Wide World of Sports Complex inside the Walt Disney Resort. The Indian boys from New Delhi fared much better but they also ended up on the losing side in both their pool matches. The Indian boys lost 34-75 to the combined team from Europe in their first match before succumbing to a 43-80 defeat against the Asia Pacific side later in the day. The presence of NBA star Brook Lopez and his family, who were there to cheer for the Indians, failed to inspire the Indians as they failed to match their rivals both in terms of quality and physical fitness. However, the Indians, both the girls and boys, put on display some fast moves and occasional shooting but it was not enough to save them from defeats. Both the Indian boys and girls teams will take on the combined team from South America respectively in their last pool matches tomorrow. But the sheer exposure to be part of the global event in basketball’s heartland will do a world of good in lifting the confidence of the young Indian cagers.
