Corn competition can leave yields on the losing end

first_imgShare Facebook Twitter Google + LinkedIn Pinterest John BrienThe corn field is the prime example of competition — there are 30,000 plants competing against their neighbor for the limited resources of water, sunlight and nutrients. With most competitions there are winners and losers and there are those who are trying to gain a competitive advantage. But, in a corn field the goal is to keep the playing field as even as possible so all the corn plants win. Believe it or not the even playing field begins at emergence.Why does emergence affect the uniformity of the playing field? When corn plants emerge at the same time, no one corn plant has a competitive advantage over another corn plant. But, those corn plants that emerge later than their neighbor are at a distinct and noticeable disadvantage. When it comes to pressure from weeds corn plants are not very competitive, but other corn plants can also cause major competition. The early competition between corn plants will actually cause the disadvantaged corn plant to switch gears and go from yield maximization to pure survival. The switch in priorities can be noticed in every corn field by simply looking for plants that have significantly smaller stalks and look spindly. These are the corn plants that are competing for survival, not to maximize yield.To achieve high yield potential with uniform emergence, what is considered to be an ideal emergence window? An emergence window is measured by counting the hours from when the first corn plant emerges to when all of its neighbors emerge. The amount of time for that first seed to emerge is not the critical issue; the timing of all the neighbors emerging is the issue. In a corn field there are few absolutes, but they do work on a good, better and best formula. A good emergence window is 48 hours; a better window is 24 hours, while the best window is 12 hours long.While the idea of a tight emergence window is great in theory, how can growers help improve their emergence window timing? That involves a four step process:1. A tight window starts with a uniform planting depth2. Planted into uniform soil moisture3. At a uniform soil temperature.4. With uniform soil to seed contact.Here are some suggestions on how to put these steps into practice:A tight window starts with a uniform planting depth and uniform planting depth begins with checking every row of the corn planter to ensure all the rows are placing the seed at the same depth. Every row of a corn planter has its own personality and will place seed at different depths even when they are all on the same setting.Plant into uniform soil moisture at 1.75 inches to 2 inches deep to ensure that the soil moisture is uniform and not negatively affected by any tillage, soil color and/or texture. Any shallower planting depths do not provide uniform soil moisture and can lead to sporadic emergence.Soil temperatures can have dramatic swings throughout the day. The degree and magnitude of those swings will vary on the planting depth. Corn planted less than 1.5 inches deep can experience dramatic changes in temperatures from hour-to-hour and day-to-day that can lead to less than an ideal germination window. A planting depth of around 2 inches provides a much needed buffer to keep soil temperatures stable and conducive to uniform emergence.Soil to seed contact dictates how quickly and how uniformly seeds absorb enough water to germinate. If all the seeds are not given the same opportunity to absorb water, uniformity will be affected. Check down pressure on every row to ensure they are all functioning at the same level and ensure closing wheels are aligned properly over the center of the row to ensure uniform pressure.A tight uniform emergence is the goal to help corn plants start with a high yield potential. A few small steps to ensure that every seed has access to uniform soil moisture, soil temperature and soil to seed contact will give every seed the same opportunity for success.last_img read more

Most Organizations Now Use Open Source Software According to Gartner

first_imgCognitive Automation is the Immediate Future of… IT + Project Management: A Love Affair Massive Non-Desk Workforce is an Opportunity fo… More than half of the 517 organizations surveyed by Gartner use open source software (OSS). When the firm first started tracking open source in the enterprise five years ago, only 10% of organizations were using OSS. Gartner published the results in a report titled Survey Analysis: Overview of Preferences and Practices in the Adoption and Usage of Open-Source Software. This announcement summarizes the findings. Decision makers aren’t just looking to OSS because it’s cheaper – they’re also trying to gain competitive advantages through open source. “Nearly one-third of respondents cited benefits of flexibility, increased innovation, shorter development times and faster procurement processes as reasons for adopting OSS solutions,” reads the announcement.More than one in five respondents (22%) are using OSS in all departments of the organization, while 46% are using OSS for specific departments. According to the announcement, the top uses for OSS were “data management and integration; and application development, integration, architecture, governance and/or overhaul.” Other popular uses were security and compliance, data center modernization and virtualization.Last year we reported an Accenture survey that found that 40% of organizations planned to migrate mission-critical software to open source within a year. It appears that this might be happening quicker than thought, though Gartner includes non-mission critical deployments in its figures.For a look at some of the most popular open source applications in the enterprise, check out this post. 3 Areas of Your Business that Need Tech Nowcenter_img Related Posts klint finley Tags:#enterprise#Trends last_img read more

Blackmagic Announces The Pocket Cinema Camera 6K – EF Mount

first_imgThat was my original intro, for this article, and I didn’t expect to actually use it, but here we are. Blackmagic CEO Grant Petty first apologized for the delay in shipping the Pocket 4K and then announced a new version of the pocket camera. Feedback from tradeshows and filmmakers revealed that users wanted a native EF mount, and that’s something we have covered ourselves for those who purchased the 4K camera to pair with the Ursa (which can natively be EF). It’s interesting to hear this announcement just days after Metabones released their EF to MFT Speed Booster specifically designed for the Pocket 4K.The new 6K camera, which is titled the Blackmagic Pocket Cinema Camera 6K, has a 6144 x 3456 Super 35 sensor and EF lens mount. It has exactly the same design as the Pocket 4K, but there’s a slight difference in aesthetics on the front of the camera. With the larger EF mount, the camera protrudes outward slightly.However, the rear of the camera is exactly the same as the Pocket 4K, and it also houses the same Blackmagic OS. Therefore, if you’re shooting with the Pocket 4K and Pocket 6K, you wouldn’t get mixed up with the menu system when hopping between the two cameras. However, we do have a few new operating settings.Of course, there’s the choice of the 6K resolution, but you can also film up to 120fps windowed at 2K. With the Pocket 4K, you can only film 120fps at 1080p windowed.Another new addition to the Pocket format is that you can work in true anamorphic 6:5 using anamorphic lenses in 3.7K 60 fps at 3624 x 3020. Inside, the camera has the exact same color science as the Pocket 4K, so you can cut and match footage from the pocket 4K with no notable difference. With the larger sensor, users can get a shallower depth of field. A feature that isn’t as apparent with MFT sensors.Notably, we recently covered the topic on taking photographs with the Pocket 4K and how it wasn’t ideal because of the 8.8-megapixel sensor. Since the Pocket 6K has a 21.2-megapixel sensor, this cinema camera now has a significant still function which may rival some professional mirrorless cameras with an adequate video mode.The camera is out today, and it costs $2,495. It will be intriguing to see those who order the 6K today receive their camera before those still waiting for their 4K.  As always, we’ll keep you updated with tricks and tips over the next few weeks.

Well, today, Blackmagic released the Pocket Cinema Camera 6K. Here’s what we know so far.In keeping with their typical cryptic style, this week, Blackmagic announced that come Thursday at 12 PDT, we would be receiving news about new developments in cameras and post-production. Typically, the filmmaking community has a solid idea about what to expect, but comments and ideas have been oddly quiet this time around. If anything, given the delay Pocket 4K owners experienced, users were worried that Blackmagic was going to pull an “Apple” and outdate a camera many have only just received.last_img read more
