Share Facebook Twitter Google + LinkedIn Pinterest Ohio State University corn nitrogen rate recommendations follow a unified framework used throughout the Corn Belt. Together with six other states (Iowa, Illinois, Indiana, Michigan, Minnesota, Wisconsin), the Ohio recommended nitrogen rates are not based on yield goals, but on economic returns. Corn yield responses along with corn and nitrogen prices are used to calculate the point at which the last unit of added nitrogen returns a yield increase large enough to pay for the added nitrogen cost. This approach, called the maximum return to nitrogen (MRTN), is favored because of the economic volatility in both corn grain and nitrogen fertilizer prices. The past 10 years provides ample evidence of these fluctuations.The MRTN interface requires 3 inputs: i) the previous crop grown (corn or soybean), ii) price of nitrogen fertilizer, and iii) price received per bushel of corn. When corn prices are low, nitrogen rates will be reduced; when corn prices rise, recommended nitrogen rates will increase. Similarly, the model responds to nitrogen prices, recommending high nitrogen rates when nitrogen costs are low, and reduces rates when costs are high. The model is housed on an Iowa State University website coordinated by Dr. John Sawyer, but each state provides their own yield response data and some support for website maintenance and updates. When a user selects Ohio as a state, they will only find data collected from trials in Ohio. The tool can be found here: http://cnrc.agron.iastate.eduPreviously there were 116 trials from Ohio (80 trials with corn after soybean, and 36 trials with corn following corn). After this major update, there are now 281 trials in the database (228 trials after soybean, 53 after corn). This database update is part of the comprehensive revision of the Tri-State Fertilizer Recommendations, with major support from the Ohio Corn and Wheat and the Ohio Soybean Council. With help from farmers, Ohio State University extension county educators and numerous private crop consultants, we conducted 56 nitrogen rate trials over 20 counties across the state from 2015-2017. Additional trial data came from OSU extension and from the Adapt Network project, coordinated and supported by the Environmental Defense Fund. These data trials were all independently analyzed and vetted before inclusion into the database. This represents a tremendous collective effort and countless hours of work by many committed professionals working toward a common goal. The recommended nitrogen rates can be found in the table below.Recommended nitrogen rates (lb nitrogen/acre) for corn following soybean, based on price of corn grain and nitrogen fertilizer.Additional analyses are now being conducted to look at trends with soil type and regions in the state. We’ll see if it is justified to split the state up into separate regions.Selecting rates to maximize profitability and not yield can be a difficult mindset for the farming community to break. Farmers love reporting big yields from their fields. However, we need to understand that maximizing yields usually translates into reduced profits and greater nutrient losses from the field. Now more than ever, we as a farmer community need to continue to proactively address water quality issues in the state. We trust that farmers and retailers can use this information to look past maximum yield and a reduced bottom line, and instead choose profitability and sound nutrient management when selecting how much nitrogen to apply to their corn crop this season.

After claiming their business through the Google Local Business Center, business owners can now easily post short updates about their companies on their respective Place Page. In addition, businesses that have been claimed by their owners will now feature a badge that highlights the fact that the actual owner of this business has claimed and improved the page.With Place Pages, Google aims to offer “a webpage for every place in the world.” Most users access these pages through searches on Google Maps. As Google points out in today’s announcement, business owners can use the new “post to your place page” feature to post updates about their businesses directly from their dashboards. This gives local businesses the ability to send out updates about new products or – in the case of local restaurants – to highlight daily specials and new menu items.It’s also good to see that Google is now giving local business owners the ability to make it clear that they have claimed their Place Pages and improved them with updated information (opening hours, phone numbers, etc.). Even though Google is quite good at generating this information automatically, getting the information directly from the business owners is likely to improve the quality of these listings and will make the information more trustworthy.

She plays the romantic lead opposite debutant hero Vinay Virmani in the film, which revolves around ice hockey.”Shooting for the film helped me understand Indian culture. Coming to India after this film, I am getting to know and understand the cinema of this country and the wonderful people here. Right now, I am simply enjoying Indian food,” she said at the do, hosted at the Canadian high commissioner’s residence.Camilla, who said she had “a blast shooting this film”, courtesy of the novelty of Indian cinema, added: “I am ready for Indian films but it all depends on the offers I get. I am in love with Bollywood and am learning Bollywood-style dancing right now.” At the event, Akshay was seen playing a doting godfather to Camilla. ” Bollywood projects for her also depend on her dates because she is a busy actress in the West,” he said about Camilla, who has also starred in Hollywood features such as 10,000 BC and When a Stranger Calls. Akshay, who is the brand ambassador of Canada Tourism in India, shot the entire film in Toronto and Vancouver. Akshay Kumar is sure that Speedy Singhs, which tells the story of a bunch of Canadian Sikhs who go on to excel in the sport of ice hockey, will be liked by the Indian audience. “Ice hockey will be a unique experience for the Indian audience. Also, people will enjoy the sport-based theme of the film set in scenic Canada,” he said.The movie was earlier titled Breakaway. “The word breakaway is a specific technical term used in ice hockey. We felt the Indian audience wouldn’t connect with the term and changed the name to Speedy Singhs,” said Akshay, explaining the name change.The film also marks the debut of noted Canadabased stand- up comedian Russell Peters, who plays a prominent role in the film. ” I have been working in films since 1994 but I never got a chance to work in an Indian film so far.They never had a role to suit my personality. Speedy Singhs has a funny character that suits me and is, at the same time, in sync with the story, so I did it,” said Russell. advertisement read more
