Corn Newsletter : 2018-37
Wet Weather AheadAuthor(s): Jim Noel
The weather pattern will support wet weather into the middle of November with a series of storms now every several days. With clay type soils and reduced evaporation this could lead to standing water in fields in the next few weeks. We expect a wet weather system for the middle of this week followed by another next week.
November will be marked with above normal rainfall and temperatures trending from near normal to above or much above normal for the second half of the month.
Rainfall for the next two weeks will average 2-4 inches across the state with isolated higher totals in the south and east sections. A few spots in the northwest sections may be below 2 inches. This is above normal in all areas of the state though and much above normal in eastern and southern sections. See attached graphic for the two week rainfall outlook from NOAA/NWS/OHRFC.
The pattern remains in place with overall wetter conditions into December (though the second half of November may dry out some). It still appears January into February and possibly March will experience normal or slightly below normal rainfall before more wet weather returns sometime in April of 2019.
Much of the state has seen freeze conditions already with only pockets of the state not seeing a freeze yet (like near Lake Erie in northeast Ohio). However, much of the state has not seen a hard freeze yet (though parts of Northwest Ohio have). There is a chance we will go well into November before we see a hard freeze widespread across the state of Ohio.
2018 Ohio Soybean Performance Trials - All Yield Results AvailableAuthor(s): Laura Lindsey
Yield results from all three regions (north, central, and south) are now available online as a pdf at: https://stepupsoy.osu.edu/soybean-production/variety-selection/ohio-soybean-performance-trial Grain quality results and sortable tables will be available in November.
Average yield for the Ohio Soybean Performance Trials by location and trial (early and late) for 2017 and 2018 is shown in the table below. Soybean yield in the north region (Henry and Sandusky County) was much greater in 2018 compared to 2017. (Yield from Henry County was not reported in 2017 due to extremely wet weather causing yield to be variable.) In the central region, soybeans in the early trial yielded greater in 2018 compared to 2018. However, in the late trial, soybean yield slightly decreased in 2018 compared to 2017. Yield in the south region was variable with Preble County yielding less in 2018 compared to 2017 while Clinton County yielded greater in 2018.
FARM: Field Application Resource MonitorAuthor(s): Aaron Wilson
One of the missions of the State Climate Office of Ohio (SCOO; https://climate.osu.edu) is to serve as data stewards to connect Ohioans with the weather and climate information necessary to improve lives. In an effort to provide farmers across the state with sufficient weather guidance, specifically to aid in decisions regarding the application of fertilizer and manure, SCOO has developed FARM, the Field Application Resource Monitor (https://farm.bpcrc.osu.edu/).
FARM is a web-based, mobile friendly tool that provides:
- Real-time high resolution precipitation forecasts to field(s) of interest (up to five locations),
- Historical precipitation forecasts (back to July 2017),
- Daily email notifications if desired (text alerts coming soon).
Originally designed in response to Senate Bill 1 regulations for the Western Lake Erie Basin, FARM can help any farmer throughout Ohio follow best management practices with regard to their precipitation forecast needs.
Precipitation forecasts in FARM are provided via the National Oceanic and Atmospheric Administration’s Weather Prediction Center (WPC). We utilize the probabilistic forecasts which are based on a combination of WPC's 6-hour quantitative precipitation forecasts and an ensemble of model forecasts. This data is available on a 1.5 mile x 1.5 mile grid, meaning FARM provides precipitation guidance on a local scale.
Again, FARM can be found by visiting /farm.bpcrc.osu.edu/. For more information on creating user profiles, returning, and other features of FARM, please check out http://u.osu.edu/farmprecip for a full tutorial. We have also provided a feedback button on the initial screen and request feedback, suggestions, and improvements as we continue to improve our product.
On the opening screen (first image on the right), users are presented a number of options (yellow arrows) including "View as a Guest", "Create User Profile", and "Returning User."
After selecting "View as a Guest," users will be presented with the following screen:
This is the Field Set-up screen. Here, users will provide the necessary information to locate and delineate the field(s) of choice.
FARM users have the option to select "By Address" or "By Coordinates," and must provide a name for the field(s), enter the address (or latitude and longitude coordinates), then select "Search" (blue arrow).
Another options is to select the "Use GPS" button (blue arrow) and the site will detect the user's current location (if enabled) and zoom into the area of interest. Finally, clients can zoom into their area of interest using their device's normal zooming capabilities.
Once users have zoomed in and named their field, it is time to draw the boundaries to the field or pin their desired location with a marker (below).
To use the polygon tool, select the polygon button (yellow arrow), click the desired number of points surrounding the field, then selectfinish or click on the first point that was placed. This will complete the polygon, and a blue outline will appear around the field.
To use a pinpoint location, select the marker button (blue arrow), and then click on the desired location. Once the field has been delineated, click "Save Field" (red arrow).
This will take users to the FARM Dashboard (below). This is the main source of information regarding precipitation forecasts, and there are several key features to point out.
1. (Yellow Arrow): This provides the time for which forecast conditions are displayed. The default is the forecast nearest the current time.
2. (Blue Arrow): This displays the current precipitation forecast, at the 50% chance criteria for 12 and 24 hours. Based on this information, a red-light/green-light icon will appear for both fertilizer and manure. These indicate when applications of these materials are either regulated by state law (where applicable) or not recommended as a best management practice.
3. (Red Arrow): This section displays a three-day forecast for your field area, with high and low temperatures, and the overall chance of precipitation displayed below.
4. (Green Arrow): A major component of FARM is the ability to pull a previous precipitation forecast. Clicking in the date box will allow you to select a previous date (back to July 2017) and time (scroll bar on the side). One you hit "Submit," the precipitation forecast for that date and time will be displayed. To return to the current forecast, select "Current Forecast."
5. (Purple Arrows): Those desiring to add additional fields to their dashboard (up to 5 fields) may do so by selecting "Add New Field." Repeat field delineation procedure described above. After completing these steps, users will be returned to their dashboard. All fields will now be displayed on your dashboard.
6. Two additional features to note:
- The green/red indicator in the upper right of the screen represents the number of fields where conditions are/are not recommended for application based on the precipitation guidance near the blue arrow.
- Users may also delete or change the name of their field(s) by selecting "Edit" next to the field name.
IMPORTANT NOTE: If after setting up the field(s) as a guest, users decide that they would like to save their profile, simply return to the home screen by selecting "FARM" at the top of the screen, and select “Create User Profile.” Any fields selected during the “View as Guest” session will be saved to this newly created account. Registered users can receive email notifications (text alerts coming soon.)
