Grain storage and drying issues
With high yields and low prices in 2016, farmers may be looking for additional storage for this year’s crop.
The basics of grain storage, drying, management and care.
Grain storage management
Joseph Zulovich lays out a basic framework for drying and storing grain in Grain Storage: A Systematic Approach (http://extension.missouri.edu/main/spotlight/systematic.aspx). Zulovich is an Extension Agricultural Engineer in the Commercial Agricultural Program and Division of Food Systems and Bioengineering.
For more information on the storage, handling and management of grain, see the MU Extension presentation On-Farm Grain Storage and Drying Considerations (PDF) (http://extension.missouri.edu/webster/documents/presentations/2013-07-30_GrainStorageTour/OnFarmGrainStorageConsiderations_BasicsGrainDrying_EquilibriumCharts-KentShannon.pdf), and visit MU Extension publications:
The MidWest Plan Service (MWPS) also provides additional publications on grain storage and management (https://www-mwps.sws.iastate.edu/catalog/grain-handling-storage), including a publication on Managing and Designing Bunker and Trench Silos (PDF) (https://www-mwps.sws.iastate.edu/catalog/grain-handling-storage/managing-and-designing-bunker-and-trench-silos-pdf). The MWPS disseminates research-based information that supports the outreach missions of the 12 North Central Region land-grant universities plus the U.S. Department of Agriculture.

The Bin Drying Estimator (XLSX) (http://extension.missouri.edu/explorepdf/agguides/agengin/BinDryingEstimator.xlsx) can estimate the time required to dry corn or soybeans stored in a circular bin using either natural air or low-temperature drying practices. The tool estimates the time to dry a wet grain volume or a wet grain layer on top of dry grain.
The Missouri Crop Resource Guide (http://crops.missouri.edu/machinery/) lists helpful information on grain drying and storage, including grain bin and storage cost, the economic returns of grain drying, and grain shrinkage and moisture.
The University of Missouri Commercial Agriculture Program's Horizon Point (http://agebb.missouri.edu/horizonpoint/) functions to make precise weather information available to Missouri farmers in an effort to assist with their daily business. The program has information on grain drying (http://ag3.agebb.missouri.edu/horizonpoint/examplereports/report_m_more.asp) and offers an example grain drying report (http://ag3.agebb.missouri.edu/horizonpoint/examplereports/report_m.asp).

The Grain Volume Estimator (XLSX) (http://extension.missouri.edu/explorepdf/agguides/agengin/GrainVolumeEstimator.xlsx) can quickly calculate the quantity of grain that can be stored in a number of different facilities. Stored grain volumes can be calculated for standard circular bins, rectangular flat storage buildings and a variety of different pile configurations.

With high yields, many farmers are looking for alternate methods for storing a surplus of product. The links below offer varied options for choosing different storage methods.
The Agricultural Electronic Bulletin Board (AgEBB) has its own Grain Storage (http://agebb.missouri.edu/storage/index.php) page, which provides space to either list storage that you are not using or find available storage if you need. Per the AgEBB site:
“Farmers looking for storage facilities could search for available facilities in the region of Missouri where they have needs. If a satisfactory match occurs, it is the responsibility of the farmer to contact the owner of the storage facilities and initiate a rental arrangement. They could also enter a listing describing their need for storage.
Persons with storage can access the listing and search for any farmers who have entered needs for storage. If a satisfactory match occurs, it is the responsibility of the storage owner to contact the farmer and initiate a rental arrangement. Storage owners can also enter a listing describing their available storage.
The listings include names, cities, counties, phone numbers and types of grain storage. People can search for available storage, storage requested or both. Storage types include: bin storage with aeration, bin storage without aeration, flat storage with aeration, flat storage without aeration and other. A final area for notes catches information such as 'easy access to blacktop,' 'auger and dryer available for use,' and 'call after 6 p.m."

Grain storage webinar
On Sept. 8, 2014, regional specialists participated in a webinar on the grain storage issues predicted following this year's near-record yield. The specialists covered harvesting, drying and storing of grain in several in-depth presentations.
- Economics of Grain Drying (http://etcs.ext.missouri.edu/AConnect/Recordings/KristiPerry/20140908-DryingEconomics/20140908-DryingEconomics.htm) — Crop economist Ray Massey covers issues of drying economics including Missouri's grain storage capacity, the relevent costs of drying and analysis tools to help estimate drying costs. He also answered questions (http://etcs.ext.missouri.edu/AConnect/Recordings/KristiPerry/20140908-DryingEconomics2/20140908-DryingEconomics2.htm) about the effect of late drought on regional drying and storage capacity.

- Natural Air Drying (http://etcs.ext.missouri.edu/AConnect/Recordings/KristiPerry/20140908-NaturalAirDrying/20140908-NaturalAirDrying.htm) — Natural resource engineer Kent Shannon discusses considerations for natural drying, including airflow, fan selection, bin size and drying time.
- Estimating the Capacity of Temporary Storage Piles (http://etcs.ext.missouri.edu/AConnect/Recordings/KristiPerry/20140908-PileCapacities/20140908-PileCapacities.htm) — Jim Crawford, natural resource engineer, examines the estimation process for pile capasities and provides spreadsheets and equations to help determine pile size.
- Grain Storage Options (http://etcs.ext.missouri.edu/AConnect/Recordings/KristiPerry/20140908-StorageOptions/20140908-StorageOptions.htm) — Extension agricultural engineer Joe Zulovich discusses various long-term and temporary storage options for grain.
North Dakota State University, AgWeb, Farm Journal Media and DICKEY-john presented the "Importance of Accurate Grain Moisture Analysis" webinar on Sept. 8, 2016. The webinar pinpointed the four most common applications for grain moisture measurements, and highlighted how the type of moisture measurement can affect overall efficiency and profitability.
