20 GRAIN MONITORING CAPABILITY is keeping pace with the digital age with more in-depth sensor networks and the capacity for automation; however, that does not mean old school methods have no role. Manually inspecting grain inside the bin, or as it flows into storage, is still critical. CABLES – THE CURRENT STANDARD James Dyck, crop systems and environmental engineer specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), says in-bin cables are the most widespread and well-established monitoring systems in current use. Designed to hang from bin ceilings, such cables feature multiple points of interaction to measure moisture and temperature at varying levels within the grain mass. Cables can be used individually or in a network — the latter generally being employed in larger storage structures. With an internet connection, gathered data can be communicated directly to operators. Cables can likewise be linked to fans which could be set to automatically engage if the data indicates aeration is needed. The limitation of cables, says Dyck, is their inability to measure grain quality beyond a very localized area around the sensors. Grain monitoring in a digital world CURRENT AND FUTURE TOOLS Matt McIntosh “If something is happening six feet away from the cable it’s going to take time for it to get large enough for the cable to detect it…the cable doesn’t replace the need to manually monitor your grain once in a while.” FROM PROBES TO NETWORKS Recognizing the need for a more complete picture, Dyck says tools which analyze the bin as a larger network are now available. Manitoba-based company GrainViz, for example, markets a monitoring product which measures moisture via sensors installed across bin walls. Dyck says the systems gives “an MRI scan of interior Agronomy MANUAL MONITORING — TRIED AND TRUE STRATEGIES • Use your eyes: From an aperture on the roof or side, look at the grain mass for wet spots on the surface, potential insect damage, and whether condensation is present. • Use your nose: Turn on the blower and be mindful of foul odours whichmight be emanating from quality issues within the grain mass. • Use them often: Environmental factors both inside and outside the bin affect risk level. Monitoring intervals can stretch up to six weeks in cold months, but in warmer weather, monthly or biweekly checks are preferrable. Don’t assume everything is fine because grain entered the bin in good condition, and under good conditions. • Use your brain: Always put safety first. Do not enter grain bins unnecessarily. If an individual has to enter the bin for any purpose, ensure all proper safety precautions are taken.
