resistance of the grain itself but not the duc ng. However, the resistance due to duc ng does not account for all of the differences between the measured and predicted values. The difference between measured and predicted airflow resistance values was greater for len ls than peas, sugges ng that the resistance to airflow model should be adjusted for len ls. Equilibrium Moisture Content Equilibrium Moisture Content (EMC) charts are available in literature for peas, red len ls and len ls. The in- grain temperature and humidity data collected in year one was used to calculate the moisture content of the grain using these EMC models and compared with the actual moisture content of the samples collected from those bin loca ons. The EMC chart for len ls predicted moisture contents that were from 5% under to 3% over the actual moisture content. The moisture content calculated from the red len l EMC chart was consistently 3% to 4% under the actual moisture content. The moisture content calculated from the pea EMC chart ranged from 2% under to 5% over the actual moisture content. Therefore, these EMC charts may be used as a general guideline to understand how air condi ons may affect grain moisture content, but adjustments are required if they are to be used for precise control of fans for drying. Studies like this one may lead to another predictor, absorp on poten al, which may be a be er indicator of the air's capacity to dry. Year Two Research The trials will be repeated in 2018 to validate these findings and collect data on drying and cooling over a (hopefully) different range of ambient condi ons. Len ls with a higher moisture content will be targeted and the effect of drying on seed quality will be more rigorously evaluated. The Bo om Line With only one year of data, it is too early to draw conclusions, but the fact remains that producers must ensure enough airflow to remove moisture. If pulses are harvested early in the season, fans for cooling should be run immediately and over a longer period un l ambient condi ons are able to cool the seed to 15°C. However, producers must exercise cau on because over-drying can downgrade quality through cracking or spli ng. Figure 4. Pea airflow resistance at various grain depths. 2 6
