    Ohio's corn and soybean crops experienced exceptional growing conditions in 2015, including record rainfall in June and July followed by a drier than normal August conditions in many areas. The persistent rains saturated soils and caused localized ponding and flooding. These conditions resulted in root damage and N loss that led to uneven crop growth and development between and within fields. Agronomists often question the value of test plot data when adverse growing conditions severely limit yield potential.

    This season, farmers are at high risk of having a field fire during corn harvest.

    The conditions present during harvest season include dry plant material and grain dust that are highly combustible.  Hot equipment or engine sparks are great ignition sources.  It is not uncommon for exhaust pipes or catalytic converters to exceed 1,000°F. Add a little wind and there is a perfect opportunity for a field fire.

    Protecting grain quality and ultimately the economic value of the grain begins long before the first acre is ever harvested.  This pre-harvest activity is to prepare grain harvesting, handling and storage equipment and structures for the soon to be harvested corn and soybeans.

    To estimate yield, four soybean yield components need to be considered: plants per acre, pods per plant, seeds per pod, and seeds per pound (seed size).  A printable worksheet to estimate soybean yield can be found by clicking here.  It is difficult to accurately predict soybean yield because of plant variability and fall weather conditions can influence seed size.  Estimates become more accurate as the growing season progresses.

    The end of harvest marks a good time to implement good management practices for yield monitors including taking steps to winterize components.  Yield monitors continue to increase and in most cases are standard options on today’s combines with the yield mapping data being important information for precision agriculture services offered across the agriculture industry.  A good post-harvest combine maintenance plan should include provisions for looking over yield monitor components and possibly storing devices in conditioned locations to reduce warming and cooling cycles potentially generatin

    As the harvest season comes to a close, now is a good time to clean and look over you combine before parking for the winter.  A good post-harvest combine maintenance program can provide significant savings and make sure you are prepared for 2015. Many times, proper inspection and maintenance after fall harvest will reduce time and resources required at a later date to fix the combine and headers.

    There are recommended targets for percent grain moisture and grain temperature for winter grain bin storage.  Those recommended targets are listed in the following tables (Tables 1. and 2.).

    Soybean pod shattering is not completely understood.  Through breeding efforts (beginning approximately 5,000 years ago when soybean was first thought to be domesticated), soybean plants have gained pod shattering resistance (Dong et al., 2014).  However, certain environmental conditions can lead to pod shattering.
