Why a moisture tester?

*Accurate moisture tests are important in managing and marketing grain. Inaccurate tests can lead to:

  • spoilage if grain is too wet and is placed in low-temerature (air heated less than 10 degrees F) or natural-air drying bins
  • extra drying cost and combine loss if grain harvested is wetter than necessary
  • moisture shrink and drying charges when grain sold too wet
  • extra drying cost and loss of value (about 8.9 cents/bu./point for $4.00/bu. corn) when grain is dried below the market standard
  • spoilage when grain is stored too wet
