From Moisture To Harvest, What You Need To Know

Everyday is filled with questions, when it comes to farming that is no different. One of the most asked questions by farmers is, “What is the ideal moisture content for harvesting?”. The answer to this question can have a major impact on storage, crop profitability, and crop storage. Whether you're harvesting corn, soybeans,  wheat, hay, or other forage crops, this article is for you. 

Farming is a never-ending balancing act of predicting the unpredictable. No two seasons are the same, understanding the ideal harvest content moisture for your crops can help protect your yield, improve quality, and maximize your profits. We’re here to make your job a little easier by sharing tips, insights, and information from the amazing world of agriculture. 

Corn 

The ideal moisture content for harvesting is 20 to 25% for dry grain storage. This helps minimize field and mechanical losses.

• 15.5% or lower for safe standard market storage

• Corn intended for livestock feed should be harvested at 24 to 33%

• 62 to 68% for corn silage harvest

Soybeans

 Soybeans should be harvested at 13 to 15%. 

• Below 12% causes high shatter loss, split seeds, and brittle pods.

• Above 18% bruise and damage seeds during threshing. 

If you're wanting to store your soybean crop for long-term, your ideal moisture content level is 11% or less. 

Wheat and Small Grains 

They recommend 13.5% when harvesting wheat and other small grains.

High levels put you at risk for elevators to dock your price or reject your crops all together due to excessive moisture. For safe long-term storage, grain should be dried  to 12.5 to 13%. 

Hay/Forage

Hay and other forage crops are best harvested at 15 to 18%.

•  Higher moisture puts your crop at risk for mold, combustion fires, and nutrient loss.

•  Lower moisture levels cause dry-matter loss and excessive leaf shatter. 

Why does knowing the ideal moisture content for harvesting matter? 

Knowing the ideal moisture content at harvest is one of the simplest ways to protect your investment. Harvesting at the proper moisture helps: 

• Maximize crop quality and market value 

• Reduce mechanical and field losses

• Prevent spoilage during storage 

• Improve storage safety 

• Preserve yield and profitability 

From the field to the bin, the right moisture level can make a significant difference.
