A moisture content of about 13% at harvest is optimal for mitigating mechanical damage. Harvesting during high humidity, such as early morning, late evening, or in damp conditions, may reduce shatter loss and mechanical damage if the soybeans are below 11% moisture content.

What moisture do you harvest soybeans?

Harvesting soybeans at a moisture content between 13 and 15 percent helps maximize weight while minimizing harvest losses. Spoilage during storage is a concern when moisture levels are high.

What moisture should soybeans be stored at?

For winter storage, store commercial soybeans at 13% moisture or less. Soybeans with less than 15% moisture can be dried with bin fans. Soybean seed stored over one planting season should be 12% moisture or less.

How much moisture do soybeans need?

The optimum harvest moisture range is 13 percent to 15 percent for maximum weight and minimum field losses. Soybeans can generally be harvested any time after the seeds are mature and the foliage is dry. But threshing is difficult and more beans are crushed and bruised when harvested with more than 18 percent moisture.

How wet can you cut soybeans?

Soybeans can be harvested successfully as long as the moisture content is 20% or below. However, harvesting above 13 to 15% grain moisture plant stems will be difficult to cut, so ensure cutter knives are sharp and the cutter bar is in good condition.

Can you air dry soybeans?

The answer is: Yes! Natural air drying is a great option, especially for IP soybeans. IP beans can scorch and discolour in a heated-air dryer, which could cost you the premium. Some IP growers have had success drying beans with air temperatures around 85°F, but get permission from your buyer before attempting.

What is the best moisture to harvest corn?

The optimum harvest moisture content for corn is around 23 to 25%. At this moisture content range, kernels generally shell from the cob easily. During harvest time, kernel moisture content loss averages about 1 to 2%/day.

How do you dry wet soybeans?

Soybean producers are paid based on the gross weight of the load they deliver minus the moisture shrink when grain moisture levels exceed 13%. Most grain buyers use a moisture shrink factor of 0.7 or 0.8% for each half percent of moisture above 13 percent to convert gross weight to dry weight.

How do you add moisture to soybeans?

While adding water to soybeans to increase their moisture content is illegal, producers can boost the moisture content by aerating the beans with humid air, provided they have enough time and a high enough airflow per bushel, Hellevang says.

How long can dry soybeans be stored?

Properly stored, dried soybeans beans will generally stay at best quality for about 2 to 3 years at normal room temperature, although they will usually remain safe to use after that. To maximize the shelf life of dried soybeans beans, keep the package tightly closed at all times.

What percent moisture is corn dry?

The standard moisture for corn is 15.5 percent, so when grain is delivered at greater than 15.5 percent grain moisture, the weight is adjusted down. (This reflects the remaining weight when the grain is dried to 15.5 percent moisture, losing water weight in the process.)

Do you have to dry soybeans?

For proper storage, soybeans need to be dried to at least 13% for short-term storage and at least 11% for long-term storage. Soybeans harvested at less than 15% moisture can generally be dried with fans that are sized for routine aeration (0.1-0.2 cfm/bu.). Above that, likely requires low-temperature drying.

Can you harvest soybeans in the rain?

Soybeans grown for seed should be harvested at moisture levels near 13 percent to optimize seed quality. The risk of reducing seed quality increases significantly as the moisture level in the seed falls below 10 percent, so seed producers should wait for rain if moisture levels are below 10 percent.

How much will soybeans dry in a day?

During the first 12 days after maturity, the average dry down rate was 3.2 percent per day, which is about five times faster than that of corn. After that period, the dry down rate significantly slows down or stops completely, stabilizing at about 13 percent moisture.

What is low moisture corn?

According to Iowa State University, harvest loss is lowest when corn kernel moisture is between 19 and 23%. As we get below those moisture levels, we begin to see an increase in potential harvest loss, with most of that loss being from shelling at the combine head.

What is high moisture corn?

High-moisture corn refers to corn harvested at 24 percent or greater moisture, stored and allowed to ferment in a silo or other storage structure, and used as feed for livestock.

What moisture is corn at black layer?

The kernel moisture content at black layer formation usually ranges from 30% to 35% (Figure 1). Figure 1. As the milk line diminishes, moisture drops from 55% to near 30% moisture. The formation of a black layer where kernels meet the cob signifies physiological maturity.

Will soybeans freeze dry in the field?

Soybeans that experienced severe frost/freeze damage extending well into the crop canopy will dry down slowly. … In fields where only the upper leaves were damaged by frost, wait and allow the beans to mature and dry to 14% to 15% in the field if possible.

How do you dry grain in a bin?

Grain Drying 101 In deep-bed drying systems (in-bin drying), air is normally pushed through the grain from the bottom of the bin and is exhausted out the top of the bin. As the air moves through the grain, moisture evaporates from the grain into the passing air.

Can you dry soybeans in a grain bin?

It estimated the days to dry soybeans in a grain bin using natural air and 1 cubic foot per minute per bushel of grain in the bin. When drying in the bin, avoid using the stirator as it can damage soybeans. As you can see in Table 1, weather conditions are a huge factor in how long it takes to dry grain.

What temperature do you dry soybeans at?

Typically the maximum drying temperature for nonfood soybeans is about 130°F. Even at that temperature, some skins and beans will be cracked. One study found that with a dryer temperature of 130°F, 50% to 90% of the skins were cracked and 20% to 70% of the beans were cracked.

How do you adjust moisture yield?

1. If initial grain moisture is 20%, initial dry matter content is 80% (100 minus 20).
2. If desired final moisture content is 15%, ending dry matter content is 85% (100 minus 15).
3. Multiply weight of wet grain by initial percent of dry matter; then divide by desired ending percent dry matter.

What causes splits in soybeans?

Improper rotor speed can result in excessive cracked or split soybeans in the sample. If this occurs, increase rotor speed until you see a cracked soybean appear in the sample. Then, slowdown by 10 RPM.

Do soy products go bad?

Products often stay fresh after 10 days, but it cannot be guaranteed (this is when the look and smell test comes in handy). The soy milk sold on shelves is similar to canned food in that it lasts a long period of time in your cupboard if it’s not opened. It can have expiry dates that last as long as 8 months.

Do soybeans seeds go bad?

“Soybeans will degrade much more rapidly, and it’s hard to store them for even just a year and have confidence that you will get good germination,” Ehler said. In fact, an Iowa State study found that soybean seed germination rates dropped below 20% after 16 months in a warehouse with no climate control.

What percent moisture is soybeans dry?

By definition, a standard bushel of soybeans weighs 60 pounds and is 13% moisture. Since 13% of the weight is water, only 87% is dry matter. The dry matter in a standard bushel is 52.2 lb (60 lb x 0.87) and the remaining 7.8 lb is water.

How much does a bushel of corn weigh at 14% moisture?

These are: corn (shelled) – 56 lbs. at 15.5% moisture, soybean – 60 lbs. at 13% moisture, oats – 32 lbs. at 14% moisture, wheat – 60 lbs.

How do you test corn moisture?

The most accurate method of determining grain moisture content is the standard scale and oven-based test which uses published standardized procedures to dry a sample in a laboratory oven. The moisture content is then calculated using an equation based on the weight lost during the oven drying.

How long after rain can you harvest soybeans?

With good drying weather, the beans should be ready to harvest four to five days after this. They should be at 13-14% moisture, but with careful combining, beans of higher moisture can be successfully harvested.

How do you harvest soybeans?

Soybean Harvest Tips Begin harvesting at 14% moisture. What appears to be wet from the road may be dry enough to harvest. Try harvesting when some of the leaves are still dry on the plant; the beans may be drier than you think. Soybeans are fully mature when 95% of the pods are at their mature tan color.
