SUMMARY
The American Soybean Association and the US Soybean Export Council have supported a
survey of the quality of the US soybean crop since 1986. This survey is intended to provide
new crop quality data to aid international customers with their purchasing decisions.
2015 ACREAGE, YIELDS, AND TOTAL PRODUCTION
According to the November 2015 United States Department of Agriculture, National
Agricultural Statistics Service (USDA‐NASS) Crop Production report, area harvested and yields
will change only slightly from 2014. The total US soybean harvested area decreased by 1% to
33.4 million hectares (Table 1). Average yield remained at 3.2 MT per hectare. Together,
2015 yield and area harvested will result in a US crop that is about 0.65% higher than the
record 2014 crop. The USDA expects the US crop to be 108.5 million MT.
QUALITY OF THE 2015 US SOYBEAN CROP
Sample kits were mailed to 5,094 producers that were selected based on total land devoted
to soybean production in each state, so that response distribution would closely match
projected soybean production. By 4 December, 2015, 1,789 samples were received. These
were analyzed for protein, oil, and amino acid concentration by near‐infrared spectroscopy
(NIRS) using a Perten DA7250 diode array instrument (Huddinge, Sweden) equipped with
calibration equations developed by the University of Minnesota in cooperation with Perten.
Regional and national average quality values were determined by computing weighted
averages using state and regional soybean production data, so that average values best
represent the crop as a whole. Results are in Tables 2a through 5.
INTERPRETATION OF PROTEIN AND OIL RESULTS
Overall, the 2015 US soybean crop quality, as measured by protein and oil concentration,
increased significantly from that of the excellent 2014 crop. Although protein concentrations
were similar to those in 2014, oil concentration was higher in every region of the US. Due to
a unique set of weather conditions, there tended to be less variation in both protein and oil
QUALITY REPORT: 2015

than is evident in most years. Compared with the long‐term average, 2015 US soybeans were
0.8 of a point lower in protein, but 1.0 percentage points higher in oil.
Average US soybean protein concentration was only 0.1 percentage points lower in 2015, at
34.3%; however, average US oil concentration was 1.1 percentage points higher at 19.7%
when compared with 2014 (Table 5). This oil level represents a record high for US soybeans,
and will allow soybean processors to simultaneously achieve both high soybean oil yields and
good protein concentrations in soybean meal produced.
As is noted in most years, Western Corn Belt states showed lower protein concentrations than
the US crop as a whole (Table 2a) but differences were much smaller in 2015; Western Corn
Belt oil was near the US average. Soybeans grown in the Eastern Corn Belt were lower in
protein than usual, and their protein concentration was very similar to the national average.
Nearly every state in the Eastern Corn Belt region produced much lower protein soybeans
than in 2014. The Midsouth, Southeast, and East Coast had higher protein concentrations
than the US average.
Regional oil levels increased over 2014 levels from 0.6 percentage points in the Midsouth to
1.5 percentage points in the East Coast region. In the Western Corn Belt region, where
proteins were similar to 2014, average oil values increased by 1.1 percentage points. Oil
levels increased by 1.3 points (a 7% increase) in the Eastern Corn Belt, covering some of the
losses from lower protein values in this region. A dramatic example of this is Wisconsin,
where oil increased by 1.7 points while protein dropped by 0.6 points. Another extreme
example is North Dakota where protein increased by 0.3 points and oil increased by 1.5. This
change will make these normally protein‐challenged soybeans quite valuable to processors.
Warm and dry late‐season conditions resulted in a drier soybean crop than in 2014. In fact,
average moisture levels of incoming samples were lower in every region compared with last
QUALITY REPORT: 2015

year (Table 2b). The average moisture of samples received in 2015 was 11.6%, down 0.8
percentage points from 2014. Western Corn Belt and Midsouth soybeans tended to be the
driest of all of the regions, so protein and oil levels on an as‐is basis tended to increase the
most in those regions. For Western Corn Belt soybeans, an as‐is composition of 34.8%
protein and 20.0% oil is quite extraordinary for a region that generally produces low protein
soybeans.
INTERPRETATION OF SEED SIZE AND FOREIGN MATERIAL RESULTS
While seed size may not be important for most commodity soybean purchasers, seed size
does provide some insight into the environmental conditions present during the production
season. Seed size can also be correlated with changes in protein and oil concentration due to
these same environmental conditions. In general, environmental stresses such as drought in
the early seed‐filling period (late July and early August) tend to reduce the number of seeds
on individual plants; if conditions return to normal; these remaining seeds can expand,
resulting in larger than average seed size. Alternatively, stresses at the end of the seed‐filling
period (late August through September) reduce the energy available for each seed and seed
size may be smaller than average. In 2015, seed size was similar to that in 2014, with the
average seed size decreasing slightly from 16.0 grams per 100 seeds in 2014 to 15.8 in 2015
(Table 3). As is normally noted when there are hot conditions during the latter part of the
growing season, seed size tended to be smallest in the Midsouth and Southeast regions.
Although the Eastern Corn Belt tends to produce much larger seeds, on average, 2015 seed
size there was only slightly above average. Seed size decreased by more than 7% in Indiana
where a late season drought restricted seed growth and ultimately yields.
Foreign material (FM) found in 2015 US samples was, on average, very low at 0.2%, with
regional averages ranging from 0.1 to 0.4%. Of the 1,789 samples, 97.6% of them (1,747
samples) had FM values below 1%, 1.6% (28 samples) had 1‐2% FM, and only 0.8% of them
(14 samples) had >2% FM.

AMINO ACIDS
Amino acids are the “building block” organic compounds linked in various combinations to
form unique proteins. In human diets, amino acids are supplied by the variety of plant and
animal proteins ingested. In animal feed, amino acids come from feed proteins such as
soybean meal, or from synthetic amino acid supplements. Soybean meal is the major feed
protein source in poultry, swine, and cultured fish diets because of its high nutritional quality
including its balanced amino acid profile. Optimal animal performance occurs when the feed
protein contains an ideal amount and proportion of all essential amino acids (those amino
acids which cannot be formed by animals) – this is an “ideal protein”.
Preferably, the use of a high quality protein source with an excellent balance of amino acids
to meet the most limiting amino acid requirements at a lower protein concentration is a far
more efficient option than using a lower quality protein source. In a comparison of soybean
meal from US and other origins, US soybean meal had lower protein content than Brazilian
soybean meal, but better quality of protein – higher concentrations of essential amino acids
(Park and Hurburgh, 2002; Thakur and Hurburgh, 2007; Bootwalla, 2009). In whole soybeans,
lower crude protein beans have a higher proportion of the five most critical essential amino
acids (lysine, cysteine, methionine, threonine, and tryptophan), indicating that meal made
from those soybeans will likely be of higher feed quality for a given feed ration than meal
made from higher crude protein soybeans (Thakur and Hurburgh, 2007; Medic et al., 2014;
Naeve unpublished data).
The 2015 amino acid results were similar to those found in 2014, in that there was little
regional variation for lysine (expressed as a percent of the 18 primary amino acids) (Table 4).
Additionally, in 2015 there was little regional variation for the five most limiting amino acids
(cysteine, lysine, methionine, threonine, and tryptophan), with the WCB, ECB, MDS, and SE at
14.6 and the EC at 14.5. Regional differences alone do not fully explain amino acid
concentration differences in the samples; when we evaluated the samples based on protein
QUALITY REPORT: 2015

level rather than region, we found that the protein in lower protein samples is more
concentrated in the five critical amino acids than is the protein in higher protein samples.
Thus, protein concentration differences may account for amino acid concentration differences
across regions, rather than region per se.
WEATHER AND CROP SUMMARY
Plan ng: In late April and early May, northern parts of the US Midwest were dry and warm,
allowing growers to complete fieldwork and planting earlier than average; soybean planting
in Minnesota and Wisconsin was nearly 20% ahead of the 5‐year average for those states.
However, in late May, heavy rainfall moved into the upper Midwest (Weather Figure 1), and in
June lingered in parts of the ECB, WCB, EC, and the MDS, leading to flooding and delays in
fieldwork in parts of those regions. The contiguous US experienced its wettest May on record
(Weather Figure 1). By June 7, 79% of the nation's soybean crop was planted, 7% behind
2014, likely due to the excess rainfall.
Mid‐Season: July was cooler and wetter than average for many soybean‐growing states,
particularly in the middle of the US soybean‐growing region; the Midwest region had its 8th
wettest July on record. August was cooler than average, and the excessive rainfall ended, but
conditions then became much drier than normal, especially in the ECB and EC, further
stressing plants that had earlier been flooded.
Harvest: September temperatures for the Midwest were among the warmest on record;
those higher than average September temperatures, combined with dry conditions in most
areas west of the Mississippi River (Weather Figure 1), led to rapid harvest progress. By
October 25, growers harvested 87% of the US soybean crop, 19% points more than the same
time period in 2014.

Overall, weather during the 2015 growing season was generally wetter than normal in some
large soybean‐producing states, then turned drier and warmer than average in September,
though some states did experience near ideal growing conditions.
