2015 AGRICULTURAL CHEMICAL USE SURVEY

About the Survey

The 2015 Agricultural Chemical Use Survey of soybean producers collected
data about fertilizer and pesticide use as well as pest management practices
in growing soybeans. NASS conducted the survey in 19 states that accounted
for 96 percent of the 82.7 million acres planted to soybeans in the United
States in 2015: Arkansas, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana,
Michigan, Minnesota, Mississippi, Missouri, Nebraska, North Carolina, North
Dakota, Ohio, South Dakota, Tennessee, Virginia, and Wisconsin (Fig. 1).

AGRICULTURAL
CHEMICAL USE

The Agricultural Chemical Use
Program of USDA’s National
Agricultural Statistics Service (NASS)
is the federal government’s official
source of statistics about on-farm and
post-harvest commercial fertilizer and
pesticide use and pest management
practices. NASS conducts field crop
agricultural chemical use surveys
as part of the Agricultural Resource
Management Survey.
NASS conducted the soybean
chemical use survey in fall 2015.

Data are for the 2015
crop year, the oneyear period beginning
after the 2014 harvest
and ending after the
2015 harvest.

Fertilizer Use
Fertilizer refers to a soil-enriching input that contains one or more plant
nutrients, primarily nitrogen (N), phosphate (P2O5), and potash (K2O). For the
2015 crop year, farmers applied nitrogen to 28 percent of planted acres, at an
average rate of 17 pounds per acre, for a total of 382.3 million pounds. They
applied phosphate to 39 percent of soybean planted acres and potash to
38 percent of

acres. (Table 1)

Pesticide Use
The pesticide active ingredients used on soybeans are
classified in this report as herbicides (targeting weeds),
insecticides (targeting insects), fungicides (targeting
fungal disease), and other chemicals (targeting all
other pests and other materials, including extraneous
crop foliage). Herbicides were used most extensively,
applied to 96 percent of planted acres. Insecticides and
fungicides were applied to 22 and 11 percent of planted
acres, respectively. (Fig. 2)
Among herbicides, two different forms of glyphosate
were the most widely applied active ingredients (Table
2). They were also the top herbicides in a similar survey
in 2012.

•	 Prevention practices involve actions to keep a pest
population from infesting a crop or field.
•	 Avoidance practices use cultural measures to
mitigate or eliminate detrimental effects of pests.
•	 Monitoring practices observe or detect pests
through sampling, counting, or other forms of
scouting.
•	 Suppression practices involve controlling or reducing
existing pest populations to mitigate crop damage.
The most widely used pest prevention practice in
growing soybeans was no-till or minimum till, used on
74 percent of planted acres. The top avoidance practice
was rotating crops (90 percent). Scouting for weeds was
the most widely used monitoring practice (94 percent).

Pest Management Practices
The survey asked growers to report on the practices
they used to manage pests, including weeds, insects,
and diseases. Soybean growers reported practices in
four categories: prevention, avoidance, monitoring, and
suppression (PAMS).
