Specialty Crop Block Grant Program boosts automation

U.S. specialty crop producers face
a variety of challenges that require a
diverse set of solutions. From labor
shortages and rising production
costs that threatened the health of
Florida's strawberry industry to water
supply challenges that stymied North
Dakota's vegetable yields, the Specialty
Crop Block Grant Program (SCBGP)
has helped producers bring to life
innovative ideas in automation.
USDA's Agricultural Marketing
Service provides annual SCBGP
funding to State Departments of
Agriculture for projects that support
specialty crop growers, producers and
consumers. The projects can range
from outreach and education, training,
marketing or research to enhance the
specialty crop industry. Each state
determines priorities that will be most
impactful to the issues they are facing.
In the case of addressing labor
shortfalls in strawberry harvesting, the
Florida Department of Agriculture and
Consumer Services awarded funding
to the University of Central Florida
to develop a project that is currently
engineering a mechanical arm. This
gripper will mimic human hands and
fingers as it picks strawberries - without
damaging the fruit. The technology
aims to be universal for different
strawberry varieties. The project will
also evaluate the economic impact of
the gripper creation.
To date, the project team finalized
their design and manufactured two
prototypes. Both prototypes have gone
through laboratory and field tests, and
one has been integrated with a robotic
arm-like platform for harvesting. The
team will measure project success by the
number of strawberry varieties to which
the picking mechanism can be applied
and the number of harvesting platforms
that decide to adopt the technology.
In North Dakota, the State
Department of Agriculture distributed
SCBGP funds to North Dakota State
University to tackle water management
issues. The project's goal is to improve
fruit and vegetable yields by creating
a drip irrigation system that can
be automatically controlled by soil
moisture sensors. The project involves
conducting experiments to see how
different mulch types and amounts
impact weed control with the system.
They will then educate local growers on
the new drip irrigation technology.
To date, the team has designed, built
propagation trays with results
and implemented the drip irrigation
system and conducted comparisons
on tomato and watermelon yield and
quality. With its projected ability
to conserve water, improve soil
temperature and extend growing
seasons, the team sees this system as the
future of North Dakota specialty crops.
Automated production methods have
been a common thread in multiple
SCBGP projects. According to the
recent USDA Economic Research
Service report, Developing Automation
and Mechanization for Specialty
Crops: A Review of U.S. Department
of Agriculture Programs, $12.5
million in funding on automation
and mechanization projects has been
distributed in the SCBGP between
FY 2008-2018. As states and growers
identify specific needs in the specialty
crop industry, SCBGP welcomes

innovative ideas to help the industries
evolve and adapt.
