AGRICULTURE AND SOIL MONITORING
Measurement Instruments for Agriculture and Soil Applications
R E L I A B L E
Campbell Scientific provides professional- and research-grade measurement systems for many applications within agriculture and soil
moisture markets. Our systems measure both soil water and environmental parameters related to evapotranspiration, plant growth and
development, and disease modeling. Multiple sensors can be networked in hard-wired or wireless systems, while portable, hand-held
MAJOR SYSTEMS
systems can make point measurements to verify irrigation scheduling
or to perform site surveys.
Campbell products are key to agricultural research, irrigation and
planting scheduling, harvesting, watershed studies, frost prediction,
and timing for pesticide and fertilizer applications.

Dataloggers
Sensors
All of our measurement systems are based around a programmable datalogger (typically a CR800, CR1000 or CR3000) that
measures the sensors, then processes, stores, and transmits the
data. Our low-power dataloggers have wide operating temperature ranges, programmable execution intervals, onboard instructions, and ample input
channels for commonly
used sensors. Our
dataloggers interface
directly to most sensors,
eliminating external
signal conditioning.
Data are typically output in the units of your choice (e.g., wind
speed in mph, knots, m/s). Measurement rates and data recording intervals are independently programmable, allowing calculation of 15-minute, hourly, and daily data values from 1-minute or
1-second measurements. Atypical events can trigger alarms and
cause additional data to be recorded. Channel capacity can be
expanded using multiplexers.
Almost any sensor can be measured by our dataloggers, allowing
stations to be customized for each site. Typical sensors used on
our stations include, but are not limited to: wind speed, wind direction, solar radiation, air and soil temperature, relative humidity,
precipitation, soil moisture, barometric pressure, and leaf wetness.
Data Retrieval
We offer multiple communications options for data retrieval,
which can be mixed within the same network. Telecommunications options include short-haul, telephone (land line, voice-synthesized, cellular), radio frequency, multidrop, and satellite. On-site
options include storage module and laptop computer.
Software
Our PC-based support software simplifies the entire monitoring
process, from programming to data retrieval to data display and
analysis. Our software automatically manages data retrieval from
networks or single stations. Robust error-checking ensures data
integrity. We can even help you post your data to the Internet.
Agriculture and Soil Monitoring Case Studies
Our agriculture and soil monitoring systems have helped a variety of organizations reach their goals. The following are just a
few of these:
In California, an automated system for alfalfa flood irrigation
research included three water sensors buried and spaced in a row
(following the direction of the water flow) toward the lower end of
a long bay, known as a check. As the water sheet proceeded down
the field, a Campbell Scientific CR3000 Micrologger® recorded the
arrival of water at each sensor, and used a cellular modem to transmit that information to the irrigators.

In Colombia, Campbell gear is used to study greenhouse conditions for the purpose of battling fungus growth on roses. To set
up the study, researchers built two measurement stations. The stations, powered by solar panels, included several LWS Leaf Wetness
Sensors and SI-111 Infrared Radiometers positioned at a variety
of locations among the plants. These sensors were connected to
Campbell CR1000 dataloggers via our AM16/32 multiplexers.

Forty-nine Campbell Scientific weather stations make up North
Dakota’s Agricultural Weather Network (NDAWN). Data from the
network is used for irrigation scheduling, pesticide application
scheduling, and various research projects. The standard stations
monitor air temperature, relative humidity, wind speed and direction, solar radiation, rainfall, and soil temperature.

The West Texas Mesonet (WTM) project was initiated by Texas
Tech University in 1999 to provide free real-time weather and
agricultural information for residents of the South Plains region
of western Texas. The WTM uses Campbell Scientific dataloggers, towers, enclosures, communication devices, and sensors
that measure wind, air temperature and humidity, sunlight, soil
temperature and water content at multiple depths, precipitation,
and barometric pressure.

Data gathered from the Colombian study on fungus growth allow
rose farmers to curtail fungus growth while being less dependent on
pesticides. The study’s LWS leaf wetness sensors are shown above.
