Frequently Asked Questions: Soil Science

What are the key parameters that are to be measured before hand, like the evapotranspiratio, in order to determine the amount of water that is to be used for irrigation?
A weather station typically measures solar radiation, temperature, wind
speed, and relative humidity. These parameters are then used to
calculate evapotranspiration, which is then used as a starting point in
the process of fine tuning your irrigation to site specific conditions
which can vary widely, such as soil type.
What is the conversion for evapotranspiration using wheat instead of turf grass? Also, is there anything for bare soil?
Here is a link to a website that goes over crop coefficients for various
crop types, and also talks about estimating evaporation from bare soil.

Can I replace only the plastic, three-prong cup part of the anemometer for my weather station?
Yes, Here is a link to the manual for the Wind Sentry, wind speed and
direction sensor, which goes over the cup replacement procedure.

For price and more info on other models, please call.
Do you offer a low end weather station that will interact or initiate a rain shut command for the Legacy Genesis 3 Central Control software? (golf application)
We manufacture a weather station for Hunter that they have integrated with some of their irrigation software and control packages. For
details on rain shutoff capabilities, and irrigation control specific to
Hunter systems please call your Hunter distributor.
How can I use a datalogger to measure solar radiation?
We carry several solar radiation sensors for varying applications.

The manuals specific to each sensor will tell you which loggers are
compatible with each sensor and contain example programs and wiring
diagrams.
