FUKUSHIMA REBORN
Near the Fukushima disaster site, scientists and citizens work tirelessly to clean radiation from affected farmland soils.
METER SUPPORTS TAHMO
Trans-African Hydro-Meteorological Observatory (TAHMO) is a not-for-profit organization. TAHMO makes high-quality data freely available to governments, scientists and farmers in real time.
Soil moisture sensing—reinvented
The TEROS 12 goes beyond merely optimizing the reading to optimize the accuracy of the whole data set. It combines consistent, flawless installation, minimal sensor-to-sensor variability, and a large volume of influence to deliver performance, accuracy, and reliability at a price you can afford.
DISCOVER ALL ATMOS INSTRUMENTS
As world experts in soil-plant-atmosphere measurements, we developed the ATMOS weather and climate product line without any moving parts to keep it reliable and simple.
Only using partial curves? Get what you’ve been missing.
Now, generate complete high-resolution moisture release curves across the entire moisture range. It’s easy. Start with the WP4C, then just add HYPROP. Mix in data from the KSAT to add a full hydraulic conductivity curve.
The researcher’s complete guide to soil moisture
Everything you need to know about measuring soil moisture—all in one place.
Soil moisture measurement methods—compared
A comparison of the most common soil moisture sensing methods, the pros and cons of each, and in what type of situation each method might be useful.
The researcher’s complete guide to water potential
Everything you need to know about measuring water potential—what it is, why you need it, how to measure it, method comparisons. Plus see it in action using soil moisture release curves.
Soil moisture release curves—What they are. Why you need them. How to use them.
Soil moisture release curves are powerful tools used to predict plant water uptake, deep drainage, runoff, and more.
Soil Moisture 102:
Water Content Methods–Demystified
Dr. Colin Campbell compares measurement theory, the pros and cons of each method, and why modern sensing is about more than just the sensor.
Soil Moisture 301—Hydraulic Conductivity
Why you need it. How to measure it.
If you want to predict how water will move within your soil system, you need to understand hydraulic conductivity because it governs water flow.
