Lab and field instruments used together can provide researchers a symphony of information and can be used as powerful tools in understanding data and predicting a soil’s behavior over time.
How to set SDI-12 addresses in METER digital sensors using Campbell Scientific data loggers and LoggerNet.
Among the thousands of peer-reviewed publications using METER soil sensors, no type emerges as the favorite. Thus sensor choice should be based on your needs and application. Use these considerations to help identify the perfect sensor for your research.
To maximize crop yield, it is important to maintain soil water content somewhere between field capacity and permanent wilting point.
Accurate, inexpensive soil moisture sensors make soil VWC a justifiably popular measurement, but is it the right measurement for your application?
The number of soil moisture sensors can make the difference between proving a hypothesis or missing it entirely. How many sensors will complete a soil moisture picture?
Though water potential is a better indicator of plant available water than water content, in most situations, it’s useful to combine the data from both sensors.
Installing soil moisture sensors will always involve some digging. How do you accurately sample the profile while disturbing the soil as little as possible? Consider the pros and cons of five different profile sampling strategies.
Employing a durable wire-splicing technique is very important when considering the harsh environments a connection must withstand.
Measuring electrical conductivity can prevent saline soil, which ceases to support agricultural production.
Protect your soil moisture sensors from lightning surge.
Irrigated land accounts for 40% of our food supply, and salts impact yields on about one-fifth of those acres.
In this video, application and support specialist, Chris Chambers, demonstrates his troubleshooting workflow and fixes for common problems.
The basis for compost moisture reporting is not the same as for soil water content.
Irrigating with soil sensors increases plant quality, prevents stress, and reduces water use and leaching without expensive recycling irrigation systems or large ponds.
When considering which soil water content sensor will work best for any application, it’s easy to overlook the obvious question: what is being measured? Time domain reflectometry (TDR) vs. capacitance is the right question for a researcher who …
The results of tests conducted to quantify the measurement volume of METER’s VWC sensors.
In many natural and engineered soils, the output of ECH2O soil moisture sensors are sensitive to variations in the soil temperature. The temperature sensitivity is not caused by the ECH2O sensors themselves, but rather the electrical …
SDI-12 is a communications protocol that comes with a myriad of possibilities for research. Understand the basics of setting up a system, SDI-12 pros and cons, and how to fix common problems.
Accuracy increases to ± 1-2% for all soils and soilless substrates with soil-specific calibration. Here’s a step by step guide to performing your own calibrations.
