Pressure Membrane Apparatus - User Manual
The 0803 Pressure membrane apparatus can be used for the determination of pF values between 3.0 and 4.2. When lower pF values need to be applied to samples, then the 0801 Sandbox (pF 0 – pF 2), or the 0802 Sand/ Kaolin box (pF 2.0 - pF 2.7), can be used. This manual describes how to prepare the equipment for measurements, measure soil water content, and calculate and interpret the retention ...

Watermark - Soil Moisture Meter - Installation and Operating Instructions Manual
The soil acts as a reservoir to store water between irrigations, or rainfall events, so that it is available to the crop or plants as needed for healthy growth. The purpose of using sensors to measure soil water is to give you a better understanding of how fast water is being depleted in the different areas of your field, so you can better schedule your irrigations and correctly evaluate the ...

Hyprop - Model 2 - Soil Moisture Release Curves - Datasheet
Measuring soil water potential to create a moisture release curve has always been tricky. Even if you’re an expert at traditional methods, these measurements require a tremendous amount of work. Plus, you still face limitations—like a lack of data points— that affect the final result. Some methods take several months just to complete a partial curve. And if that wasn’t ...

Product Catalog
Soil Moisture Sensor is your best tool to measure soil water content at multiple depths. Water and nutrients are used most efficiently when an irrigation event applies only the amount of water the crop needs and the soil can hold. When you utilize these sensors at different depths, you can be much more precise with duration and amount of irrigation water to apply. To know the saturation rate at ...

Soil Water Potential Sensors - Brochure
Water potential describes the force that drives water movement. It is the most fundamental and essential measurement in soil physics. A water potential sensor is a solid-state electrical resistance sensing device that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using a water potential Sensor. The ...
