Soil monitoring creates a better understanding

From crop management to environmental research on climate change impacts, soil monitoring plays a crucial role in improving farming practices, protecting water resources, and achieving sustainability for tomorrow. Field-proven HOBO data loggers track multiple soil parameters with Smart Sensors and HOBOnet remote monitoring wireless sensors for precise soil conditions.

Frequently Asked Questions

The HOBOnet T11/T12 sensors not only measure soil moisture (volumetric water content) with better accuracy and precision, but also provide soil temperature measurements. Designed to withstand harsh environmental conditions, these durable sensors last up to 10 years, so you can leave them in the field for extended periods of time. Sharpened stainless-steel probes make installation easy, even in hard soil, and an increased volume of influence provides better results and a more accurate view of soil moisture. Its technology is backed by over 20 years of soil-moisture research and features a trademark 70MHz frequency capacitance technology, minimizing salinity and textural effects

Yes, using the RXW-T12-xxx

HOBOnet supports the following soil measurements: temperature, moisture, electrical conductivity, and water potential

Soil can take up to 6 months to return to its natural state once disturbed. Soils in wet climates return faster than dry ones

Tension or soil water potential is a measure of the tension or stress of a plant required to pull water from soil. Different soil types retain water differently, which means that for the same amount or percentage of water, plants must exert different amounts of tension to absorb that water.

Field saturation is the threshold at which point all empty spaces between soil particles are filled with water.

Field capacity is the threshold of when water in larger pores has been drained away by the force of gravity. Most agricultutal soils reach field capacity 1 to 3 days after an irrigation or rain event.

The Permanent Wilting Point is the threshold when it becomes impossible for plants to extract water at a rate fast enough to keep up with their water demand.
