Enhancements in Meteorological and Hydrological Models Using Soil Moisture Data

It has long been known that there is a strong relationship between soil water content and the health and yield of crops. But only in the past few decades has science quantified the specifics of these relationships. This research has expanded to develop a relationship between soil moisture levels and the impact on meteorological and hydrological models and forecasts.

Introduction to Soil Surveys for Agronomic Use

The USDA's Introduction to Soil Surveys for Agronomic Use, entitled "From the Surface Down", is an introduction to soil types, horizons, and how they are measured. The intent of this publication is to increase user understanding of soils and acquaint them with the contents of a soil survey and supplemental interpretations that are important to agronomic programs.

NRCS Urban Soil Primer

The Urban Soil Primer is intended to give planning officials and people who live in urban areas an introduction to soils. It provides information important in planning and managing land resources in a manner that helps to prevent or mitigate problems associated with sedimentation, contamination, runoff, and structural failure. In non-technical language, this publication describes the basic processes and functions common to all soils.

Evaluation of the Stevens HydraProbe Temperature Measurements from -30 to +40 Degrees Celsius

Soil temperature data down to -30° Celsius is becoming more and more relevant to climate studies. While environmental issues fuel the development and the widespread use of sophisticated environmental models, reliable input data is becoming essential for researchers and modelers. The soil temperature data collected by the HydraProbe can be used in climate studies in arctic regions, regional energy budget calculations, drought forecasting and heat fluxes. It is the intent of Stevens Water Monitoring Systems to provide the scientific community a reliable and cost-effective soil temperature sensor to suit the needs of environmental researchers.

The Stevens HydraProbe Inorganic Soil Calibrations

The Stevens HydraProbe can be calibrated to accommodate almost any inorganic soil regardless of clay content or organic matter. While the default calibrations are suitable for most soils, other published calibrations can be used to obtain a higher level of accuracy if specific textural information about the soil is available.

Soil Moisture Applications and Practices Using the HydraProbe Soil Moisture Sensor

Over the past ten years, environmental monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related soil hydrological processes. Monitoring soil moisture conditions provides important information for the protection and in the understanding of local and regional water resources. The Stevens HydraProbe soil sensor is the most advanced soil sensor commercially available and described below are application examples where the HydraProbe has been used to gather data.
