Soil moisture is the water that is held in the spaces between soil particles, generally in the upper 10 cm of soil. Although soil moisture is just a fraction of the total water mass in the water cycle, this small amount of water plays a critical role in evaporation and plant transpiration proces
In this activity, students investigate three different soil samples with varying moisture content. They use a soil moisture probe to determine the percentage (by volume) of water in each of the soil samples.
Test your knowledge of soil moisture and its effect on global populations. Soil moisture is the amount of water contained in the soil.
In 2015, Ethiopia endured its worst drought in decades. While there is some indication that this April has been drier than normal in some areas, the intensity of the drought this year will not be clear until later in 2016.

NASA SMAP Data Provide Insights for Weather, Agriculture, Climate
The Soil Moisture Active Passive mission (SMAP) was launched in 2015 as the first NASA satellite dedicated to measuring the water content of soils. The satellite uses a radiometer to measure soil moisture in the top 5 centimeters of the ground.
