A focus at the European Space Agency's Living Planet Symposium is on the innovative Soil Moisture and Ocean Salinity (SMOS) mission, which recently became operational. Early results are proving very ...

Soils affected by salts can be described in two ways: by salinity classification or by potential crop response (Figure 1). Salinity classifications are based on the total accumulation of salts in the ...

Notes: the subfigure shows an example of acidic soil areas defined by the World Reference Base for Soil Resources; the scatterplot shows the salt content of soil samples in five climate regions. A ...

ESA's next Earth Explorer, SMOS, has just passed the all-important Flight Acceptance Review, signifying that all the elements that make up the mission are in place for launch later this year. The ...

Many nutrients in soil exist as salts, soluble and available for plant uptake. But when salts accumulate in excess, crop growth can decline. With more frequent surface flooding in coastal fields and ...

One-third of the Earth's land surface is already degraded. The UN estimates that more than 2.6 billion people are harmed by land degradation, with countries losing up to US$10.6 trillion (£7.8 ...

Measuring soil moisture with time-domain reflectometry (TDR) sensors can aid in turfgrass water conservation efforts and help improve playing conditions. However, information is lacking on the ...
