Saltwater intrusion from sea level rise and tidal flooding is increasing soil salinity risks in coastal farm fields (Figure 1). Soil salinity is related to the presence of soluble salts and cations ...

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 ...

A team of researchers has developed an approach that maps the soil salt content around the world with an exceptional detail of 10 meters. This advance tackles the pressing need for accurate ...

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of ...

Researchers have identified naturally occurring soil bacteria that could help farmers protect crops from increasing soil ...

Remote sensing offers a powerful toolkit for detecting, mapping and monitoring soil salinity at scales ranging from local to global. By exploiting spectral reflectance across optical, thermal infrared ...

Salination causes harvests to fail across the globe. Plants die, or their growth is stunted. Researchers of Wageningen University & Research (WUR) have discovered that a local regulator protein ...

Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...

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 ...
