What agricultural practice helps manage salinity in soils?

Improving drainage and adopting salt-tolerant crops are effective agricultural practices for managing salinity in soils. High salinity levels in soil can hinder plant growth by affecting root development and water uptake. By improving drainage, farmers can help prevent the accumulation of salts in the root zone, which can be caused by waterlogged conditions or rising groundwater levels. This means that excess salts are more likely to be leached away from the soil profile, reducing salinity levels.

In addition, planting salt-tolerant crops can provide farmers with viable options for cultivation in saline environments. These crops have adapted to thrive in high salinity conditions, allowing for continued agricultural production even when soil salinity is a challenge. Together, these strategies can significantly mitigate the impacts of salinity, thus enhancing soil health and crop productivity.

The other options, while they may have benefits in various contexts, do not specifically address salinity management as directly as improving drainage and adopting salt-tolerant crops. Planting native crops might enhance biodiversity, but it doesn't inherently solve salinity problems. Using organic fertilizers can improve soil health but does not specifically target salinity issues. Implementing crop rotation may help distribute nutrients and reduce pest pressure, but it doesn't directly mitigate salinity.
