Suelo salino (afectado por la sal)
Los agricultores y cultivadores de las regiones áridas y semiáridas del mundo enfrentan dos problemas asociados pero separados, que limitan los cultivos que pueden producir y su rendimiento. El problema subyacente es la falta de la lluvia necesaria para cultivar plantas. El segundo es la acumulación de sales en la zona radicular. Los dos están relacionados entre sí, pero no necesariamente ocurren al mismo tiempo.
Las plantas necesitan una cierta cantidad de sales solubles, pero el exceso de sales en la zona radicular reduce el crecimiento de la planta al alterar la absorción de agua. Cuando el contenido de sal del agua del suelo es mayor que el del agua dentro de las células de la planta, las raíces de la planta no pueden absorber el agua del suelo e incluso pueden perder agua en el suelo. El exceso de sales en el suelo también puede provocar toxicidades o desequilibrios específicos de iones. En algunos casos, la cura para estos problemas es simplemente mejorar el drenaje. Sin embargo, los problemas de salinidad suelen ser más complejos y requieren un manejo adecuado del suelo, así como el uso de cultivos tolerantes a la sal.

Recurso clave 1/1/1990 The agricultural use of saline water or soils can benefit many developing countries. Salt-tolerant plants can utilize land and water unsuitable for salt-sensitive crops (glycophytes) for the economic production of food, fodder, fuel, and other products. Halophytes (plants that grow in soils or...

In recent years, salinity has become the most important issue in fields, gardens and greenhouses as well. This, of course, has forced us to control saline areas, and therefore, many control mechanisms that have been put forward. Many of them (genetics, biochemical and physical) have not brought...

Abstract, 2018, Sustainability Saline irrigation water can lead to salt buildup and reduced crop yields. Halophytic plants are known to accumulate excess salts in tissues, removing them from the immediate environment. This two-phase experiment explored the feasibility of intercropping watermelon...
- Abstract, 2008, Soil & Water Research Soil and water salinization are affecting an increasing number of countries in the world, especially in arid and semi-arid regions, and cause sensible reductions of agricultural land extension and of crop yields. Consociation with halophytic plants is a...

This handbook is written for farmers, and agricultural extension officers in government and nongovernment organisations. Our aim is to provide a simple accessible account of saline agricultural practices for irrigated land in Pakistan.
- Abstract, 2017, Turkish Journal of Agriculture and Forestry Salt-induced land degradation has gradually increased in several major irrigation schemes within arid and semiarid regions. To maximize crop productivity under saline conditions, either salt tolerance crops should be cultivated or areas...

Abstract, Annals of Botany, 2014 Recruiting wild halophytes with economic potential was suggested several decades ago as a way to reduce the damage caused by salinization of soil and water. A range of cultivation systems for the utilization of halophytes have been developed, for the production of...
