Saline (salt-affected) Agriculture
Farmers and gardeners in semi-arid and arid regions of the world face two associated but separate problems, which limit the crops they can grow and the yield of these crops. The underlying problem is lack of rainfall needed for growing plants. The second is accumulation of salts in the root zone. The two are interrelated, but do not necessarily occur together.
Plants need a certain amount of soluble salts, but excess salts in the root zone reduces plant growth by altering water uptake. When the salt content of soil water is greater than that of the water inside the plant cells, the plant roots cannot absorb the soil water. They may even lose water to the soil. Excess soil salts can also cause ion-specific toxicities or imbalances. In some cases, the cure for these problems is to simply improve drainage. However, salinity problems are often more complex and require proper soil management as well as use of salt tolerant crops.

Tài Nguyên Chính 01-01-1990 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...

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...
