What is saline agriculture?

In this report, ‘saline agriculture’ is defined as the cultivation of both halophytes and traditional freshwater crops (such as potatoes and carrots) under more saline soil and water conditions.


Is salt water good for plants?

Salt affects a plant’s normal growth process and prevents it from getting essential nutrients and hydration. Saltwater damage in plants interferes with photosynthesis and eventually results in a plant dying. Spraying salt water on leaves can even lead to leaf burn.


Which salt is suitable for agriculture?

Sodium is a nutrient for a number of crops, particularly those with ‘maritime’ origins as their ancestors grew near the sea. The most high profile of these crops is sugar beet. Sodium is also recommended for use on crops such as asparagus, celery and carrots.


How does salt water work?

Salt water is pumped into a pipe that runs along the top of the wind-facing wall. The wall is covered with a sort of ‘blanket’ that draws the water down; when the wind blows through, the water evaporates, cooling the air. (It works the same way as hanging a damp towel in your house on a hot day ).

Does Jordan have seawater?

Jordan also has seawater… sort of. Though mostly landlocked, with its access to the Mediterranean separated by Israel and Lebanon, 26km of the country borders the Red Sea. That isn’t much coastline – but with the approach being taken by the Sahara Forest Project, that may be all it needs.


How does seawater help agriculture?

It turns out, the seawater can be beneficial for agriculture through many things. For some sources, the seawater must enter into the spaces distillation. After that, by using sun’s rays, it helps the seawater to evaporate and changed into dew points. Those dew point will flow into the freshwater shelter hole and the water will use …


Why do farmers use seawater?

Most of the garden of agriculture uses sea water to lift the sugar levels of fruits and it really works for the plant too. The farmer’s garden also frequently uses seawater to feed their corps because they believed that seawater really helps their plants. Not only the plants, but seawater also works to nourish the fruits, …


Why do plants need sea water?

Seawater can help the plants to take nutrient elements and absorb use of carbon in the ocean dioxide from the air, also to take the sun’s rays. This condition will make your plants more fertile and prevent them from the virus that harms them. So, seawater really helps the plant to grow and to take their own ‘food’.


Why is sea water important for plants?

Because of sea water will irrigate and flow to every ground then help the plant to grow. Seawater – with its salt content – can create a more fertile soil. When the soil is fertile, it will affect the plants which are good also for the human to take the benefits from it. Seawater really helps the soil for planting.


How to prevent soil from drought?

How is seawater used in farming?

In Australia, as proposed by Seawater Greenhouse Foundation, seawater are evaporated using sunlight in “green-house” to produce freshwater, which are used to support farming crops such as potatoes, cucumbers and fruits. The salts, by products of the process, are collected and processed into gourmet salts. It is estimated that the seawater green-house has a reduced fixed cost of 10-15% less and operational cost of 10-25% less than the conventional green-house while returns 15-35% more. Seawater Greenhouse Foundation who has designed the existing technology has proposed a pilot project to build an experimental station in Sahara, which will be followed by a large-scaled project.


How is seawater created in a greenhouse?

Diagram of a “seawater greenhouse”: the humid conditions inside the greenhouse is created by the evaporation of seawater at the front of the building at the “seawater surface” through porous cardboard. Some evaporated seawater is condensed as freshwater to irrigate the crops or stored away for future usage.


How is seawater heated?

The air is warmed up and humidified since this seawater has been heated by the sun in a network of pipes above the growing area. The humidified air then meets a series of vertical pipes through which cool seawater passes and condense water droplets that run down to the base to be collected.
