    China is developing a salt-resistant hybrid-rice strain that can prosper in saline-alkaline soil. China has one million square kilometers of saline-alkaline soil that is currently producing nothing. If the salt-resistant hybrid-rice is a success then China would have gained one million square kilometers of prime farmland.

    Chinese scientist working to increase rice yield | GBTimes

    "Plans to increase the yield of salt-resistant hybrid rice to 300 kilograms per mu (667 square metres) within three years were announced by China's so-called 'father of hybrid rice' Yuan Longping this week.
    ...
    He plans to increase the yield by using third generation hybrid-rice technology at a research centre in Qingdao, east China's Shandong Province.

    The salt-resistant rice, also called sea-rice, is resistant to pests, diseases, salt and alkali and does not need fertilizer.

    It is believed that using the new technology developed by Yuan's team, China's 1.5 billion 'mu' (one million square kilometres) of saline-alkaline soil could be transformed into fertile land."

    I think China's goal of converting currently one million square kilometers of useless saline-alkaline soil into productive farmland is the most efficient way to grow a huge amount of food.

    The GBTimes article states the following facts:

    China's 1 million square kilometers of saline-alkaline soil is equivalent to 1.5 billion "mu" (ie. 667 square meters) of land.

    China plans to increase the yield of salt-resistant hybrid rice to 300 kilograms per mu.

    1.5 billion mu x 300 kilograms rice/mu = 450 billion kilograms of rice annually from saline-alkaline soil

    To match this level of incredible food output, China would have to massively irrigate desert land in Inner Mongolia or Xinjiang Province. It will take many years to build a complex of nuclear power plants to desalinate water and transfer it via huge pipes for hundreds/thousands of miles from Bohai Bay to Inner Mongolia or Xinjiang.

    To achieve a significant food surplus, China's salt-resistant hybrid rice should be the quickest and least expensive method.

    Fertilizer may not be necessary for saline-alkaline land. Nutrient replenishment comes from the sea.

    This is similar to nutrient replenishment on Egypt's Nile Delta. The river brings the fine silt along the banks of the Nile and the Nile Delta.

    Similarly, the sea should bring fine silt to saline-alkaline land in China.

    The ocean is full of nutrients to support plankton. Also, algae blooms occur periodically in the ocean (which indicates plenty of nutrients). Thus, the constant sloshing of ocean waves onto saline-alkaline soil should deposit a cumulative build-up of nutrients. This means fertilizer is unnecessary for saline-alkaline land.

    Why Chinese wasting so much resources and energy. They should stick to the synthetic rice buisness.

    There is plenty of silt along China's coastline saline-alkaline land.

    Rainwater and rivers move silt and organic material from the land into the sea. The ocean waves wash all of that silt back onto the saline-alkaline land.

    Good going, Why only china, entire world will benefit from it.

    You are absolutely correct. If China is successful in the next three years and delivers a salt-resistant strain of rice that yields 300kg of rice per "mu" of saline-alkaline farmland then the whole world benefits.

    It's just that I tend to cover new developments in China and I usually leave it in that context. However, China's salt-resistant rice can be planted in saline-alkaline farmland all over the world and there will be plenty of food for everyone.

    China won the Nobel Prize in Medicine, because China's artemisinin drug (also known as qinghao su, Chinese: 青蒿素) saved millions of lives from malaria all over the world.

    China's salt-resistant rice potentially has the same far-reaching impact. It could save millions of people from hunger.

    As far as it doesn't have any bad effects on health it is pretty good. It can help in producing food where fresh water is not available.
