Coral sea sand has poor porosity, high pH, lack of organic matter, poor adhesion, poor nutrition, poor water holding capacity, so it is not suitable for growing agricultural crops for humans and livestock and does not bring economic efficiency to local people.
After a period of research, TUMIKI Institute of Technology has successfully developed a technological solution to quickly green up coral sand and sea soil.
The key to the success of coral sand reforestation technology is to retain water to provide moisture, limit water loss, and create a source of nutrients on the spot for native plants that thrive in harsh conditions. There are two main technological solutions to reforest coral sand: the technological solution that creates squares covered by low fences and the technological solution that does not include creating squares with fences. With the technological solution that does not include creating squares with fences, the following solutions are used: sandblasting to create small banks along contour lines; dividing small cells with biodegradable plastic fences or local materials; improving the surface soil to plant sea purslane; improving the soil in the holes planned to plant native plants as fences and to collect rainwater. Each solution has different technical characteristics and costs. Depending on the geographical characteristics and resources of each region, appropriate technological solutions are applied.
The use of these technological solutions helps shorten the time and increase the efficiency of converting coral sand into sea sand, helping to improve the livelihoods of local people.
