Water hyacinths, sargassum and other aquatic weeds spread rapidly and are pernicious aquatic weeds that negatively impact ecological adaptability, the environment, human life and health, and economic development. The major impact caused by this water hyacinth is, A. Siltation occurs in rivers, lakes, etc., reducing the volume and flow of water and significantly affecting agricultural irrigation, hydropower generation, drinking water, industrial water, and transportation facilities. B. The roots of the water hyacinth absorb atmospheric nitrogen, which interferes with oxygen supply, disrupts the ecosystem of fish and many aquatic organisms, drastically reduces the protein source for fish and shellfish, and is a source of mosquito breeding and other diseases, which greatly affects the health of the local population. C. Areas covered by whitebait will no longer be available for transportation or as aquaculture, and tourism in the water body will decline. D. If the water surface were to be closed by the water hyacinth, about three times the normal open water surface would evaporate, causing rivers and lakes to become more landlocked.
Waterweed experts around the world are discussing and trying various countermeasures, but have concluded that waterweed extermination cannot be a complete and permanent solution. While under normal conditions it takes about 52 days for the water hyacinth to grow, it takes only 22 days in contaminated water, where pollution from detergents and other sources of nutrients can be a source of nutrients. Due to the plant's strong reproductive capacity and the fact that the seeds remain for decades, it is said to be impossible to completely eradicate water hyacinth.
On the other hand, agriculture in Africa is said to be the least productive in the world because the high cost of chemical fertilizers makes it difficult for most farmers to use them on their farms. African farmland is not fertile, has few microorganisms, no water retention, low yields, and soil runoff as soon as it rains, which is always poor and only inorganic. This vicious cycle of chain food production needs to be broken. Many scientists believe that if water hyacinth can be converted into fertilizer, its high content of the elements nitrogen, phosphorus, and potassium would make it suitable for composting and could have a significant effect on increasing soil nutrients and help ensure a steady fertilizer supply. The main reason why the use of water hyacinth has not progressed is that there has been no effective way to dry water hyacinth with a high water content of 90% or more.
