Abstract

Magnesium plays a key role in the growth of a plant by acting as the central atom of the chlorophyll molecule. This study is carried out to develop a low-cost multi-nutrient fertilizer by utilizing the bittern solution. This fertilizer is capable of fulfilling the Magnesium, Potassium and Calcium requirement of a plant effectively. A dilution series of bittern was prepared, and a series of tests was carried out to demonstrate the importance of multi-nutrient fertilizer to the growth of a plant. This fertilizer contains 1.27%, 0.31% and 0.01% of highly water soluble Magnesium, Potassium and Calcium respectively to cater the short term requirement of a plant. Developing an indigenous source of supply for fertilizer is important both for the agricultural and strategic reasons. The major drawback of conventional salt production has been overcome by using bittern to produce a multi-nutrient source for plants. It could also mitigate negative environmental impacts by successfully controlling pollutant discharge. Therefore, this novel process can be considered as a comprehensive solution towards sustainable development.

利用太阳能制盐废液开发多养分肥料

镁作为叶绿素分子的中心原子，在植物的生长中起着关键作用。以卤水为原料，开发一种低成本的多养分肥料。这种肥料能有效地满足植物对镁、钾和钙的需求。配制了一系列卤水稀释剂，并进行了一系列试验，以证明多营养肥对植物生长的重要性。高水溶性镁、钾、钙含量分别为1.27%、0.31%、0.01%，可满足植株短期需用。从农业和战略的角度来看，发展一个本地的肥料供应来源都很重要。通过使用卤水为植物生产多种营养源，克服了传统制盐的主要缺点。它还可以通过成功控制污染物排放来减轻对环境的负面影响。因此，这一新的过程可以被认为是实现可持续发展的全面解决方案。
