Označite | Izvleček: | Is an aquatic fern Azolla, Anabaena symbiont to make a plant, perfect in the nitrogen supply in rice cultivation where this fern is one of the great benefactors for the production of this grass organically. In this research seeing the benefits of Azolla as green manure, feed supplement for small animals and wastewater treatment, welcomed the idea of whether Azolla can capture and provide oxygen to the water where it is growing. Given that there are some species described Azolla in the world, was observed in the proximity of the research had two well-defined species such as: Azolla Filiculoides and Azolla Mexico, located at an altitude between 2900-3780 m.s.n.m. and 2500- 2780 m.s.n.m. respectively, giving other species bred for growing rice in Azolla Guayas Caroliana, there deposed three different species of property and uses. To see which of the three species and grows best fits, considering that the objective of the research is to quantify the amount of dissolved oxygen (DO) and Chemical Oxygen Determination (COD), which can provide water Azolla which provides . |
