The Introduction Prepared by: Gab Macas

The earth’s atmosphere is made up of 78% nitrogen and it is essential to healthy plant growth. Without nitrogen, green plant are weak and smaller than they should be. Nitrogen helps our plants to build protein, but although nitrogen is already available in the air, plants are unable to utilize nitrogen directly.

Legumes are members of the pea or bean family. Some legumes are capable of providing a readily- available source of nitrogen to our soil.

Legumes have rhyzobium bacteria in their root nodules. These bacteria are able to take nitrogen directly from the atmosphere and fix it into the soil, this is due to the mutuality symbiotic relationship with bacteria found in some legume plants.

 Main problem: ◦ What type of legume plant fixes more nitrogen into the soil?  Sub problem ◦ Is there any significant difference between the different types of legumes in terms of:  Nitrogen fixation into the soil  Fertility of the soil after the legume plant fix nitrogen into the it?

 There is no significant difference between the ability of different types of legumes in fixating nitrogen in the atmosphere to the soil.

 To know what kind of legume fixes more nitrogen in the atmosphere into the soil  To know how fertile is the soil after the nitrogen in the atmosphere fixes into the soil by laboratory soil- testing or in a practical way such as repetitive planting

 For me and my co-students ◦ This study will give us additional knowledge in agricultural matters.  For the farmers ◦ This study will give them an alternative way in making soil fertilizer.  For legume plant consumers ◦ This study will help some of them to have an extra income due to the soil that they used in planting their legume plant.

This study was conducted in _______________ for ______ days during the academic school at the researchers' residences. This study is limited only in knowing which type of legume fixes more nitrogen in the atmosphere into the soil. It will not go further such as quantifying the amount of nitrogen that is present in the soil.
