This experiment was conducted to find out the effectiveness of organic fertilizers in improving plant growth. The results of this experiment might help us improve crop yields.
Watering haseolus aureus (mung beans) with organic fertilizer (as opposed to inorganic fertilizers) will help them grow faster.

Organic fertilizers (like Hasta Gro) are safer to use compared to chemical fertilizers. Some chemical fertilizers can be dangerous to humans and animals. When it rains, the chemical fertilizers are washed off our lawns and drain into local water catchments (eg. our reservoirs, lakes and ponds). The fish and other aquatic life, as well as animals living in or around the ponds may be poisoned and die due to the toxic content in the chemical fertilizer.
The organic fertilizers may contain water, urea, extracts from seaweeds, some micronutrients, humic acid and some extracts from the process of fermentation. The compounds found in organic fertilizers help to increase the amount of microbes in the soil. This will help to change the composition of the nutrients in the soil so that they are more easily absorbed by plants.

The materials required for this experiment:
It is observed that the plant in group A will grow tall the fastest. The plant in group B and group C grow slower but at almost the same pace.
Use the graph below to plot the results of the table above.
The hypothesis that watering a mung bean plant with organic fertilizer will help it grow faster is proven to be true. The organic fertilizer contains nutrients required by the plant and the soil. By increasing the concentration of nutrients in the soil, the roots of the plant are able to absorb these nutrients more quickly and this speeds up growth, which will result in faster production of stems and leaves.
Chemical pesticides and fertilizers can be more effective then organic fertilizers. However these chemical pesticides and fertilizers are toxic and dangerous to both poeple and animals. When it rains these harmful chemicals drain into rivers or seep into the water table underground. Some of this water ends up in our reservoirs- the source of our drinking water!
Another problem with chemical fertilizers is that the presence of these toxic chemicals in ponds and rivers has been known to cause birth deformities in animals which are dependent on these water resources. With an increasing awareness of the harmful effects of chemical fertilizers, the use of organic fertilizers should be encouraged among consumers.
What would happen if the experiment was repeated using different types of soil like sand, clay etc?
The experiment can be repeated to compare the use of organic fertilizers and chemical fertilizers.
