The Usefulness of Plant Growth EnhancersFeatured science projectScience project video


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.
