Conclusions:
From the experiment that our group conducted in class, we can conclude many
things about the different needs that plants require to grow successfully. We also can
conclude which soil, sand, and polymer mixtures are most efficient in growing tomato
plants.
The first set of conclusions that can be drawn about this experiment, are the basic
requirements that tomato plants have in order to successfully live and grow. The first
requirement that we observed is that all plants require adequate light exposure each day;
preferably about 8-12 hours every day. Another requirement that plants have, no matter
what types of soils they are planted in, is an adequate water supply. We have observed
that each tomato plant requires at least 75 ml. of water every 2-3 days.
Many conclusions can also be drawn about what types of soils tomato plants can
be successfully grown in. First, we found that it is quite difficult to grow tomatoes in 400
ml. of soil, and two tablespoons of baby diaper polymer. Because the polymer holds
water for several days, regular watering is not needed. Therefore, if you are growing
tomatoes with baby diaper polymers, then you should only water the plants sparingly. If
you water the plants containing soils with baby diaper polymers excessively, the plants
will not grow and will eventually die. The next conclusion that we can state is that plants
grown in vermiculite only can grow successfully with watering done every 3-5 days.
Vermiculite is a polymer; therefore regular watering like you would do for other types of
plants grown in regular soils is not needed. Another conclusion can be drawn about
tomato plants grown in 400 ml. of sand, and two tablespoons of baby diaper polymers.
We concluded that tomato plants could be grown in sand and baby diaper polymers with
watering done about every 3-6 days. Tomato plants that are grown in a combination of
soil and perlite can grow very well with regular watering done every 2 days. Tomatoes
grown in 400 ml. of cow manure can also grow successfully with regular watering and
sufficient sunlight everyday. The next conclusion is that tomatoes can be grown well in
400 ml. of sand and two tablespoons of vermiculite. With regular watering (every 2
days), the plants will grow very successfully. And finally, plants that are grown in plain
soil with regular watering can also grow successfully.
So finally, from this project we can conclude that it is possible to experiment and
attempt to grow tomato plants in different types of soils, fertilizers, and polymers. We
can also conclude that plants have specific requirements that need to be met in order for
successful growth. Finally, the last and probably one of the most important conclusions
that we can draw from this experiment is that we found tomato plants grown in 400 ml. of
regular soil, and two tablespoons of perlite, can grow most efficiently compared to all of
the other combinations of soils, and polymers that we tested.
