3. FUNCTION
With the fertilizers we
can improve the
characteristics of the
land. They make the
transport of the
nutrients from the
ground to the plants
easier, so we will have
more vegetables and
they will have a better
quality.

4. TYPES OF FERTILIZERS:
1. Organic: They are made using just natural products.
2. Inorganic: They are made with many chemical products.
*There are a lot of different types of each one.

5. ORGANIC FERTILIZERS
For our small
vegetable garden, it will
be better to use organic
fertilizers, because they
are cheaper and the
land will absorb this
kind of fertilizer more
slowly, so we'll need
less amount of
fertilizers.

6. INORGANIC FERTILIZERS:
The inorganic fertilizers
are better for the industrial
production of big vegetable
gardens. After a long time
these fertilizers could be
worse, because they are
made of chemical products,
that could produce
secondary effects. They are
more expensive.

7. CONCLUSION
For these reasons we are going to use
organic fertilizers. There are different types of
organic fertilizers that you can buy in a
gardening shop, but instead of buying it, we
will make it.
We are going to make a type of organic
fertilizer that is known as compost.

8. HOW TO MAKE THE COMPOST?
• The following video is going to explain us, the
proccess to make our own compost. And what
materials we are going to need to produce it.
