From site visit, interview and observation, we will be able to match our result
with the literature review that we did. We will get to see and make comparison from
the real situation. For example, if we interview farmers who use only chemical
fertilizer with their entire farmland and they have been farming for quite sometime,
we can observe whether or not the soil at their land is damaged and if yes how bad is
it. We can also observe the health condition of this group of farmers if they are
affected physically by having been using a lot of chemical or not. For those who are
organic fertilizer users, we can observe the soil condition at their land and make
comparison between the soil that belongs to organic fertilizer users and chemical
fertilizer users.
