How much are we using Agricultural Chemicals?

According to this data, Japan is the most agricultural chemicals quantity consumed per unit area in the world.

Original data is OECD

Upper graph

X is year ( 1990-2004)

Y is Agricultural chemicals quantity used ( kgs/ha)

Actually it is not data contains whole country in the world.

Even though, Japan is using many agricultural chemicals.

This data is on quantity per unit area(ha).

Usually, horticulture farming is used more chemicals than grain farming.

It might be one reason for the graph…

However, Neatherlands, South Korea, these are small country and horticultural farming area, are using agricultural chemicals lesser than Japan.

And also…

This data is quite old(1986)

Even though, we can see how much agricultural chemicals Japanese rice farmer had used on that time, especially herbicide.

It is just on the data. I’m not sure in the real.

Because this data is on JPY.

Everyone knows Japanese commodity price is too high.

…

They used too much…

I think the reason.

1. Japanese customer is too strict for products.

They might complain if the products has insect or disease.

and also they prefer perfect form.

2.Japan has monsoon season. And also Japan has only small agricultural area.

…

These are some reason regarding to agricultural chemicals usage in Japan.

･･･

If they use so much chemicals, we must worry about the products. There are too much poison.

…

We should produce foods from healthy soil. And the foods from healthy soil has resistance to insect and pest.

However, some farmers are not considering their soil. They consider only the products form.

…
