Italy is a country that predominantly has a Mediterranean type of climate, apart from the far north of the country. This means that Italy is a relatively dry country, with lot of sunshine throughout most of the year, and the precipitation is seasonal. Agriculturally, it is very important to notice that Italy has a relatively long vegetative season, unlike Germany.
The tomatoes are one of the most common agricultural products in Italy, and this is due to the conditions that the tomatoes require for their growth, and Italy as country has the prefect natural conditions for it.
