In the agro Romano, or zone immediately around Rome, land is as a rule left for pasturage.
Considerable trade is done in agro di limone or lemon extract, which forms the basis of citric acid.
Since 1884 the Italian Government have been systematically enclosing, pumping dry, and generally draining the marshes of the Agro Romano, that is, the tracts around Ostia; the Isola Sacra, at the mouth of the Tiber; and Maccarese.
The wheat crop in 1906 in the Agro Romano was 8,108, 500 bushels, the Indian corn 3,314,000 bushels, the wine 12,100,000.
Agro allows you to plow through the competition, swatting aside any car that gets in your way.
