The historic provinces of Walachia, Transylvania, Moldavia, Dobruja, and the Banat have distinct soil and climatic conditions that make them suitable for different types of agriculture (see Climate , ch. 2 Land , this ch.). The breadbasket of Romania is Walachia, which provides half the annual grain harvest and roughly half the fruit and grapes. Truck farming, especially in the Ilfov Agricultural District surrounding Bucharest, is also important. Despite the fertility of Walachia's soil, yields fluctuate considerably from year to year because of recurrent droughts. Transylvania, which receives more precipitation than Walachia, has poorer soils and more rugged terrain that restricts large-scale mechanized farming. Livestock raising predominates in the mountains, and potatoes and grains are the principal crops in the central basin. Moldavia has generally less fertile soil than Walachia and receives scant rainfall. Its primary crops are corn, wheat, fruit and grapes, and potatoes. The Banat region has a nearly ideal balance of rich chernozem soils and adequate precipitation. Grain, primarily wheat, is the principal crop fruits and vegetables are also important. Dobruja, a region of generally inadequate rainfall, was becoming agriculturally more important during the 1980s, because much of the marshland in the Danube Delta was being drained and brought under cultivation. The traditional crops of Dobruja are grain, sunflowers, and legumes.
