Agriculture in Chile encompasses a wide range of different activities due to its particular geography, climate and geology and human factors. Historically agriculture is one of the bases of Chile's economy. Now agriculture and allied sectors like forestry, logging and fishing account for only 4.9% of the GDP  and employ 13.6% of the country's labor force. Some major agriculture products of Chile include grapes, apples, pears, onions, wheat, maize, oats, peaches, garlic, asparagus, beans, beef, poultry, wool, fish, timber and hemp. Due to its geographical isolation and strict customs policies Chile is free from diseases such as mad cow disease, fruit fly and Phylloxera. This, its location in the Southern Hemisphere, which has quite different harvesting times from the Northern Hemisphere, and its wide range of agriculture conditions are considered Chile's main comparative advantages. However, Chile's mountainous landscape limits the extent and intensity of agriculture so that arable land corresponds only to 2.62% of the total territory. Chile currently utilizes 14,015 Hectares of agricultural land.
