Meaning of "secano" in the Spanish dictionary

Rainfed agriculture is one in which the human being does not contribute water, but uses only that which comes from the rain. Olives from rain-fed olive trees have a higher yield than irrigated olive trees, since they do not have as much water and, therefore, their oil percentage is higher. In the northern hemisphere, it is known as temporary agriculture and is carried out from April to September. In Chile, it is known as rulo agriculture. La agricultura de secano es aquella en la que el ser humano no contribuye con agua, sino que utiliza únicamente la que proviene de la lluvia. Las aceitunas provenientes de los olivos de secano tienen mayor rendimiento que las de regadío, ya que éstas no poseen tanta cantidad de agua y, por lo tanto, su porcentaje de aceite es mayor. En el hemisferio norte, se conoce como agricultura de temporal y se realiza de abril a septiembre. En Chile, se conoce como agricultura de rulo.
