Technical Abstract: The major challenge for world agriculture today is to maintain food and water supplies that can meet the demands of a growing world population. The shortage of fresh water, and its use mainly for human consumption, leaves the farmers with the choice of using reclycled city water, or underground saline waters, to irrigate agricultural crops. Although the use of recycled waters and salinity-tolerant plants offer an imediate alternative to expand agriculture in the semiarid region, in the long run this route will lead to the increase in soil salinity of areas irrigated with these waters. This chapter discusses the effects of salinity on both soil and plants, ways to measure and estimate salinity, osmotic versus ionic shock in plants, interaction of Na+ and Cl- with plants, and presents the salinity threshold of several crops to salinity, according to published literature. This is the 11th chapter in the book “Manejo da Salinidade na Agricultura: estudos básicos e aplicados” (Management of Salinity in Agriculture: basic and applied studies) written by scientists from the National Institute of Science and Technology applied to Salinity (INCTSal), sponsored by the Ministry of Culture and Technology and by the National (Brazilian) Center for Research and Development, CNPq. The book integrates the knowledge on how salinity affects soils and plants, and links scientists who work in increasing the capacity building of Brazilian scientists and who advise graduate students majoring in crop production in saline soils or using saline irrigation water.
