Iron deficiency chlorosis in plants is often associated with soil conditions that appear to restrict exchange of gases with the atmosphere, such as fine texture, lack of aggregation, excessive moisture, or discontinuity in the profile in the form of plowsole, hardpan, claypan, or stratified deposits. These conditions can cause CO2 to accumulate in the soil and, particularly in calcareous soils,...

Water deficit and iron nutritional deficiency (iron chlorosis) are frequent environmental stresses affecting grapevine production in the Mediterranean region. The objectives of this work were (i) to study combined effects both on aromatic profile Tempranillo grapes, occurring simultaneously vineyard, (ii) evaluate viability foliar chlorophyll content at veraison (Chl) early assess quality poten...
