Clorose férrica induzida pelo calcário
Iron chlorosis is one of the most common and difficult to control problems in crops grown on calcareous soils.
In alkaline soils, which represent one third of the Earth surface, the bicarbonate ion prevails and is a major induction
factor of iron chlorosis. As a result, alkalinity limits Fe bioavailability in the soil solution, Fe reduction and
assimilation, as well as transport and uptake within the plant. Due to this nutritional imbalance, plants develop
different response strategies which are not entirely successful on calcareous soils. In consequence, yield, fruit
quality and harvesting season are negatively affected. Preventing and treating iron chlorosis is highly costly, but is
inevitable, in order to ensure crop sustainability in regions where soil calcium carbonate and aridity are limiting
factors. In this work, we present a short overview of Fe dynamics in calcareous soils and its influence on crop
