Resumo(s)
Rice is the staple food of more than half of the world’s population, which is still growing.
The great dependence that agriculture, and rice specially, has on fertilizers alongside extreme events
that result from climatic change creates an urge for adaptation. Fertilizers are expensive, finite and a
potential environmental problem. Their precise application, by the use of slow-release nanofertilizers,
thus avoiding losses and consequently reducing the pressure on water resources, is one step forward
in this adaptation. It can reduce costs and protect the environment while ensuring food production.
Phosphorous is very important for rice, since it is involved in its flowering and root development,
and its low availability to the plants constitutes a serious problem. The delivery of phosphorous
through the crop cycle in the form of slow-release phosphorus nanofertilizer (Pnf) instead of the
conventional annual bulk application reduces the amount of nutrients applied and increases the
absorption by the crop. Combining the fertilizing effect with the use of natural stimulant compounds
such as chitosan can protect the crop from diseases and increase its resilience to stress. The use of Pnf
reduces the pressure on water resources and avoids imbalances in soil nutrients, thus responding to
climatic change challenges and abiotic stresses.
