TITLE:

NATURAL NANOFERTILIZER: AGRICULTURAL APPLICATION AND CONTROLLED RELEASE OF NUTRIENTS

KEY WORDS:

HDLs; Nanofertilizers; Controlled release

PAGES: 70
BIG AREA: Ciências Exatas e da Terra
AREA: Química
SUMMARY:

The use of chemical fertilizers has contributed to an increase in environmental contamination. You
Double Lamellar Hydroxides (HDLs) are a class of synthetic anionic clays that are adsorbent
effective for removing a variety of contaminants, as they have excellent
anion exchange. For this reason, HDLs have aroused interest in several areas, including
research focused on agriculture. In this sense, the use of lamellar compounds as matrices
obtaining slow-release nutrient fertilizers can offer alternatives to aspects
agronomic, related to the reduction of the consumption of conventional fertilizers and, still, to reduce the
environmental impacts, thereby enabling agricultural and environmental benefits. Therefore, the objective
of this work is to synthesize and characterize the HDLs interspersed with humic substances, evaluating the
interaction with nutrients (phosphorus, nitrogen, calcium and magnesium), aiming at the production of a nanofertilizer
and investigate the controlled release behavior in agricultural systems in order to increase the
productivity.
