      <dc:description>The conversion of spent coffee grounds (SCG) into hydrochars has been the subject of&#xd;
extensive research in recent years, aimed at evaluating their potential for biofortifying foods and&#xd;
mitigating the plant toxicity linked to SCG. This study aimed to assess the physicochemical characterization&#xd;
and the impact of incorporating both activated (ASCG and AH160) and functionalized&#xd;
SCG (ASCG-Zn), as well as SCG-derived hydrochars (AH160-Zn), on cucumber yield and plant zinc&#xd;
content. The following physicochemical properties were analyzed: specific surface area, pH and&#xd;
electrical conductivity, polyphenols, and nuclear magnetic resonance. The by-products activated and&#xd;
functionalized with zinc were applied to cucumber crops grown in a greenhouse across multiple&#xd;
harvests. The activation of both SCG and H160 reduced the specific surface area of the particles.&#xd;
However, when these by-products were functionalized, their Zn content increased significantly, up&#xd;
to 7400 ppm. Concerning polyphenol content, the activated products showed levels ranging from&#xd;
3.5 to 4.9 mg GAE/g. Regarding cumulative production, the treatments that showed the highest&#xd;
yields were the by-products activated and functionalized with Zn reaching 25 kg. Incorporating&#xd;
these by-products notably raised the Zn content in cucumbers, reaching 0.1 mg Zn per 100 g of fresh&#xd;
weight. The activated by-products demonstrated the highest Zn utilization efficiency.</dc:description>
