Sustainable agriculture calls for the development of eco-friendly materials that possess desired properties and functionalities. In this study, the effect of incorporating lignin-grafted poly(ε-caprolactone) (LN-PCL) into a PCL matrix was evaluated. LN-PCL was synthesized by ring-opening polymerization (ROP), yielding polymers with varying PCL degrees of polymerization (DP 26–101) and amphiphilic properties. Incorporating LN-PCL into PCL films enhanced hydrogen bonding, crystallinity, and doubled Young’s modulus. SEM analysis showed smoother surfaces with higher DPs, while lower DPs reduced the contact angle from 78° to 68°. LN-PCL films absorbed >98% UVAB and >94% UVC light regardless of DP and degraded within 30 days. Release studies indicated controlled release rates of ATZ (<16%) and MTZ (46%) over 10 weeks. Overall, the UV protection, surface, mechanical, and controlled release properties of the LN-PCL/PCL films support the potential of these films as a carrier for chemicals with applicability in agriculture.

A naturally occurring metalloid selenium (Se) has been shown to be a necessary trace element for both humans and animals. There is a complex relationship between Se and crops, with both promoting inhibitory effects, which could be connected to variations in Se application methods, application concentrations, and application stages. Recently, Se has received a great deal of attention because of its significance and contradictory nature. This review compiles the main literature results of the impacts of different application methods, concentrations, and stages of Se on crops, examining how various plant species respond to Se and how they interact with abiotic stress. It is anticipated that this will demonstrate the viability and benefits of Se biofortification for various crop requirements and will be favorable to increasing the range of applications for Se biofortification.
