flag NUS scientists created biodegradable microneedle patches that deliver biofertilizer directly into plants, boosting growth and cutting fertilizer use by 15% or more.

flag NUS scientists have developed biodegradable microneedle patches that deliver biofertiliser directly into plant tissues, enhancing growth in vegetables like Choy Sum and Kale while reducing fertilizer use by over 15%. flag The patches, made from polyvinyl alcohol, dissolve within a minute upon contact, releasing beneficial microbes directly into leaves or stems. flag This method improves microbial delivery to roots, bypassing soil challenges like competition and pH shifts. flag Greenhouse tests showed increased biomass, leaf area, and height compared to soil-based application. flag The system uses a 3D-printed applicator for even distribution, enabling precise dosing and potential automation. flag The technology offers a promising solution for sustainable urban and vertical farming with reduced environmental impact.
