NUS scientists created biodegradable microneedle patches that deliver biofertilizer directly into plants, boosting growth and cutting fertilizer use by 15% or more.
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%.
The patches, made from polyvinyl alcohol, dissolve within a minute upon contact, releasing beneficial microbes directly into leaves or stems.
This method improves microbial delivery to roots, bypassing soil challenges like competition and pH shifts.
Greenhouse tests showed increased biomass, leaf area, and height compared to soil-based application.
The system uses a 3D-printed applicator for even distribution, enabling precise dosing and potential automation.
The technology offers a promising solution for sustainable urban and vertical farming with reduced environmental impact.
Los científicos de la NUS crearon parches de microagujas biodegradables que entregan biofertilizante directamente a las plantas, impulsando el crecimiento y reduciendo el uso de fertilizantes en un 15% o más.
