Introduction
Increasing the efficacy of biostimulants to aid crop performance Biostimulants are known for being an environmentally friendly alternative to current fertilisers and plant protection products in the market. They can help plants grow by enhancing nutrient uptake as well as protect the health of crops by improving their tolerance to stress. The EU-funded NANOSTIMULANTS project aims to increase the effectiveness of biostimulants by developing a Nanostimulant.
