Spanish tomato producers are exploring nanotechnology-based trace element formulations to address production pressures from rising input costs, labor shortages, and market demands for residue-free fruit. In 2024–2025, B+H Solutions GmbH partnered with a major Spanish tomato grower to evaluate the use of AgroArgentum® (silver) and AgroCyprum® (copper) under standard commercial greenhouse conditions. "The nanotechnology-based formulations demonstrated significant yield improvements, increased plant resilience, and residue-free production, providing a data-driven case for integrating colloidal silver and copper into intensive tomato cultivation strategies", the team shares.

Trial design and site
The trial was conducted under standard commercial greenhouse conditions. The formulations AgroArgentum® (silver) and AgroCyprum® (copper) were applied alternately on a weekly rotation via foliar sprays and irrigation according to B+H's protocol. The trial produced yields above expectations, approximately 30 % higher than regional benchmarks adjusted for greenhouse type and cultivar. Observations across the crop cycle reported uniform flowering, stable fruit set, and no visible abiotic or biotic stress symptoms. Losses of young plants after transplanting were near zero, and fruit quality was fully grade 1 A. "
Mechanism and integration
AgroArgentum® and AgroCyprum® deliver nanoscale trace elements that are bioavailable and compatible with fertigation systems. Weekly application via foliar sprays or irrigation provided controlled nutrient uptake without phytotoxicity and supported stable crop conditions. Trials in other crops, including olives and berries, indicate cross-crop consistency.

Residue and production management
Internal analyses confirmed zero-residue fruit, allowing a reduction in conventional chemical crop protection inputs. The approach can be integrated into commercial-scale greenhouse operations without infrastructure modifications. "This trial demonstrates the potential of nanotechnology-based trace element solutions to significantly increase productivity without increasing conventional inputs, and that our formulations can deliver in Mediterranean greenhouse production", the team shares. "It's an important step, as this approach aligns with the shift towards reduced pesticide residues, and environmental sustainability. It shows I'ts possible to grower with fewer conventional plant protection products."
B+H Solutions will attend Fruit Attraction 2025
