Abstract

Peat is increasingly scarce and expensive, making it a limited resource.
To ensure the commercial sustainability of tree production, it is essential to reduce costs by exploring alternative planting substrates that can totally or partially replace conventional black peat, a non-renewable resource.
One such alternative is biochar, a solid material produced through the thermochemical pyrolysis of biomass in the absence of oxygen.
Biochar has the potential to serve as an effective component in growth media for citrus seedling production.
Due to its high organic carbon content, biochar can significantly impact soil properties.
This study aims to assess the effects of growth media containing two different concentrations of biochar (25 and 50%) through genetic and agronomic approaches.
Over two years, the agronomic responses of citrus seedlings were analyzed by monitoring their growth.
At the meantime, the expression analysis of genes involved in the absorption of macronutrients (NH₄⁺, NO₃^–, P, and K) was gained insight.
