nitrogen_free_plant_nutrient_solution_for_soybean_growth

CultureMech:015438 specialized DEFINED LIQUID
Original name: Nitrogen-free plant nutrient solution for soybean growth

Overview

pH
6.5
Notes
Vessel type: Leonard jars or pots with vermiculite Light regime: 16h light / 8h dark Light intensity: 250 Nitrogen-free growth medium for soybean to study symbiotic nitrogen fixation. Leonard jar system or vermiculite substrate watered with nitrogen-free nutrient solution. Plants inoculated with sfSynCom (Bradyrhizobium BXYD3 plus Pantoea helper strains) to assess nodulation efficiency and nitrogen fixation capacity.
