Summary
This 2011 study investigated the optimisation of nitrogen form ratios in hydroponic strawberry production, a practice relevant to protected cultivation systems. By manipulating ammonium-to-nitrate ratios in nutrient solutions supplied to 'Seolhyang' strawberries grown in inert substrate, the work measured impacts on plant biomass accumulation and mineral nutrient acquisition. The findings suggest that nitrogen source composition in soilless systems influences nutrient uptake dynamics, though the specific optimal ratio would require examination of the full dataset.
Regional applicability
Hydroponic strawberry production is practised in the United Kingdom, particularly in protected environments. However, the cultivar and optimal nitrogen ratios identified in South Korean conditions may require validation under UK climate and lighting regimes. The methodology and general principles are directly transferable to UK horticultural research and practice.
Key measures
Plant growth metrics; nutrient uptake rates; nitrogen form ratios in nutrient solution
Outcomes reported
The study examined how varying ratios of ammonium to nitrate nitrogen in hydroponic nutrient solutions affect growth performance and nutrient uptake efficiency in 'Seolhyang' strawberry cultivar grown in inert media.
