  • Module 2 – Water

    Water Water that is suitable for sandgardening is free of chemicals and pollutants.  It’s potable – which means that it’s fit for human consumption and, – by extension – fit for growing food. Water sources include: Rainwater Mains – the municipal supply Rivers and lakes Wells and ponds There’s everything to like about rainwater. It’s free – and it’s the…

  • 5.4.1. Nitrate in Depth

    Predicate All discussions of research papers on nitrate must be predicated with a caution. The 10 ppm of nitrate of the scientists, (the Hach test kit and the Lamotte test kit) is a 44 ppm test level of nitrate via the “normal” aquarium test kits (API aquarium test kit, the Seachem Multitest kit, the Sera…

  • Overcoming major bottlenecks in aquaponics – A practical approach (summary)

    great references on why AP is not good enough – also sectionsonnitratelevels Summary Aquaponics is the combination of fish production in aquaculture and hydroponic (soilless) production of crop plants. Despite of representing already a sustainable, innovative approach for future food production systems, aquaponics are still missing economic success and up to date major bottlenecks were…
